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…

Has the gap in average standardized test scores between students from high- and low-income families widened, narrowed, or remained stable over the last 3 decades? The question is important both because the achievement gap is measure of how (un)equally educational opportunities are distributed in the US, and because the disparity in educational…

Through the examination of a collection of macro factors and explanations for racial disparities in mathematics assessment found in the literature, this article takes up these accounts and problematizes the factors by unpacking the assumptions and exposing complexities. We do this using Critical Race Theory (CRT) to reinterpret and call out…

Evaluators report effects of education initiatives as standardized effect sizes, a scale that has merits but obscures interpretation of the effects' practical importance. Consequently, educators and policymakers seek more readily interpretable translations of evaluation results. One popular metric is the number of years of learning necessary to…

This study presents a conceptual and evidentiary study pertaining to the micro and macro level factors influencing the achievement gap among migrant children from a cross-national standpoint. First, this study provides the most systematic investigation of the immigrant educational paradox theory, which asserts that on average, immigrants'…

International achievement measures such as the Programme for International Student Assessment (PISA) have traditionally reported a significant gap between non-migrant and immigrant student groups--a result that is often referred to as the "immigrant performance disadvantage". This article examines first- and second-generation immigrant…

The purpose of this study was to explore the differential effects of access to gifted education on the mathematics and science achievement of fourth-grade Black girls. This study utilized mean difference effect sizes to examine the magnitude of differences between groups. By convention, White girls were included as a comparison group. Girls…

The goal of this article is to explore the heterogeneity of state investments in elementary and secondary education over the period from 1993 to 2013, evaluating both the level of funding over time and the extent to which funding is targeted to districts serving high-poverty populations. This paper then explores a) whether those levels and…

Although approximately 5-8% of students have a mathematical learning disability (MLD), researchers have yet to develop a consensus operational definition. To examine how MLD has been identified and what mathematics topics have been explored, the authors conducted a systematic review of 165 studies on MLD published between 1974 and 2013. To move…

Federal regulations indicate that the achievement gap must be closed between subgroups, including the gap between special education and non-special education students. We explored the ways in which achievement trends are influenced by three methods of reporting (cross-sectional, cohort-static, and cohort-dynamic). We also investigated (a) the ways…

This study uses a North Carolina administrative data set to analyze racial segregation and student achievement in Wake County during race-based and income-based school assignment plans. We find a modest increase in the level of racial segregation in Wake schools during the income-based plan, but compared with other large districts in the state,…

The link between reading and mathematics achievement is well known, and an important question is whether readability factors in mathematics problems are differentially impacting student groups. Using 20 years of data from the National Assessment of Educational Progress and the Trends in International Mathematics and Science Study, we examine how…

This report features components of Arizona's plan under the Every Student Succeeds Act that impact the 85,000 English learners in the state regarding testing, accountability, and stakeholder engagement. Advocates can use this information to engage administrators and policymakers around improving outcomes for English learners and ensuring they…

This report features components of California's plan under the Every Student Succeeds Act that impact the 1.3 million English learners in the state regarding testing, accountability, and stakeholder engagement. Advocates can use this information to engage administrators and policymakers around improving outcomes for English learners and ensuring…

How are California's students doing? And are all groups of students receiving the same opportunities for educational success? How do patterns of educational outcomes in California compare to those in other states, and how have they changed in the last decade? In this study, the authors seek to provide a portrait of the state of educational…
