These documents summarize Chapin Hall’s evaluation of the Community Partnerships for Protecting Children (CPPC) initiative as implemented in four urban communities—Cedar Rapids, Iowa; Jacksonville, Florida; Louisville, Kentucky; and St. Louis, Missouri. Initially funded by the Edna McConnell Clark Foundation in 1996, CPPC sought to reduce the incidence of child abuse and neglect and increase children’s safety through a combination of practice reforms within the child welfare system, collaborative efforts among public service providers and community-based service agencies, and efforts to build a collective commitment to children and families on the part of community residents. Chapin Hall’s evaluation, implemented between 2000 and 2004, focused on determining the initiative’s impacts with respect to child safety and other key outcomes and garnering from this experience useful information in shaping ongoing reform efforts. Data collection efforts included repeated assessments of families exposed to specific practice reforms within child welfare; repeated surveys of local agency managers and direct service workers regarding collaboration levels, service quality and service availability; and an analysis of state child welfare administrative data at the individual and community levels. The study reports findings on subsequent child abuse reports and placement among those families subject to the practice reform as well as community-wide trends in these and other related indicators. The study also identified specific areas in which the current CPPC failed to provide sufficient direction to insure strong and consistent implementation.
