Active Threat Options Based Decisions

The A.L.I.C.E. Training Program

After the April 20, 1999, Columbine High School shooting in Colorado, a law enforcement officer named Greg Crane created the A.L.I.C.E. training program out of his desire to equip people with a better plan in case of an active threat event. It has become the accepted training response framework in the United States. The Wheaton Police Department recommends that all Wheaton area schools, businesses, and public services provide A.L.I.C.E training to its constituents to prepare for an active threat. Wheaton College will provide both in-person and online options for this training.

A.L.I.C.E. is a program that trains people to know their options if an active threat is encountered. The A.L.I.C.E. option(s) utilized in an emergency should match the situation; the options are not sequential steps.


A.L.I.C.E. definitions and descriptions

  • Alert - The first notification of danger.
