The What Works Clearinghouse (WWC) was established in 2002 as an initiative of the Institute for Education Sciences (IES) at the U.S. Department of Education. The WWC is administered by the National Center for Education Evaluation within IES.
The goal of the WWC is to be a resource for informed education decision making. To reach this goal, the WWC identifies studies that provide credible and reliable evidence of the effectiveness of a given practice, program, or policy (referred to as “interventions”), and disseminates summary information and reports on the WWC website. With over 700 publications available and more than 6,000 reviewed studies in the online searchable database, the WWC aims to inform researchers, educators, and policymakers as they work toward improving education for students.
For nearly a decade, the WWC has been a central and trusted source of scientific evidence for what works in education to improve student outcomes. What does that mean?
The work of the WWC is conducted under a set of contracts held by several leading firms with expertise in education
and research methodology, and managed by IES on behalf of the U.S. Department of Education.
