Student debt is a major barrier to adult student reengagement and degree completion. Institutional debt forgiveness is one approach to addressing the affordability barrier for returning students. This guidebook features an interview with leaders at Wayne State University in Detroit, Michigan, who share details about the innovative debt-forgiveness program they implemented as a reenrollment strategy for students who stopped out of their university without completing a degree. In its first seven months, this program produced a net gain of $200,000 in revenue for the institution. Following the interview, a Reengagement Investment Calculator is provided to help those to help those interested in replicating this program assess their institution's own potential "Return on Investment (ROI)" for serving this population of students. For those interested in learning more about debt-forgiveness strategies, a list of additional resources to explore is provided at the end of this guidebook.
