As the research arm of the U.S. Department of Education, IES provides rigorous and relevant evidence on which to ground education practice and policy and shares this information broadly. By identifying what works, what doesn't, and why, they aim to improve educational outcomes for all students, particularly those at risk of failure.

Their mission is to stimulate evidence-driven discourse on vital issues facing Chicago's public schools among all school staff, civic leaders, parents, students, and community activists.

The What Works Clearinghouse (WWC) was established in 2002 as an initiative of the Institute for Education Sciences (IES) at the U.S. Department of Education. The WWC is administered by the National Center for Education Evaluation within IES. The WWC identifies studies that provide credible and reliable evidence of the effectiveness of a given practice, program, or policy (referred to as “interventions”), and disseminates summary information and reports on the WWC website. With over 700 publications available and more than 6,000 reviewed studies in the online searchable database, the WWC aims to inform researchers, educators, and policymakers as they work toward improving education for students.
