Most students who begin at a community college do not complete their desired credential. Many students fail to graduate due to various barriers rather than their academic performance. To encourage previously successful non-completers to re-enroll and eventually graduate, a growing number of community colleges have implemented re-enrollment campaigns focused on former students who have already made substantial progress toward graduation. In this study, we randomly assigned over 27,000 former community college students to a control group, “information-only” treatment group, or “information and one-course waiver” treatment group to examine whether re-enrollment campaigns can improve their likelihood of long-term persistence and credential completion. Although we showed in earlier work that the “information and one-course waiver” treatment had a positive impact on former students' likelihood of re-enrollment, our findings reveal the re-enrollment intervention has no effect on students' likelihood of long-term persistence or credential completion for the pooled sample or any subgroup of interest, including low-income students, racially minoritized students, or adult students. Simply put, this particular re-enrollment intervention including one-time, one-course tuition waivers increased former students' likelihood of re-enrollment but was not an effective lever to increase long-term academic outcomes among previously successful community college students who departed without earning a credential.

About one third of college students are required to take remedial courses. Assignment to remediation is generally made on the basis of performance on a placement exam. When students are required to take a placement exam prior to enrolling in college-level courses, assignment to remediation may dissuade students from actually going to college. This is because remediation could increase the time required to complete a degree (because remedial courses do not count toward academic degrees), and also because being identified as needing remediation might have stigma effects or provide students with new information about their unsuitability for college. This paper examines this issue empirically using administrative data from Texas. Using regression discontinuity methods, we find that students whose placement exam scores would require them to be in remediation are no less likely to enroll in college than are students who score just above the remediation placement cutoff.
