ICS 203
Organization Assignment List
Purpose. The Organization Assignment List (ICS 203) provides ICS personnel with information on the units that are
currently activated and the names of personnel staffing each position/unit. It is used to complete the Incident
Organization Chart (ICS 207) which is posted on the Incident Command Post display. An actual organization will be
incident or event-specific. Not all positions need to be filled. Some blocks may contain more than one name. The size
of the organization is dependent on the magnitude of the incident, and can be expanded or contracted as necessary.
Preparation. The Resources Unit prepares and maintains this list under the direction of the Planning Section Chief.
Complete only the blocks for the positions that are being used for the incident. If a trainee is assigned to a position,
indicate this with a “T” in parentheses behind the name (e.g., “A. Smith (T)”).
Distribution. The ICS 203 is duplicated and attached to the Incident Objectives (ICS 202) and given to all recipients as
part of the Incident Action Plan (IAP). All completed original forms must be given to the Documentation Unit.
Notes:
• The ICS 203 serves as part of the IAP.
• If needed, more than one name can be put in each block by inserting a slash.
• If additional pages are needed, use a blank ICS 203 and repaginate as needed.
• ICS allows for organizational flexibility, so the Intelligence/Investigations Function can be embedded in several
different places within the organizational structure.
