Since the late 1990s, the federal government has increased supports that promote college success for foster youth (Okpych, 2012), such as the $5,000 education and training voucher that foster youth can use each year toward college expenses. A key piece of federal legislation supporting foster youth is the 2008 Fostering Connections to Success and Increasing Adoptions Act, which gives states the option to extend the age limit of foster care up to youths' 21st birthday (Courtney, Dworsky, & Napolitano, 2013). Youth participating in extended foster care receive services past their 18th birthday that could impact their likelihood of going to college, such as subsidized housing, access to child welfare professionals, and other resources. In fact, enrolling in college and making satisfactory academic progress is one of the five eligibility criteria for participating in extended care. To date, little research has evaluated the impact of extended foster care on early college outcomes. The current study draws on a large sample of youth from administrative California child welfare records, including youth who were in care before and after California's extended foster care law (Assembly Bill 12, or AB12) was enacted. This memo estimates the impact that California's extended foster care law had on postsecondary education enrollment and persistence.
