College Promise programs--initiatives designed to guarantee tuition and fees for eligible students--have swept across the country, unlocking the opportunity of higher education for students in more than 200 communities across 44 states, including 16 statewide programs that have passed through legislation or executive orders. These forward-thinking institutions, cities, regions, and states are setting a powerful example in these efforts to expand access to higher education. The College Promise Campaign, Achieving the Dream, and Complete College America look forward to serving as a resource as education, business, government and philanthropy leaders work to build or refine College Promise programs in their communities and states. Focused attention on the purpose, design, and measurement of College Promise students and outcomes are essential to increasing the number of Americans with college degrees and certificates of purpose and value. The simple yet staggering truth is this: a high school education is no longer sufficient for advancement in the fast-growing, knowledge economy of the 21st century. In this policy brief, a menu of evidence-based strategies for institutions, communities, and states to incorporate into their Promise initiatives is offered, boosting student success and the ultimate likelihood of completion. The hope is that this report will inspire leaders to design high-quality College Promise programs that are intentionally "built for completion." The nation will need millions more well-prepared, career-ready graduates to increase and sustain economic prosperity, and well-designed Promise programs are a dynamic tool to help reach these goals.
