This brief examines attitudes towards and knowledge about extended foster care in California, both from the viewpoint of young people themselves as well as caseworkers across the state. Three specific areas are examined: youths' motivation to participate in extended foster care and caseworker perceptions of their motivation; youths' knowledge of extended care and caseworker perceptions of their knowledge; and caseworker attitudes toward extended care. Both groups report similar reasons for youth to participate in extended foster care. Caseworkers report some concern that youth are not as knowledgeable as they should be about extended care. While the majority of youth were aware of their right to remain in foster care after turning 18, there was less clarity about some details of extended care. Caseworkers also report some ambivalence about extended foster care.
