The Louisiana Scholarship Program (LSP) offers publicly funded vouchers to students in low-performing schools with family income no greater than 250% of the poverty line, allowing them to enroll in participating private schools. Initially established in 2008 as a pilot program in New Orleans, the LSP was expanded statewide in 2012. This article…

This research examines the effects of state laws banning access to in-state resident tuition for unauthorized immigrant students in the United States. These laws were implemented between 2005 and 2012. We evaluate the policy effects on (a) college enrollment, (b) school dropout rates of unauthorized immigrants, and (c) the enrollment of U.S.…

Despite growing calls for more accountability of teacher education programs (TEPs), there is little consensus about how to evaluate them. This study investigates the potential for using observational ratings of program completers to evaluate TEPs. Drawing on statewide data on almost 9,500 program completers, representing 44 providers (183…

This article exploits a natural experiment to estimate the effects of need-based aid policies on first-year college persistence rates. In fall 2006, Ohio abruptly adopted a new state financial aid policy that was significantly more generous than the previous plan. Using student-level data and very narrowly defined sets of students, I estimate a…

We contribute to debate about causal inferences in educational research in two ways. First, we quantify how much bias there must be in an estimate to invalidate an inference. Second, we utilize Rubin's causal model to interpret the bias necessary to invalidate an inference in terms of sample replacement. We apply our analysis to an inference…

This article evaluates the impact and cost-effectiveness of offering an innovative middle school model--the Sistema de Aprendizaje Tutorial (SAT)--to Honduran villages instead of traditional middle schools. We identified a matched sample of villages with either type of school and collected baseline data among primary school graduates eligible to…

This article reports on findings based on analyses of a unique dataset collected by ACT that includes information on student achievement in a variety of subjects at the high-school level. The authors examine the relationship between teacher effect estimates derived from value-added model (VAM) specifications employing different student learning…

The No Child Left Behind Act requires states to publish high school graduation rates for public schools; the U.S. Department of Education is currently considering a mandate to standardize high school graduation rate reporting. However, no consensus exists among researchers or policymakers about how to measure high school graduation rates. We use…
