Although the threat of sanctions on low-performing schools can raise student test scores in the short run, the extent to which these test score improvements are due to schools' manipulation of the accountability system has remained uncertain. This article evaluates the relative importance of...

Using data on elementary and middle school math and reading outcomes for Pennsylvania students, this working paper found that school value-added provides little useful information for comparing the general leadership skills of different principals when these comparisons include some principals...

Randomized control trials (RCTs) in the education field typically examine the intention-to-treat parameter, which is estimated by comparing the mean outcomes of treatment group members to those of the control group. This report examines the identification and estimation of the complier average...
