Effective exercise design, development and implementation is critical to building disaster preparedness capacity for medical emergency responders. This course highlights the role of exercises in the preparedness system. Plans, training, and certification alone fail to verify capabilities. Effective exercises validate plans, equipment operations, personnel skills, and training. This is accomplished through the establishment of exercise objectives, critical task, and criteria for acceptable performance. This course equips participants with the knowledge, skills, resources, and best practices for designing, implementing, and evaluating effective exercises to ensure continuous improvement. ASG will share its methods and best practices from conducting over 2,000 exercises.
