Purpose: The Emergency Preparedness Exercise Evaluation Toolkit is designed to help emergency response planners evaluate the given public health systems performance during exercises. Toolkit Description: This toolkit is an evaluation instrument that collects performance data when observing public health and health emergency response activities in exercises. The toolkit is designed to aid in the documentation of performance measures based on an AHS checklist of actions. Doing so allows users to objectively document the performance of specific actions while simultaneously subjectively rating the quality of said performance. The toolkit includes training materials, a database of exercise performance measures, as well as an online analytical tool that generates performance reports during exercise. It is organized into the following eight sections: 1. Evaluation Methodology 2. Exercise Basics 3. Facilitator Guidelines 4. Evaluator Guidelines 5. Exercise Evaluation Tools 6. Emergency Preparedness Exercise Evaluation Database 7. After Action Reports 8. References Once the exercise is completed, and the data is entered, the toolkit generates a graphical output of the level of performance. Who should use it?:The toolkit is designed to be used by public health officials, hospital leaders, EMS, emergency managers and fire officials at health departments, community settings, and emergency management meetings. Benefits: Evaluating the performance of public health agencies during exercises gives responders the opportunity to assess their current capabilities and identify areas for improvement. By improving on the areas identified in the Emergency Preparedness Exercise Evaluation Toolkit, public health systems can increase their capabilities in planning for and responding to a vast array of situations.
