IS 100 introduces the Incident Command System (ICS) and provides the foundation for higher-level ICS training.  The course describes the history, features and principles, and organizational structure of ICS.  It also explains the relationship between the ICS system and the National Incident Management System (NIMS).

IS 100 training is required by NIMS responders, and employees involved in emergency planning, emergency response, or any disaster or emergency recovery efforts.
