Amidst growing public concern in the United States over college access and affordability, federal policymakers have implemented many low-cost, behaviorally-informed strategies aimed at simplifying the college-going process and reducing informational barriers. Our paper reviews recent U.S. federal policies and interventions that draw on insights from the behavioral sciences to help students navigate various stages of the college-going process and summarizes empirical evidence of these efforts on college outcomes, highlighting variations across interventions and for various student populations. We conclude with up-to-date discussions of policy proposals and opportunities for behavioral science applications in postsecondary education.
