Differential response (DR), also referred to as alternative response (AR), family assessment response (FAR), or multiple track response, was developed to incorporate family-centered, strengths-based practices into child protective services (CPS), primarily by diverting lower risk families into an assessment track rather than requiring the traditional CPS investigation. Since the program's inception, researchers have conducted several large evaluation studies of DR programs, and a large body of research and program literature has been published touting the success and benefits of DR. In response to significant concerns about the clarity and consistency of DR program models and the validity and generalizability of its associated research, the authors undertook a comprehensive, three-pronged evaluation to provide guidance in shaping the ongoing development of DR programs. This report summarizes the methodology, findings, conclusions, and recommendations from the review.
