I/ITSEC is sponsored by the National Training and Simulation Association (NTSA), an affiliate of the National Defense Industrial Association (NDIA)
The Interservice/Industry Training, Simulation and Education Conference (I/ITSEC) is the world's largest modeling, simulation, and training conference. It is always held near the beginning of December in Orlando, Florida, USA, and it consists of peer-reviewed paper presentations, tutorials, special events, professional workshops, a commercial exhibit hall, a serious games competition, and STEM events for teachers and secondary students.
I/ITSEC is organized by the National Training and Simulation Association (NTSA), which promotes international and interdisciplinary cooperation within the fields of modeling and simulation (M&S), training, education, analysis, and related disciplines at this annual meeting. The NTSA is an affiliate subsidiary of the National Defense Industrial Association (NDIA). Hence, I/ITSEC also emphasizes themes related to defense and security.
