The What Works Clearinghouse: Looking Back on 2018
Established in 2002, The What Works Clearinghouse (WWC) is an initiative of the Institute of Education Sciences within the U.S. Department of Education (USED) and led by several firms with expertise in education, research methodology, and dissemination of education research. In 2018, the WWC offered online group design training users to become a WWC-certified reviewer and developed tutorials providing information about the USED's evidence definitions used by grant programs. A web-based study review guide tool was also created for authors. Over 300 studies were added to its Reviews of Individual Studies database, and research relevant to charter schools were highlighted.
