We examine the impact of remedial and developmental courses on college students with varying levels of academic preparedness, thus focusing on a wider range of students than previous studies. Using a regression discontinuity design, we provide causal estimates of the effects of placement in different levels of remedial courses on short-,…

English as a second language (ESL) courses seek to address a primary barrier to college success for language minority students: second language issues that can inhibit their success in college-level coursework. But, there is a limited understanding of the effects of ESL on college student outcomes. Using a rich, longitudinal data set that includes…

Using a novel design approach, a randomized experiment (RE) was embedded within a regression discontinuity (RD) design (R-RE-D) to evaluate the impact of developmental mathematics at a large midwestern college ("n" = 2,122). Within a region of uncertainty near the cut-score, estimates of benefit from a prospective RE were closely…
