What Works Clearinghouse (WWC)

The What Works Clearinghouse (WWC) is a resource provided by the U.S. Department of Education that reviews and summarizes research on educational programs and practices. Its goal is to help educators, policymakers, and parents make informed decisions by providing evidence on what strategies are proven effective in improving student learning. The WWC evaluates studies to identify those that meet high standards of scientific rigor, offering clear summaries and ratings of the strength of the evidence for various educational interventions.
