Office of Evaluation Sciences at GSA

Based at the General Services Administration (GSA), the Office of Evaluation Sciences (OES) is a team of interdisciplinary experts that works across the federal government to help agencies build and use evidence. OES provides government-wide expertise and support on leading practices for evidence-building and evaluation, and partners with federal agencies to answer priority questions using rapid and rigorous evaluation. 


To date, OES has completed over 70 randomized evaluations with dozens of agency partners. Our portfolio has spanned priority areas such as retirement security, reducing the cost of government operations, improving public health outcomes, and increasing educational opportunity.
