This comprehensive review of policies and programs designed to support youth transitioning out of foster care spans all 50 states and the District of Columbia. As part of the review, Chapin Hall administered a web-based survey of state independent living services coordinators to collect up-to-date information about their state's policies and programs. The survey questions cover a number of domains including: conditions under which foster youth can remain in care after turning 18; provision of independent living and transition services; opportunities for youth to reenter care; and use of state dollars to supplement federal funds from the Chafee Foster Care Independence Program. A number of online resources including state independent living program websites, the National Child Welfare Resource Center for Youth Development's State-by-State Fact Pages, and the Transition from Foster Care to Adulthood Wiki were also reviewed. The study was commissioned by the Washington State Institute for Public Policy (WSIPP). (Eleven appendices are included: (1) Survey instrument; (2) Number of current foster youth ages 17 and older by age in years; (3) Definitions of supervised independent living placement options; (4) Age until which foster youth can remain in care and circumstances under which they can remain; (5) Maintaining court jurisdiction when young people remain in foster care beyond the age of majority; (6) Eligibility for Chafee-funded services; (7) Eligibility for supervised independent living; (8) Eligibility for Medicaid or other health care coverage; (9) Housing assistance for former foster youth; (10) Circumstances under which former foster youth can re-enter care; and (11) Use of state funds and other policies or programs designed to support transitioning foster youth.
