Selection of Incident Commanders Is Done by the...?
Selection of Incident Commanders is done by the jurisdiction or organization with primary responsibility for the incident (the Authority Having Jurisdiction). The IC is chosen based on qualifications and experience, and command can be formally transferred to a more qualified person as the incident evolves.
The answer
In the Incident Command System (ICS), selection of Incident Commanders is done by the jurisdiction or organization with primary responsibility for the incident -- often called the Authority Having Jurisdiction (AHJ). The person chosen is the one with the qualifications, training, and experience appropriate to the size and complexity of the incident. On a small local event that may be a fire captain or police sergeant; on a large or expanding incident it may be a highly trained command-level officer.
The governing principle is jurisdictional authority: the agency legally responsible for the geographic area or the type of incident has the right and duty to designate who leads the response. This keeps command grounded in accountable, existing authority rather than assigned by an arbitrary role.
Why jurisdictional authority is the basis
ICS is built to work across every level of government and the private sector, so it cannot rely on a fixed chain of individuals. Instead it relies on who owns the problem. A wildfire on federal land, a hazmat spill in a city, and a school emergency each have a different responsible authority -- and each authority selects an IC qualified for that specific incident. Because qualification matters more than rank, ICS explicitly allows the initial IC to hand off leadership as conditions change.
Transfer of command
A closely related, heavily tested concept is transfer of command. The first qualified responder on scene establishes command and becomes the initial Incident Commander. As the incident grows -- or when a more qualified or more appropriate person arrives -- command is formally transferred. Transfer of command must include a command briefing that passes along the current situation, objectives, resources, and safety concerns so nothing is lost in the handoff. This process is why the selection of an IC is not a one-time event: the responsible jurisdiction ensures the right qualified person holds command throughout.
Why the other options are wrong
Common distractors on this question name specific ICS roles, none of which selects the IC:
- Planning Section Chief -- wrong. Planning collects and evaluates information and prepares the Incident Action Plan. It works for the IC and has no authority to appoint one.
- Public Information Officer -- wrong. The PIO handles media and public information. It is a Command Staff support role, not an appointing authority.
- Operations Section Chief -- wrong. Operations directs tactical resources. Like Planning, it is subordinate to the IC and cannot select command.
- The Incident Commander (self-selecting) -- wrong. The IC does not appoint themselves out of nowhere; they hold the position because the responsible jurisdiction designated them (or because they were the first qualified responder and later transfer command per that jurisdiction's system).
The bigger picture
The takeaway for NIMS/ICS exams: authority flows from the responsible jurisdiction, and competence -- not rank or a particular section -- determines who commands. Pair this with two related facts often tested alongside it. First, an incident normally has one Incident Commander to preserve unity of command. Second, when multiple agencies share responsibility (for example, fire, police, and a state agency at one large incident), they may establish Unified Command, in which those agencies jointly set objectives while still functioning under a single coordinated ICS structure.

Frequently asked
Who appoints the Incident Commander in ICS?
The jurisdiction or organization with primary responsibility for the incident -- the Authority Having Jurisdiction -- appoints the Incident Commander. The choice is based on the person's qualifications and experience relative to the incident.
What qualifications does an Incident Commander need?
An IC must have the training, experience, and qualifications appropriate to the size and complexity of the specific incident. That is why command may transfer to a more qualified person as an incident grows.
What is transfer of command in ICS?
Transfer of command is the formal process of moving Incident Commander responsibility from one person to another, for example when a more qualified responder arrives. It requires a command briefing that conveys the current situation, objectives, and resources.
Can there be more than one Incident Commander?
Under a single command structure, an incident has only one Incident Commander to maintain unity of command. When multiple agencies share jurisdiction, they may form a Unified Command, jointly setting objectives within one ICS structure.
What is Unified Command?
Unified Command is an ICS application used when several agencies or jurisdictions share responsibility for an incident. Their representatives work together to set common objectives and strategies while operating under a single, coordinated command structure.
