Emergency Preparedness Drills for Active and Mass Shootings in Schools

Purpose of Review

There is widespread use of emergency preparedness drills in public K-12 schools across the US, but considerable variability exists in the types of protocols used and how these practices are conducted. This review examines research into both “lockdown drills” and “active shooter drills” as it relates to their impact on participants across different outcomes and evaluations of their procedural integrity.

Recent Findings

A number of studies on lockdown drills yielded largely consistent findings about their impacts, whereas findings related to the effects of active shooter drills are less uniform. The research also demonstrated that lockdown drills, though not active shooter drills, can help participants build skill mastery to be able to successfully deploy the procedure.

Summary

Differences in how drills impact participants and whether they cultivate skill mastery are largely attributable to the type of drill being conducted. This review suggests that employing clearly defined drill procedures incorporating best practices, coupled with instructional training, can help schools prepare for emergencies without creating trauma for participants.
