Gender Gaps in the Early Grades: Questioning the Narrative that Schools are Poorly Suited to Young Boys
A growing number of scholars and educational leaders have raised concerns that the mismatch between an increasingly academic focus in the early grades and boys’ maturity at school entry is disadvantaging young boys in school. In this study, we use a unique dataset of ten million students to… more →
When interventions don’t move the needle: Insights from null results in education research
As school districts focus on improving learning, they can learn not only from when and where interventions work—but also from why they sometimes do not. Policymakers widely embraced high-impact tutoring as an evidence-supported strategy to address learning delays from the COVID-19 pandemic.… more →
The Effects of Universal School Vouchers on Private School Tuition and Enrollment: A National Analysis
Three-quarters of a century after Milton Friedman popularized the idea, universal school vouchers have suddenly become a reality in 17 states since 2021. These new policies promise to be one of the most far-reaching reforms in U.S. education history. We make two contributions to understanding… more →
Investing in Human Capital During Wartime: Experimental Evidence from Ukraine
This paper provides insights into human capital investments during wartime by presenting evidence from three experiments of an online tutoring program for Ukrainian students amid Russia’s invasion of Ukraine. Conducted between early 2023 and mid-2024, the experiments reached nearly 10,000… more →
Controlling For Measurement Error in Evaluation Models When Treatment Group Assignment is Based on Noisy Measures: Evaluation of an Achievement Gap-Closing Initiative
This paper develops new models to evaluate the effects of interventions and intervention-by-site heterogeneity when treatment group assignment is based on a fallible variable and the outcome of interest is determined in part by the corresponding true control variables (measured without error).… more →
The Power of Personalized Attention: Comparing Pedagogical Approaches in Small Group and One-on-One Early Literacy Tutoring
Tutoring has played a significant role in pandemic-related learning recovery, supporting student learning and engagement. A recent randomized controlled trial estimated that one-on-one virtual early literacy tutoring was nearly twice as effective as two-on-one tutoring for improving student… more →
The impact of increasing school resources on peer victimization: Evidence from targeted funding on low-income families in Chile

Labor supply, learning time, and the efficiency of school spending: Evidence from school finance reforms
Does school spending raise achievement? I show that effects, benchmarked by schools’ daily value added, are one-tenth to one-third as large as spending growth. Using school finance reforms for identification, I show that schools did not raise quality measured by value added. Instead, schools… more →
Democracy For What and For Whom?: The Possibilities and Challenges of K-12 School Boards

As such, school boards have regularly served as critical sites for… more →
Comparing Machine Learning Methods for Estimating Heterogeneous Treatment Effects in Randomized Trials: A Comprehensive Simulation Study

Measuring Elementary School Teachers' Knowledge of Teaching Vocabulary
Teacher Knowledge in the field of literacy has become a priority across the United States, with many states passing legislation requiring that all teachers receive adequate training on the Science of Reading. One essential component of literacy development and text comprehension is vocabulary… more →
Parent Perspectives on School Choice: Experimental Evidence from a Nationally Representative Sample
Parental attitudes and perspectives of student “success” will likely drive their educational choices, whether residentially assigned district public schools, alternative public schools, private schools, or homeschooling. However, little research has examined the importance of these attitudes on… more →
High School Effects on Civic Engagement
Preparing young people for the rights and responsibilities of citizenship is cited as a fundamental purpose of public education, yet little is known about whether or how K-12 schools impact civic engagement. Using education records, birth records, and national voting records for nine cohorts of… more →
