What Works Clearinghouse Launches Registry of Randomized Controlled Trials

As a way to help advance the quality of educational research, the WWC Registry of Randomized Controlled Trials has assembled a substantial list of randomized controlled trials in education (RCTs) that are currently under way or have been completed. This online database offers researchers, evaluators, and others in the field one-stop access to search for these studies. Visitors may browse by title of the study, sponsor organization, study status, and target population. There is also detailed information about each study, including principal investigators, related publications, characteristics of study participants, and study outcomes.

The initial collection of RCTs populating the database are those funded by the Institute of Education Sciences, but the WWC is anticipating the addition of many more RCTs from education program developers, evaluators, researchers, and policy research organizations that sponsor and/or conduct randomized controlled trials of educational interventions.

If you are interested in submitting your RCTs for this registry, please visit to add to the database.
