The Title IV-E Prevention Services Clearinghouse was established by the Administration for Children and Families (ACF) within the U.S. Department of Health and Human Services (HHS) to systematically review research on programs and services intended to provide enhanced support to children and families and prevent foster care placements. The Clearinghouse, developed in accordance with the Family First Prevention Services Act of 2018, will rate programs and services as promising, supported, and well-supported practices. These practices will include mental health and substance abuse prevention and treatment services and in-home parent skill-based programs, as well as kinship navigator services.
