The standards reflected in the checklists are established national policy requirements. The checklists reflect the agency standard for operations and performance in each area of review and are not arbitrary standards set by the review team. These checklists are used on all of the Fire and Aviation Directorate (FAD) National Preparedness Reviews to maintain a consistent level of review nationwide. The individual states can request individual items of interest be added to the checklists used in their state review, but these additions must not undermine any established national policy requirements outlined in the standard checklist.
