The WWC’s Database of Study Findings provides data resulting from WWC reviews for every study that meets standards and is included in a quick review, single study review, or intervention report, as well as studies that have been reviewed for Department grant competitions. It provides comprehensive data at the outcome level, a finer level of observation than any other WWC database.

The WWC has reviewed over 10,000 studies since its inception in 2002. This list of these 10,000+ studies is available in our Reviewed Studies Database. This list can be searched by keyword, topic, rating, and publication type, and it can be accessed by anyone.

Our list of publications and reviews contains all practice guides, single study reviews, intervention reports, and quick reviews released by the What Works Clearinghouse. This list can be searched by keyword, topic, or publication type.

The WWC trains and certifies its reviewers to ensure that all reviews produced are accurate representations of whether studies meet standards. The certified reviewers database enables anyone to search certified reviewers by type (individual or organization) or certification (group design or single case design). The reviewers in the database have agreed to the public posting of their information and can be contacted directly for non-WWC related review activities.
