What is a lockdown?

A lockdown is a precautionary measure in response to a threat.  Lockdown drills are methods of practicing preparedness in the event of an intruder in the school or criminal activity in the surrounding community. 

A modified lockdown happens when there is no immediate danger to students and staff inside the school. It could be prompted by a potentially dangerous situation in the community near a school.  During a modified lockdown classes generally continue as normal but students and staff stay inside the building.

A full lockdown occurs when there is an immediate threat to the safety of students and staff.  During a full lockdown everyone in the school must stay in secure locations, remaining silent with all doors locked, lights off, and blackout shades dropped to cover classroom windows.

Lockdown procedures vary by state and school district.

Drop - Lock - Click




When a school faces an immediate threat posed by an intruder or an emergency situation outside the school that prevents evacuation, we recommend a lockdown procedure that includes the following key steps:

  • DROP window shades and secure them to block classroom views
  • LOCK all classroom doors
  • CLICK off all the lights

During a lockdown, everyone should move away from windows and doors. All students should remain together and not move around the room, keeping out of sight.  DO NOT respond to anyone at the door until the "all clear" is announced.

We strongly recommend that every school have a lockdown procedure in place and practice those steps regularly. It is critical to contact local law enforcement, emergency management agencies, and fire/rescue departments for assistance in developing a comprehensive crisis preparedness program.
