The What Works Clearinghouse (WWC) is an initiative of the U.S. Department of Education's Institute of Education Sciences, and aims to:
- produce user-friendly practice guides for educators that address instructional challenges with research-based recommendations for schools and classrooms
- Assess the rigor of research evidence on the effectiveness of interventions (programs, products, practices, and policies), giving educators the tools to make informed decisions;
- Develop and implement standards for reviewing and synthesizing education research
-Provide 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.
While WWC publications are not the only source of evidence-based practice,
they have been developed via guidelines and criteria which are of current importance to the U.S. Department of Education
You can also locate articles and documents that address evidence-based practice by using keyword terms "evidence based" or "research based" in ERIC search statements and adding the Publication type limiter Reports-Research.
