We evaluate the effects of grade retention on students' academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third-grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the effects persist into middle school. We find no evidence…

Summer learning loss is a perennial concern for educators and parents alike. However, researchers have recently questioned whether summer learning loss is just a statistical artifact driven by how achievement is measured across the school year. In this study, we empirically investigated a plausible critique of summer learning loss research, namely…

Few interventions reduce inequality in reading achievement, let alone higher-order thinking skills, among adolescents. We study policy debate--an extracurricular activity focused on improving middle and high schoolers' critical thinking, argumentation, and policy analysis skills--in Boston schools serving large concentrations of economically…

While research supports later start times for secondary schools, there is little evidence regarding start times for elementary schools. We address this gap with a statewide examination of elementary schools and a quasi-experimental analysis of an urban district that recently changed its elementary start times. We find that earlier start times…

School district consolidation is one of the most widespread education reforms of the last century, but surprisingly little research has directly investigated its effectiveness. To examine the impact of consolidation on student achievement, this study takes advantage of a policy that requires the consolidation of all Arkansas school districts with…

Aggregated data meta-analyses indicate a correlation between instructional leadership and student achievement. However, it is unclear to what extent this relationship can be generalized across cultural contexts, as most primary studies stem from Anglophone regions. Drawing on international large-scale assessment data, this 3-level individual…

Black and Latinx students are underrepresented in advanced placement (AP) and dual enrollment (DE), and implicit bias of educators has been discussed as one potential contributor. This study tests whether aggregate measures of implicit and explicit racial bias are related to AP and DE participation and racial/ethnic gaps in participation,…

Frames shape public opinion on policy issues, with implications for policy adoption and agenda-setting. What impact do common issue frames for racial equity in education have on voters' support for racially equitable education policy? Across survey experiments with two independent representative polls of California voters, framing effects were…

Kentucky's Targeted Interventions (TI) program is a statewide intervention intended to prepare non-college-ready high school students for college-level coursework. Using a difference-in-regression discontinuity design, we find that TI reduces the likelihood that students enroll in remedial courses by 8 to 10 percentage points in math. These…

A growing literature measures the impact of education interventions in low- and middle-income countries on both access and learning outcomes. But how should one contextualize the size of impacts? This article provides the distribution of standardized effect sizes on learning and access from 234 studies in low- and middle-income countries. We…

This article examines the influence of teacher assistants and other personnel on outcomes for elementary school students during a period of recession-induced cutbacks in teacher assistants. Using panel data from North Carolina, we exploit the state's unique system of financing its local public schools to identify the causal effects of teacher…

We examine whether the El Dorado Promise, a guaranteed college scholarship program for students in the El Dorado School District (EDSD), affected elementary and middle school achievement using a quasi-experimental matching design. We first match the EDSD with similar districts to create a pool of potential comparison students then match students…

States and districts are increasingly incorporating measures of achievement growth into their school accountability systems, but there is little research on how these changes affect the public's perceptions of school quality. We conduct a nationally representative online survey experiment to identify the effects of providing participants with…

Although the majority of elementary school teachers cover all major subjects in self-contained classrooms, a growing number of teachers specialize in teaching fewer subjects to higher numbers of students. We use administrative data from Indiana to estimate the effect of teacher specialization on teacher and school effectiveness in elementary…

The recent Every Student Succeeds Act (ESSA) requires states to identify and turn around their lowest performing schools, but it breaks somewhat from prior policies by granting states significant autonomy over how they identify and turn around these schools. This mixed-methods study, which draws on administrative, qualitative, and survey data,…
