CUNY’s College Bridge for All is expanding the use of peer mentoring to combat “summer melt,” where admitted students fail to enroll after high school. The program is framed as a near-peer advising model guiding students through the pathway to college enrollment. The reporting situates the work as an enrollment-management and student-success intervention that addresses key decision points after acceptance—helping students navigate tasks and logistics before the start of classes. With summer melt continuing to affect institutional enrollment yields, peer support is positioned as a cost-effective strategy that can complement financial aid and admissions communications. The development adds evidence for institutions seeking operational levers beyond messaging—using mentoring to reduce barriers during the post-admission period.
