What happens to youth in foster care when they turn 18? Many face unprecedented challenges like homelessness, lack of financial resources, difficulty accessing educational opportunities, and unemployment. In this issue brief, The American Youth Policy Forum (AYPF) document these challenges and opportunities in three distinct yet overlapping areas of need: (1) Sustainable Social Capital; (2) Permanency Supports; and (3) Postsecondary Opportunities. For each area of need, the authors define the challenges youth face and identify promising programs and policies that are in place to help them transition from foster care to a healthy, successful adult life.
