In partnership with the American Humane Association and the Institute of Applied Research, WRMA is implementing the National Quality Improvement Center on Differential Response in Child Protective Services (QIC-DR), awarded as a cooperative agreement by The Children's Bureau. During the initial phase, the QIC-DR has gathered and assessed existing differential response practice models, gaps and needs, and selected a research focus. The QIC-DR will then select research and demonstration project sites and will conduct a multi-year experimental-design evaluation.
