This is a one-hour lesson in which the dispatcher will listen to three 9-1-1 calls where callers report an active shooter at a college campus. Dispatchers will use a computer to read through the lesson and learn best practices in interrogating callers reporting such an incident.  The lesson addresses the fact that campus shootings are a tragic reality and the calls in this lesson offer an excellent training opportunity for dispatchers. Further, it highlights the importance of being familiar with a campus and the buildings located there.  It examines the need to establish: the caller’s exact location inside the building by confirming the caller's room number; the exact location of the shooter; and the type of weapon(s). It addresses how to remain professional while controlling an interview and considering scene safety.
