The reading achievement gap between Black and White students was 29 points in Florida, depicting an alarming eight-point increase over that of the United States. Within School District A, the reading achievement gap was over 40% for over 4 years resulting in a district-wide plan for reconciliation and to determine the contributing factors of the…

We examine access to effective teachers for low-income students in 26 geographically dispersed school districts over a 5-year period. We measure teacher effectiveness using a value-added model that accounts for measurement error in prior test scores and peer effects. Differences between the average value added of teachers of high- and low-income…

Ethnoracial inequality in educational achievement and attainment is a long-standing feature of the American education system. For example, national reading assessments show that White fourth graders scored nearly a standard deviation higher than Black or Hispanic students on average in 2015 (NCES, 2015). The measurement and analysis of differences…

We draw on novel district-level test score data to describe novel approaches for measuring ethnoracial achievement gaps and assessing trends toward achievement equity from 2009 to 2016. Using SEDA data, we estimate gap trends for each grade over time in each district. We measure trends in both within-district gaps--comparing Black or Hispanic to…

Despite considerable reform activity surrounding K-12 education over the past 20 years, racial and socioeconomic disparities among students who achieve at advanced levels have received little attention. This study examined how excellence gaps, defined as differences in performance at the 90th percentile of subgroups, change over time and their…

Using testing data from 2.1 million students in 10,000 schools in 49 states (plus D.C.), we investigate the role of remote and hybrid instruction in widening gaps in achievement by race and school poverty. We find that remote instruction was a primary driver of widening achievement gaps. Math gaps did not widen in areas that remained in-person…

Racial segregation has been an ongoing issue in American education and one of the leading contributors to the racial achievement gap. Prior to the Brown v. Board decision of 1954, Black Americans were legally relegated to substandard schools and educational opportunities. Post-Brown, racial segregation continues to manifest as a result of "de…

The Every Student Succeed Act (ESSA) brings significant changes as well as opportunities for schools to improve their students' academic outcomes. One proposed regulation is for states to analyze the performance of student subgroups separately in order to show how states are levelling the playing field over time to ensure educational equity. This…

This study presents estimates of Black-White, Hispanic-White, and income achievement gaps using data from two different types of reading and mathematics assessments: constructed-response assessments that were likely more cognitively demanding and state achievement tests that were likely less cognitively demanding (i.e., composed solely or largely…

This study examined factors contributing to achievement gaps between White and African American students in 2,868 diverse school districts across the United States. Using pooled data across five school years (2008-2013), six grade levels (grades third to eighth, which typically include students aged 8 years-14 years) and two different subjects…

The 2001 authorization of the No Child Left Behind Act and its standards and accountability requirements generated interest among state education agencies in Florida, Mississippi, and North Carolina, which are served by the Regional Educational Laboratory Southeast, in monitoring changes in student reading and math proficiency at the school level.…

This longitudinal study examined the outcomes of Project Excite on reducing minority students' achievement gaps in STEM over 14 years. Project Excite was designed to provide intensive supplemental enrichment and accelerated programming for high-potential, underrepresented minority students from third through eighth grades to better prepare them…

We apply a quantile version of the Oaxaca-Blinder decomposition to estimate the counterfactual distribution of the test scores of Black students. In the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K), we find that the gap initially appears only at the top of the distribution of test scores. As children age, however,…

The achievement gap has long been the focus of educational research, policy, and intervention. The authors took a new approach to examining the achievement gap by examining achievement trajectories within each racial group. To identify these trajectories they used the Early Childhood Longitudinal Study-Kindergarten Cohort, which is a nationally…

Using data from the 1998-99 ECLS-K cohort, we show that the grades awarded by teachers are not aligned with test scores. Girls in every racial category outperform boys on reading tests, while boys score at least as well on math and science tests as girls. However, boys in all racial categories across all subject areas are not represented in…
