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.

The WWC does not certify, endorse, or recommend any programs, policies, or practices. The WWC rates a study based on an objective, critical review of the study’s ability to make a claim about an intervention. The rating is separate from the findings. For example, a high-quality study may show that an intervention has negative effects.
