Agencies responsible for implementing public programs are increasingly seeking out evidence-based practices to determine services and activities that generate better outcomes at lower cost. PPRI’s program evaluation research services help state agencies test the efficacy of new policies or alternative approaches to service delivery. PPRI utilizes data for quantifying and better understanding the potentially positive, and sometimes negative, effects of applying new or different approaches. Program evaluation research is a tool for policymakers and administrators to achieve innovation, efficiency, effectiveness, transparency, and public accountability.
