Background or Context: Dual language education aims to foster the development of bilingualism, biliteracy, sociocultural competence, and academic skills in all school subjects. Early correlational research suggests that participation in dual language education is associated with higher achievement. Recent studies leveraged more comprehensive sets…

Effective mathematics education for Latinx students with learning disabilities (LD) necessitates teachers who uphold high academic expectations, facilitate access to rigorous math curricula, and champion inclusive and meaningful student participation. This study delves into teachers' perspectives on instructing Latinx students with LD, including…

Although Black and Latinx students disproportionately face exclusionary school discipline, prior research finds that the likelihood of suspension for Black students decreases when they are taught by greater proportions of Black teachers. Little prior work, however, has examined whether these effects generalize to large, diverse, urban school…

Low-income and racial/ethnic minority children are at increased risk of experiencing summer reading loss or declined reading levels due to time away from school. The purpose of this study was to determine whether a 6-week summer reading program would help children maintain or improve reading levels. Four-hundred-fourteen African American and…

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…

Principals' beliefs and actions have powerful outcomes in the lives of the students and families they serve. In this article, we offer the portrait of a long-standing principal of a diverse urban school where the student body is 90% Latinx, 65% English learners (ELs), and 87% eligible for free or reduced-price lunch. We explore many key practices…

Two decades ago, the New Jersey Supreme Court in "Abbott v. Burke" mandated that the state establish high quality preschool education in the 31 highest-poverty school districts. New Jersey created a pre-K program with high standards and a continuous improvement system that transformed a patchwork of private and public programs into a…

The purpose of this research is to examine the English language proficiency trajectories of 2,201 fourth- through eighth-grade Latino English learner (EL) students who differed by current English language proficiency and were enrolled in a dual language program. Results showed that (1) students in the four English language proficiency groups…

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…

Although Black and Latinx students disproportionately face exclusionary school discipline, prior research finds that the likelihood of suspension for Black students decreases when they are taught by greater proportions of Black teachers. Little prior work, however, has examined whether these effects generalize to large, diverse, urban school…

The Kauffman School is a public, tuition-free charter school serving Kansas City students. In the 2019-20 school year, the school enrolled 1,186 students in grades 5 through 12. Most (88 percent) of the students were low income, and 89 percent were Black or Hispanic. To measure the impact of the Kauffman School on its students, the authors…

California's shift towards continuous improvement in education makes understanding how districts and schools can learn to improve a more pressing question than ever. The CORE Improvement Community (CIC), a network of California school districts engaged in learning about improvement together, is an important testing ground to learn about what 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…
