11 community colleges in New Jersey and two Historically Black Community Colleges (one in Alabama and one in Mississippi) joined the OnPath project, which had the goal to help community college students stay enrolled during the pandemic. OnPath facilitated a powerful combination of people and knowledge by bringing together college staff members with operational knowledge about what needs to change, evidence from rigorous MDRC research about what helps students persist in college, and facilitators from MDRC's Center for Applied Behavioral Science. Through a series of workshops, one-on-one coaching sessions, and evidence-based templates of messaging strategies, researchers collaborated with staff members to: (1) develop student outreach campaigns that simplified registration information, connected students to available financial aid, and encouraged continuous enrollment based on prior rigorous evidence about what works to encourage enrollment; and (2) design new student-centered strategies to improve student persistence during the pandemic. The messaging strategies were informed by best practices and research evidence from MDRC evaluations. These integrated approaches enabled colleges to implement new messaging campaigns to better address students' needs and begin to implement new policies to reduce barriers to student success.
