Incident Command System
The entire catalog of FEMA ICS online training is available at http://training.fema.gov/IS/crslist.aspx. Much is available online but the advanced courses (ICS 300 and 400) are only available in a classroom setting. These are offered several times a year at the Snohomish County DEM and the Washington State Emergency Management Division.
King County Emergency Management offers a similar schedule of courses available in the Puget Sound area.
