OIG recommends that the Office of U.S. Foreign Assistance Resources enforce evaluation policies by developing and implementing an oversight plan to verify that bureaus and offices that are administering foreign assistance funding are implementing and adhering to the Foreign Aid Transparency and Accountability Act of 2016, the Foreign Affairs Manual (18 FAM 301.4), and the corresponding Guidance for the Design, Monitoring and Evaluation Policy at the Department of State, January 2018. This plan should include, at a minimum, a requirement to verify that definitions of “programs” and “large programs” are consistent with the FAM and a requirement to verify that Bureau Evaluation Plans are developed and implemented in accordance with existing guidance and by the established deadlines.
