The Child Welfare Community Collaborations (CWCC) initiative is designed to mobilize communities to develop and evaluate multi-system collaboratives that address local barriers and provide a continuum of services to prevent child abuse and neglect. In 2018 and 2019, the Children’s Bureau awarded 5-year cooperative agreements to a total of 13 states, non-profit organizations, and Native American tribal organizations. This Office of Planning, Research, and Evaluation brief provides a high-level description of each of the 13 CWCC projects and is one of a series of products the evaluation team will produce as part of the cross-site process evaluation. This brief contains a one-page description of each project, including its geographic catchment area, population of focus, key partners, prior experience with community-level collaboration, timeline, and local evaluation.
