The Coalition for Evidence-Based Policy is a nonprofit, nonpartisan organization that seeks to increase government effectiveness through the use of rigorous evidence about "what works." The Coalition administers an expert review process to identify social programs meeting the Congressional "Top Tier" evidence standard: "well-designed randomized controlled trials [showing] sizeable, sustained effects on important ... outcomes" (e.g., Public Laws 110-161 and 111-8). The initiative has been reviewed favorably by the Government Accountability Office (GAO), and has had an important impact on federal legislation and policy.
