This report examines the planning process for implementing California's Fostering Connections to Success Act, as well as the new law's early implementation. It is based on data collected from in-depth interviews with key informants who played a critical role in passage of the law, in implementation planning, or in early implementation at the county and state level and from focus groups with young people who stood to benefit directly from the legislation. Although extended foster care is likely to look different in different states, California's experience offers many lessons from which other states might learn.
