This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

This report presents the findings of an evaluation sponsored by the Institute of Education Sciences (IES) at the U.S. Department of Education (ED) and conducted by Mathematica Policy Research (Mathematica) that uses a regression discontinuity (RD) design to assess the potential benefits of offering SES in districts that have unmet need.…

This paper presents an executive summary of a study that uses a regression discontinuity (RD) design to assess the potential benefits of offering SES in districts that have unmet need. Specifically, the study focuses on six school districts in which more eligible students applied for SES than could be served with available funds (i.e.,…

To help assess the effects of school-based random drug testing programs, the U.S. Department of Education's Institute of Education Sciences (IES) contracted with RMC Research Corporation and Mathematica Policy Research to conduct an experimental evaluation of the Mandatory-Random Student Drug Testing (MRSDT) programs in 36 high schools within…

In randomized controlled trials (RCTs) where the outcome is a student-level, study-collected test score, a particularly valuable piece of information is a study-collected baseline score from the same or similar test (a pre-test). Pre-test scores can be used to increase the precision of impact estimates, conduct subgroup analysis, and reduce bias…

This study addresses two questions related to teacher preparation and certification: (1) What are the relative effects on student achievement of teachers who chose to be trained through different routes to certification and how do observed teacher practices vary by chosen route to certification?; and (2) What aspects of certification programs…

This document reports on the impacts on student achievement for four supplemental reading curricula that use similar overlapping instructional strategies designed to improve reading comprehension in social studies and science text. Fifth-grade reading comprehension for each of three commercially-available curricula (Project CRISS, ReadAbout, and…
