Abstract
Child welfare, education, health, juvenile justice, and mental health systems have simultaneously initiated movements to reform services to troubled children during the past ten years. Recently, these agencies have shown increased interest in bringing their change efforts together for a more unified system of care. This paper describes essential components of systems of care and interagency collaboration. A case illustration describes a setting in which special service providers in schools, particularly special education administrators and school psychologists, played major roles in the conceptualization and implementation interagency collaboration for a system of care.
