<p> A majority of active shooter incidents occur at the workplace (FBI, 2014), and the frequency of natural disasters is on the rise (Mileti, 1999). Many large agencies prepare employees through various response training approaches for such crises. TSA historically addressed training for all emergencies through a mandatory online all-hazards training, along with yearly evacuation drills. Following the Los Angeles International Airport (LAX) shooting on November 1, 2013, a mandatory active shooter web-based training was also assigned to every TSA employee. After completing both the all-hazards and active shooter web-based trainings courses, TSA employees had the option to participate in the training evaluation surveys. Analysis of the feedback from the online trainings informs both the acceptability of this training format, as well as future improvements for the web-based curriculum. This research highlights the suitability of providing important training to TSA officers online.</p>
