HSEEP is a national program developed by the U.S. Department of Homeland Security's Federal Emergency Management Agency. Exercises funded through Federal agencies require HSEEP compliance.
HSEEP is a capabilities- and performance-based exercise program that includes a cycle, mix, and range of exercise activities of varying degrees of complexity and interaction. The purpose of HSEEP is to build self-sustaining exercise programs and provide a standardized policy, methodology, and terminology for designing, developing, conducting, evaluating and improving all exercises.
