A Secured Campus occurs when an outside event, threat near the building or an on campus incident that requires security actions to take place.  Secured Campus is a preventative response which rapidly enhances the level of security within the building.  In a Secured Campus, all exterior doors and main interior doors are locked, making it more difficult for an intruder to enter the building or gain access to students, but staff and students can continue with productive activities in a limited fashion.

The following definitions for Secured Campus are general definitions and apply to most incidents. However, since not all situations are the same, school administration may utilize the response most appropriate based on information available to them at the time of the incident.
