Education decisionmakers require access to the best evidence about the effectiveness of
education practices, products, programs, and policies. It can be difficult, time-consuming, and
costly for decisionmakers, however, to access and draw conclusions from relevant studies about
the effectiveness of these interventions. The What Works Clearinghouse (WWC) addresses the
need for credible, succinct information by identifying existing research on education
interventions, assessing the quality of this research, and summarizing and disseminating the
evidence from studies that meet WWC standards.
