During the course of organizing a major deployment for TERT teams, both at the local mutual aid level, as well as out-of-state support in large disasters (both natural and man-made), the National Joint TERT Initiative (NJTI) developed a guidance document called the APCO/NENA ANSI 1.105.2-2015 Standard for TERT Deployment.
It is highly recommended that every TERT team facilitator become thoroughly familiar with the material contained in this guidance document.
