This article discusses the use of propensity scoring in experimental program evaluations to estimate impacts for subgroups defined by program features and participants' program experiences. The authors discuss estimation issues, provide specification tests, and review an overlooked data...

This paper presents findings from an experimental evaluation of Job Corps, the nation’s largest training program for disadvantaged youths. The study used survey data collected over four years, as well as tax data collected over nine years, for a nationwide sample of 15,400 treatments and...

Programs using means tests to identify low-income households face a trade-off between promoting access and ensuring program integrity. The authors use a comparison-district design to estimate the effects of a pilot program to improve the accuracy of the process of certifying students for free or...

Programs using means tests to identify low-income households face a trade-off between promoting access and ensuring program integrity. In the case of the National School Lunch Program, the U.S. Department of Agriculture recently implemented a pilot program to improve the accuracy of the process...

In education randomized control trials (RCTs), the misreporting of student outcome data could lead to biased estimates of average treatment effects (ATEs) and their standard errors. This article discusses a statistical model that adjusts for misreported binary outcomes for two-level,...

Pretest–posttest experimental designs often are used in randomized control trials (RCTs) in the education field to improve the precision of the estimated treatment effects. For logistic reasons, however, pretest data often are collected after random assignment, so that including them in...
