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.
Founded in 2015, the Learning Policy Institute (LPI) conducts and communicates independent, high-quality research to improve education policy and practice. LPI seeks to advance evidence-based policies at the local, state, and federal levels that support empowering and equitable learning for each and every child. Nonprofit and nonpartisan, LPI works with policymakers, researchers, educators, community groups, and others to strengthen the education system from preschool through college and career readiness.
