SECTION 1: ICS Overview and NIMS Management Characteristics
(Q1-Q15)
ICS Principles | NIMS Components | 14 NIMS Management Characteristics | Whole Community Approach
Q1. Which statement best describes the Incident Command System (ICS)?
A. A standardized approach to incident management applicable to all hazards, across all levels of
government, and across all functional disciplines [CORRECT]
B. A system used only by federal agencies during major disasters declared under the Stafford Act
C. A military command structure adapted for use only by law enforcement during active threats
D. A regional framework used exclusively by fire services for wildland incidents
Correct Answer: A
Rationale:
ICS is a standardized, on-scene, all-hazards incident management concept. NIMS doctrine defines ICS as
applicable across all levels of government, all functional disciplines (fire, law enforcement, EMS, public works, public
health), and all hazards, whether natural, technological, or human-caused. ICS is NOT limited to federal
declarations, military/law-enforcement use, or fire service wildland response. Option B misstates the scope by tying
ICS to Stafford Act declarations; options C and D incorrectly restrict ICS to single disciplines. The Whole Community
approach reinforced in NIMS 2017 expects ICS use by every jurisdiction and organization that responds to incidents.
Q2. Which of the following is NOT one of the 14 NIMS Management Characteristics?
A. Common Terminology
B. Manageable Span of Control
C. Centralized Decision-Making Authority [CORRECT]
D. Integrated Communications
Correct Answer: C
Rationale:
There are 14 NIMS Management Characteristics, and Centralized Decision-Making Authority is not among them.
The 14 include Common Terminology, Modular Organization, Management by Objectives, Incident Action Planning,
Manageable Span of Control, Incident Facilities and Locations, Comprehensive Resource Management, Integrated
Communications, Establishment and Transfer of Command, Unified Command, Chain of Command and Unity of
Command, Accountability, Dispatch/Deployment, and Information and Intelligence Management. ICS relies on
modular organization and unity of command, not centralized authority at a single position. Options A, B, and D are
genuine NIMS characteristics. Test-taking tip: memorize all 14; questions of this type are common on IS-100.c.
Q3. During a multi-agency response to a hazardous materials spill, responders from different
jurisdictions are using the same terms to describe organizational functions, incident facilities, and
resource descriptions. Which NIMS Management Characteristic does this best illustrate?
A. Information and Intelligence Management
B. Common Terminology [CORRECT]
C. Modular Organization
D. Management by Objectives
Correct Answer: B
Rationale:

Common Terminology requires that incident personnel use standard titles and a common vocabulary for
organizational functions, incident facilities, and resource descriptions. This prevents confusion when multiple
jurisdictions and disciplines work together. Information and Intelligence Management (A) deals with collecting and
analyzing incident information. Modular Organization (C) refers to the top-down scalable structure developed by the
Incident Commander. Management by Objectives (D) involves establishing measurable incident objectives that drive
the IAP. The scenario specifically describes shared vocabulary, so B is correct.
Q4. An Incident Commander is managing a growing incident and decides to expand the organization
by delegating responsibility for Operations, Logistics, Planning, and Finance/Administration to
General Staff Section Chiefs. Which NIMS Management Characteristic is being demonstrated?
A. Manageable Span of Control
B. Modular Organization [CORRECT]
C. Accountability
D. Dispatch/Deployment
Correct Answer: B
Rationale:
Modular Organization allows the ICS structure to develop in a top-down, modular fashion based on the size and
complexity of the incident. The Incident Commander establishes the organization by activating only those functional
positions and sections that are needed and deactivating them when no longer required. Manageable Span of Control
(A) governs the number of subordinates per supervisor (typically 3-7, with 5 as optimal). Accountability (C) involves
check-in, assignment tracking, and check-out. Dispatch/Deployment (D) governs how resources are ordered and
deployed. The scenario describes expanding the structure by activating Sections, which is Modular Organization.
Q5. Which NIMS Management Characteristic is demonstrated when the Incident Commander
establishes incident objectives that include strategies, tactics, tasks, and activities needed to
achieve the objectives?
A. Incident Action Planning
B. Management by Objectives [CORRECT]
C. Unified Command
D. Information and Intelligence Management
Correct Answer: B
Rationale:
Management by Objectives is the NIMS Management Characteristic that establishes a clear, measurable set of
incident objectives. It includes determining strategies, tactics, tasks, and activities needed to achieve the objectives,
which then drives the Incident Action Plan. Incident Action Planning (A) is related but specifically refers to the
process of developing written IAPs for each operational period. Unified Command (C) is when multiple
agencies/jurisdictions share command. Information and Intelligence Management (D) addresses collecting,
analyzing, and sharing incident information. The question describes the objective-setting process itself, which is
Management by Objectives.
Q6. A supervisor in an Operations Division is responsible for directing seven direct reports.
According to NIMS guidance on span of control, what is the recommended range?
A. 1 to 3 resources per supervisor
B. 3 to 7 resources per supervisor, with 5 being optimal [CORRECT]
C. 8 to 12 resources per supervisor
D. There is no recommended range; the supervisor decides

The 14 include Common Terminology, Modular Organization, Management by Objectives, Incident Action Planning,
Manageable Span of Control, Incident Facilities and Locations, Comprehensive Resource Management, Integrated
Communications, Establishment and Transfer of Command, Unified Command, Chain of Command and Unity of
