lockdown drill
Shelter-in-place practice
A lockdown drill is a practice exercise in which a building's occupants—typically students and staff at a school—rehearse emergency procedures for an active threat such as a shooter.
Participants secure doors, move away from windows, and remain quiet until an all-clear signal.
The school conducts lockdown drills twice a year.
The term reflects the grim reality of mass shootings in American institutions.
