Opportunity Works was a three-year effort led by Jobs for the Future to help opportunity youth--young people ages 16 to 24 who are not in school or meaningfully employed--access postsecondary and career pathways. Based on the Back on Track framework, seven cities across the country undertook collective impact approaches with diverse partners to provide supportive, enhanced preparation and postsecondary/career bridging for eligible young people, with a particular focus on young men of color. A quasi-experimental evaluation conducted by the Urban Institute in three Opportunity Works sites found large, consistent, positive effects on participants' postsecondary enrollment and increased connection with either education or employment about one year after program entry. Specifically, Opportunity Works participants were twice as likely to enroll in college and 25 percent more likely to be in either education or employment. Postsecondary results were even greater for young men of color, who were nearly six times as likely to enroll in college. This report also includes insights and lessons from qualitative field research. [This report was written with Adaeze Okoli and Natalie Spievack.]
