Increasing college attainment offers tremendous promise for increasing social mobility, tackling poverty, and reducing racial and income inequality, aspirations that are more vital than ever as the devastating impact of the pandemic has fallen disproportionately on people of color. Yet for too many policymakers and practitioners, the path to growing our college completion rates for all students has been elusive. The U.S. has made steady progress in increasing college-going rates, but its success in increasing the proportion of Americans with college degrees has been more measured and inequitable. Completion rates are lower among Black and Latino students than white students, and among community college students than those attending four-year institutions. As a result, the very students for whom a college degree could be a life-changing event are still left out of the college earnings premium. Over the past decade, innovative leaders have pioneered a new approach to raising postsecondary completion rates that goes beyond financial support: comprehensive student success initiatives (CASS). This report provides a sample of findings from studies of CASS programs, CASS impact and potential by the numbers, and recommendations for state policymakers.
