This brief describes a study that looked at how state-operated extended foster care (EFFC) programs are providing young adults in EFFC with safe, stable, and developmentally appropriate housing. The authors focused on the states with the largest number of young people participating in EFFC programs: California, Connecticut, Illinois, Indiana, Michigan, Minnesota, New York, Oregon, and Pennsylvania. They conducted interviews with representatives from eight of the nine state’s public child welfare agencies to gather information about housing options for EFFC programs. From these conversations, the authors suggest future research questions related to housing options and supportive services that lead to the best outcomes for young adults who participate in EFFC programs.
