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 their implementation and there is no consensus on their effects on students. This study uses district level panel data from Oklahoma and a difference-in-differences research…

Leveraging rich data on the universe of Texas high school graduates, we estimate how the relationship between geographic access to public two- and four-year postsecondary institutions and postsecondary outcomes varies across race-ethnicity and socioeconomic status. We find that students are sensitive to the distance they must travel to access…

Using data from nearly 1.2 million Black SAT takers, we estimate the impacts of initially enrolling in an Historically Black College and University (HBCU) on educational, economic, and financial outcomes. We control for the college application portfolio and compare students with similar portfolios and levels of interest in HBCUs and non-HBCUs who…

New York City's universal pre-kindergarten program, which increased full-day enrollment from 19,000 to almost 70,000 children, is ambitious in both scale and implementation speed. We provide new evidence on the distribution of pre-K quality in NYC by student race/ethnicity, and investigate the extent to which observed differences are associated…

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'…

The federal government and many individual organizations have invested in programs to support diversity in the STEM pipeline, including STEM summer programs for high school students, but there is little rigorous evidence of their efficacy. We fielded a randomized controlled trial to study a suite of such programs targeted to underrepresented high…

The impact of school resources on student outcomes was first raised in the 1960s and has been controversial since then. This issue enters into the decision making on school finance in both legislatures and the courts. The historical research found little consistent or systematic relationship of spending and achievement, but this research…

The COVID-19 pandemic's impact on preschool children's school readiness skills remains understudied. This research investigates Head Start preschool children's early numeracy, literacy, and executive function outcomes during a pandemic-affected school year, using a novel virtual assessment methodology. Study children (N = 336; mean age = 51…

Multiple studies have documented the positive effect of school choice on college attendance. We focus instead on the quality of colleges, which is linked to higher graduation rates and later-in-life wages, especially for Black and Hispanic students. We examine the effect of the New Orleans school reforms, a district-wide reform creating an almost…

This paper examines how financial aid reform based on postsecondary institutional performance impacts student choice. Federal and state regulations often reflect concerns about the private, for-profit sector's poor employment outcomes and high loan defaults, despite the sector's possible theoretical advantages. We use student level data to examine…

We estimate the longer-run effects of attending an effective high school (one that improves a combination of test scores, survey measures of socio-emotional development and behaviours in 9th grade) for students who are more versus less "educationally advantaged" (i.e., likely to attain more years of education based on 8th-grade…
