Support for the extended care provisions of the federal Fostering Connections to Success and Increasing Adoptions Act of 2008 was, to a large extent, based on the belief that allowing youth in foster care to remain in care past their 18th birthday would improve their outcomes as adults. Research following foster youth into adulthood has shown that they generally fare much worse than their age peers in terms of educational attainment, employment and earnings, homelessness and economic hardship, health and mental health, early pregnancy and parenting, victimization, and criminal justice system involvement. This brief provides an early look at the relationship between extended foster care and selected outcomes for youth transitioning to adulthood from care in California. Examining outcomes observed when young people participating in the California Youth Transitions to Adulthood Study (CalYOUTH) were nineteen years old, the authors find evidence that remaining in extended care is associated with a number of benefits for young adults.
