The Best Evidence Encyclopedia is a free web site created by the Johns Hopkins University School of Education's Center for Data-Driven Reform in Education (CDDRE) under funding from the Institute of Education Sciences, U.S. Department of Education. It is intended to give educators and researchers fair and useful information about the strength of the evidence supporting a variety of programs available for students in grades K-12.
The organization promotes well-informed decision making by preparing, maintaining and disseminating systematic reviews in education, crime and justice, social welfare and international development.
The goal of the WWC is a resource for informed education decision-making. The WWC identifies evidence-based practice, program, or policy, and disseminates summary information on the WWC website.
