In a 2023 report by the National Student Clearinghouse, the "some college, no credential" population stood at 40.4 million in 2021, up 3.6 percent from a year earlier. Of this population, more than half (21 million, 52%) were 25 or older at the time of their last enrollment. One solution to this reality is to reengage this population and bring them back to postsecondary learning opportunities as adults, but a common criticism is that such "Comebackers" also do not have a good track record for persisting toward credential completion. For many adult learners, the path to a degree is often punctuated by breaks in enrollment. The Council for Adult and Experiential Learning (CAEL) found the reasons for stopping out were far more likely to be related to health or personal issues, money, and time constraints than academic reasons. Notably, many adult learners viewed stopping out as taking a break rather than dropping out completely. This report discusses the reasons adult learners give for stopping out of learning and what this suggests for needed institutional supports as well as the ways in which we measure and track adult learner success.
