Institutional heterogeneity in the education and earnings returns to postsecondary technical education: Evidence from Missouri
We estimate the education and earnings returns to enrolling in technical two-year degree programs at community colleges in Missouri. A unique feature of the Missouri context is the presence of a highly regarded, nationally ranked technical college: State Technical College of Missouri (State Tech… more →
Weighting for Progressivity? An Analysis of Implicit Tradeoffs Associated with Weighted Student Funding in Tennessee
Tags:We study the progressivity of state funding of school districts under Tennessee’s weighted student funding formula. We propose a simple definition of progressivity based on the difference in exposure to district per-pupil funding between poor and non-poor students. The realized progressivity of… more →

Wes Austin, Bengie Chen, Dan Goldhaber, Eric A. Hanushek, Kris Holden, Cory Koedel, Helen F. Ladd, Jin Luo, Eric Parsons, Gregory Phelan, Steven G. Rivkin, Tim Sass, Mavzuna Tureava.Topics: Teacher and Leader DevelopmentTags: Leadership, PrincipalsAnecdotal evidence points to the importance of school principals, but the limited existing research has neither provided consistent results nor indicated any set of essential characteristics of effective principals. This paper exploits extensive student-level panel data across six states to… more →
Could shifting the margin between community college and university enrollment expand and diversify university degree production in STEM fields?
We examine the potential to expand and diversify the production of university STEM degrees by shifting the margin of initial enrollment between community colleges and 4-year universities. Our analysis is based on statewide administrative microdata from the Missouri Department of Higher Education… more →
Holding Back to Move Forward: The Effects of Retention in the Third Grade on Student Outcomes
Topics: Student LearningWe evaluate the effects of grade retention on students’ academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the… more →
Using Predicted Academic Performance to Identify At-Risk Students in Public Schools
Topics: Student LearningTags: Assessment, EquityMeasures of student disadvantage—or risk—are critical components of equity-focused education policies. However, the risk measures used in contemporary policies have significant limitations, and despite continued advances in data infrastructure and analytic capacity, there has been little… more →
The narrowing gender wage gap among faculty at public universities in the U.S.
Tags: Higher education, EquityWe study the conditional gender wage gap among faculty at public research universities in the U.S. We begin by using a cross-sectional dataset from 2016 to replicate the long-standing finding in research that conditional on rich controls, female faculty earn less than their male colleagues. Next… more →
Free and reduced-price meal eligibility does not measure student poverty: Evidence and policy significance
Topics: Families and CommunitiesFree and reduced-price meal (FRM) enrollment is commonly used in education research and policy applications as an indicator of student poverty. However, using multiple data sources external to the school system, we show that FRM status is a poor proxy for poverty, with enrollment rates far… more →
The Effect of the Community Eligibility Provision on the Ability of Free and Reduced-Price Meal Data to Identify Disadvantaged Students

This has implications for the… more →
The Formalized Processes Districts Use to Evaluate Mathematics Textbooks

Campbell, Cory Koedel, Quynh Tien Le, Tenice Hardaway, Hovanes Gasparian.Tags: Curriculum, Mathematics educationTextbooks are a widely used educational intervention that can affect student achievement, and the marginal cost of choosing a more effective textbook is typically small. However, we know little about how textbooks get from the publisher to the classroom. We use a lens of institutional theory and… more →
