Funders, organizations, and colleges want new models for how to improve postsecondary success rates, but working alone, they are limited by their own capacity, knowledge, and existing systems. This report describes the successful collaboration between a community-based organization (CBO) and a New York City community college focused on improving the college success rates of underrepresented, postsecondary students. Bringing their resources and strengths, the two partners provided a comprehensive support system to the underperforming students that helped in their academic, and social and developmental preparation for college. The authors describe how the collaboration began, key components of the initiative, and lessons learned for future endeavors between CBOs and postsecondary institutions.
