IES is the nation's premier source for research, evaluation and statistics that can help educators, policymakers and stakeholders improve outcomes for all students.
About this Site
The Institute of Education Sciences is committed to supporting states, districts, schools and institutions of higher education in their use of evidence-based practices to improve outcomes for all learners, especially those that education systems have historically underserved.
This site curates evidence, tools, and other materials from a wide range of sources—including but not limited to the U.S. Department of Education—that may be useful to partners as they undertake that critical work.
Importantly, the level of evidence underpinning the practices listed here varies. In virtually every case, more evidence is needed to better understand which practices are effective, for whom, and under what conditions.
Explore IES What Works Clearinghouse Resources
The What Works Clearinghouse reviews existing research to provide educators with the information they need to make evidence-based decisions. WWC Practice Guides present specific recommendations on how to best address challenges in classrooms and schools, based on reviews of the research, the experiences of practitioners, and the opinions of panels of nationally-recognized experts.
