What approach to threat assessment does LCPS use?

Posted by:

LCPS conducts threat assessments in accordance with the Comprehensive School Threat Assessment Guidelines, an evidence-based model developed by Dr. Dewey Cornell and colleagues at the University of Virginia. These guidelines were initially published as Guidelines for Responding to Student Threats of Violence and have been widely adopted by schools in Virginia and other states.  LCPS Policy 8290 outlines the requirements for conducting a threat assessment.
