REACH of Louisville conducted long-term program evaluation for Kentucky IMPACT, an innovative system of care for children’s mental health. The program grew out of the need for more community-based intervention with children who experience serious emotional and behavioral disabilities. The program’s history parallels (and in many ways has led) a national movement toward transforming systems of care for these children and their families. By the year 2000, Kentucky IMPACT had served over 12,000 children, providing a broad range of interventions in an integrated fashion, with strong emphasis on service coordination and collaboration among child-serving organizations and agencies.
