Program and policy effects

Recent reviews of the educational intervention literature have noted patterns of intervention impact fadeout on cognitive skills, whereby skill trajectories between children in the intervention and control group converge in the years following the end of the intervention. Some early childhood… more →

Teacher evaluation systems and their associated incentives have produced fairly mixed results. Our analyses are motivated by theory and descriptive evidence that accountability systems are highly racialized, and that individuals are less likely to respond to incentives when they have low… more →

Two persistent shortcomings of the American labor market are the wage gaps and unequal unemployment rates that exist between racial groups. More specifically, Black and Latinx high school graduates earn less and are more likely to be unemployed than their White counterparts, on average. Likewise… more →

This instrumental case study explores 31 Iowan educators’ and board of education members’ perceptions of the ways the state’s book ban law, Senate File 496 influenced school information systems. Mathisen’s (2015) informational justice conceptual framework guided data analysis. The three key… more →

Counselors are a common school resource for students navigating complicated and consequential education choices. However, most students have limited access to school counselors. We study one of the largest U.S. policies to increase access to school counselors - California's Supplemental School… more →

Iowa's Senate File 496 requires parent permission to formally survey students about their mental health, bans the discussion of gender identity and sexual orientation in schools before 7th grade, mandates schools obtain parental permission to use a nick name, and bans any books that depict or… more →

Generative AI, particularly Large Language Models (LLMs), can expand access to expert guidance in domains like education, where such support is often limited. We introduce Tutor CoPilot, a Human-AI system that models expert thinking to assist tutors in real time. In a randomized controlled trial… more →

Although community colleges have served as a gateway to universities for millions of students—disproportionately so for students from populations historically underrepresented in higher education—prior research has demonstrated that the majority of vertical transfer students lose at least some… more →

A growing body of research has documented extensive credit loss among transfer students. However, the field lacks theoretically driven and empirically supported frameworks that can guide credit loss research and reforms. We develop and then test a comprehensive framework designed to address this… more →

Children spend most of their time at home in their early years, yet efforts to promote human capital at home in many low- and middle-income settings remain limited. We conduct a randomized controlled trial to evaluate an intervention which encourages parents and caregivers to foster human… more →

Whole-school reforms have received widespread attention, but a critical limitation of the current literature is the lack of evidence around whether these extensive and costly interventions improve students’ long-term outcomes after they leave reform schools. Leveraging Tennessee’s statewide… more →

Over the past decade, there has been a significant increase in the number of U.S. institutions offering STEM-eligible degree programs in economics. This paper documents the trends in STEM-degree offerings across degree levels and examines the share of foreign students and other characteristics… more →

Mastery learning – the process by which students must demonstrate proficiency with a single topic before moving on – is well recognized as one of the best ways to learn, yet many teachers struggle or remain unsure about how to implement it into a classroom setting. This study leverages two field… more →

The use of four-day school weeks (4dsw) in the United States has expanded rapidly over the past two decades. Previous work examines the impact of 4dsw on student outcomes, but little research to date examines the effect on school employees even though schools in some locales have adopted 4dsw to… more →

U.S. public schools are engaged in an unprecedented effort to expand tutoring in the wake of the pandemic. Broad-based support for scaling tutoring emerged, in part, because of the large effects on student achievement found in prior meta-analyses. We conduct an expanded meta-analysis of 282… more →

Public school systems across the U.S. have made major investments in tutoring to support students’ academic recovery in the wake of the COVID-19 pandemic. We evaluate a large urban district’s efforts to design, implement, and scale a district-operated, standards-based tutoring program across… more →

Racial disparities in infant health conditions have persisted for decades. However, there is surprisingly limited evidence regarding the long-term consequences of these disparities. Using novel linked administrative data from Texas and the shift to Medicaid Managed Care (MMC), I show that MMC-… more →

The immediate impacts of COVID-19 on K12 schooling are well known. Over nearly 18 months, students’ academic performance and mental health deteriorated dramatically. This study aims to identify if and how the pandemic led to longer-term changes in core aspects of schooling.

This paper reports findings from a nationally representative survey of K-12 teachers in May 2023 that examines the potential long-term impacts of COVID-19 on public schooling. The findings suggest fundamental ways in which school operations, instructional practice and parent-teacher interaction… more →

This study examines the effects of universal public pre-kindergarten for 3-year-olds (Pre-K3) on later public education outcomes, including enrollment, school mobility, special education status, and in-grade retention from kindergarten through second grade. While universal pre-kindergarten… more →
