Established in 2002, the What Works Clearinghouse (WWC) is a central and trusted source of scientific evidence for what works in education.
An initiative of the U.S. Department of Education's Institute of Education Sciences, the WWC:
- Produces user-friendly practice guides for educators that address instructional challenges with research-based recommendations for schools and classrooms;
- Assesses the rigor of research evidence on the effectiveness of interventions (programs, products, practices, and policies), giving educators the tools to make informed decisions;
- Develops and implements standards for reviewing and synthesizing education research; and
- Provides a public and easily accessible registry of education evaluation researchers to assist schools, school districts, and program developers with designing and carrying out rigorous evaluations.

Learn more about the WWC by reading the “What Works for Practitioners” and “Bringing Answers to Educators” guides in the document library. The WWC is administered by the U.S. Department of Education's (ED) Institute of Education Sciences through a contract with Mathematica Policy Research, Inc., a nationally recognized leader in education research and in rigorous reviews of scientific evidence.
As a partner site of the WWC, Doing What Works (DWW), led by the ED Office of Planning, Evaluation & Policy Development (OPEPD), helps educators identify and make use of effective teaching practices. Much of the DWW website content is based on information from the WWC in addition to other types of information and materials from IES.
