The Family First Prevention Services Act of 2018 transforms federal child welfare financing streams to allow funding for services to families whose children may be at risk of entering foster care. The law aims to prevent unnecessary removal of children from their families by allowing federal funding for mental health services, substance use treatment, and in-home parenting skill training. Further, the law attempts to improve the well-being of children in foster care by discontinuing federal reimbursement when a child's placement in a congregate care setting is unnecessary. The law also provides for increased support for young people as they transition from foster care to adulthood.
