This brief describes the American Public Human Services Association (APHSA) and Chapin Hall's partnership to build momentum and consensus for child welfare system transformation by bringing together human services agency leadership, experts with lived experience, and national partner organizations to advance cross-sector recommendations for shared responsibility across public health and human services to prevent child maltreatment and unnecessary involvement with the child welfare system. This collective vision for child and family well-being--driven by communities and enacted through state and federal policy and investments--is a key opportunity to strengthen the nation's approach to prevention. This approach expands equitable access to economic and concrete supports as protective factors and promotes family stability, integrity, and well-being at the individual and population level.
