This study reports the findings from a year-long randomized evaluation assessing the impact of assigning 62 classrooms in Nigeria to receive either blocked or interleaved math problem sets. Blocked practice sessions focused on a single skill at a time. Interleaved problem sets alternated between...

School districts historically approached conflict-resolution from a zero-sum perspective: suspend students seen as disruptive and potentially harm them, or avoid suspensions and harm their classmates. Restorative practices (RP) -- focused on reparation and shared ownership of disciplinary...

Does a school district that expands school choice provide better outcomes for students than a neighborhood-based assignment system? This paper studies the Zones of Choice (ZOC) program, a school choice initiative of the Los Angeles Unified School District (LAUSD) that created small high school...

Many personal and policy decisions turn on perceptions of school effectiveness, defined here as the causal effect of attendance at a particular school or set of schools on student test scores and other outcomes. Widely-disseminated school ratings frameworks compare average student achievement...

Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on 3rd grade test scores. Using an augmented regression...

Most U.S. high school courses separate classrooms into standard and honors tracks. This paper characterizes the efficiency and distributional impact of changing the share of students enrolling in honors classrooms. Using a sorting model where students choose tracks by course but schools...

School assignment policies are a key lever to increase access to high performing schools and to promote racial and socioeconomic integration. For over 50 years, the Metropolitan Council for Educational Opportunity (METCO) has bussed students of color from Boston, Massachusetts to relatively...

We measure the effect of district use of federal pandemic relief during the 2022-23 school year for a sample of more than 5000 districts in 29 states. We rely on several plausibly exogenous sources of variation in federal grants: differences in state Title I funding formulas, estimation error in...

We use an admissions lottery to estimate the effect of a non-means tested preschool program on students' long-run earnings, employment, family income, household formation, and geographic mobility. We observe long-run outcomes by linking both admitted and non-admitted individuals to confidential...

Over sixty years following Brown vs. Board of Education, racial and socioeconomic segregation and lack of equal access to educational opportunities persist. Across the country, voluntary desegregation busing programs aim to ameliorate these imbalances and disparities. A longstanding...
