Across the United States, community colleges are facing severe funding reductions and surging enrollment, resulting in a condition of impaction in which demand for coursework exceeds financial or physical capacity. In turn, impaction is necessitating changes in enrollment management policies, including rapid evolution in registration priority policies, which ration access to coursework by granting preferential course enrollment timing to students who meet specified criteria. During times of impaction, such policies effectively preclude some groups of students from making progress toward their goals or, under the worst circumstances, from attending college at all. Given the importance of community colleges for providing access to postsecondary education, these policies have significant, long-term implications. Here, we situate the discourse on registration priority policies in a larger context and body of literature, document the variation in policies across the colleges in one state, and develop a set of recommendations for policy and future research.
