HSEEP Prevention Exercises (formerly known as HSEEP Volume V) provides an overview of prevention exercises, information on the Terrorism Prevention Exercise Program (TPEP), and guidance and instruction on how to plan, conduct, and evaluate a prevention-focused exercise. The TPEP used a series of pilot exercises to develop and validate prevention exercise tools and methodologies. Now that these have been developed and published in HSEEP Prevention Exercises, the intent is to push them out for use by the HSEEP community. This document is intended to be used by Federal, State, local, and tribal preparedness officials and exercise planners who are interested in prevention-focused exercises. HSEEP Prevention Exercises presumes that standard HSEEP methodology as outlined in HSEEP Volumes I-III will be followed, and therefore focuses only on those areas in which prevention exercise tools and methodologies diverge from or supplement standard HSEEP guidance
