This guide was developed as a refresher for ICS practitioners to aid in preparation for advanced training, exercises, or real-world events.

Recognizing that many responders may have lag time between completing ICS-100, ICS-200, and higher level system or position-specific training, EMSI has developed this short guide to better prepare responders for additional training. Such pre-course preparation aids and enhances the delivery of training by allowing instructors to more readily delve into the course specific materials without having to provide a refresher of fundamental ICS concepts. Condensing these concepts into a quick and easy-to-read format can additionally assist responders in reviewing key concepts before an exercise or real-world response, thereby improving their performance during the event.
