All HSEEP compliant entities conduct a T&EPW each calendar year in which they develop a Multi-year Training and Exercise Plan, which includes: (1) The entities' training and exercise priorities (based on an overarching strategy and previous improvement plans). (2) The capabilities from the TCL that the entity will train for and exercise against. (3) A multi-year training and exercise schedule which: (3.a) Reflects the training activities which will take place prior to an exercise, allowing exercises to serve as a true validation of previous training. (3.b) Reflects all exercises in which the entity participates. (3.c) Employs a "building-block approach" in which training and exercise activities gradually escalate in complexity. (4) A new or updated Multi-year Training and Exercise Plan must be finalized and implemented within 60 days of the T&EPW. (5) All scheduled exercises must be entered into the National Exercise Schedule (NEXS) System. The Multi-Year Training and Exercise Plan must be updated on an annual basis (or as necessary) to reflect schedule changes. (FEMA, About HSEEP, 2008)
