Strategic partnerships between community-based college success programs and higher education institutions can play a critical role in students' degree completion and workforce readiness. This paper describes partnerships between four community-based organizations and higher education institutions based on interviews with staff directly involved. These organizations participated in the Success Replication Project organized by the National College Attainment Network and funded by the Michael & Susan Dell Foundation. The organizations' common goal is to improve students' college persistence and postsecondary completion rates. They use different strategies to achieve this goal, and so provide a mix of options for organizing and maximizing such partnerships. Three of the organizations profiled for this paper (Operation Jump Start, Project GRAD Houston, and Ready to Rise) have memoranda of understanding (generally referred to as an MOU), signed by organization and college leaders, outlining the partnership agreement. The fourth organization (DC Prep, PrepNext) involves informal relationships with individual college staff members who take an active interest in their students and help in a variety of ways. The paper also briefly discusses the challenges faced by PrepNext and another organization (Capital Partners for Education) with developing partnerships. Drawing from the experiences of these organizations, the paper offers recommendations for community-based organizations interested in developing effective partnerships with colleges and universities. The recommendations encompass how to identify potential college partners and find someone to approach about partnering, initiating a conversation to explore the feasibility of a partnership, developing a proposal for how the partnership will work, and nurturing the partnership over time.
