NIMS ICS 300 Examination Blueprint
1. A large-scale hazardous materials spill has occurred at a
commercial rail yard, crossing multiple municipal boundaries and
requiring resources from several independent jurisdictions. The
local emergency management agencies decide to establish a
command structure where agencies share commanding authority
by working together to establish a common set of incident
objectives. Which Incident Command System (ICS) structure must
be implemented?
• Single Incident Commander
• Area Command
• Unified Command
• Multiagency Coordination Group (MAC Group)
Correct Answer Description: Unified Command is implemented
when an incident affects multiple jurisdictions or involves
multiple agencies with functional responsibility, allowing them to
manage the incident jointly without losing their individual legal
authority or accountability.
2. During an expanding wildland fire that has reached a Type 3
complexity level, the Incident Commander (IC) notes that the
number of resources reporting directly to the Command Staff has
exceeded a manageable span of control. To optimize operational
safety and efficiency, what is the recommended ratio of supervisor-
to-subordinates under NIMS guidelines?
• 1 supervisor to 15 subordinates
,• 1 supervisor to 10 subordinates
• 1 supervisor to 5 subordinates
• 1 supervisor to 2 subordinates
Correct Answer Description: NIMS identifies an optimal span of
control ratio as 1 supervisor to 5 subordinates, though a ratio of
1:3 to 1:7 is acceptable depending on the complexity and safety
hazards of the operational environment.
3. A flash flood has impacted a major metropolitan area, prompting
the activation of the local Emergency Operations Center (EOC). As
the incident transforms from an initial response to an expanding
operation, who retains the ultimate legal responsibility for overall
strategic, on-scene incident management activities?
• The Emergency Operations Center Director
• The State Governor’s Emergency Liaison
• The Incident Commander (or Unified Command)
• The Planning Section Chief
Correct Answer Description: On-scene command and
management are always the direct responsibility of the Incident
Commander or Unified Command, while the EOC focuses on
macro-level resource support, policy coordination, and tracking.
4. A train derailment involving toxic chemical tankers requires an
immediate, multi-day response. The Planning Section begins
drafting the formal document that outlines incident objectives,
operational tasks, safety messages, and communication protocols
for the upcoming work block. What is this mandatory document
called?
• Incident Status Summary (ICS Form 209)
• Incident Action Plan (IAP)
• Organizational Assignment List (ICS Form 203)
• Incident Briefing Form (ICS Form 201)
Correct Answer Description: The Incident Action Plan (IAP)
outlines the specific operational objectives and resource
assignments for a designated Operational Period, ensuring all
responding forces work toward unified goals.
,5. During a major structural collapse response at an industrial
facility, the Operations Section Chief divides the physical
geographic impact zone into three distinct sectors to better manage
on-scene task execution. In ICS nomenclature, what is the correct
term for an organizational element established to retain span of
control based strictly on geographical areas?
• Groups
• Branches
• Divisions
• Units
Correct Answer Description: Divisions are organizational
elements established to partition an incident geographically.
Groups, by contrast, are established to divide an incident into
specific functional areas of operation.
6. A multi-day biological outbreak response requires specialized
water testing, aerial tracking, and epidemiological analysis. The
Incident Commander establishes a dedicated unit within the
Planning Section to handle the collection, evaluation, and tracking
of environmental and scientific data. What is this component
called?
• Technical Specialists
• Air Operations Branch
• Compensation and Claims Unit
• Ground Support Unit
Correct Answer Description: Technical Specialists can be
assigned anywhere within the ICS structure where their expertise
is needed, but they are most frequently placed within the
Planning Section to support situational analysis.
7. An incident command structure is expanding rapidly during a
localized civil unrest response. The Logistics Section Chief needs to
set up a centralized location that houses primary support
resources, such as food, medical supplies, sleeping quarters, and
equipment repair, to service field personnel. What is the standard
ICS term for this support hub?
• Incident Command Post (ICP)
, • Base
• Staging Area
• Camp
Correct Answer Description: An incident Base is the location
where primary logistics and support functions are coordinated.
There is only one Base per incident, whereas multiple Camps may
be established to provide regionalized support.
8. A Unified Command structure is managing a massive maritime oil
spill. The representative from the state environmental protection
agency disagrees with the local fire chief regarding a specific
booming strategy. How must disputes or disagreements be
resolved within a Unified Command structure?
• The local jurisdiction's representative makes the final decision
unilaterally.
• The issue is automatically deferred to a federal court arbiter.
• The members must coordinate to achieve a consensus
decision based on common objectives.
• The section chiefs vote, and majority rule dictates the final
operational policy.
Correct Answer Description: Unified Command requires a
cooperative process where all participating commanders must
achieve a consensus to execute operations. If consensus cannot be
reached, the agency with supreme jurisdictional authority over
that specific issue typically makes the final determination.
9. A Type 3 incident is underway involving an active shooter search
across a large forest reserve. The Incident Commander decides to
organize specialized tactical tracking teams, K9 elements, and off-
road vehicle units into an integrated group under a single
designated supervisor with a common communications link. What
is this specific resource configuration called?
• Single Resource Unit
• Task Force
• Strike Team
• Resource Pool
Correct Answer Description: A Strike Team consists of a set
