In recent years, leaders of American cities have become progressively concerned about increasing the college-going and completion rate of their residents. Mayors and other community leaders in Memphis, Boston, Louisville, San Francisco and other cities have launched initiatives to increase college completion rates, mobilizing stakeholders from the education, non-profit, and corporate sectors to share responsibility for achieving these goals. To a large extent, efforts to increase college-going and completion rates have focused on making changes in K-12 and higher education systems to ensure that young people finish high school ready for college and complete degrees in a timely manner. But, today there is growing recognition of the important role that community-based organizations (CBOs) can play in supporting young people's postsecondary aspirations and success. This brief highlights research focused on the role and impact of community-based organizations in the college access and success movement and the implications of this research for improving practice. It also describes the experiences of one CBO in helping students access and succeed in college. CBOs play an important role in the education pathways for many students. A useful model for understanding these pathways and where CBOs can assist is the Insulated Education Pipeline, created by the Forum for Youth Investment. The pipeline illustrates the various ways community organizations provide support to young people along the education continuum from early childhood through postsecondary completion and successful entry into the workforce.
