Description: The Terrorist Radicalization Assessment Protocol-18 (TRAP-18) is a validated structured professional judgment instrument for risk of lone actor targeted attacks. This 1.5-hour seminar will introduce attendees to the 18 indicators of the TRAP-18 and some of the exciting validation studies that have been completed to date. Threat assessment teams investigate these cases online and on the ground; however, political unrest and the COVID-19 pandemic have made these tasks much more difficult. The TRAP-18 helps teams prioritize which cases pose high risk and need active management, and which cases are low risk and need only passive monitoring. Such decisions are critical for practice, and the TRAP-18 is the only scientifically validated terrorist threat instrument that supports such operational choices.

This 1.5-hour free training is a brief introduction to the development of the TRAP-18 and its intended uses. Professionals who wish to use the TRAP-18 in practice should attend Dr. Reid Meloy’s comprehensive TRAP-18 On Demand Training (
