We use data from the Stanford Education Data Archive to describe district-level trends in average academic achievement between 2009 and 2019. Though on average school districts' test scores improved very modestly (by about 0.001 SDs/year), there is significant variation among districts. Moreover, we find that average test score disparities between…

Though schools do not track in Brazil, I find that black/white classroom segregation in Brazil is greater than recent estimates from North Carolina high schools (Clotfelter et al., 2020). How does race-based classroom segregation occur without tracking, and in a supposed "racial paradise," no less? Using national, student-level data…

Four-day school weeks have proliferated across the United States in recent years, reaching over 650 public school districts in 24 states as of 2019, but little is known about the effects of the four-day school week on high school students. This study uses district-level panel data from Oklahoma and a difference-in-differences research design to…

Before the 2020-21 school year, educators, policymakers, and parents confronted the stark and uncertain trade-offs implied by the health, educational, and economic consequences of offering instruction remotely, in person, or through a hybrid of the two. Most public schools in the U.S. chose remote-only instruction and enrollment fell dramatically…

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…

A growing body of evidence suggests that vocationally focused programs of study substantially improve high-school completion and longer-run economic success. However, the corresponding recommendations to expand vocational programs may have unintended, negative consequences for low-income, academically successful students (i.e., the "missing…

Despite the recent dramatic rise in student homelessness in the U.S., little research evidence exists on the effects of homelessness programs and interventions on students and young people. This paper examines the effects of a homelessness prevention and rapid rehousing program--which combines temporary rental subsidies with light-touch case…

The evidence that student learning declines sharply (or stagnates) during the summer has motivated a substantial interest in programs that provide intensive academic instruction during the summer. However, the existing literature suggests that such programs, which typically focus on just one or two subjects, have modest effects on students'…

This study examines the relationship between county-level estimates of implicit racial bias and black-white test score gaps in U.S. schools. Data from over 1 million respondents from across the United States who completed an online version of the Race Implicit Association Test (IAT) were combined with data from the Stanford Education Data Archive…

Although many programs remotely disseminate information to students about the college application process, there is little evidence as to how students experience these programs. This paper examines a large-scale remote counseling program in which college counselors initiated interactions with 15,000 high school seniors via text message to support…

I examine a new generation of Career and Technical Education (CTE) models that has shifted from isolated courses to sequences of study that integrate academics and skills in specific career areas. I use data for a competitive grant administered by the California Department of Education (CDE) that incentives K-12 school districts to partner with…

The My Brother's Keeper (MBK) Challenge developed by President Obama supports communities that promote civic initiatives designed to improve the educational and economic opportunities specifically for young men of color. In Oakland, California, the MBK educational initiative features the African American Male Achievement (AAMA) program. The AAMA…

Millions of high school students take Advanced Placement (AP) courses, which can provide college credit. Using nationally representative data, I identify a diverse set of higher education outcomes that are related to receipt of AP college credit. Institution fixed effects regression reduces bias associated with varying AP credit policies and…

In the first systematic study of gender achievement gaps in U.S. school districts, we estimate male-female test score gaps in math and English Language Arts (ELA) for nearly 10,000 school districts in the U.S. We use state accountability test data from third through eighth grade students in the 2008-09 through 2014-15 school years. The average…

I use standardized test scores from roughly 45 million students to describe the temporal structure of educational opportunity in over 11,000 school districts--almost every district in the US. For each school district, I construct two measures: the average academic performance of students in grade 3 and the within-cohort growth in test scores from…
