What Works Clearinghouse

The Registry of Randomized Controlled Trials (RCTs) is an online database of completed and in-progress RCTs in education. This resource is designed to help schools, school districts, and educational program developers identify research regarding the effectiveness of educational interventions.

The information in the Registry of Randomized Controlled Trials is supplied solely by the researchers themselves. Neither the What Works Clearinghouse (WWC) nor the U.S. Department of Education endorses any individuals or organizations listed in the registries. The WWC does not verify the accuracy of the information submitted by the researchers, nor does it assess their qualifications. The WWC does not provide confidentiality of any information provided to the registries.
