The Preventing Sex Trafficking and Strengthening Families Act of 2014 (SFA) is our country’s most recent piece of federal legislation impacting child welfare systems, with the potential to touch almost every area of child welfare policy and practice. The law holds particular promise for older foster youth who are often forgotten by the child welfare system. Without good enforcement mechanisms, however, even the best law has little chance of success. This is especially true of laws that impact vulnerable children. Luckily, there are many ways to hold systems accountable while states implement the SFA.
