Training and emergency exercises are fundamental components of a comprehensive school safety preparedness program and should incorporate many activities. These activities should blend direct instruction (training and walkthroughs) and experiential learning (drills and exercises) methods. This blended approach helps develop the knowledge and skills necessary for a school’s response to all hazards.

In an effort to increase positive student and staff outcomes following training and drills, Maryland enacted legislation, Maryland House Bill 416, 2024 Session (Chapter 182), that specifically prohibits schools from using techniques that simulate an active assailant scenario. These banned techniques include simulated gunfire, explosions, and individuals acting as intruders. Additional MCSS requirements were enacted within the bill, which have led to the development of the following resources and initiatives.
