Multiple outlets note that “lockdown” and “active shooter” drills are often grouped together, but they differ in how they look and how they affect children. The distinction matters for children’s safety and well-being because each practice involves different actions, messaging, and expectations during an emergency response.
The Conversation and Phys.org describe how preparedness activities have become a routine part of some schools’ back-to-school processes, despite the discomfort they can cause. Phys.org ties the broader trend to changes following major school shooting incidents, including the 1999 mass shooting at Columbine High School in Jefferson County, Colorado, which helped drive the later development and wider adoption of school safety drill practices. While the outlets do not focus on a specific new incident in the provided text, both emphasize that clearer separation and understanding of drill types are important for how students experience them and for the overall goal of preparedness.
Overall, the differing emphasis across the sources is primarily about classification and implementation: one focuses on the practical and psychological differences between drill formats, while the other provides historical context for why such drills became widespread.
