What Works Clearinghouse

Evidence for What Works in Education

We review the research on the different programs, products, practices, and policies in education.

Then, by focusing on the results from high-quality research, we try to answer the question “What works in education?”

Our goal is to provide educators with the information they need to make evidence-based decisions.
