This report presents the results of the CalYOUTH Survey of Young Adults' Child Welfare Workers, a survey of case workers supervising youth in extended foster care who are participating in the CalYOUTH Youth Survey. The report shares the county child welfare workers' views on how these young people are faring with the transition to adulthood, as well as their preparedness and service needs in a wide range of areas. The report also shares workers' perceptions of the availability and helpfulness of services within their county, their perceptions of court personnel's supportiveness of extended care, their satisfaction with collaboration with other systems of potential support for youth, and their views of challenges to effective implementation of extended foster care in California. The survey results highlight areas of progress and opportunities for continued improvement as California continues its development of foster care for young adults.
