From OPRE: Many programs within the Administration for Children and Families work with fathers to promote economic self-sufficiency and social well-being for them and their families. As a part of that work, we also implement rigorous research and evaluation projects designed to improve our understanding of how best to serve those fathers. This brief describes research and evaluation projects related to the Responsible Fatherhood grant program and noncustodial parents, and other research related to fathers and fatherhood.
