In 2008, the Fostering Connections to Success and Increasing Adoptions Act gave states the option to extend the age of eligibility for federally funded foster care to 21. Twenty-five states and the District of Columbia have extended or are in the process of extending federally funded foster care with a safe, stable, and developmentally appropriate place to live. There are gaps in our knowledge of best practices for housing young adults in extended care, the housing options currently available to those young adults, and how those options vary across and within states. This brief begins to address these knowledge gaps by gathering information form a purposive sample of officials from public child welfare agencies in states that have extended federally funded foster care to age 21 and a group of stakeholders who attended a convening on the topic. The brief also highlights suggestions for future research.
