In 2019, MDRC launched the Scaling Up College Completion Efforts for Student Success (SUCCESS) project to improve college completion rates for traditionally underserved students, such as students from low-income backgrounds and students of color, at community and broad-access colleges (those that have open or minimally selective admissions policies). The SUCCESS program integrates multiple evidence-based components proven in previous studies to help students stay enrolled and graduate. Relatively little is known about how to best serve adult learners and improve their graduation rates. This brief highlights the experiences of adult students 25 years or older in the SUCCESS program at four institutions and explores how SUCCESS supports adult learners and how it, and other programs, can do more. Namely, this research reveals that: (1) students found the SUCCESS coaching component particularly valuable in terms of keeping them accountable and providing resources; (2) the full-time enrollment requirement posed a challenge for balancing academic and personal responsibilities; (3) although students appreciated the financial incentive many still had unmet financial needs; and (4) beyond the SUCCESS components, students expressed they could benefit from additional flexibility, community-building opportunities, and support with technology.
