The Black-White Test Score Gap Through Third Grade
Abstract
This article describes basic facts regarding the Black-White test score gap over the first four years of school. Black children enter school substantially behind their White counterparts in reading and math, but including a small number of covariates erases the gap. Over the first four years of school, however, Blacks lose substantial ground relative to other races; averaging 0.10 standard deviations per school year. By the end of third grade, there is a large Black-White test score gap that cannot be explained by observable characteristics. Blacks are falling behind in virtually all categories of skills tested, except the most basic. None of the explanations we examine, including systematic differences in school quality across races, convincingly explain the divergent academic trajectory of Black students.

Written from the paper’s full text.
TL;DR
Using ECLS-K data through third grade, Fryer and Levitt show that Black students enter school behind Whites in reading and math, but with a parsimonious set of controls the initial gap is small; over the first four years of school Blacks lose substantial ground relative to Whites. By third grade a large Black-White test score gap remains that observable characteristics, school quality, teacher fixed effects, and changing test content do not convincingly explain.
Key findings
- Raw Black-White gaps widen from .663 SD in fall-kindergarten math to .882 SD by spring third grade, and from .400 SD to .771 SD in reading. With controls, the Black coefficient in math goes from -.099 SD in fall kindergarten to -.382 SD in spring third grade; in reading it goes from +.13 SD in fall kindergarten to -.282 SD in spring third grade. Blacks lose on average .10 SD per school year relative to Whites, totaling .283 SD in math and .41 SD in reading over the first four years.
- School quality becomes less convincing as an explanation when data extend through third grade. Including school fixed effects leaves two-thirds of the Black-White difference, and all ground lost between first and third grade is within rather than across schools; teacher fixed effects produce essentially unchanged results.
- By third grade, gaps appear in every skill tested in reading and math except the most basic tasks mastered by virtually all students. The largest gaps are in multiplication/division and literal inference: over 85% of White students mastered these subjects, but mastery rates are 15–20% lower for Blacks after controls.
- Hispanics gain ground relative to Whites despite worse initial conditions, while Asians’ early advantage is maintained or diminishes depending on subject; neither group shows the Black pattern of divergence.
Methods
- Data: Early Childhood Longitudinal Study Kindergarten Cohort (ECLS-K), a nationally representative sample of over 20,000 children entering kindergarten in 1998, with tests in fall and spring kindergarten, spring first grade, and spring third grade; roughly 1,000 schools. Analysis samples are 11,201 observations for math and 10,540 for reading.
- Measures: standardized item response theory (IRT) math and reading scores, normalized to mean zero and SD one; controls include ECLS socioeconomic composite, number of children’s books and its square, gender, age, birth weight, mother’s age at first birth, and WIC participation.
- Analysis: weighted least squares cross-sectional regressions with race dummies; school and teacher fixed effects in Table 6; probit regressions for skill mastery in Table 8. Students missing test scores, race, or age are dropped.
Limitations
- Stated: the authors say a causal interpretation of covariate coefficients is likely inappropriate and view the variables as proxies for broader environmental and behavioral factors. They also state that explanations for Black students losing ground remain elusive, that school-quality evidence is not conclusive, and that the data cannot definitively determine whether Black students eventually master higher-order skills or never do.
- Stated: school fixed effects may also capture neighborhood effects because school assignment depends heavily on residential location, making school quality difficult to separate from neighborhood quality.
- Evident from the text: the analysis is observational and cross-sectional, uses data only through third grade, and relies on a limited set of proxies rather than direct measures of mechanisms such as parenting, peer norms, or instructional quality.

“Any optimism, however, is tempered by the fact that by the end of first grade (the last data used in Fryer and Levitt 2004) Black students have already lost substantial ground (the equivalent of almost three months of schooling) relative to Whites.”

- Partly supportedcites Fryer and Levitt 2004 sourceExperimental — accuracy not yet measured
Section V reports that Black students lost ground relative to White students between the start of kindergarten and the end of first grade: 0.156 standard deviations in math and 0.188 in reading after controls. Our copy does not express that loss as the equivalent of almost three months of schooling, so the claim’s magnitude in months is not supported. (LLM, conf=0.84)

The Abstract says there is suggestive evidence that school-quality differences may explain why Black children lost ground between the beginning of kindergarten and the end of first grade, while none of the other hypotheses tested received empirical backing. The section 'Are Black students losing ground because they attend worse schools?' likewise calls the school-quality evidence consistent with the explanation but not definitive proof. The claim describes empirical backing, not proof. (LLM, conf=0.91)

What the sources say
- Partly supportedcites Fryer and Levitt (2004) sourceExperimental — accuracy not yet measured
In “Are Black students losing ground because they attend worse schools” (page unavailable), the paper reports that Black students lost substantial ground relative to Whites in the full sample, while their relative loss was much smaller when compared with Whites at the same schools. This is consistent with weaker test-score trajectories at schools attended by Black students, but the paper does not establish that Whites at those schools themselves lost a substantial amount relative to Whites at other schools; it treats their possible lower trajectories as an unresolved explanation.

“Arguing against such a hypothesis, as Rock and Stenner (2004) note, is the fact that test scores in the fall of kindergarten are strongly predictive of test scores in spring of third grade; if the two tests are capturing very different sets of skills, this would not be expected.”

- The authors state this as an assumption: Children of different races are equally responsive to changes in covariates.
The authors state this as an assumption.
Children of different races are equally responsive to changes in covariates.
“The results presented in Tables 2 - 4 maintain the assumption that children of different races are equally responsive to changes in covariates.”
The paper relies on this without support.
The parsimonious set of covariates adequately captures a child's environment.
“to the extent our control variables adequately capture a child's environment, the residual gap after including all the covariates would remain constant.”
The paper relies on this without support.
The ECLS-K sample is nationally representative of children entering kindergarten in 1998.
“The Early Childhood Longitudinal Study Kindergarten Cohort (ECLS-K) is a nationally representative sample of 21,260 children entering kindergarten in 1998.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-29, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-29 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
