Background/Context: Seasonal researchers have developed a theory and hypotheses regard-
ing the importance of neighborhood and school contexts for early childhood learning but
have not possessed nationally representative data and precise contextual measures with
which to examine their hypotheses.
Purpose/Research Questions: This empirical study employs a seasonal perspective to assess
the degree to which social context and race/ethnic composition—in neighborhoods and
schools—affect the reading achievement growth of young children. The authors ask, Were
there specific seasons when context and/or composition were particularly salient for reading
achievement? Also, did accounting for context and composition challenge established
appraisals of the relationship between family factors and achievement?
Population: Data for a nationally representative sample of students proceeding through
kindergarten and first grade came from the Early Childhood Longitudinal Study-
Kindergarten Cohort (ECLS-K). Neighborhood social and race/ethnic measures came from
the 2000 Census. Research Design: This quantitative study employs a three-level model that
assesses reading achievement at school entry and during three subsequent seasons. The
model represents reading achievement as a time-varying process at level 1, conditional upon
family socio/demographic factors at level 2, and dependent on social context and

Socioeconomic Context and Racial Composition 1339
Findings/Results: Neighborhood social context mattered substantially for students’ reading
achievement levels at school entry and for their reading achievement growth during the sum-
mer. The proportion of neighborhood residents from minority race/ethnic groups was not
associated with reading achievement at school entry or during the summer season. During
the school year, school social context was associated with reading growth during kinder-
garten, and school social context and race/ethnic composition were associated with reading
growth during first grade.
Conclusions/Recommendations: The magnitude and frequency of contextual effects found
in this national sample have considerable implications for achieving educational equality
in the United States. The authors recommend that policy makers attend to the quality of
neighborhood and school settings as a means of promoting literacy development for young
children.
The skills that young children possess when they enter elementary school
and the pace at which they learn while in elementary school matter a
great deal for subsequent academic outcomes and life experiences.
Differences in elementary school learning progress typically become dif-
ferences in high school graduation, college attendance rates, and even-
tual adult status (Entwisle & Alexander, 1999; Kerckhoff, 1993). During
the early primary school years, seemingly small month-to-month achieve-
ment differences accrue across seasons, resulting in substantial differ-
ences as students prepare to enter high school.
By the time students in the United States enter high school, socially dis-
advantaged students and students from minority race/ethnic groups lag
substantially behind their more advantaged and majority counterparts in
fundamental reading skills. Among U.S. eighth graders in 2005, only 57%
of students eligible for free lunch were reading at or above the basic level,
whereas 81% of those not eligible for free lunch were exceeding this level
(U.S. Department of Education, 2005). Similar gaps exist between White
students and Hispanic students, and even wider gaps separate White and
African American students. Although the presence of these gaps is com-
mon knowledge among education researchers, their source has been the
subject of several theories and considerable debate. Disagreement has
extended to questions of when, where, and how these gaps emerge.
Seasonal researchers have identified a blind spot in much of the edu-
cational research on achievement gaps. Research studies based on
annual achievement testing have conflated processes that take place out-
side the school year with those taking place during the school year
(Alexander, Entwisle, & Olson, 2004). In contrast, seasonal researchers
have emphasized that participation in formal schooling varies decisively
across seasons—especially in the United States1—and thus shined a light
on processes taking place at times other than the school year and in
1340 Teachers College Record
places other than school. This approach has led to a fundamental reap-
praisal of the relationship between families, schools, and early childhood
learning. Seasonal researchers have concluded that the processes by
which young students from socially disadvantaged families often fall
alarmingly behind in their academic development occur, in large part if
not entirely, during the summer season, when schools are typically not in
session (Downey, von Hippel, & Broh, 2004; Entwisle, Alexander, &
Olson, 1997; Heyns, 1978). The summer setback disproportionately
affects African American and Hispanic students because they are more
likely than White students to come from low-SES families.
The seasonal perspective has substantial implications for educational
research. It is a call for precise testing and data collection schedules that
facilitate indentifying the periods and locations of achievement gaps
(Heyns, 1978). In particular, the perspective emphasizes the distinction
between school-year and summer-season processes and points to families
and schools as locations with potentially divergent effects—especially for
low-SES students—on achievement inequality. We adopt this analytical
perspective and extend it beyond the family setting, taking into account
the social context and race/ethnic composition of neighborhoods and
schools. We refer to social context as the socioeconomic character of neigh-
borhoods and schools. Race/ethnic composition refers to the makeup of
neighborhoods and schools in terms of the proportion of members from
majority and minority race/ethnic groups. When speaking broadly, we
use the term context to refer to both social context and racial composi-
tion. By adding consideration of context to the seasonal perspective, we
can ask questions regarding the relative contributions of families and
context to achievement inequality during nonschool periods and the
contributions of families, schools, and context during the school year.
To identify the characteristics of specific contexts in which young stu-
dents grow up and attend school, we constructed a unique data set that
links measures of neighborhood social characteristics from the 2000
Census—via residential zip codes—to individual students from the
kindergarten cohort of the Early Childhood Longitudinal Study (ECLS-
K), sponsored by the National Center for Education Statistics (NCES).
We drew on the detailed accounting of test times and school-year begin
and end dates within the ECLS-K database to decompose precisely
school-year and summer-season growth patterns. Using data from both
census and NCES sources, we used an identical coding process to con-
struct comparable contextual measures for neighborhoods and schools.
Using three-level growth models, we combined our accounting of sea-
sonal growth patterns based on NCES achievement tests and testing
schedules, accurate measures of student and family characteristics, and
Socioeconomic Context and Racial Composition 1341
contextual measures for neighborhoods and schools. We focused on
reading achievement because reading skills are the primary focus of
instruction during the first 2 years of elementary school.
Our findings indicate that neighborhood social context mattered sub-
stantially for students’ reading achievement levels at school entry and for
their reading achievement growth during the summer. On the other
hand, we found that the proportion of neighborhood residents from
minority race/ethnic groups was not associated with reading achieve-
ment at school entry or during the summer. During the school year, our
findings generally indicate that school context was more salient than
neighborhood context. School social context was associated with reading
growth during kindergarten, and school social context and race/ethnic
composition were associated with reading growth in first grade. These
contextual effects tended to reinforce longstanding patterns of socioeco-
nomic and race/ethnic achievement inequality and thus have consider-
able implications for educational equality in the United States.
BACKGROUND
THE SEASONAL PERSPECTIVE ON FAMILY SES AND ACHIEVEMENT
INEQUALITY
Seasonal researchers have reconceptualized early childhood learning for
low-SES children as a seasonally varying process in which lower status
families do not possess the resources necessary to continue academic
learning when school is not in session. This seasonal perspective differs
fundamentally from a more pessimistic view in which the families of low-
SES children are seen as impeding the process of academic learning dur-
ing the school year. Unfortunately, this more pessimistic view followed
somewhat rationally from studies such as the Coleman report (Coleman
et al., 1966). The annual achievement tests on which the Coleman study
was based prevented researchers from disentangling the relative contri-
butions of families and schools to achievement growth. Using more
recent semiannual testing data, seasonal researchers have found that stu-
dents’ participation in formal schooling produces a much more egalitar-
ian distribution of achievement growth than does the immersion of
students in their nonschool environments during the summer season
(Downey et al., 2004; Entwisle et al., 1997; Heyns, 1978).
Seasonal researchers have been unanimous in their conceptualization
of schooling as an equalizing force, although they have disagreed some-
what on the extent to which it overcomes the influence of family socioe-
conomic factors. The pioneer of seasonal learning research, Barbara
1342 Teachers College Record
Heyns (1978), conceptualized schools as a countervailing force to family
socioeconomic resources while maintaining that “the socioeconomic
background and general family conditions of children exert an influence
on the achievement of children, whether or not school is in session” (p.
186). Entwisle et al. (1997) went a distance further when arguing that
schooling overcomes limitations posed by home environments.
According to their faucet theory,2“Home resources do not ‘add on’ to
school resources in winter, because poor children do as well as those who
are well off. Only in summer do home resources come into play” (p. 38).
Systematic variation in school quality may also impede the role of schools
as an equalizing force. Downey et al. (2004) addressed this issue by assert-
ing that even though schools may be unfair in their allocation of learn-
ing resources, they still serve as “equalizers” because schools, as a whole,
are fairer than nonschool learning environments.
Findings from seasonal studies reveal greater socioeconomic disper-
sion in achievement scores during the summer than the school year.
Heyns (1978) found that during the summer season, each of her socioe-
conomic indicators—family income, parental education, and household
size—significantly predicted achievement, whereas during the school
year, only parental education significantly predicted achievement, and
much less so than during the summer.3Using categorical measures of stu-
dents’ families’ SES when examining test results from Grades 1–5,
Entwisle et al. (1997) found that the reading achievement level of high-
SES students exceeded that of low- and medium-SES students entirely
because high-SES students continued to grow in reading achievement
during the summer. While low- and middle-SES students did not grow in
reading achievement during the summer, they grew at least as quickly as
high-SES students during the school year; in 2 of the 5 years, middle-SES
students grew faster than high-SES students (Entwisle et al., table 3.1).
Using data from the ECLS-K database, Downey et al. (2004) found that
family SES was positively associated with rates of school-season learning
in reading but that the relationship was much weaker than during the
summer season.
RACE/ETHNICITY AND ACHIEVEMENT INEQUALITY
The Persistent Black-White Achievement Gap
When addressing race/ethnic disparities in achievement within the
United States, researchers have tended to focus on the achievement gap
between African American and White students. National high school sur-
veys have consistently revealed a gap on the order of one standard devia-
Socioeconomic Context and Racial Composition 1343
tion between composite—reading and math—achievement scores for
Black and White students (Hedges & Nowell, 1998). During the period
from 1965 to 1992, this gap narrowed in most subjects. For example, in
reading achievement, the Black-White gap narrowed from -1.0 standard
deviation units to -0.70 units (Hedges & Nowell). Given the size and per-
sistence of this gap, researchers have devoted a great deal of considera-
tion to exactly when and how the Black-White gap emerges (Jencks &
Phillips, 1998). With few exceptions, researchers have noted consistent
disparities in achievement test scores between Black and White students
at school entry (Phillips, Brooks-Gunn, Duncan, Klebanov, & Crane,
1998). The picture of the gap that emerges after school entry is more
complex, and the gap sizes vary by specific subject. In a study that
employed all the national high school surveys along with results from the
National Assessment of Educational Progress (NAEP), Phillips et al.
attributed half of the Black-White gap in high school tests to occurrences
after the beginning of school but before high school. Black students who
entered elementary school with the same scores as White students tended
to fall behind White students on reading and vocabulary measures but
tended to keep up in mathematics. These findings suggest that
researchers should be attuned to the emergence of Black-White achieve-
ment gaps during elementary school, especially in the area of reading
skills.
Race/Ethnicity and Achievement Inequality in Seasonal Research
Seasonal researchers have demonstrated a clear concern for
race/ethnic achievement inequality as evidenced by the conduct of land-
mark seasonal studies in the Atlanta (Heyns, 1978) and Baltimore
(Entwisle et al., 1997) urban core areas, each of which had majorities of
African American students during the study periods. The primary focus
of these studies, however, has been seasonal variation in the relationship
between family SES and achievement. Certainly, achievement inequality
rooted in socioeconomic inequality has implications for minority stu-
dents, who are more likely than White students to come from low-SES
families. However, other researchers have emphasized that a substantial
Black-White achievement gap remains even when accounting for family
SES (Phillips et al., 1998).
When controlling for SES, seasonal researchers have tended to find
that race/ethnic achievement gaps do not widen substantially during the
summer season. In a meta-analysis of 39 previous summer learning stud-
ies, Cooper, Nye, Charlton, Lindsay, and Greathouse (1996) found that
achievement growth rates for Black and White students from families
1344 Teachers College Record
with similar income levels slowed equally during the summer. Similarly,
using data from the ECLS-K and controlling for family SES, Downey et al.
(2004) found that African American, Hispanic, and White students did
not differ significantly in summer-season reading and math achievement
growth. However, also studying students from the ECLS-K, Burkam,
Ready, Lee, and Logerfo (2004) found a summer-season Black-White gap
in math achievement growth. In her seminal study of Atlanta public
school students, Heyns (1978) found that net of family income and
parental education, African American students’ composite achievement
scores grew at a slightly slower pace than those of White students during
the summer.
Seasonal studies have more consistently found school-year race/ethnic
gaps in achievement even when controlling for family SES. Using data
from the ECLS-K, Downey et al. (2004) identified substantial Black-White
gaps in school-year reading growth during kindergarten and first grade,
and a modestly sized Hispanic-White achievement gap during first grade.
Both Entwisle and Alexander (1992), from their Beginning School Study
(BSS) sample of Baltimore students, and Heyns (1978), in her sample of
Atlanta sixth- and seventh graders, found school-year differences
between Black and White students. Taken together, these findings and
the summer-only studies suggest that after school entry, the school year—
rather than the summer—is the primary period during which
race/ethnic dispersion in test scores increases.
CONTEXT AND EARLY CHILDHOOD LEARNING
The Challenge of Defining the Boundaries of Context and Composition
Researchers who have refined social theory concerning the effects of
neighborhood and school context have conceptualized context as perti-
nent to groups of people bounded by geography (such as neighborhood
boundaries) or by organizational location (such as attendance at the
same school). Geographic bounding brings together fairly large4and
potentially diverse groups of individuals. Delineating boundaries have
included school catchment areas, census tracts, and zip code tabulation
areas (Jencks & Mayer, 1990). The conceptualization of neighborhoods
and schools as geographic areas that include all members within them
differs from the notion of a social network, which groups more specific
sets of people who regularly interact with each other (Wasserman &
Faust, 1994). Even poor neighborhoods provide a range of potential rela-
tionships (Jencks & Phillips, 1998). When working at the neighborhood
or school level of aggregation, the researcher cannot know if all of a per-
Socioeconomic Context and Racial Composition 1345
son’s important and immediate social relations are contained within his
or her neighborhood or school.
Despite the potential for considerable variation in social interactions
within contexts, contextual research has proceeded according to a set of
reasonable assumptions. Within geographic areas with a fair degree of
socioeconomic homogeneity, processes of social interaction and access to
social resources take on patterns that influence the lives of individuals
and families. Depending on the quality and content of these patterns,
context can positively or negatively influence individual development.
Empirical findings from this body of research have tended to validate this
hypothesis. Researchers have found that contexts—in ways that can vary
from person to person, group to group, and place to place—significantly
influence the actions and development of individuals within them, inde-
pendent of one’s immediate family environs (Brooks-Gunn, Duncan, &
Aber, 1997; Brooks-Gunn, Duncan, Klebanov, & Sealand, 1993; Jencks &
Mayer, 1990).
Social Context and Early Childhood Learning
Two main theoretical perspectives have evolved to explain the relation-
ship between context and the cognitive development of young children.
The collective socialization perspective has conceptualized contextual
effects as consisting of parental actions relevant to other parents and chil-
dren in a neighborhood. Affluent parents are seen as promoting good
parenting among other parents and as exerting a degree of social control
over their children’s peers by discouraging undesirable behavior
(Ainsworth, 2002; Brooks-Gunn et al., 1993). This perspective empha-
sizes the positive role modeling provided by more affluent neighbors. For
this reason, research informed by this perspective tends to include vari-
ables intended to capture the positive effects of socially advantaged
neighbors or classmates.
An alternative conceptualization suggests that institutional resources,
especially the human resources provided by middle-class service person-
nel, form the crux of important content present in a context. Concern
for capturing the scope of institutional resources available to residents
has dovetailed with concern about their social isolation and has led to
measures indicating the proportions of disadvantaged residents in neigh-
borhoods (Wilson, 1987). Within this resource-based approach, large
proportions of disadvantaged residents are seen as limiting the amount
of economic support available for hiring well-qualified teachers, main-
taining storefront businesses, attracting quality health care facilities, and
encouraging respectful policing strategies. A feedback relationship takes
1346 Teachers College Record
place such that the presence of disadvantaged residents leads to the
absence of advantaged residents and the institutions that they sustain.
Because of this linkage, analyses that rely on separate measures of contex-
tual advantage and disadvantage have tended to produce smaller coeffi-
cients than those that rely on one or the other. However, multicategory
analyses have allowed researchers (e.g., Brooks-Gunn et al., 1997) to
compare effect sizes for low- and high-SES residents and thus have pro-
vided a clearer picture of the sources of observed contextual effects.
Findings From Neighborhood and School Social Context Studies
Findings from quasi-experimental studies have revealed significant and
modestly sized associations between social context and the cognitive test
scores of young children. Brooks-Gunn et al. (1993) found a substantial
positive relationship between the proportion of higher income residents
in a neighborhood and early childhood test scores. Using the Stanford-
Binet measure of IQ5administered to children at 36 months of age, the
Brooks-Gunn research team found that a one-standard-deviation increase
in the proportion of affluent neighbors was associated with an increase of
one quarter of a standard deviation in individual IQ test scores. The
authors found no negative effects associated with the proportion of poor
neighbors. The multisample study (Brooks-Gunn et al., 1997) of which
this study was a part created a consensus that neighborhoods matter for
early childhood cognitive development. In a national study of high
school students, Ainsworth (2002) found a significant positive relation-
ship between the neighborhood proportion of affluent residents and
achievement test scores.6
Regarding school social context, Jencks and Mayer’s (1990) reappraisal
of data from the Coleman report (1966) found that mean school SES was
positively associated with achievement levels in core subjects during the
sixth grade. The authors estimated the effect of moving from a poor
school to a middle-class school as worth an increase of approximately one
sixth of a standard deviation in achievement, and this effect held for
Black and White students. Results from this study should be interpreted
with caution; Coleman relied on student-reported SES measures and may
have inadequately controlled for prior achievement. More recently,
researchers using greatly improved measures of family SES and school
context have not detected a relationship between school social context
and achievement growth for high school students (see Gamoran, 1987).
These findings suggest that school social context may be most conse-
quential for achievement growth during early childhood.
Socioeconomic Context and Racial Composition 1347
Findings from Residential Mobility Studies
Evaluations of residential mobility programs have produced mixed find-
ings regarding the relationship between improved neighborhood social
context and educational outcomes. In a quasi-experimental evaluation of
the Gautreaux residential mobility program, Kaufman and Rosenbaum
(1992) found modest achievement benefits associated with relocation of
poor families to suburban neighborhoods. In an experimental evaluation
of the Moving to Opportunity (MTO) program, Sanbonmatsu, Kling,
Duncan, and Brooks-Gunn (2006) found no achievement benefits associ-
ated with relocation of poor families from high-poverty to low- and
medium-poverty neighborhoods. Although they operated by different
rules, these programs sought to improve education and labor market out-
comes by relocating families from high-poverty, largely African American
public housing locations to less poor and less segregated locations in
urban metro areas.7
Between 1976 and 1998, the Gautreaux program moved more than
7,000 families from Chicago public housing to privately leased apart-
ments and houses in the Chicago city area and throughout the Chicago
metro area. When comparing origin and placement addresses, neighbor-
hood poverty dropped from 42% to 17%, and neighborhood percent
African American dropped from 83% to 28% (Duncan & Zuberi, 2006).
However, neighborhood social context and race/ethnic composition dif-
fered markedly depending on whether families relocated to city or sub-
urban areas. Researchers have exploited this difference to compare
outcomes for parents and children in these different settings. Location in
suburban versus city areas was associated with equal marks in school8and
with a greater likelihood of placement in the college-bound track in high
school (Kaufman & Rosenbaum, 1992). Criticism of findings from the
Gautreaux quasi-experimental evaluations centered on the inability,
posed by the program design, to identify control groups not tainted by
selection bias (see Duncan & Zuberi).
The MTO program was designed to remedy this selection problem
through random assignment of enrollees to experimental, Section 8, and
control group conditions (see Orr et al., 2003). The program offered
public housing residents and applicants in five cities the opportunity to
enroll in a lottery, with a two-thirds chance of moving to a low-poverty
neighborhood. On average, mobile families relocated from neighbor-
hoods with more than 50% poverty to neighborhoods with 11% and 28%
poverty for the experimental and Section 8 groups, respectively (Orr et
al.). A comprehensive evaluation of achievement outcomes for 5,000 chil-
dren who changed neighborhoods as part of the MTO program found no
1348 Teachers College Record
significant improvements in test scores (Sanbonmatsu et al., 2006). This
finding held even for the youngest children in the program, who were
preschoolers at the time that their families moved.
Findings from Gautreaux and MTO suggest several necessary condi-
tions for changes in context to make a difference for students. The
Gautreaux evaluation clearly suggests that changes in settings must be
substantial to make a difference. The Gautreaux students who demon-
strated better marks and track placements had relocated to suburban
neighborhoods and schools remarkably different from their original
locations. Placements within the MTO program reduced the poverty lev-
els of participant families’ neighborhood settings but often did not
change students’ school settings. Some students continued attending
their inner-city schools of origin,9and others moved to schools with only
modestly lower rates of poverty than their origin schools (Duncan &
Zuberi, 2006). Thus, the MTO findings suggest that relocation programs
that generate only modest contextual improvements or that do not
address school context and quality are unlikely to improve achievement.
Social Context and Achievement in Seasonal Research
Heyns (1978) noted important differences between the test scores of stu-
dents from poor and nonpoor schools10 in her sample of sixth- and sev-
enth graders from Atlanta. She found less social dispersion of
school-season learning rates among students in schools with majorities of
nonpoor students, as well as an interaction between family income and
school context. The reading skills of lower income11 White students grew
at a considerably faster pace when they attended nonpoor schools. Black
students in nonpoor schools also appeared to learn at faster rates than
those in poor schools, but these differences—when comparing students
from equal income groups—were not statistically significant. Heyns cau-
tiously concluded that the nonpoor schools in her sample appeared to be
doing a better job of equalizing learning growth for students from differ-
ent social backgrounds.
Entwisle et al. (1997) found very little evidence of school contextual
effects in the BSS data. Like Heyns, they used schools’ meal subsidy rate
as an indicator of school social context. To capture the effect of school
social context, they computed partial correlations, net of family SES,
between their contextual indicator and achievement growth for reading
and math during each of the 10 periods (over 5 years) in their survey.
These analyses revealed only one instance (out of 10 possible instances)
of a contextual school effect during the school year. The authors con-
cluded that school-year achievement gains were independent of the
Socioeconomic Context and Racial Composition 1349
socioeconomic composition of schools (Entwisle et al.). Paradoxically,
regarding the effects of school contexts, the authors found a cross-season
effect of school meal subsidy rate. For reading growth, higher school
meal subsidy rates were more consistently related to slower summer sea-
son reading achievement growth than the neighborhood poverty rate.12
Regarding neighborhood context, Entwisle et al. (1997) found that
neighborhood median income was positively related to reading achieve-
ment growth during the summer season, net of students’ family SES.
Similarly, neighborhood family poverty rates were negatively related to
achievement growth during the summer season. These associations held
for both factors in two of the three summers analyzed. Entwisle et al. con-
cluded that neighborhood social context exerted a consistent effect on
summer-season learning growth. Neighborhood context, however, was
judged not salient during the school season (Entwisle et al.). Data were
not available in the BSS to examine the relationship between neighbor-
hood context and achievement at school entry.
Racial Composition and Early Childhood Learning
The race/ethnic composition of neighborhoods and schools may affect
achievement through several different causal pathways, and social theo-
rists continue to debate the validity and strength of these pathways.
Perhaps the simplest reason that settings with large proportions of mem-
bers from minority race/ethnic groups can affect achievement is through
the relationship between race/ethnic composition and poverty. The con-
nection between segregation and the concentration of poverty is well
established (see Massey & Fischer, 2000). If neighborhoods or schools
with large proportions of poor (low-SES) residents and attendees slow
achievement growth, then it follows, given the connection between seg-
regation and poverty, that researchers will find connections between the
proportion of minority residents in a setting and achievement.
Segregation may directly affect the availability of resources for learn-
ing. For example, as recently as the 1980s, pupil-teacher ratios were sub-
stantially higher in schools primarily attended by African American
students in the 17 states that had once had de facto systems of school seg-
regation (see Boozer, Krueger, Wolkon, Haltiwanger, & Loury, 1992).
Although there has been an apparent convergence in the relative avail-
ability of such basic learning resources to Black and White students, evi-
dence suggests that this convergence does not extend to more
contemporary needs such as the availability of computers in classrooms
(Boozer et al.). However, resource measures account for only a small pro-
portion of variation in school quality (Rivkin, 2000). Thus, school com-
1350 Teachers College Record
parisons that use standard school-quality measures may mask important
differences in the quality of schools attended by White and non-White
students. This distinction is important because Black students perform
better on achievement tests when they attend schools deemed higher
quality based on their value-added effects for White students (Rivkin).13.
Race/ethnic composition may also affect achievement outcomes
through peer effects. Using fixed-effects models to control for school
quality, Hanushek, Kain, and Rivkin (2002) found that the proportion of
Black students in a school was negatively related to achievement test
scores for Black students but not for White and Hispanic students.
Looking at test scores for elementary school students, Hoxby (2000)
found that classroom proportion Black had the largest negative relation-
ship to reading scores for Black students, although it also depressed
scores for Hispanic and White students. Similarly, classroom proportion
Hispanic was negatively associated with reading scores for Hispanic stu-
dents and had a weaker negative association with reading scores for
White students. Taken together, these findings suggest that increases in
school and classroom proportions of students from specific minority
groups exert the strongest effects on students from within these minority
groups.
LIMITATIONS TO CONSIDERATION OF CONTEXT AND
COMPOSITION IN SEASONAL STUDIES
Despite the instances noted above, seasonal researchers have not fully
taken into account the relationships among socioeconomic context,
race/ethnic composition, and achievement inequality. For the most part,
seasonal researchers have forgone comprehensive inquiries into this area
because of limitations in the scope of data available to them. In addition,
limitations inherent in the analytical tools within statistical software pack-
ages have, until recently, prevented researchers from simultaneously
modeling students’ achievement growth trajectories while taking account
of extrafamilial context and race/ethnic composition. Thus, although
seasonal researchers have demonstrated a keen awareness of the poten-
tial contributions of neighborhood and school context, they have not
made context a central focus of their research agendas.
This article addresses this shortcoming in the extant literature through
use of a unique data set consisting of extensive socioeconomic and
race/ethnic measures from the 2000 Census and the ECLS-K, and
employment of an advanced statistical technique for analyzing the data.
Through this combination of data and analytical technique, we were able
to address several questions previously unaddressed by seasonal
Socioeconomic Context and Racial Composition 1351
researchers. The extensive set of precise measures in the census and
ECLS-K databases meant that the preliminary part of our research pro-
ject could accurately assess the contributions of family-level factors to
reading achievement inequality. The main stage of our project assessed
the analytically distinct contributions of social context and race/ethnic
composition to reading achievement inequality. We wanted to know what
our measures of context and composition could tell us about when and
where achievement inequality accrued between early childhood and the
end of first grade. Were there specific seasons when context was particu-
larly salient for reading achievement? Was neighborhood context most
salient during nonschool periods? Was school context most salient dur-
ing the school year? Was social context or race/ethnic composition more
strongly associated with reading achievement? Finally, did accounting for
context change our appraisal of the relationship between family factors
and achievement?
METHOD
DATA AND ANALYTIC SAMPLE
The sample for our analysis includes 4,180 students, all of whom were
attending one of 290 schools and living in one of 700 neighborhoods dur-
ing the period of our study, which spanned from the beginning of kinder-
garten until the end of first grade. Data on student test scores,
demographic characteristics, and family background came from the
ECLS-K, which was administered by the National Center for Educational
Statistics (NCES, 2002). The ECLS-K provides nationally representative
data for U.S. students who began kindergarten in fall 1998 and for sub-
sequent time points (for this cohort) through fifth grade. The most
intensive sampling took place during the kindergarten and first-grade
years. Data collected during the fall of first grade (hereafter FFG [fall first
grade]) included a survey supplement aimed at allowing researchers to
“measure the extent of summer learning loss and the factors that con-
tribute to such loss and to better disentangle school and home effects on
children’s learning” (NCES, 2002, p. 1-1). In the fall of 1999, NCES
administered achievement test batteries to all students in the kinder-
garten cohort who attended a random subsample of 30% of schools from
the base year survey. A total of 27% of kindergarten cohort students
attended the schools included in this subsample. Because NCES ran-
domly sampled schools rather than students for the FFG data collection,
this subsample includes sufficiently sized clusters of students within
schools for analysis of school effects. Our sample includes an average of
1352 Teachers College Record
14 students per school. The FFG sample served as the foundation for our
analytic sample. Our primary change to the FFG sample was to eliminate
1,060 students who changed schools or neighborhoods during the period
of this study. An additional 330 students were eliminated because they
had no test scores or parent reports available.14
To measure the social and race/ethnic characteristics of neighbor-
hoods, we drew data from the 2000 Census small area files. This data
source, comprising answers to questions in the “long form” of the 2000
decennial census, provides a rich assortment of measures concerning the
demographic and socioeconomic characteristics of neighborhoods.
Because of the inclusive sweep of long-form data collection, these data
are collected with less measurement error than the small-area microdata
collected between decennial censuses. Collection of the long-form data,
which pertain to neighborhood characteristics during 1999, coincided
with the kindergarten and first-grade years of the ECLS-K survey. We
linked the census data to the ECLS-K sample using the zip code of each
student’s home address. When a student’s zip code was not available, we
linked census measures pertaining to the zip code area of the student’s
school to best approximate the student’s neighborhood environment.
MEASURES
Reading Achievement
To measure reading achievement, we relied on information from one-on-
one child assessments conducted with the sampled children during the
fall of 1998, the spring of 1999, the fall of 1999, and the spring of 2000.
These assessments included cognitive, psychomotor, and physical compo-
nents. The reading assessments included questions designed to measure
basic reading skills (i.e., print familiarity, letter recognition, beginning
and ending sounds, rhyming sounds, word recognition), vocabulary
(receptive vocabulary), and reading comprehension skills (i.e., listening
comprehension, words in context). Comprehension items were targeted
to measure skills in initial understanding, interpretation, personal reflec-
tion, and critical stance. The ECLS-K database provides achievement out-
comes expressed as both scale scores and criterion-referenced measures
of students’ skills. We used the scale score measures—derived using an
item response theory (IRT) model—to model achievement growth.
Student-Level Characteristics
To construct the student-level measures for this study, we relied on
Socioeconomic Context and Racial Composition 1353
responses from the questionnaires administered to parents of ECLS-K
students during the fall of 1998 and spring of 1999 base-year parent sur-
veys. When responses were entirely missing from the base year, we
imputed them from the first-grade parent surveys, preferring responses
from the FFG survey and then moving to the spring of first-grade
responses when necessary.
Family SES. We used the measure of family SES computed by NCES as
an average of component variables indicating the guardian parents’ lev-
els of education, occupational statuses, and total household income
(NCES, 2002). Burkam et al. (2004) noted nonlinearities within the
ECLS-K data in the relationship between family SES and summer achieve-
ment, and in preliminary analyses, this pattern was clear to us as well. For
this reason, we employed the categorical (quintile) measures of SES con-
structed by NCES—computed from the original continuous measure.
Rather than computing quintiles within our analytic sample, we pre-
served the nationally representative character of the NCES quintiles.
Thus, because low-SES students were more likely to leave the ECLS-K sur-
vey, the low-SES student category constitutes less than 20% of our sam-
ple, whereas the high-SES category constitutes more than 20% (see Table
A1).
Race/ethnicity. Our race/ethnicity indicators were constructed from par-
ent-reported race/ethnicity information, which included the following
eight categories: White non-Hispanic, Black non-Hispanic, Hispanic,
Asian, Pacific Islander, American Indian, Alaska Native, and multiracial.
We collapsed categories to classify students into five categories: African
American, Hispanic, Asian-Pacific Islander, Native American (including
Alaska natives), and White. Students listed as multiracial were assigned to
the race of their mother.
Additional covariates. To control for students’ family structure, we used
a dummy variable to distinguish between two-biological-parent families
and all others,15 and a continuous variable to account for their number of
siblings. To account for school readiness, we included a measure of stu-
dents’ age (in months) at the beginning of school during the fall of 1998.
Because 4% of students were not beginning school for the first time in
fall 1998, we included a dummy variable that flagged these students who
were repeating kindergarten.
Measures of Context and Composition
We assumed that neighborhood and school contextual characteristics
remained stable during the period of the study. At the neighborhood
level, accounting for changing neighborhood characteristics would have
1354 Teachers College Record
required moving to much less reliable data than the Census 2000 data.
Our examination of school-level data indicated that in fact school char-
acteristics changed very little during kindergarten and first grade. For
these reasons, we feel confident that our contextual measures accurately
represent those neighborhoods and schools inhabited by students during
the course of this study.
Our measures of school context are aggregate, school-average mea-
sures that reflect the SES and race/ethnicity of individual students within
the ECLS-K sample. Our measures of neighborhood context come
directly from neighborhood averages computed by the Bureau of the
Census from responses to the 2000 decennial census long-form surveys.
Because survey respondents were asked to answer questions regarding
their statuses during 1999, our neighborhood measures most accurately
indicate the neighborhood context of students’ families during this year.
The overlap between the timing of the Census 2000 survey and the ECLS-
K study is fortuitous because 1999 was the year during which students
attended the second half of kindergarten, had their summer break, and
attended the first half of first grade.
To facilitate comparisons across neighborhoods and schools, we coded
separate contextual measures using identical procedures. Because the
2000 Census does not provide a detailed occupational scale at the zip
code level,16 we relied on income and education components to construct
our measures of neighborhood and school social context. We began by
determining the median income (in dollars) for each neighborhood and
school in our study. After computing the natural log of each unit’s
median income, we converted these figures to zscores. Next, we ascer-
tained the mean years of education for adults in each neighborhood and
school. Within neighborhoods, we computed the mean years of educa-
tion for neighborhood residents from categorical attainment data for all
male and female adults over the age of 25.18 Within schools, we relied on
parent reports and computed the mean years of education based on
available categorical educational attainment measures for each child’s
parents (or parent)17 and then converted these means to zscores. Next,
we computed continuous measures of neighborhood and school SES as
the arithmetic averages of the two component zscores. Preliminary analy-
ses using the continuous social context measures yielded two fundamen-
tal insights: (a) The relationship between social context and achievement
was not linear, and (b) the strongest relationships between social context
and achievement were located at the tails of the socioeconomic context
distribution. Thus, using the continuous social context measures, we
divided the 700 neighborhoods and 290 schools into equally sized socio-
economic quintiles. Because contextual effects were concentrated in the
Socioeconomic Context and Racial Composition 1355
highest and lowest socioeconomic categories, we collapsed the middle
three categories into one for the regression analysis.19
To account for the race/ethnic composition of neighborhoods and
schools, we again constructed identical measures for the two contexts. We
summed the numbers of residents from all minority groups within neigh-
borhoods, and the numbers of students from all minority groups within
schools, and divided these figures by the unit populations. In essence,
these measures captured the proportions of residents and students other
than non-Hispanic Whites.20
ANALYTICAL STRATEGY
The main methodological innovations in this study are the linking of
2000 Census data to indicate the socioeconomic character of neighbor-
hoods (see the preceding section), and the application of a third model-
ing level to measure the relationships between neighborhood and school
context, and student achievement. The modeling strategy used for this
study is quite similar to that used in other studies that have assessed
achievement growth for ECLS-K students over the first 2 years of elemen-
tary school (see Downey et al., 2004, and Reardon, 2003). In the termi-
nology of hierarchical linear modeling (HLM), the models employed in
this study are random intercept models (Raudenbush & Bryk, 2002). In
contrast to fixed-effects modeling strategies, the random coefficients
approach facilitates explaining variation in the outcome across units. We
employed that option in our models to explain variation in achievement
across two sets of contextual units—neighborhoods and schools. Before
discussing our modeling strategy for assessing the relationship between
context and achievement, we introduce the functions of level 1 and level
2 in our three-level growth models.
The Level 1 Model
Level 1 is a time-based model that employs repeated within-student obser-
vations to accomplish two main objectives. This level partitions achieve-
ment during the study period into a school-entry (intercept) parameter
and three growth parameters for subsequent seasons. The level 1 model
accommodates substantial season-to-season differences in reading
achievement growth by separately computing growth rates for kinder-
garten, summer, and first grade. Unique season-specific growth parame-
ters represent growth rates for each of these three periods. A seasonal
time variable activates each seasonal growth parameter, indicating the
number of months that each individual student had spent in the corre-
1356 Teachers College Record
sponding season, as of the date of each test administration. To account
for four separate test administrations, the level 1 model contains a sepa-
rate observation for each date at which a student was tested.21 Averages
for students’ time spent in each season are presented in panel 3 of Table
1. These measures account for temporal misalignments between the
school calendar and test administration dates. For a detailed description
of time accounting within the level 1 model, please see the methodolog-
ical appendix.

The Level 2 Model
The level 2 model resembles a traditional sociodemographic model of an
educational outcome and has two primary, interrelated functions. For
one, it accurately measures the multivariate associations among family
SES, student race/ethnicity, and reading achievement. Equally as impor-
tant, it computes unit-average (neighborhood or school) estimates of
achievement at school entry and during the three subsequent seasons.
This second objective requires identical22 level 2 models for each of the
four periods during which we estimated growth parameters. Within each
period, the intercept represents unit-average achievement level (at
school entry) or unit-average achievement growth (during kindergarten,
summer, and first grade). Parameter estimates for the social background
and demographic variables capture the associations between these vari-
ables and achievement during each specified period. Thus, our models
separately estimate unit-average achievement and covariate effects dur-
ing each study period. For a more detailed description of the level 2
model, please see the methodological appendix.
The Level 3 Model
The level 3 model accounts for the extent of achievement variability
across neighborhoods and schools, net of the student-level covariates pre-
sent in level 2. The model accomplishes this objective by including ran-
dom parameters for each level 2 intercept, each of which captures the
extent to which neighborhoods and schools departed from the unit-aver-
age achievement estimates computed in the level 2 portion of the model.
The presence of these unit-specific random parameters at level 3 (a)
accounted for the clustered nature of data within specific neighborhoods
and schools, (b) allowed for an accurate decomposition of variance
between the individual (level 2) and contextual (level 3) portions of the
overall model, and (c) reduced the possibility of bias in our parameter
estimates at both levels. Model 1 is a simple model that includes only the
random parameters—and no predictors—at level 3. Our subsequent
level 3 models represent variability in the level 2 intercepts as a function
of the socioeconomic context and race/ethnic composition of neighbor-
hoods and schools. Thus, Models 2–4 introduce contextual SES and
race/ethnic composition measures and assess the sizes of fixed effects
associated with these measures. Because of the careful partitioning of
variance into appropriate levels of analysis, these models produce accu-
rate estimates of the relationship between contextual measures and
1358 Teachers College Record
achievement. For a more detailed description of the level 3 model, please
see the methodological appendix.
FOUR EXPLANATORY MODELS
Preliminary Models: Unconditional, SES Only, and Race/Ethnicity Only
We began by computing an unconditional three-level model with no pre-
dictors other than the seasonal time variables at level 1. This model
allowed us to calculate a school-year average achievement growth rate
while making the necessary corrections for test-scheduling misalign-
ments. The seasonal averages from our unconditional model are pre-
sented in row 1 of Table 1. Next, we computed a three-level SES-only
model that included only the seasonal time measures and the four fam-
ily-SES quintile dummy variables. As in all subsequent models, the mid-
dle-SES quintile served as the reference categor y. Without exploring
causes, this model demonstrates the full extent of socioeconomic
achievement inequality during each of the four periods of our study, for
students nested within schools.23 The results from this model are pre-
sented in rows 2–6 of Table 1. The final preliminary model was a three-
level race/ethnicity-only model that included the seasonal time variables
and four categorical race/ethnic dummy variables. As in all subsequent
models, White race/ethnicity served as the excluded categor y. Results
from this model depict how race/ethnic achievement inequality looks
before accounting for socioeconomic status and demographic factors.
The results from this model are included in rows 7–11 of Table 1.
Model 1: Sociodemographic Model
Model 1 includes our full set of sociodemographic variables: the family
SES and race/ethnicity dummy variables (see preceding text); two family
structure measures (biological two-parent family and number of sib-
lings); two demographic measures indicating the child’s gender and age
at the beginning of school in fall 1998; and a final measure indicating
whether the child was repeating kindergarten as of fall 1998. This model
facilitates examining socioeconomic inequality in reading achievement
net of family factors that correlate with SES. In addition, race/ethnic
achievement inequality can be observed net of socioeconomic and fam-
ily factors that often correlate with race/ethnicity. Because level 1 of the
model estimates an intercept and separate growth parameters for each
of the three subsequent seasons, the four subsections of Model 1
portray how the relationship between sociodemographic factors and
Socioeconomic Context and Racial Composition 1359
achievement differs over the four periods included in this study.
Although Model 1 did not include contextual measures, it did include
random parameters that captured unit-to-unit variations among neigh-
borhood and school contexts. Separate versions of Model 1 were esti-
mated for students nested within neighborhoods and schools, and we
present these models in column 1 of Tables 2 and 3.
Model 2: Race/Ethnic Composition
Model 2 adds the measure for proportion minority to the full vector of
sociodemographic measures included in Model 1. To control for partici-
pation in academic programs that may be correlated with school or
neighborhood race/ethnic composition, Model 2 also includes a mea-
sure indicating full-day kindergarten and a measure indicating whether
the student attended an academic summer school.24 The students-within-
neighborhoods model (Table 2) differs from the students-within-schools
model (Table 3) because the full-day kindergarten measure is entered at
the student level (level 2) rather than the contextual level (level 3).
Model 2 facilitates a clear appraisal of the association between
race/ethnic composition and achievement before accounting for the
relationship between social context and achievement. Separate versions
of Model 2 were estimated for students within neighborhoods and
schools, and these models are presented in column 2 of Table 2 and
Table 3.
Model 3: Social Context
Model 3 adds measures for low- and high-SES contexts to the full vector
of sociodemographic measures included in Model 1 and the program
participation measures included in Model 2. This model assesses not only
the disadvantages associated with low-SES neighborhoods and schools
but also the advantages associated with high-SES contexts. Separate ver-
sions of Model 3 for students within neighborhoods and schools are pre-
sented in column 3 of Tables 2 and 3.
Model 4: Social Context and Race/ethnic Composition
Model 4 is the full model, which adds the measure of race/ethnic com-
position—included in Model 2—to the social context measures included
in Model 3. This model effectively assesses the relative strength of social
context and race/ethnic composition as influences on achievement
inequality across seasons. Model 4 is a barometer for determining

whether significant relationships observed in Models 2 and 3 persist
when considering social context and race/ethnic composition together
in the same model.
INTERPRETING COEFFICIENTS IN THREE-LEVEL GROWTH MODELS
We employed two metrics for interpreting results from the growth mod-
els. When considering reading achievement inequality at school entry, we
relied on standard deviations in scale score points for the test adminis-
tered in fall of kindergarten. As indicated in Table A1, this standard devi-
ation was 9.074. When considering growth rates in subsequent seasons,
we interpreted significant coefficients and gaps (between coefficients) in
relationship to an average monthly rate of achievement growth during
the school year. Averaging the school-year growth rates from the uncon-
ditional model (Table 1, row 1) produced a monthly school-year growth
average of 2.1 points per month. We found it helpful to evaluate seasonal
gaps in reading growth in relationship to this average. The regression
models described previously easily facilitate such calculations and com-
parisons. Because 1 month is the unit of time at level 1 (in all models),
all seasonal growth slopes (presented at the top of each seasonal sub-
model) represent monthly growth rates, and all growth coefficients (asso-
ciated with the model covariates) represent monthly changes to the
growth slopes.
RESULTS
FAMILY SES, RACE/ETHNICITY, AND READING ACHIEVEMENT AT
SCHOOL ENTRY
Nowhere was the relationship between family SES and reading achieve-
ment more apparent than at school entry. Students from low-SES families
entered school roughly one standard deviation below their counterparts
from high-SES families. The initial status portion of Model 1 (Table 2)
shows the significant relationship between family SES and achievement at
school entry. Using the high- and low-SES coefficients from Model 1, we
computed a social achievement gap of 0.98 standard deviation units,
(5.555 – (-3.339) / 9.074.
African American students did not begin school behind White students
from similar family backgrounds. When controlling for family SES, as we
did in this and all subsequent models, we found no evidence that African
American race/ethnicity was associated with children’s reading achieve-
ment at school entry.25 The absence of a Black-White gap in reading
Socioeconomic Context and Racial Composition 1367
achievement at school entry, net of socioeconomic and family character-
istics, is consistent with other research that has explored Black-White
achievement differences among students in the ECLS-K (see Fryer &
Levitt, 2004). Hispanic race/ethnicity, however, was associated with a
somewhat lower level of reading achievement at school entry. Using the
Hispanic coefficient from Model 1, Table 2 (-1.326), the Hispanic-White
gap amounted to -0.15 standard deviation units.26
CONTEXT, COMPOSITION, AND READING ACHIEVEMENT AT
SCHOOL ENTRY
After accounting for family-level differences in reading achievement, our
measures of neighborhood social context explained a substantial addi-
tional portion of variation in reading scores at school entry. Most notable
was the positive increment associated with residence in a high-SES neigh-
borhood. Using the coefficient for high-SES neighborhood in Model 3
(2.110), we computed a contextual advantage of 0.232 standard deviation
units for students growing up in high-SES neighborhoods. The contex-
tual disadvantage for students growing up in low-SES neighborhoods
amounted to a smaller figure of 0.10 standard deviation units.27One way
of interpreting the size of these effects is to compute a total contextual
achievement gap and compare it with the size of the social gap for family
SES (see preceding text). The contextual achievement gap totals 0.33
standard deviation units, 2.110 – (-0.906) / 9.074, roughly one third the
size of the social gap (0.98 SD units).
There was no apparent relationship between the proportion of resi-
dents from minority race/ethnic groups in neighborhoods and reading
achievement at school entry. Model 2 presented the strongest test of the
hypothesis that such a relationship existed, and the coefficient for pro-
portion minority (-0.235; SE = 0.705) did not approach statistical signifi-
cance. Our findings are consistent with the neighborhood study of early
childhood learning by Brooks-Gunn et al. (1993), who found larger
effect sizes for affluent than poor neighborhoods and no additional dele-
terious effects for largely minority neighborhoods.
FAMILY SES, RACE/ETHNICITY AND SUMMER SEASON ACHIEVE-
MENT
Family SES was clearly associated with reading achievement growth dur-
ing the summer season. On average, students from middle-SES families
did not grow in reading achievement during this period; they simply
maintained their end-of-kindergarten reading level until the beginning
1368 Teachers College Record
of first grade. In contrast, students from high-SES families continued to
grow, whereas students from low-SES families lost ground. The third sec-
tion of Model 1 (Table 2) presents coefficients for summer reading
achievement growth. The family-SES coefficients for the summer growth
slope indicate that high-SES students grew 0.25 points per month,
whereas low-SES students lost 0.26 points per month of reading achieve-
ment. To interpret these results, we computed a social achievement gap
between high- and low-SES students and compared it with our average
school year reading growth rate of 2.1 points per month (see preceding
text). The social achievement gap of 0.51 points per month, 0.249 – (-
0.263), summed to 1.35 points over the course of an average summer (2.6
months), resulting in a noticeable difference of 0.64 months of school-
year growth between low- and high-SES students. In contrast, we found
that lower middle SES students did not differ from the static growth tra-
jectory of middle-SES students. Upper middle SES students appeared to
grow at a slightly faster pace (0.18 points per month), but their coeffi-
cient was not statistically significant. Thus, we conclude that differences
in summer-season achievement were concentrated among students with
families whose SES differed significantly from that of middle-SES stu-
dents, a finding consonant with prior summer research using the ECLS-
K (see Burkam et al., 2004).
Race/ethnicity was related to summer reading achievement growth in
an unexpected way. Controlling for a host of sociodemographic factors,
as in all the explanatory models, we found that African American stu-
dents learned at a faster pace than (similar) White students during the
summer. Model 1 (Table 2) indicates a monthly summer learning growth
increment of 0.249 points for African American students relative to
White students. The size of this coefficient is slightly larger than the neg-
ative monthly Black-White gap of roughly 0.2 points that persisted
throughout kindergarten and first grade. However, over the course of an
average summer, this monthly increment summed to 0.31 months of
school-year reading growth, less than one quarter the size of the Black-
White gap that accumulated during the school year (see the section titled
“Family SES, Race/Ethnicity, and School-Year Achievement”).
CONTEXT, COMPOSITION, AND SUMMER READING ACHIEVEMENT
Neighborhood social context was salient during the summer season,
whereas neighborhood race/ethnic composition was not. The associa-
tion between social context and achievement was concentrated in high-
SES neighborhoods. As indicated in the summer portion of Model 3
(Table 2), students residing in high-SES neighborhoods grew in reading
Socioeconomic Context and Racial Composition 1369
achievement by an additional 0.272 points per month (relative to middle-
SES students). Over the course of an average summer, this monthly incre-
ment summed to 0.34 months of school-year reading growth. The
coefficient for low-SES neighborhoods was negative, and the coefficient
for the proportion minority residents was positive, but neither
approached statistical significance. Thus, high-SES neighborhoods were
the only context significantly related to summer season achievement
growth.
Neighborhood social context was linked to the summer season reading
growth patterns for students from high-SES families. Comparing across
Models 1 and 3 (Table 2), we found that the coefficient for high SES fell
in size from 0.249 to 0.200 points per month, thereby dropping below the
level of statistical significance. Thus, accounting for social context
explained one quarter of the summer social advantage for students in
high-SES families, which indicates that some of the summer advantage
attributed to high-SES families in Model 1 was a consequence of the
neighborhoods in which these families tended to live. Looking across
Models 3 and 4, we also noted that, when accounting for both neighbor-
hood SES and proportion minority, the negative coefficient for low-SES
family dropped below the statistical significance level of p< 0.05.
However, the drop in coefficient size was slight; thus, accounting for
neighborhood social context does not change our finding that, regard-
less of context, students from low-SES families tended to lose ground in
reading achievement during the summer. There was, however, some evi-
dence that accounting for neighborhood proportion minority explained
a portion of the previously noted summer advantage for African
American students. Comparing across Models 3 and 4, we found that
accounting for neighborhood proportion minority reduced the African
American coefficient size from 0.272 to 0.225, thus pushing it below the
threshold for statistical significance. Although positive, the coefficients
for proportion minority in Models 2 and 4 were not statistically signifi-
cant. Thus we simply conclude that neighborhood proportion minority
was not associated with slower rates of summer reading growth for
African American students, or students in general.
FAMILY SES, RACE/ETHNICITY, AND SCHOOL-YEAR ACHIEVEMENT
We found strong evidence that low-SES students grew in reading achieve-
ment at a slower pace than students from all other SES groups during
first grade, and weaker evidence for the same trend during kindergarten.
Coefficients from Model 1, Table 3, indicate that low-SES students’ read-
ing achievement grew 0.221 points per month slower than middle-SES
1370 Teachers College Record
students in first grade. In kindergarten, low-SES students grew 0.113
points per month slower than middle-SES students. Over the course of an
average school year, the monthly decrement in first-grade growth cumu-
lated to approximately 1 month, (9.4 * 0.221) / 2.1, and the kinder-
garten decrement cumulated to approximately half a month, (9.4 *
0.113) / 2.1, of school-year reading growth.
The school year was also a period of dispersion in reading achievement
growth by race/ethnicity, with African American students growing at a
substantially slower pace than similar White students in both school years.
The size of the monthly Black-White gap was large and roughly equal in
both school years. Model 1 of Table 3 indicates that Black students grew
0.206 points slower than comparable White students in kindergarten,
and 0.209 points slower in first grade. Over the course of the two school
years, these monthly gaps summed to 3.9 points, or almost 1.9 months of
school year reading growth. The Hispanic-White gap in school-year
growth was smaller than the Black-White gap and not as consistent. The
monthly Hispanic-White gap in kindergarten (0.126 points per month)
summed to a modest difference of 1.18 points over the school year, or just
over half a month of school-year reading growth. In first grade, however,
only the students-within-neighborhoods models (Table 2) identified a sig-
nificant Hispanic-White gap (0.1 points per month). We conclude that
Hispanic-White gaps were present but considerably smaller than Black-
White gaps in both kindergarten and first grade. Once school began,
African American students were quickly falling behind White students.
CONTEXT, COMPOSITION, AND SCHOOL-YEAR READING
ACHIEVEMENT
School social context exerted a strong influence on reading achievement
during kindergarten and first grade. However, in kindergarten, the rela-
tionship between school social context and reading achievement
reflected an unexpected pattern. Both low-SES and high-SES contexts
were associated with slower rates of achievement growth during kinder-
garten. Thus, although there was a social gap in reading growth during
kindergarten, there was not a contextual gap. To point, Model 4 of Table
3 indicates that, compared with students in middle-SES schools, students
in low-SES schools grew 0.163 points per month slower, and students in
high-SES schools grew 0.188 points per month slower.
The relationship between school social context and reading growth
during first grade took on a pattern similar to that noted for neighbor-
hood social context at school entry and during the summer. There was
an advantage associated with attending high-SES schools, relative to
Socioeconomic Context and Racial Composition 1371
middle-SES schools, whereas there was no significant disadvantage asso-
ciated with attending a low-SES school. This advantage is indicated by the
monthly coefficient for high-SES schools of 0.245 in Model 3, and 0.203
for high-SES schools in Model 4 (Table 3). The coefficient for low-SES
schools in Model 3 (-0.144) approached statistical significance. However,
once we accounted for school proportion minority in Model 4, the coef-
ficient for low-SES schools sank to 0, indicating that the slower growth
rates observed in some low-SES schools were more strongly associated
with the proportion of minority students than school social context.
The proportion of minority students was not associated with kinder-
garten reading growth but was strongly associated with first-grade reading
growth. The coefficient for proportion minority in first grade (-0.410)
indicates that for each standard deviation (0.36)28 increase in the propor-
tion of minority students in a school, the average reading growth rate for
students in the school fell by 0.15 points per month, 0.36 * (-0.41). In
addition to its relationship to average school achievement growth, school
percent minority was related to the first-grade growth rates of African
American students. The span of Models 1–4 illustrates that as we
accounted for school proportion minority in Models 2 and 4, the Model
1 coefficient for African American students shrank to half its original
size, from - 0.209 in Model 1 to - 0.103 in Model 2, and likewise to -0.105
in Model 4. In both instances, this change in coefficient size rendered the
smaller coefficient for African American students nonsignificant. We did
not uncover a similar pattern in the kindergarten findings. Nevertheless,
our first-grade finding indicates that school race/ethnic composition was
strongly linked to reading achievement, especially for African American
students. Moreover, this finding suggests that a substantial portion of the
first-grade reading disadvantage for Black students was a consequence of
location in schools with large concentrations of minority students, rather
than rearing in African American families.
DISCUSSION
FAMILY, RACE/ETHNICITY, AND ACHIEVEMENT ACROSS SEASONS
Family SES was most striking in its relationship to achievement at school
entry. As noted previously for Model 1 of the students-within-neighbor-
hoods analysis, students from high- and low-SES families entered school
almost a standard deviation from each other in levels of reading achieve-
ment. Similar dispersion was present in Model 1 of the students-within-
schools models. With controls for family background, both of these
models reflect the compositional effects of preschools and other commu-
1372 Teachers College Record
nity institutions and resources that are designed to enhance students
readiness for school. The students-within-schools model, rather than
implicating schools as causes of inequality, provides a more general por-
trait of the inequalities that schools inherit from their neighborhood con-
texts. The vast majority of students attend neighborhood schools, and, as
a result, the makeup of the student body mirrors the socioeconomic,
racial, and ethnic makeup of the surrounding neighborhood (Panel on
High-Risk Youth, 1993). Relative to middle- and high schools, elementary
schools have tighter neighborhood-based attendance zones that are espe-
cially prone to school segregation by poverty, race, and ethnicity.
Therefore, our first model shows that schools are faced with substantial
inequalities at the beginning of the kindergarten year that are rooted in
the larger social contexts of the neighborhoods in which they are situated.
Our findings validate previous seasonal studies that have identified
social achievement gaps during the summer season; we also find cause
for concern with the slower pace of reading growth for low-SES children
during first grade. Because the school year lasted longer than 9 months,
whereas the summer break was less than 3 months, the implication of the
monthly first-grade achievement decrement for low-SES children was
substantial. Whereas the summer decrement of 0.26 points (Model 1,
Table 2) per month summed to 0.32 [(2.6 * 0.26) / 2.1] months of
school-year achievement growth, the monthly first-grade decrement of
0.21 points per month (Model 1, Table 3) summed to 0.94 [(9.4 * 0.21)
/ 2.1] months of school-year growth.
Our finding of a school-year disadvantage in reading growth for low-
SES students contradicts previous seasonal research by Entwisle and
Alexander (1997), who did not find significant dispersion of reading
achievement growth by family SES during elementary school. Our find-
ing is more consistent with Heyns’s (1978) view of school as a countervail-
ing, but not entirely compensatory, force in relationship to families.
However, in a pattern consistent with Entwisle and Alexander’s faucet
theory, lower middle SES and upper middle SES students’ school-year
growth rates did not differ significantly from those of middle-SES stu-
dents. Thus, it could be said that schooling helped to equalize achieve-
ment for the broad middle-SES population of students. Nevertheless, the
magnitude of the disadvantage for low-SES students—especially in first
grade—stands out as a significant problem, especially when considering
that these students entered school one third of a standard deviation
behind their middle-SES peers.
Our findings regarding race/ethnicity and achievement over the first 2
years of formal schooling are also cause for concern. Of particular inter-
est is our finding that race/ethnic inequalities in achievement emerged
Socioeconomic Context and Racial Composition 1373
almost entirely during the school year. The Black-White achievement gap
was large in kindergarten and first grade, yet African American students
grew at a faster pace than similar White students during the summer sea-
son. Hispanic students did not fall behind similar White students during
the summer season either, yet a Hispanic-White gap was clearly present in
kindergarten and, in the neighborhood models, in first grade. Moreover,
African American students entered school at achievement levels equal to
White students from similar social backgrounds, and Hispanic students
entered school only moderately behind similar White students. Our find-
ings, consistent with prior seasonal research, indicate that the school sea-
son is the main time period during which race/ethnic achievement gaps
widen.
The Seasonal Relevance of Neighborhood and School Context
Our modeling strategy facilitates a clear set of inferences concerning the
relative importance of neighborhood and school context for achieve-
ment at school entry and during the summer season. We treated neigh-
borhood context, rather than school context, as relevant to the
prekindergarten achievement reflected in test scores at school entry. For
the summer season, the possibility existed that schools could have influ-
enced summer season reading achievement. The strongest test of this
hypothesis is to evaluate the strength of association between school con-
text and summer achievement growth without controlling for neighbor-
hood context. This is exactly the test posed by our students-within-schools
model of summer reading growth (Table 3). As noted, none of the school
context measures reached statistical significance when predicting sum-
mer reading growth. Thus, we conclude that neighborhood context was
more relevant than school context to reading achievement during the
summer season, as well as during the preschool period. Our analysis did
not produce evidence of a cross-season interaction as noted by Entwisle
et al. (1997).
The weight of evidence from this study indicates that school context
was more strongly associated with school-year achievement growth than
neighborhood context. We drew this inference by comparing each of the
school-year contextual coefficients across the neighborhood and school
models for kindergarten and first grade. Inference from the two
instances in which coefficients did not match is fairly straightforward.
Low-SES schools were negatively associated with kindergarten reading
growth, whereas low-SES neighborhoods were not. High-SES schools
were positively associated with first-grade reading growth, whereas high-
SES neighborhoods were not. For each of these instances, we conclude
1374 Teachers College Record
that school context was more salient than neighborhood context. For
proportion minority during kindergarten and low-SES during first grade,
we found that neither school nor neighborhood context was significantly
associated with reading growth. Inference for the remaining two
instances is more difficult.
In first grade, neighborhood and school proportion minority were neg-
atively associated with overall reading growth. Comparing across neigh-
borhood (Table 2) and school models (Table 3) suggests that the
school-reading linkage was stronger than the neighborhood-reading link-
age because the coefficient for proportion minority was larger in the
school model (-0.410 vs. -0.314). The school-reading linkage also appears
stronger for African American students, as evidenced by comparing
across the neighborhood and school models. Accounting for school pro-
portion minority explained roughly half of the Black-White reading
growth gap (Model 1 to Model 2 of Table 3), and accounting for neigh-
borhood proportion minority explained one quarter of the Black-White
gap (Model 1 to Model 2 of Table 2). For Hispanic students, however, this
pattern was reversed. Accounting for neighborhood proportion minority
reduced the Hispanic-White gap of - 0.136 points per month to less than
half that size (Models 2–4 in Table 2). In the students-within-schools
models (Table 3), the Hispanic-White gap was not statistically significant
in any of the models. Thus we conclude that school context was more
salient for African American students and neighborhood context was
more salient for Hispanic students during first grade. Although, on the
whole, school race/ethnic composition appeared more salient than
neighborhood race/ethnic composition during the school year, we find
it entirely plausible that neighborhood proportion minority contributed
to slower rates of growth during first grade.
The final instance for the school-neighborhood comparison concerns
the relative salience of high-SES neighborhood and school contexts to
kindergarten reading growth. Because high-SES contexts were negatively
related to reading growth at the same magnitude, our findings indicate
that either or both contexts could have been causally related to kinder-
garten reading growth. Summarizing across each of the six school-year
comparisons of neighborhood and school contexts, we conclude that our
findings are consistent with the foundational hypothesis of seasonal
learning theory: When school is in session, it supersedes the influence of
other contexts. However, we cannot rule out the possibility that neighbor-
hood context remains salient during the school year, albeit to a lesser
extent than school context, or that neighborhood context continues in
importance for specific student groups (such as Hispanic students) dur-
ing the school year.
Socioeconomic Context and Racial Composition 1375
The Seasonal Relevance of Social Context and Race/Ethnic Composition
Our findings indicate that social context was relevant to achievement in
all seasons, whereas race/ethnic composition was only relevant during
the school year. The social contextual gap in achievement at school entr y
was substantial, and the clear pattern of advantage accruing to students
located in high-SES social contexts continued during the summer season
and first grade. Although we did not find a social contextual gap in read-
ing growth during kindergarten, the appearance of a gap between stu-
dents in low- and middle-SES schools still merits further attention to the
factors producing that gap. With the exception of this kindergarten find-
ing, our work is consonant with that of Brooks-Gunn et al. (1993), who
found that the positive benefits of socially advantaged neighborhoods
often outweighed the negative effects associated with poor neighbor-
hoods.
Regarding race/ethnic composition, our findings indicate that neigh-
borhood proportion minority was not salient for students’ reading
achievement in the period prior to school entry, during kindergarten, or
during the summer season, but it appeared important, especially for
Hispanic students, during first grade. School race/ethnic composition
was clearly associated with reading achievement growth during first
grade. Despite this strong relationship in first grade, however, school
minority composition was not related to reading growth during kinder-
garten. There is no conclusive way to reconcile these two findings. The
first-grade association could signal the beginning of a trend with a
strengthening relationship between school proportion minority and
achievement growth. This pattern would be consistent with the findings
of Hanushek et al. (2002), who found substantial school compositional
effects for middle school students, especially African American students.
Or, the association could be an aberration, with no such relationship
occurring in subsequent grades. More research based on students within
the ECLS-K is needed to draw conclusions about the consistency of this
relationship across later grades.
The Independent and Additive Nature of Contextual and Compositional Effects
Our analysis clearly demonstrates that social context and race/ethnic
composition were related to reading achievement in ways that go beyond
the contributions of family social background and race/ethnicity to
inequality. We construe these contextual effects as largely additive to fam-
ily-based differences in achievement. We note strong linkages between
family SES and social context, and between student race/ethnicity and
1376 Teachers College Record
school race/ethnic composition. Thus, for large proportions of low-SES,
lower middle-SES, African American, and Hispanic students in this study,
the combination of family origins and context constituted a double dis-
advantage, with respect to reading achievement, relative to higher SES
and White students. As noted, there were instances in which accounting
for context explained a portion of achievement inequality first noted at
the family level. Even in these instances, it is safe to say that context
tended to exacerbate persistent patterns of family-based inequality in
achievement.
POLICY IMPLICATIONS
Our findings complicate possible strategies for ameliorating achievement
inequality among young children and help to clarify the broader picture
of educational inequality in U.S. society. With some important exceptions
(e.g., Entwisle et al., 1997), much previous educational research has
tended to ignore neighborhoods as a key nonschool environment that
shapes children’s cognitive development. Our findings suggest that con-
temporary policy reforms aimed at equalizing achievement among stu-
dents from different social and racial/ethnic backgrounds may not
accomplish their aims unless they extend to addressing the vastly differ-
ent neighborhood conditions in which children are growing up and
learning.
In tandem with implementation and evaluation of the Gautreaux and
MTO residential mobility programs, substantial attention has been given
to the potential benefits of moving low-SES and African American fami-
lies to more affluent and integrated neighborhoods. Findings from eval-
uations of these programs seem to indicate that only moves to
substantially improved contexts boost achievement and educational out-
comes for students. Among students in the ECLS-K, we find scant inci-
dence of such moves, and thus, there is no way to evaluate their benefits
for students. However, using an additional set of slopes-as-outcomes
growth models,29 we have evaluated the benefits for low-SES and lower
middle SES students who were located in middle-SES neighborhoods and
schools. At school entry, we saw no advantage conferred on lower SES stu-
dents located in middle-SES neighborhoods. When examining the bene-
fits for lower SES students attending middle-SES schools, there was some
evidence that low-SES students grew faster in reading during first grade
when located in middle-SES schools, but there were so few low-SES stu-
dents (only 7% of all low-SES students) located in middle-SES schools
that the parameter estimates are unreliable. In summary, the narrow
scope of movement of families to contexts that did not match their own
Socioeconomic Context and Racial Composition 1377
SES makes it impossible to estimate the effects of moving socially disad-
vantaged students to more advantaged contexts. Our findings are consis-
tent with the conclusion, from mobility studies, that modest changes in
context do not stimulate significant differences in achievement.
Our findings also raise questions about the degree to which schools are
functioning as equalizers for low-SES and minority students. Although
our kindergarten findings were mixed, our first-grade findings point to a
clear achievement disadvantage for low-SES students relative to all their
peers, and a clear advantage for students attending high-SES schools.
Moreover, our findings from both years demonstrate a clear disadvantage
for African American students, and our first-grade findings show a disad-
vantage for students attending schools with large percentages of minor-
ity students. Each of these disadvantages reinforces patterns of
educational inequality that have been the focus of extensive policy
debate and intervention.
If policy makers seek to address inequality, they must look beyond sim-
ply improving high-poverty and segregated neighborhoods and schools
to replicating the advantages present in socially advantaged neighbor-
hoods and schools.
CONCLUSIONS
Because of differing perspectives on how one should interpret and mea-
sure contextual effects, the causal mechanisms and the actual magni-
tudes of these effects continue to be matters of scholarly debate
(Gamoran, 1992; Jencks & Mayer, 1990). We have taken several steps to
address methodological challenges to identifying contextual effects in
observational studies. We have accounted for many of the family back-
ground characteristics that may explain achievement differences across
contexts. After taking these factors into consideration and after modeling
the attributes of neighborhoods and schools at the proper level of aggre-
gation, we are confident that the observed relationships represent the
contextual effects of neighborhoods and schools above and beyond the
effects of family SES and other background characteristics. We see in our
analysis clear evidence that socially advantaged contexts support early
childhood learning. The possibility remains that families differ consider-
ably in their preferences for, and their abilities to benefit from, the con-
texts they inhabit. New research is needed to identify the conditions
under which contextual effects can generalize to families relocated
through residential mobility programs and school integration programs.
Our primary task in this article, however, has been to isolate contextual
from family effects.
1378 Teachers College Record
Looking beyond methodological challenges to identifying contextual
effects, we find theoretical and substantive reasons to believe that we have
accurately captured the contextual effects of neighborhoods and schools.
The idea that social structure affects an individual’s outcomes, indepen-
dent of his or her characteristics and background, is one that is funda-
mental to sociological investigations. Schooling, which affects each
student individually but is also a collective enterprise occurring within
classrooms, schools, and neighborhoods, is a prime example of this phe-
nomenon. Duncan and Raudenbush (2001) have stated that “research
on the organization of preschool and elementary school would lead into
exciting and as yet unexplored territory” (p. 368). However, to date,
models of educational outcomes and context have been confined mainly
to the secondary school years. Our work supports the alternate perspec-
tive, offered by Entwisle and Alexander (1999), which emphasizes that
the context in which children’s early development occurs is crucial to
understanding the trajectories that take young children to their adult
social positions. Our study of context, inequality, and educational out-
comes during the early elementary school years helps to address a rela-
tively large void in the literature. This study has extended previous
seasonal research using the ECLS-K by bringing into focus the dimen-
sions of social context and race/ethnic composition. We hope that our
fine-grained decomposition of the “when and where” of achievement
gaps can serve as a guiding complement to other research agendas that
seek to explain exactly “how” gaps emerge within each context and how
they can be ameliorated.

1. The long summer session is peculiar to the United States, a holdover from the
agrarian necessities for child labor during the 18th and 19th centuries (see Wiseman &
Baker, 2004).
2. The term faucet theory derives from the proposition that the school resource “faucet”
is turned on during the school year and turned off during the summer (Entwisle et al.,
1997).

3. In her regression analysis of achievement growth for seventh graders, the size of the
coefficient for parental education dropped by 40% when moving from the summer season
to school year analysis (Heyns, 1978, table 4.6, p. 72).
4. The number of people in a census tract varies from 1,500 to 8,000 people; the aver-
age size is approximately 4,000 people. Census zip code tabulation areas (ZCTAs) often
include more than one census tract, and thus they tend to exceed tracts in size and vary
more in size. On average, 8,600 individuals reside in a ZCTA; among all ZCTAs, the num-
ber of residents varies from 0 to 113,600. In the sample for this study, the number of resi-
dents in a ZCTA varied from 58 to 101,571, averaging 26,465 persons.
5. The Stanford-Binet IQ Test was the most commonly administered test of cognitive
ability at the time of this study. Form L-M, third edition, was used.
6. Using zip codes, Ainsworth matched neighborhood measures from the 1990 U.S.
Census to student data from the National Educational Longitudinal Study of 1988
(NELS:88).

8. The authors argued that equal grades meant higher achievement in suburban than
city schools.
9. Additionally, some students were located in schools outside the catchment areas for
their residences of origin prior to the beginning of the MTO program.
10. Heyns referred to these schools as low SES and high SES, but the distinction between
the two was based exclusively on whether the school had 45% or more of its students
enrolled in the free and reduced price lunch program. If the school met this criterion, it
was deemed low SES; all other schools were considered high SES.
11. Heyns used two low-income categories: (a) low-income students came from house-
holds with incomes between $4,000 and $7,999 per year, and (b) extremely low-income students
came from families with incomes of less than $4,000 per year (Heyns, 1978).
12. The school meal subsidy rate was negatively related to reading growth during each
of three summers considered, whereas the neighborhood poverty rate was negatively
related to reading growth during two of the three summers (Entwisle et al., 1997, table 3.8).
13. Rivkin computed value-added statistics for White students and used them as a mea-
sure of school quality for Black students attending the same schools.
14. See the methodological appendix for further details of the sample construction.
15. Preliminar y analyses indicated no substantial differences in the effects associated
with single- and alternative two-parent families; thus, we collapsed these two categories in
the final models.
16. At the zip code level of aggregation, the Bureau of the Census provides only a six-
category division of occupational sectors, each of which contains occupations with widely
varying statuses.
17. NCES categorized parents’ educational attainment according to nine categories.
Within two-parent families, attainment responses were sought, and frequently obtained,
from both parents. For two-parent cases, we converted each parent’s attainment category to
a continuous measure and computed the average to produce a measure of years of educa-
tion on a scale of 0 to 20 years. For one-parent cases, we simply used the continuous mea-
sure for the single parent.
18. The census provided attainment data, by gender, for 16 categories of attainment; we
converted each category to an appropriate continuous value before computing the mean
years of education within each neighborhood.
19. Alternate analyses (not included) using four categorical SES variables (and an
1380 Teachers College Record
excluded middle-SES category) did not produce any significant achievement differences
among neighborhoods and schools in the three middle-SES categories.
20. As with our individual-level measures, the Hispanic categor y comprised all
race/ethnic categories for Hispanics, including Hispanic Whites.
21. Our final models included 15,870 observations at level 1.
22. Two exceptions to the identical nature of our level 2 models were (a) the account-
ing for summer school attendance during the summer season, and (b) the accounting for
full-day kindergarten attendance during the kindergarten season. By necessity, these factors
were represented at different levels in the neighborhood and school models. Neither of
these factors was included in the school-entry and first-grade portions of our models.
23. Table 1 is based entirely on students-within-schools models, so it does not represent
the full extent of summer season inequality.

methodological appendix.
25. Even considering the race/ethnicity-only model—presented in rows 7–11 of Table
1—the reading disadvantage for African American students relative to White students was
fairly small: -1.370 / 9.074 = -0.15 standard deviation units.
26. The Hispanic-White disadvantage in the race/ethnicity only model was larger, -
2.278 / 9.074 = -0.25 standard deviation units.
27. This figure is based on the low-SES neighborhood coefficient (-0.906) from Model
3, which was divided by the standard deviation in test scores for the fall of kindergarten test
(9.074).
28. The mean proportion minority in schools was 0.413, with a standard deviation of
0.361; the mean proportion minority in neighborhoods was 0.338, with a standard deviation
of 0.303.

METHODOLOGICAL APPENDIX
ANALYTIC SAMPLE CONSTRUCTION
In keeping with other contextual studies, we removed students who
changed schools or neighborhoods during the study period. We began
with the full FFG subsample—5,470 students. We eliminated 940 students
because they changed schools between the beginning of kindergarten
and the end of first grade, and 130 students because they changed neigh-
borhoods between the fall of first grade and the spring of first grade.1
Next, to ensure a minimum level of achievement data for each student in
Socioeconomic Context and Racial Composition 1383
the analytic sample, we eliminated 130 students who did not have at least
one test score available. Finally we eliminated an additional 100 cases
from our analytic sample because they had no family background data
available from either year. Table A.1 presents descriptive statistics for the
full and analytic samples, and for movers excluded from the analytic sam-
ple. Results of t-tests and chi-square tests indicate the presence (or
absence) of differences between movers and students in the analytic sam-
ple. Movers tended to have slightly lower test scores, were more likely to
be from low-SES and non-traditional families, and were more likely to be
African American and Hispanic.
Because item nonresponse rates were low and data—when missing for
any background variable—tended to be missing for all background mea-
sures at once, we did not see a benefit to multiply imputing background
data. Rather, when background measures were missing from the kinder-
garten rounds of parental interviews, we imputed data from parallel
questions in the first-grade interviews. This process allowed us to pre-
serve many cases in the dataset that other wise would have been elimi-
nated.
Program Participation Measures
Our measures of program participation reflect seasonal researchers’
emphasis on the importance of exposure to schooling (Entwisle et al.,
1997; Heyns, 1978). This line of research has tended to focus on the
effectiveness of summer school programs for boosting achievement and
attenuating socially induced achievement inequalities (Cooper et al.,
1996), but it has also considered school-year enhancements such as full-
day kindergarten (Lee, Burkam, Ready, Honigman, & Meisels, 2006).
Our analysis includes summer school and full-day kindergarten mea-
sures. We included these measures in the analysis because availability of
these programs may vary across contexts, and we wanted to assess contex-
tual effects net of program participation.
Our program participation measures were designed to capture
increased academic training. With regard to summer school, researchers
using ECLS-K data have tended to find negative but non-significant
effects of summer school enrollment (Burkam et al., 2004; Downey et al.,
2004). These results may reflect issues of selection into summer school
programs and were obtained without controls for the academic content
of the programs. Our measure of academic summer school captured
exposure to academic material during the summer season, as reported by
parents during the FFG survey. When parents indicated that their chil-
dren had attended a summer school program that included both reading
1384 Teachers College Record
and math instruction, we coded our dichotomous measure as one; for all
other cases, we coded this measure as zero. With regard to the school
year, researchers using ECLS-K data have found positive effects of full-day
kindergarten programs (Lee et al., 2006). We coded a dichotomous mea-
sure as one when a school provided full-day kindergarten classes to a
majority of its students, as indicated by both the ECLS-K field manage-
ment data report and individual student reports.2
THREE-LEVEL MODELING STRATEGY
The Level-1 Model
Accurately estimating seasonal growth parameters for kindergarten, sum-
mer, and first grade requires knowing the exact durations of time that
students spent in each season. Because students were not tested on the
first and last days of the school year, it was necessary to correct for mis-
alignments between the school calendar and testing schedule, which
required precisely measuring the duration of time between school begin
(and end) dates and test administration dates. Our seasonal time vari-
ables accurately apportion time spent in each season to the tenth of a
month, for each student, as of each testing date. For the time variables in
the level-1 model, the beginning of kindergarten during fall 1999 is point
zero. From there, we counted forward in months to the first testing date,
and—for the observation at testing point one—allotted the number of
months spent in kindergarten—as of that date—to the kindergarten time
variable. To illustrate, “Fall kindergarten”, in the “Season Duration at
Test” panel of Table 1, indicates that the average student had spent 2.2
months in kindergarten prior to the first assessment. Thus, in the obser-
vation for the test conducted at time point 1 (fall of kindergarten) the
kindergarten time variable in level 1 was coded as 2.2. For the observa-
tion at test date two—we added the number of months between test 1 and
test 2 to the number of months between point zero and test 1, and allot-
ted the total (indicated by “Spring kindergarten” in Table 1) to the
kindergarten time variable. We continued this process until we had
accounted for the exact time spent in each season as of each testing date.
To correct all misalignments between school calendars and testing
schedules, we relied on responses from the school administrator reports
indicating the exact begin and end dates for the first-grade school year.
NCES did not query school administrators during kindergarten regard-
ing these dates. Under the reasonable assumption that school calendars
did not change significantly between the 2 years, we imputed dates—for
specific schools—from first grade to kindergarten. For schools in which
school administrators failed to report begin or end dates for first grade,
we imputed the average dates for similar schools.3
Our individual, level-1 growth model is as follows:
The outcome measure, Ytij, is the test score at time tfor child iin unit
j(neighborhood or school). The intercept, 0ij, represents achievement
at school entry, and the three subsequent parameters indicate growth
rates during kindergarten, summer, and first grade, respectively. The let-
ters K, S, and F denote the seasonal time variables—beginning with Ktij
which specify the exact durations (in months) spent in each season as of
a test administration at time t. Level-1 observations occur for each testing
point (1,2, 3 and 4) for each student, except for time points when a stu-
dent’s test score was missing. The subscript iindicates the student-specific
nature of measures and parameters at level 1, and the subscript jcon-
notes membership of students within specific neighborhoods or schools.
Because reading growth rates varied substantially across seasons, the
models required separate growth parameters for each season, and this
number of parameters could not be identified given the limited number
of testing dates. Thus, we applied an error estimation strategy developed
by seasonal researchers (Downey et al. 2004) who have fitted growth
models to ECLS-K data. This strategy makes the level-1 error variance a
known quantity—thus eliminating the need for estimating this additional
parameter—by computing this variance from the published test reliabili-
ties and observed sample variance in test scores among students. The
error term at level 1, etij, represents the difference between the student’s
true performance on the test and the scale score measured by the test
instrument. This measurement error (sigma-squared) can be computed
as the product of the test unreliability [1.0 minus the instrument reliabil-
ity] multiplied by the observed variance in test scores. The NCES assess-
ment validation report (Rock & Pollack, 2002) contains the assessment
reliabilities for the reading achievement tests administered to ECLS-K
students at each testing point. Because reliabilities and score variances
varied slightly across tests, we computed an average of the measurement
error variances across the four test administrations, weighted by the pro-
portion of students taking the test at each time point. The error variance
ranged from 5.15 points for the fall 1998 test to 6.42 points for the fall
1999 test, and our computed figure for measurement error variance was
5.89. When estimating our models in HLM 6.06 (Raudenbush, Bryk, &
Congdon, 2008), we constrained the value of sigma-squared to this value.

The Level-2 Model
Level-2 comprises 4 submodels which separately explain the intercept
and growth parameters from level 1 as functions of a unit mean (the
level-2 intercept) and unit-average parameters corresponding to the
sociodemographic characteristics of individual students. The full level-2
model explaining variation among students in kindergarten reading
growth was as follows:
10j represents the unit-average growth rate during kindergarten. Each
subsequent beta parameter captures alterations to the unit average
growth rate associated with student characteristics represented by the
sociodemographic variables. Thus,
11j through
14j capture deviations
associated with each of the four family SES quintile categories denoted by
SESQUINTS—the vector of 4 socioeconomic quintiles (low, low-middle,
upper-middle, and high)—compared to the excluded category (middle-
SES).
15j through
18j capture differences in achievement growth associ-
ated with each race/ethnicity category contained within RACE—the
vector of four dummy variables for student race/ethnicity—compared to
White race/ethnicity.
19j captures the benefit associated with 2-biologi-
cal parent family structure—indicated by the dummy variable 2BIOPAR
compared to all other family formations.

10j captures the effect
associated with adding each sibling to a student’s family, and corresponds
to NUMSIBS, which specifies the number of siblings in each student’s
household.
111j captures the increment or decrement associated with
each one month deviation from the mean age at kindergarten entry rep-
resented by AGE, the student’s age in months at the beginning of the
1999 school year.
111j refers to departures from the mean age at kinder-
garten entry because AGE was centered around the sample (grand)
mean.
112j estimates the achievement decrement for male students com-
pared to females, corresponding to the dummy variable for gender, GEN-
DER. Finally,
113j captures the deviation from the unit average growth
rate associated with a student having repeated kindergarten, as indicated
by the dummy variable REPEAT, which indicates whether the student was
repeating kindergarten as of the beginning of the 1999 school year. The
level-2 error term, r1ij, represents the student-specific error term for stu-
dent iin unit j. Identical level-2 submodels predict the achievement para-
meters for school entry and first grade; the model predicting summer
season achievement growth differs slightly because it includes a dummy

variable and corresponding parameter for academic summer school
participation.
The Level-3 Model
The level-3 equations serve as a random intercept model (Raudenbush &
Bryk, 2002), in which separate level-3 equations explain the level-2 (unit-
average) intercepts for achievement at school entry,
00j, and each of the
unit-average seasonal growth parameters,
10j,
20j, and
30j. Each level-3
model (Models 1 through 4) includes random parameters that capture
achievement variation across units (neighborhoods and schools). The
average sizes of these parameters are presented in the bottom panels of
Tables 2 and 3, under the heading “Level 3 variance.” Subsequent to
Model 1—which includes only random parameters at level 3—Models 2
through 4 estimate fixed effects for the seasonal averages as well as the
contextual measures. For example, the level-3 equation, which modeled
unit-to-unit variation in the kindergarten growth parameter, was as
follows:
The intercept,
100j, represents the average kindergarten growth rate
for all units in the sample, net of the student-level predictors at level 2.
The random parameter,
10j, represents the deviation of unit jfrom this
unit-mean growth rate. In Model 1 (which contains submodels for each
season),
10j is the only level-3 parameter accompanying the intercept. In
Model 2, PROPMIN is a continuous variable indicating the percentage of
minority students in a unit, and
103 estimates the deviation from the
unit-mean growth rate associated with each one-unit (100 percentage
point) increase in the minority composition of a unit. In Model 2 and
subsequent models, the dichotomous variable FDKIND indicates whether
the school implemented a full-day kindergarten schedule, and
104 esti-
mates the fixed effect of this schedule on kindergarten achievement
growth. In Models 3 and 4, the dummy variable SES_LOW indicates
whether a unit was located in the bottom socioeconomic quintile of
neighborhoods (or schools), and
101 captures the average achievement
decrement (or increment) associated with a unit’s inclusion in this quin-
tile. Similarly, SES_HIGH indicates whether a unit was located in the top
socioeconomic quintile of units, and
102 captures the average achieve-
ment increment (or decrement) associated with a unit’s membership in
this quintile. Similar level-3 models explained achievement at school
entry and growth during summer and first grade, with the exception

that these models did not include a measure or parameter for full-day
kindergarten.
Fitting Models
Model fit was evaluated for all models by comparing random-intercept
models (specified above) to more complex random-coefficients models
including additional random error terms for level-2 covariates
(Raudenbush and Bryk, 2002). We compared our simpler models to
more complex ones using chi-square tests which employed test statistics
computed by dividing the difference in deviance statistics (numerator)
by the degrees of freedom (denominator) for each pair of models. The
deviance statistics and numbers of parameters estimated are included at
the bottom of Tables 2 and 3. We evaluated the appropriateness of ran-
dom coefficients models by allowing the slopes of level-2 covariates to
vary across units. We evaluated whether each level-2 covariate varied sig-
nificantly across units, and in cases where one did, we compared model
fit statistics between the simpler random-intercept model and the ran-
dom-coefficients model. We found few instances in which level-2 covari-
ate estimates differed significantly across units. After evaluating whether
freeing the covariate slopes (for each of these instances) produced better
fitting models using the chi-square test, we concluded that additional
error terms were prudent for only one level-2 covariate, in a limited num-
ber of seasons. In the students-within-neighborhoods analysis, we
improved model fit by freeing the slope for high-SES students in the ini-
tial status (intercept) portion of each model. In the students-within-
schools analysis, we freed the slope for high-SES students for the school
entry and first grade portions of each model. Thus, the best fitting mod-
els for the analysis were random-intercept models with the minor adjust-
ments just noted.
Notes
1. NCES did not provide students’ home zip codes during kindergarten, and thus it
was impossible to check whether students changed residences during kindergarten.
2. The great majority of schools were homogeneous in the length of their kinder-
garten offerings, with only 10% offering both half-day and full-day classes.
3. To estimate dates for similar schools, we computed average begin and end dates for
schools in each state by school sector (public or private). When we imputed a date, we used
the sector-specific date for the state in which the school was located.

Note
1. The descriptive statistics reflect the cases for which data were present. 230 students
were eliminated from the analytic sample because they were missing test scores for all test-
ing dates or were missing parent data, or were missing both.

... Overall, 41% (19/46) of studies examining academic outcomes showed a summertime decline in academic performance [29,42,60,66,67,71,79], while 37% (17/46) showed mixed findings [28,56,57,65,70,78,83,84,89,90], and 22% (10/46) indicated improvements [16,24,34,51,53,58,59,105]. A total of 89% of studies (24/27) comparing academic performance during the summer vs. the school year predominantly revealed a dip during the summer (not shown in Figure 3) [16,24,25,[27][28][29]38,40,44,48,49,56,62,63,66,67,70,71,82,90,91,97,98,103,106]. ...

Background: The school day provides a supportive and stimulating environment that may protect children and adolescents (5-18 years) from behaviours that are adverse for health and wellbeing. Objective: To review the literature regarding changes in children's academic achievement or overall wellbeing during the extended school summer break and evaluate if the outcomes are different for children experiencing disadvantage. Methods: The peer-reviewed literature was searched across six electronic databases for studies tracking changes in any academic, health or wellbeing outcome in children over the summer holidays. Studies were screened in duplicate for inclusion. Data were extracted using a standardized data extraction form. Outcomes were coded as decline (suggestive or significant), increase (suggestive or significant) or mixed/neutral and then compared to the school year or according to disadvantaged. Results: Seventy-six studies (n = 14,230,846 participants) were included. Strong evidence was found of a decline in academic outcomes and increases in adiposity, sedentary behaviour and screen time. There was moderate evidence of declines in cardiovascular fitness and physical activity. These patterns were magnified for disadvantaged children. Limited data were available on muscular fitness, sleep, diet quality and social, emotional or mental wellbeing. A total of 80% of studies were from the United States. Most data were from children 12 years of age and younger. Conclusions: Over the summer break, children's academic and health outcomes decline. Children experiencing disadvantage display magnified losses that warrant further investigation. The summer holidays present an opportunity to improve children's health and wellbeing.
... The intersection of neighborhood racial composition with the socioeconomic contexts of neighborhoods has been discussed, even suggesting that socioeconomic status had stronger associations to student achievement (J. Benson & Borman, 2010) and students' racial identities (Byrd & Chavous, 2009). Although neighborhood racial composition and socioeconomic status were not significantly correlated in this study, the relation between neighborhood racial composition, socioeconomic status, and school communal socialization (and culturally sustaining practice more broadly) is an area for future study. ...

Studies have primarily identified the positive associations between students’ communal values and teachers’ culturally relevant practice in separate investigations. The current study examined African American students’ perceptions of their mathematics teachers’ practice specifically related to the transmission of communal values, communal socialization. It also explores associations between these perceptions and students’ academic engagement and performance in mathematics. Communal socialization is the transmission of implicit and explicit messages, models, and experiences that teach, honor, and reinforce students’ values of social connectedness, interdependence, and common purpose. African American high school students (N = 308, 81% 14–17 years old, 74% female, 71% subsidized lunch status) participated in this study. Exploratory factor analyses were used to examine the dimensionality of communal socialization. Latent profile analyses yielded profiles to explore the varied experiences of students in secondary mathematics. Multinomial logistic regressions were used to examine the associations between communal socialization and students’ academic (i.e., academic engagement and performance), achievement motivation (i.e., attainment value), and social responsibility outcomes. Results were in support of the multidimensional nature of the Communal Socialization Scale including four factors: personal responsibility, community utility, equitable actions, and global responsibility. In addition, four latent profiles emerged, each with distinct levels in these factors: highly communal, moderately communal, least critical, and least communal. Students in the highly communal socialization profile reported significantly more value for mathematics, academic engagement, and perceived higher social responsibility. As a culturally sustaining practice, communal socialization has the potential to shape mathematics instruction toward fostering and sustaining social and community connections for the benefit of students’ value, engagement, and persistence in mathematics.
... School composition has been proposed as a key factor in academic achievement in several studies. In most of these studies, school SES has been operationalized as the average of students' individual SES [13,[21][22][23][24]. Moreover, some studies point to the fact that school climate, teacher practices and attitudes, as well as emphasis on academic achievement may be found to differ in low-SES schools when compared to more affluent schools [25]. ...

Effective literacy skills are essential to actively participate in today’s society. However, little research has been conducted that examined the impact of contextual variables on literacy development. The present paper addressed whether and how the socioeconomic status of the school (S-SES) children attend affects their literacy achievements. Eight-hundred and seventy-eight 2nd and 4th grade children participated in the study. Data were collected in low-SES (vulnerable) and in mid-high-SES (non-vulnerable) schools. Children completed a large battery of language, cognitive, and literacy tasks in Catalan, a language spoken in a region in Spain where virtually all children are at least bilingual (they also speak Spanish) and it is the main language of instruction. Results showed that children in vulnerable schools were outperformed by children in non-vulnerable schools across all literacy competencies, but particularly affected higher order skills; that is, text quality and reading comprehension. Differences with their non-vulnerable peers remained, even after controlling for context-level covariates, including familial SES. However, S-SES ceased to exert significant influence once children’s cognitive and, especially, linguistic skills were considered. The study adds to previous research claiming that school SES has an effect on students’ literacy skills, above and beyond children’s home SES. However, our findings also suggest that literacy performance is ultimately mostly dependent on educationally actionable, subject-level skills. Educational implications are discussed.
... Therefore, biases present within the classroom might have a smaller effect on students' AP exam performance than they would on, e.g., students' AP course performance. Second, student academic performance is influenced by a large set of factors, including student experiences in early years of schooling (Benson and Borman 2010;Clotfelter et al. 2009;Fryer and Levitt 2006) and out-of-school circumstances (Ainsworth 2002;Chetty et al. 2020;Condron 2009). Thus, the influence of racialized experiences in any particular class may have a relatively modest effect on exam passage. ...

Whether racial disparities in enrollment in advanced high school coursework can be attributed to differences in prior academic preparation is a central empirical question in sociological research, with important implications for education policy. However, the regression-based approaches to this question that are predominant in the literature suffer significant methodological limitations by implicitly assuming that students are similarly prepared if and only if they have similar values on a selected set of academic background measures. Here, we provide a general technique to estimate enrollment disparities in advanced coursework between similarly-prepared students of different races that is less vulnerable to these limitations. We introduce a novel measure of academic preparedness, a student's ex-ante probability of "success" in the course, directly adjust for this single measure in a regression model of enrollment on race, and assess the robustness of estimated disparities to potential unmeasured confounding. We illustrate this approach by analyzing Black-White disparities in AP mathematics enrollment in a large, urban, public school system in the United States. We find that preexisting differences in academic preparation do not fully explain the under-representation of Black students relative to White students in AP mathematics, and contrast our results with those from traditional approaches.

Robust literatures separately estimate school effects and neighborhood effects on children's educational, economic, health, and other outcomes that measure well-being. A growing body of research acknowledges that both contexts matter and considers neighborhoods and schools jointly. In this review, we synthesize the array of results that emerge from these studies and critique the tendency for researchers to evaluate which matters more, neighborhoods versus schools. We propose a reorientation of this scholarship that incorporates research on neighborhood and school selection and segregation processes. We argue that contextual effects research would be enriched by considering local neighborhood–school structures: the ways that families choose neighborhoods and schools and that neighborhoods and schools mutually and cyclically constitute one another. We conclude with recommendations for bringing neighborhood–school structures to bear on both outcomes-oriented studies of neighborhood and school effects as well as studies of contextual selection and segregation. Expected final online publication date for the Annual Review of Sociology, Volume 49 is July 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Educational sociologists have paid relatively little attention to children in middle childhood (ages 6 to 12), whereas developmental psychologists have emphasized factors internal to the child much more than the social contexts in explaining children’s development. Children, Schools, and Inequality redresses that imbalance. It examines elementary school outcomes (e.g., test scores, grades, retention rates) in light of the socioeconomic variation in schools and neighborhoods, the organizational patterns across elementary schools, and the ways in which family structure intersects with children’s school performance. Adding data from the Baltimore Beginning School Study to information culled from the fields of sociology, child development, and education, this book suggests why the gap between the school achievement of poor children and those who are better off has been so difficult to close. Doris Enwistle, Karl Alexander, and Linda Olson show why the first-grade transition?how children negotiate entry into full-time schooling?is a crucial period. They also show that events over that time have repercussions that echo throughout children’s entire school careers. Currently the only study of this life transition to cover a comprehensive sample and to suggest straightforward remedies for urban schools, Children, Schools, and Inequality can inform educators, practitioners, and policymakers, as well as researchers in the sociology of education and child development.

Article
In a random sample of Baltimore school children over the first 2 years of school, there are no direct effects of parent configuration on marks or test score gains in reading and math with one exception: African American children in single-mother families where other adults are present got higher marks in reading at the beginning of 1st grade than did their counterparts in mother- only or mother-father families. Irrespective of family type, however, children whose families had more economic resources and whose parents had higher expectations for their school performance consistently outperformed other children in reading and math. These findings suggest that the effects of parents' psychological and economic resources that are correlated with family type go far toward explaining previous reports of schooling deficits for children from single-parent homes, especially in the early grades.
Article
This paper suggests that students' opportunities to learn may be stratified both between and within schools: Schools serving a more affluent and able clientele may offer more rigorous and enriched programs of study, and students in college-preparatory curricular programs may have greater access to advanced courses within schools. This notion is tested with a longitudinal, nationally representative sample of public school students from the High School and Beyond data base. The results show few between-school effects of school composition and offerings but important within-school influences of curriculum tracking and coursetaking. In most cases, the difference in achievement between tracks exceeds the difference in achievement between students and dropouts, suggesting that cognitive skill development is affected more by where one is in school than by whether or not one is in school.
