what works clearing house

The What Works Clearinghouse (WWC) is an initiative of the U.S. Department of Educations Institute of Education Sciences (IES) that was created in 2002 to be a decision-making resource by helping the education community locate and recognize credible and reliable evidence. The WWC provides trusted information about education effectiveness and highlights interventions with research evidence that meet WWC standards. The WWC is a leading federal source of evidence-based information about education programs, policies, and practices. The WWC reviews research on various education programs and policies and provides reports on their effectiveness based on the research evidence. The WWC also has a set of standards for evaluating studies that have met eligibility screens.
