There is growing evidence that investment in school facilities, and new school construction in particular, can improve K-12 student outcomes, particularly for low-income students. Funding for school infrastructure, however, is inequitably distributed. Moreover, given a lack of national data on school facilities, researchers have focused on…

Does relaxing strict school discipline improve student achievement, or lead to classroom disorder? We study a 2012 reform in New York City public middle schools that eliminated suspensions for non-violent, disorderly behavior, replacing them with less disruptive interventions. Using a difference-in-differences framework, we exploit the sharp…

Targeted instruction is one of the most effective educational interventions in low- and middle-income countries, yet reported impacts vary by an order of magnitude. We study this variation by aggregating evidence from prior randomized trials across five contexts, and use the results to inform a new randomized trial. We find two factors explain…

Four-day school weeks are becoming increasingly common in the U.S., but their effect on achievement is not well-understood. Using a difference-in-differences approach, we conduct the most representative student-level analysis to date of the effects of four-day weeks on student achievement and within-year growth using NWEA MAP Growth data. We…

A fundamental question for education policy is whether outcomes-based accountability including comprehensive educator evaluations and a closer relationship between effectiveness and compensation improves the quality of instruction and raises achievement. We use synthetic control methods to study the comprehensive teacher and principal evaluation…

Policymakers have renewed calls for expanding instructional time in the wake of the COVID-19 pandemic. We establish a set of empirical facts about time in school, synthesize the literature on the causal effects of instructional time, and conduct a case study of time use in an urban district. On average, instructional time in U.S. public schools is…

The effect of school closures in the spring of 2020 on the math, science, and reading skills of secondary school students in Poland is estimated. The COVID-19-induced school closures lasted 26 weeks in Poland, one of Europe's longest periods of shutdown. Comparison of the learning outcomes with pre- and post-COVID-19 samples shows that the…

Currently 15 percent of U.S. students receive special education services, a widespread intensive intervention with variable effects on students. Spurred by changes in federal policy, many states and districts have begun adopting the Response to Intervention (RTI) approach to identifying students to receive special education services. RTI seeks to…

There is growing concern that some nonprofit public service providers may be nonprofit in name but not in fact. We consider this concern in the context of nonprofit charter schools, which sometimes subcontract their daily operations to for-profit management organizations. We use unique data from Ohio to study how nonprofit charter schools'…

Growing up in poverty presents numerous nonacademic barriers that impede academic progress for economically disadvantaged students (Duncan and Murnane, 2016). Because schools alone have limited capacity to address the systemic nature of economic inequalities that directly affects student outcomes, policymakers and researchers in recent years have…

Efforts to attract and retain effective educators in high poverty public schools have had limited success. Dallas ISD addressed this challenge by using information produced by its evaluation and compensation reforms as the basis for effectiveness-adjusted payments that provided large compensating differentials to attract and retain effective…

Prior research has found that financial investments in North Carolina's early childhood education programs--Smart Start and NC Pre-K--generated positive effects on student achievement in reading and mathematics through eighth grade (Bai et al., 2020). The current study examined if these effects were moderated by two dimensions of educational…

We document that recent generations of elementary school teachers are significantly more effective in raising student test scores than those from earlier generations. Measuring teachers' value-added for Black and white students separately, the improvements in teaching for Black students are significantly larger than those seen for white students.…

The COVID-19 pandemic resulted in substantial unfinished learning for U.S. students, but to differing degrees for various subgroups. For example, students of color, from low-income families, or who attended high-poverty schools experienced greater unfinished learning. In this study we examined the degree of unfinished learning for students who…

We study whether reallocating existing teachers across schools within a district can increase student achievement, and what policies would help achieve these gains. Using a model of multi-dimensional value-added, we find meaningful achievement gains from reallocating teachers within a district. Using an estimated equilibrium model of the teacher…
