How often should communities test and review their emergency plans according to the NRF?

The correct choice emphasizes the importance of regularly testing and reviewing emergency plans to ensure they remain current and effective. The National Response Framework (NRF) advocates for communities to engage in a continuous process of evaluation and improvement of their emergency management strategies. This includes conducting regular drills, exercises, and updates to plans based on lessons learned from past incidents or changes in the community's risk profile.

By reviewing and testing plans regularly, communities can identify gaps, refine their procedures, and prepare more effectively for various types of emergencies. This proactive approach helps to enhance the resilience and overall readiness of the community in the face of potential disasters. A one-time review or infrequent assessments would not adequately address the evolving nature of threats or the needs of the community, making regular evaluations essential for effective emergency management.
