The current project investigated the efficacy of a train-the-trainer active shooter response
program that was used to provide patrol officers with the ability to resolve active shooters.
Specifically, the transfer of information from subject matter experts, to local trainers, to officers
at home agencies was examined, as well as the retention of declarative and procedural
knowledge. The train-the-trainer paradigm was found to be a viable method for active shooter
response training. Regarding skills, evaluating thresholds, and handling persons depreciated the
fastest and the data indicated those skills need retraining at least every six months.
