Overview

Jennifer McCombs is a senior policy researcher and director of the Behavioral and Policy Science Department at the RAND Corporation. Her research focuses on evaluating the extent to which public policies and programs improve outcomes for at-risk students.

Over the course of her career, she has studied how to improve teacher effectiveness (through professional development, teacher training, and incentives); whether literacy coaching improves student reading outcomes; the development of systems for out-of-school-time programs; the implementation and impact of test-based promotion policies; and the effects of federal accountability policies on schools, classrooms, and students. McCombs currently co-leads a five-district randomized controlled trial examining the effectiveness of voluntary summer learning programs for low-income elementary youth. Her studies combine implementation and outcome data to provide practitioners and policymakers guidance on how to improve programs and promote student outcomes. She earned her Ph.D. in public policy from The George Washington University.

High-Quality Out-of-School-Time Programs Are Worthy of Investment
High-quality out-of-school-time programs can benefit youth, and tend to produce outcomes linked to program content. Funders and policymakers could maximize benefits of these programs by providing adequate resources and funding to support quality programming. It could be a wise investment for America's youth.
