College promise programs are spreading throughout this United States. These programs fund tuition and/or fees for eligible students who are actively progressing toward earning postsecondary certificates and undergraduate degrees. While existing college promise programs have varying designs, each one appears to be seeking continuous and long-term financial sustainability. The existing programs appear to be aimed toward ensuring that the promise of college tuition and fees can be fulfilled for future generations of students. Towards that end, ETS and the College Promise Campaign convened the "Designing Sustainable Funding for College Promise Initiatives" conference on June 2 and 3, 2016, for the primary purpose of reviewing and refining five models. This report contains the five papers that the appointed design teams presented: (1) College Promise Models and College Savings Accounts: How College Savings Can Bolster the Early Financial Aid Commitment (William Elliott and Andrea Levere); (2) Designing Sustainable Funding for College Promise Initiatives: State-Funded Model Group (Randy Boyd and Teresa Lubbers); (3) Privately Funded Models and Public--Private Partnerships to Promote College Promise Initiatives (Lezli Baskerville and Hugh Fitzpatrick); (4) The Federal Government's Role in Promoting Promise Programs and Their Goals (Sandy Baum and Bill Hansen); and (5) Designing Sustainable Funding for College Promise Initiatives: Outcomes-Based Financing Models (Gloria Gong, Steve Goldberg, Audrey Peek, Kevin James, and Miguel Palacios).
