The Office of Evaluation Sciences (OES)
The Office of Evaluation Sciences (OES) is an interdisciplinary team that brings diverse
scientific expertise to Federal agencies and translates research insights into concrete
recommendations for how to improve Federal programs, policies, and operations. OES then
collaborates directly with agencies to implement, rigorously test, and evaluate the impact of
Based at the General Services Administration (GSA), OES supports GSA’s Office of
Government-wide Policy’s mission to serve agencies by helping them to use policies, evidence,
and analysis to drive efficiency, savings, and improved mission performance. At GSA, OES is
uniquely situated to deploy technical support to agencies across the Federal government,
provide an independent yet intragovernmental perspective, and develop standards for high-
quality rapid-cycle evaluations in the government environment. OES’ mission and operating
model involve engaging a wide variety of agencies to answer high-priority questions, often
developing iterative collaborations over multiple years to fill evidence gaps.
Since 2015, OES and the United States Agency for International Development (USAID) have
collaborated to apply insights from behavioral sciences and conduct rigorous, low-cost
evaluations on child and maternal health and infectious diseases programs around the world.
The goal of the collaborations is to identify cost-effective, evidence-based changes that can be
scaled for broader impact.
