911 Dispatcher/Operator Exam — Questions and Answers

Question 1: During an active shooter event, a person calls 911 whispering from a locked office. They state they are safe but can hear gunshots in the distance. What is the most important piece of information to obtain from this caller?

The specific location of the shooter, if known. (Correct answer)
A description of the caller's injuries.
The caller's name and phone number.
The number of people hiding with the caller.

Correct answer: The specific location of the shooter, if known.

While all information is valuable, the shooter's location is the most critical piece of intelligence for responding law enforcement. This information allows officers to move directly toward the threat and neutralize it, which is the primary objective in an active shooter situation.

Question 2: What is the primary purpose of an operator repeating critical information, such as an address or license plate number, back to the caller?

To calm the caller by demonstrating that their information is being taken seriously.
To stall for time while waiting for units to be dispatched to the scene.
To create a clear, official voice recording of the information for potential legal proceedings.
To verify that the operator heard and recorded the information correctly, allowing the caller to make corrections. (Correct answer)

Correct answer: To verify that the operator heard and recorded the information correctly, allowing the caller to make corrections.

The main goal of this standard procedure, known as 'read-back' or 'echoing,' is to ensure accuracy. It confirms the operator has correctly understood the details and gives the caller an immediate opportunity to correct any errors before responders are sent with incorrect information.

Question 3: A caller reports a shooting with multiple victims and is also asking for directions to the hospital. What is the operator's first priority?

Provide directions so the caller can transport victims quickly
Transfer the call to the hospital's nurse line
Obtain location and dispatch EMS and police before providing any secondary assistance (Correct answer)
Ask the caller to count the victims before dispatching

Correct answer: Obtain location and dispatch EMS and police before providing any secondary assistance

Obtaining location and initiating dispatch is always the first action; secondary assistance like directions comes only after units are en route.

Question 4: A caller reports a domestic disturbance and mentions 'he has a knife.' At what point should this weapon information be relayed to responding officers?

Only if the caller repeats it a second time
When the officer arrives on scene and asks for an update
After the call has ended and a report is written
Immediately, as soon as the information is obtained (Correct answer)

Correct answer: Immediately, as soon as the information is obtained

Weapon information is a critical officer safety concern that must be transmitted to responders without delay.

Question 5: A caller reports a suspicious person and says: 'He's been standing outside for 20 minutes, he's wearing all black, and he keeps looking at the neighbor's house.' Which detail best justifies the call as suspicious?

He is wearing all black
The repeated focused attention on a specific property combined with prolonged presence (Correct answer)
He keeps looking at the neighbor's house
He has been there for 20 minutes

Correct answer: The repeated focused attention on a specific property combined with prolonged presence

The combination of prolonged presence and repeated focused attention on a specific property together create the suspicious behavior pattern, not either detail alone.

Question 6: What is the purpose of a 'jurisdiction boundary file' loaded into a CAD mapping system?

To automatically route calls to the correct agency based on the caller's geographic location (Correct answer)
To limit the number of units dispatched per zone
To display historical crime statistics by area
To block calls from outside the city

Correct answer: To automatically route calls to the correct agency based on the caller's geographic location

Jurisdiction boundary files allow CAD to automatically identify which agency is responsible for a given location and route the call accordingly.

Question 7: What is 'Next Generation 911' (NG911) designed to enable that traditional 911 systems cannot?

International 911 call routing
Faster dispatch of police-only units
Multimedia communications including text, video, and images to PSAPs (Correct answer)
Automatic dispatch without operator intervention

Correct answer: Multimedia communications including text, video, and images to PSAPs

NG911 upgrades the legacy phone-only infrastructure to an IP-based system supporting texts, photos, and video from callers.

Question 8: What is the significance of 'NENA' in the 911 industry?

National EMS Network Alliance — oversees ambulance dispatch protocols
National Enforcement and Notification Authority — regulates police dispatch
National Emergency Number Association — the standards body for 911 systems and training (Correct answer)
Network Emergency Notification Agency — manages federal alert systems

Correct answer: National Emergency Number Association — the standards body for 911 systems and training

NENA (National Emergency Number Association) develops standards, training guidelines, and best practices for 911 systems across the United States.

Question 9: Which of the following best describes 'ANI' in 911 call center operations?

Authorized Notification Input — a CAD data field
Automated Number Identification — the callback number transmitted with the call (Correct answer)
Average Notification Index — a call volume metric
Automatic Network Interface — the telephone switching system

Correct answer: Automated Number Identification — the callback number transmitted with the call

ANI delivers the caller's phone number to the dispatcher and is essential for callbacks if a call is disconnected.

Question 10: A caller provides a business name but cannot give a street address. What is the dispatcher's best next step?

Decline the call until an address is provided
Dispatch to the general area of the business district
Search the CAD database or a secondary resource for the business address while keeping the caller on the line (Correct answer)
Ask the caller to hang up and call back after finding the address

Correct answer: Search the CAD database or a secondary resource for the business address while keeping the caller on the line

Using available database tools to locate a business address while maintaining caller contact speeds dispatch without losing the caller.

Question 11: What does the term 'CAD' stand for in 911 dispatching?

Central Alert Dispatch
Coordinated Agency Directory
Computer-Aided Dispatch (Correct answer)
Call Activity Database

Correct answer: Computer-Aided Dispatch

CAD (Computer-Aided Dispatch) is the software system dispatchers use to log, track, and manage emergency incidents.

Question 12: Why is phonetic alphabet (NATO) used by 911 dispatchers when communicating with field units?

To keep communications private from the public
It is required by federal law for all radio transmissions
To reduce the speed of transmissions and allow units to write down information
To ensure letters are clearly understood over radio where similar-sounding letters can be confused (Correct answer)

Correct answer: To ensure letters are clearly understood over radio where similar-sounding letters can be confused

Letters like B, D, E, P, and T sound similar over radio, so the NATO phonetic alphabet (Alpha, Bravo, Charlie…) eliminates confusion in critical communications.

Question 13: Which approach best helps a dispatcher stay accurate when taking information from an extremely emotional caller?

Transcribe everything verbatim without interrupting, then sort it out after
Lower call volume and rely on instinct to fill gaps
Repeat back key data points aloud as they are spoken to confirm accuracy in real time (Correct answer)
Ask the caller to stop talking until they are calmer

Correct answer: Repeat back key data points aloud as they are spoken to confirm accuracy in real time

Real-time readback confirms critical details like addresses and phone numbers while keeping the caller engaged and somewhat focused.

Question 14: Which factor most significantly elevates a call's priority level?

Whether the caller is a repeat caller
The caller's tone of voice
Presence of weapons or immediate threat to life (Correct answer)
The neighborhood or area of the city

Correct answer: Presence of weapons or immediate threat to life

The presence of weapons or an immediate threat to life is the primary factor that escalates a call to the highest priority.

Question 15: An operator receives a 911 call where the caller speaks only Spanish and the operator does not speak Spanish. What is the correct procedure?

Use the agency's language interpretation service immediately (Correct answer)
Ask the caller to call back when they find an English speaker
Hang up and notify a supervisor
Transfer to a Spanish-speaking employee only

Correct answer: Use the agency's language interpretation service immediately

Most PSAPs have access to language interpretation services that must be engaged immediately to ensure the caller receives assistance.

Question 16: When a 911 dispatcher takes notes during a call, the notes should be:

Discarded after the call is closed in CAD
Objective, accurate, and legible enough to support the official CAD record (Correct answer)
Lengthy narrative descriptions of the dispatcher's interpretation
Written in personal shorthand that only the dispatcher can read

Correct answer: Objective, accurate, and legible enough to support the official CAD record

Dispatcher notes may be reviewed in legal proceedings and must therefore be objective, accurate, and professionally legible.

Question 17: When is it acceptable for a 911 dispatcher to share details of a call with friends or family?

Never — all call information is strictly confidential (Correct answer)
Only with explicit written supervisor permission
Only if the incident is already reported in the local news
Only after the incident has been officially closed

Correct answer: Never — all call information is strictly confidential

Dispatchers are legally and ethically bound by confidentiality requirements and must never share call details outside official channels.

Question 18: A caller describes chest pain radiating to the left arm in a 58-year-old male. What priority level should this call receive?

Low — chest pain is common and rarely serious
Hold for a supervisor to assess
High — potential cardiac emergency requiring immediate response (Correct answer)
Moderate — send units when available

Correct answer: High — potential cardiac emergency requiring immediate response

Chest pain with arm radiation in a middle-aged male are classic heart attack symptoms and demand an immediate Priority 1 response.

Question 19: A dispatcher receives a 911 call but hears only silence and no response after speaking. What is the correct action?

Hang up and await a callback
Announce your presence, attempt to elicit a response, and if unsuccessful, dispatch units to the traced address (Correct answer)
Transfer the call to the non-emergency line
Leave the line open indefinitely without dispatching

Correct answer: Announce your presence, attempt to elicit a response, and if unsuccessful, dispatch units to the traced address

Silent 911 calls may indicate a caller who is unable to speak, so dispatchers must announce themselves, listen for clues, and dispatch based on the traced address.

Question 20: A caller reports a structure fire with a person confirmed trapped inside. Which resource should be dispatched first?

Police only, to secure the scene
Animal control to clear the area
Utility crew to cut power
Fire department with simultaneous EMS staging (Correct answer)

Correct answer: Fire department with simultaneous EMS staging

Structure fires with entrapment require fire suppression and rescue as the primary response with EMS staged for victim treatment.

Question 21: You observe that calls involving juvenile suspects have a 40% higher rate of resolution without arrest when a youth officer responds. What inductive conclusion should influence dispatch decisions?

Requesting a youth officer for juvenile calls is likely to improve outcomes (Correct answer)
Juvenile calls should always result in arrest for consistency
Youth officers should never respond to juvenile calls alone
The 40% difference is not significant enough to change dispatch practices

Correct answer: Requesting a youth officer for juvenile calls is likely to improve outcomes

A 40% improvement in resolution rate is a strong inductive signal that youth officer involvement leads to better outcomes.

Question 22: A caller is reporting a vehicle accident while you are already dispatching a medical unit for another call. What is the best approach?

Continue coordinating the medical dispatch while gathering basic accident details from the new caller (Correct answer)
Place the first caller on hold and fully focus on the new call
Transfer the accident call to another dispatcher immediately
Ask the accident caller to call back in a few minutes

Correct answer: Continue coordinating the medical dispatch while gathering basic accident details from the new caller

Skilled 911 operators manage concurrent calls by gathering essential information from each while maintaining active dispatches.

Question 23: A caller reports a structure fire at '500 Oak Street' but there are two Oak Streets in the dispatch area. What should the dispatcher do first?

Flip a coin and document the decision
Ask the caller for a cross street, zip code, or other identifying detail to determine the correct location (Correct answer)
Dispatch to both Oak Streets simultaneously
Wait for the caller to provide more information without prompting

Correct answer: Ask the caller for a cross street, zip code, or other identifying detail to determine the correct location

When duplicate street names exist, the dispatcher must immediately gather clarifying information to avoid sending responders to the wrong location.

Question 24: A caller reports seeing someone break into a car. At the same time, another caller reports an armed robbery in progress. Which is dispatched first?

Both should be dispatched simultaneously with equal resources
The car break-in if the suspect is still on scene
The car break-in because property crime is more common
The armed robbery because it involves a weapon and active threat (Correct answer)

Correct answer: The armed robbery because it involves a weapon and active threat

An armed robbery in progress poses an immediate threat to human life, making it higher priority than a property crime.

Question 25: During a major incident, a dispatcher is told to 'go to talk-around.' What does this mean?

Use cell phones instead of radios temporarily
Switch to direct unit-to-unit radio communication without using the repeater (Correct answer)
Relay messages through a neighboring dispatch center
Broadcast on all channels simultaneously

Correct answer: Switch to direct unit-to-unit radio communication without using the repeater

Talk-around (also called direct or simplex mode) bypasses the repeater system and lets units communicate directly with each other on a shared frequency.

Question 26: In ICS radio communications, what is the role of the 'Communications Unit Leader' (COML)?

Monitor civilian scanner traffic during incidents
Plan, set up, and manage the communications system for an incident (Correct answer)
Handle all media and public information transmissions
Operate the primary dispatch console for the jurisdiction

Correct answer: Plan, set up, and manage the communications system for an incident

The COML is responsible for planning and managing the tactical communications system for an incident, including frequency assignments and equipment.

Question 27: Which sentence is written with the greatest clarity for a dispatch log?

Caller reports a physical altercation at 4th Ave and Main St involving two adult males. (Correct answer)
Caller said something about a fight somewhere near downtown.
There was a fight downtown, I think, according to what the caller said maybe.
Fight reported, downtown area, details unclear.

Correct answer: Caller reports a physical altercation at 4th Ave and Main St involving two adult males.

An effective dispatch log entry includes specific location, nature of incident, and subject description without vague qualifiers.

Question 28: What does it mean for a dispatcher to maintain 'situational awareness' during a complex incident?

Being physically present at the incident scene
Monitoring national weather alerts while dispatching
Continuously tracking the status of all active units, calls, and resources relevant to an ongoing incident (Correct answer)
Memorizing the entire radio log from the previous shift

Correct answer: Continuously tracking the status of all active units, calls, and resources relevant to an ongoing incident

Situational awareness in dispatch means continuously updating one's mental picture of all active resources, units, and incidents to make informed decisions.

Question 29: All medical emergencies require an ambulance. A caller reports chest pain and difficulty breathing. What do you deduce?

The caller should drive themselves to the hospital
The caller needs police assistance first
An ambulance is required (Correct answer)
Fire department should respond alone

Correct answer: An ambulance is required

Since all medical emergencies require an ambulance and chest pain with difficulty breathing is a medical emergency, an ambulance is required.

Question 30: Which cardinal direction does a street running left-to-right typically represent on a standard North-up map?

East–West (Correct answer)
Northeast–Southwest
North–South
It depends on the scale

Correct answer: East–West

On a North-up map, horizontal (left-to-right) streets run East–West, while vertical streets run North–South.

Question 31: A written policy states: 'Dispatchers must document the reason for any deviation from standard protocol.' A dispatcher skips a required verification step due to call volume. What should they do?

Omit the deviation since it was minor and situational
Ask a coworker to backfill the log entry after the shift
Document the deviation and the reason (high call volume) in the incident log (Correct answer)
Report the deviation only if a complaint is filed

Correct answer: Document the deviation and the reason (high call volume) in the incident log

Policy requires documenting any deviation and its reason, which protects both the dispatcher and the agency and enables process review.

Question 32: Two callers report the same incident from different perspectives — one says it is a fight, the other says it is a shooting. Which account should drive the priority?

The first caller's account since they called first
The more serious account (shooting) until units confirm otherwise (Correct answer)
Average the two accounts and assign a medium priority
Wait for a third caller to break the tie

Correct answer: The more serious account (shooting) until units confirm otherwise

When conflicting reports differ in severity, the more dangerous scenario must drive the priority to protect lives and officer safety.

Question 33: Which question is the most effective way for a dispatcher to clarify a caller's unclear statement?

'Could you please be more specific about absolutely everything?'
'Are you sure about what you saw?'
'Why didn't you call sooner?'
'When you say he threatened you, what exactly did he say or do?' (Correct answer)

Correct answer: 'When you say he threatened you, what exactly did he say or do?'

Focused, open-ended clarifying questions targeting the specific ambiguity extract useful information without overwhelming or alienating the caller.

Question 34: An operator recognizes the voice of a frequent caller known for reporting non-existent events. The caller now reports seeing thick, black smoke coming from a neighbor's house. What is the operator's most appropriate response?

Require the caller to provide a callback number for a supervisor to verify before dispatching.
Treat the report as a genuine emergency and dispatch the fire department per standard protocol. (Correct answer)
Advise the caller that misusing the 911 system is a crime and end the call.
Make a note of the call but do not dispatch units based on the caller's unreliable history.

Correct answer: Treat the report as a genuine emergency and dispatch the fire department per standard protocol.

An operator has a 'duty to act' on any report of a potential emergency. The caller's history does not negate the possibility that this report is legitimate. A report of smoke from a structure must always be taken seriously as a potential threat to life and property. Failing to dispatch would be a dereliction of duty and could have catastrophic consequences and create liability.

Question 35: A caller reports a structure fire but then goes silent. What should the 911 operator do first?

Only dispatch if the caller confirms the address
Hang up and wait for a callback
Transfer the call to the fire department directly
Continue attempting to communicate while dispatching fire units (Correct answer)

Correct answer: Continue attempting to communicate while dispatching fire units

Operators should dispatch on the available information and keep trying to communicate, as the caller may be incapacitated or fleeing.

Question 36: A caller reports an infant under one year old appears unconscious and is not breathing. How should the operator's CPR instructions differ from adult CPR?

Use full hands and the same compression ratio as adult CPR
Use only one finger for compressions and give no rescue breaths
Use two fingers for compressions and give small gentle puffs of air (Correct answer)
Instruct the caller to perform compressions only, no breaths for infants

Correct answer: Use two fingers for compressions and give small gentle puffs of air

For infants, operators should instruct two-finger compressions and small puffs of air to account for the infant's smaller size and lung capacity.

Question 37: Which of the following scenarios requires a dispatcher to use a 'hot transfer' to a PSAP in another jurisdiction?

The dispatcher is too busy to handle the call
The caller is speaking a foreign language
A caller asks about local parking laws
An incident location falls outside the receiving PSAP's service area (Correct answer)

Correct answer: An incident location falls outside the receiving PSAP's service area

A hot transfer (live transfer with the caller still connected) is used when an incident falls in another jurisdiction's service area so no information is lost.

Question 38: Which of the following BEST describes the risk of cognitive overload for a 911 dispatcher?

Using outdated CAD software that loads slowly
Handling too many easy calls in a row
Working too many overtime shifts without sufficient pay
Exceeding the brain's capacity to process multiple simultaneous inputs, leading to errors (Correct answer)

Correct answer: Exceeding the brain's capacity to process multiple simultaneous inputs, leading to errors

Cognitive overload occurs when the mental demands of simultaneous tasks exceed a dispatcher's processing capacity, increasing the likelihood of critical errors.

Question 39: When multitasking during a high-stress call, what is the most common type of data entry error an operator should be vigilant about?

Misspelling the caller's last name.
Transposing numbers in an address or license plate. (Correct answer)
Incorrectly logging the time of the call.
Forgetting to enter the call-taker's own ID number.

Correct answer: Transposing numbers in an address or license plate.

Transposition errors (swapping the order of numbers or letters) are common under pressure and can have significant consequences, such as sending responders to the wrong location or identifying the wrong vehicle. While all errors should be avoided, transposition of critical numbers is a frequent and high-impact mistake.

Question 40: A caller is reporting a suspicious vehicle and states the license plate is '7-Boy-Adam-Nora-9-1-Victor'. The connection has static. Based on standard phonetic alphabet comprehension, which of the following should be entered into the system?

7BAN91V (Correct answer)
7BAK91P
7PAV91B
7DAN91V

Correct answer: 7BAN91V

This question tests the ability to accurately recall and transcribe information provided using the standard law enforcement phonetic alphabet. 'Boy' stands for B, 'Adam' for A, 'Nora' for N, and 'Victor' for V.

Question 41: A dispatcher hears two units transmitting simultaneously causing a 'double' or 'co-channel interference.' What is the best immediate action?

Ignore it and wait for one unit to finish
Switch all units to an alternate channel permanently
Ask one unit to retransmit and request the other to wait (Correct answer)
Request both units reduce transmitter power

Correct answer: Ask one unit to retransmit and request the other to wait

The dispatcher should prompt one unit to retransmit while the other stands by, resolving the conflict and ensuring both messages are received.

Question 42: A caller is whispering and says there is an intruder in the house. What is the best dispatcher response?

Tell the caller to go to a neighbor's house before help arrives
Place the caller on hold while you contact police
Dispatch law enforcement immediately and ask yes/no questions to avoid alerting the intruder (Correct answer)
Ask the caller to speak up so you can hear them clearly

Correct answer: Dispatch law enforcement immediately and ask yes/no questions to avoid alerting the intruder

When a caller cannot speak safely, dispatchers should use yes/no questions and dispatch units immediately to avoid endangering the caller.

Question 43: What is the purpose of a grid coordinate system used in dispatch mapping?

To rank response priority of calls
To calculate caller wait times
To identify the nearest hospital automatically
To provide a standardized alphanumeric location reference for any point on the map (Correct answer)

Correct answer: To provide a standardized alphanumeric location reference for any point on the map

Grid coordinates provide a quick, standardized way to pinpoint any location on a dispatch map using alphanumeric references.

Question 44: During a mass casualty incident, a dispatcher's role includes:

Transferring all incoming calls to a federal emergency line
Ceasing all non-related calls until the incident is resolved
Coordinating multiple units, activating mutual aid, and maintaining communication between all responding agencies (Correct answer)
Responding to the scene to assist with triage

Correct answer: Coordinating multiple units, activating mutual aid, and maintaining communication between all responding agencies

During a mass casualty incident, the dispatcher is the communication hub — coordinating resources, requesting mutual aid, and keeping all agencies informed.

Question 45: A neighborhood has reported three catalytic converter thefts in two weeks, all occurring between 2–4 AM. What inductive conclusion helps dispatch prepare?

Catalytic converter thefts are random and unpredictable
The thefts will stop on their own
Increased patrols in that area between 2–4 AM are likely to deter or catch the thief (Correct answer)
The thefts are unrelated coincidences

Correct answer: Increased patrols in that area between 2–4 AM are likely to deter or catch the thief

A clear temporal pattern allows dispatch to recommend targeted patrol coverage during those hours.

Question 46: What distinguishes effective multitasking in dispatch from counterproductive multitasking?

Effective multitasking involves rapidly switching attention between tasks in a structured, priority-driven way (Correct answer)
Effective multitasking means doing two complex cognitive tasks simultaneously at full capacity
There is no meaningful difference — all multitasking degrades performance equally
Counterproductive multitasking means taking breaks between tasks

Correct answer: Effective multitasking involves rapidly switching attention between tasks in a structured, priority-driven way

Structured task-switching with clear priority rules preserves accuracy; attempting to split deep cognitive focus between two complex tasks simultaneously degrades both.

Question 47: What is the purpose of a 'call back' number obtained at the start of a 911 call?

To allow the dispatcher or responders to re-contact the caller if the call drops or more information is needed (Correct answer)
To bill the caller for emergency services
To forward the call to the correct dispatch center
To verify the caller's identity before dispatching

Correct answer: To allow the dispatcher or responders to re-contact the caller if the call drops or more information is needed

A callback number ensures continuity of communication if the connection is lost or responders need updated information.

Question 48: Examples of: Poor work ethics, low morale, and trouble focusing and staying focused

Physical stress
Emotional stress
Distress
Mental stress (Correct answer)

Correct answer: Mental stress

Poor work ethics, low morale, and difficulty focusing are classic indicators of mental stress. Unlike physical stress, which manifests in bodily symptoms, mental stress primarily impacts cognitive functions, emotional well-being, and professional performance. It can lead to decreased productivity, impaired decision-making, and a negative attitude in the workplace.

Question 49: A 911 operator must simultaneously listen to a caller, enter data into CAD, and monitor the radio for unit updates. This skill is best described as:

Sequential processing
Concurrent multitasking under stress (Correct answer)
Single-task focus
Passive monitoring

Correct answer: Concurrent multitasking under stress

911 dispatching requires true concurrent multitasking — processing multiple information streams simultaneously — which is a core tested competency.

Question 50: The cognitive ability to temporarily store, process, and manipulate information during a call, such as holding an address in your mind while hearing a suspect description, is known as:

Auditory processing
Working memory (Correct answer)
Situational awareness
Long-term memory

Correct answer: Working memory

Working memory is the specific cognitive system responsible for the temporary storage and manipulation of information required for complex tasks like listening, reasoning, and learning. It is essential for a dispatcher who must juggle multiple pieces of incoming information simultaneously before committing them to the CAD or long-term memory.

Question 51: A dispatcher's script says: 'Repeat the address back to the caller before ending the call.' A caller gives an address quickly and hangs up before the dispatcher can confirm. What should the dispatcher do?

Log the address as given and proceed without confirmation
Attempt to call back the number to verify the address (Correct answer)
Hold the call open until the caller returns
Dispatch to the nearest intersection and search the area

Correct answer: Attempt to call back the number to verify the address

Attempting a callback to verify is the best action to ensure accurate dispatch when confirmation wasn't possible during the call.

Question 52: An operator is handling a non-emergency call about a noise complaint. Simultaneously, they are monitoring radio traffic and notice a field unit has not checked in after a traffic stop within the expected timeframe. What is the operator's primary responsibility?

Send another unit to the officer's last known location without attempting radio contact first.
Continue with the noise complaint call while also trying to contact the officer on a secondary radio channel.
Politely conclude the noise complaint call and immediately initiate an officer status check via radio. (Correct answer)
Put the noise complaint caller on hold indefinitely to focus solely on the radio traffic.

Correct answer: Politely conclude the noise complaint call and immediately initiate an officer status check via radio.

Officer safety is the highest priority. The operator must multitask by recognizing the potential danger indicated by the missed status check, professionally disengaging from the lower-priority call, and immediately addressing the officer safety issue according to protocol. Juggling both tasks simultaneously or putting the caller on indefinite hold is inefficient and could compromise one or both situations.

Question 53: A caller reports they are traveling southbound on Route 1. They see the suspect's vehicle turn onto an intersecting street and head directly toward the setting sun. In which cardinal direction is the suspect now traveling?

West (Correct answer)
South
North
East

Correct answer: West

The sun rises in the east and sets in the west. If a vehicle is traveling directly toward the setting sun, it is heading in a westbound direction. The caller's own direction of travel is extra information not needed to solve the problem.

Question 54: Telecommunicators must be able to tell when a piece of information is inappropriate. All of the following are acceptable, but not:

Zero in on key words
Listen to the caller only, block out all background noises (Correct answer)
Not drawing premature conclusions
Ask follow-up/open-ended questions to gather information

Correct answer: Listen to the caller only, block out all background noises

While active listening is crucial for a telecommunicator, completely blocking out background noises is often impossible and can be counterproductive. Background sounds can provide vital contextual information about an emergency, such as the presence of sirens, screams, or specific environmental cues. A skilled telecommunicator learns to filter and interpret these sounds while focusing on the caller's voice, rather than ignoring them entirely.

Question 55: Which of the following terms best describes a road that is closed at one end and typically ends in a circular turnaround area?

An esplanade
A frontage road
A cul-de-sac (Correct answer)
An intersection

Correct answer: A cul-de-sac

A cul-de-sac is, by definition, a street or passage that is closed at one end. This is important for responders to know as it affects their route of approach and exit from a scene.

Question 56: A dispatcher is tracking three active units on the radio while taking a new 911 call about a domestic disturbance. Which mental tool is MOST useful for managing all tasks?

Repeating all radio traffic out loud to memorize it
Mentally 'chunking' unit statuses into a simple pattern to free capacity for the new call (Correct answer)
Ignoring the radio entirely until the new call is complete
Writing down every radio transmission word for word

Correct answer: Mentally 'chunking' unit statuses into a simple pattern to free capacity for the new call

Chunking — grouping unit statuses into a simplified mental model — reduces cognitive load so the dispatcher can handle the new call without losing situational awareness.

Question 57: A major freeway runs north-south through your city. An accident is reported in the northbound lanes at the 'Elm Street Overpass.' To provide the most accurate location information for responding units, which of the following pieces of geographic information is most important to verify and relay?

The speed limit on the freeway.
The direction of traffic on the Elm Street Overpass.
The nearest freeway on-ramp for responding units. (Correct answer)
The name of the freeway.

Correct answer: The nearest freeway on-ramp for responding units.

While the name of the freeway and the location of the overpass are essential, the most critical piece of actionable information for responding units is the best access point. Knowing the nearest on-ramp allows emergency vehicles to reach the scene via the most direct and efficient route, saving valuable time.

Question 58: What does it mean when a street address is listed as '100 block of Elm Street'?

The street has exactly 100 buildings
The address is unverifiable in the system
The address is exactly at number 100
The address is between house numbers 100 and 199 (Correct answer)

Correct answer: The address is between house numbers 100 and 199

The '100 block' refers to the range of addresses from 100 to 199 on that street.

Question 59: A caller says they are at a 'T-intersection.' What does this tell the dispatcher about the road layout?

Three roads meet at 60-degree angles
A road splits into two equal branches
One road ends and meets another road perpendicularly with no through-street (Correct answer)
Two one-way streets converge

Correct answer: One road ends and meets another road perpendicularly with no through-street

A T-intersection is where one road dead-ends into another, forming a 'T' shape with no road continuing straight through.

Question 60: A caller says 'someone broke into my car' but is whispering and says they are 'inside the house.' What should you deduce about the caller's situation?

The caller may be hiding from an intruder and is in immediate danger (Correct answer)
The caller is confused about the location of the break-in
The caller is exaggerating the incident
The call is a prank

Correct answer: The caller may be hiding from an intruder and is in immediate danger

Whispering while claiming to be inside suggests the caller may be hiding from a threat, indicating a more serious situation than a car break-in.

Question 61: What is the primary reason dispatchers are trained to keep callers on the line?

To record evidence for prosecution
To provide real-time updates to responders and guide the caller through pre-arrival instructions (Correct answer)
To ensure billing information is accurately captured
To prevent the caller from fleeing the scene

Correct answer: To provide real-time updates to responders and guide the caller through pre-arrival instructions

Keeping callers on the line allows dispatchers to relay evolving information to responders and deliver life-saving instructions before help arrives.

Question 62: A caller reports a hit-and-run collision; the victim is lying in the road and traffic is still moving. What simultaneous actions should the dispatcher take?

Send police only to document the hit-and-run
Send a tow truck first to remove the vehicle hazard
Wait for a witness to confirm injuries before dispatching
Dispatch EMS and police simultaneously and advise the caller to warn approaching drivers if safe to do so (Correct answer)

Correct answer: Dispatch EMS and police simultaneously and advise the caller to warn approaching drivers if safe to do so

A victim in an active roadway faces both medical emergency and ongoing vehicle hazard, requiring immediate simultaneous EMS and police dispatch.

Question 63: An elderly caller is reporting an emergency but cannot recall her address. What is the best way to help her identify her location?

Hang up and use ANI/ALI data to obtain the address from the system
Ask her to step outside and read the nearest street signs or house numbers (Correct answer)
Advise her to call a family member who might know the address
Ask for her phone number and search it in a phone book

Correct answer: Ask her to step outside and read the nearest street signs or house numbers

Asking the caller to look for visible address clues is faster and more reliable than solely depending on ANI/ALI, which may not be current.

Question 64: You receive a call from someone reporting their car was stolen from their driveway sometime overnight. While you are gathering information, a second call comes in reporting a multi-vehicle accident with injuries on the highway. What is the correct action to take?

Complete the stolen vehicle report in full before taking the second call to ensure accuracy.
Place the stolen vehicle caller on a brief hold to take the accident call, as it involves immediate risk to life. (Correct answer)
Tell the accident caller to hang up and call back after you finish the current call.
Attempt to handle both calls simultaneously by switching back and forth between them.

Correct answer: Place the stolen vehicle caller on a brief hold to take the accident call, as it involves immediate risk to life.

Call prioritization requires the 911 operator to address calls with an immediate threat to life first. The multi-vehicle accident with injuries is a higher priority than a stolen vehicle report where the event has already occurred and there is no ongoing danger. The operator should professionally and quickly pause the lower-priority call to handle the life-threatening emergency.

Question 65: You receive a call from someone reporting a strange odor in their basement, suspecting a gas leak. At the same time, another call comes in about a loud party next door. How should these be prioritized?

The loud party is a higher priority because it affects more people.
The suspected gas leak is a higher priority due to the potential for a fire or explosion. (Correct answer)
The loud party should be handled first to prevent escalation.
Both calls have the same priority level.

Correct answer: The suspected gas leak is a higher priority due to the potential for a fire or explosion.

A suspected gas leak is a high-priority call because it represents a significant threat to life and property due to the risk of explosion and fire. A noise complaint, while a valid call for service, does not carry the same level of immediate danger.

Question 66: A Telecommunicator may act in ways that reflect poorly on their professionalism, the organization they work for, or its members, including:

Laughing with a coworker
Taking frequent breaks and long lunches
Not knowing SOP's
Negative attitude, gossiping or making derogatory statements about the agency. (Correct answer)

Correct answer: Negative attitude, gossiping or making derogatory statements about the agency.

Professionalism for a telecommunicator involves maintaining a positive demeanor and upholding the agency's reputation. Negative attitudes, gossiping, or making derogatory statements undermine team morale, erode public trust, and reflect poorly on the entire organization. These actions demonstrate a lack of professional conduct and respect for the workplace and its mission.

Question 67: What is the purpose of 'incident priority codes' used by dispatch centers?

To assign liability in post-incident legal proceedings
To determine which calls are billed to the caller's insurance
To categorize calls for annual statistical reporting only
To rank the urgency of incidents so that resources are allocated to the most critical situations first (Correct answer)

Correct answer: To rank the urgency of incidents so that resources are allocated to the most critical situations first

Priority codes allow dispatchers to quickly rank incident urgency and ensure that life-threatening emergencies receive the fastest response.

Question 68: A caller describes an emergency near a freeway on-ramp. Which piece of information is MOST critical for dispatching accurately?

The direction of travel and nearest mile marker or cross street (Correct answer)
The number of lanes on the freeway
The speed limit on the freeway
The color of nearby buildings

Correct answer: The direction of travel and nearest mile marker or cross street

Direction of travel and the nearest mile marker or cross street precisely locate the caller on a multi-lane freeway.

Question 69: A caller is reporting a house fire. They provide the address, state that their elderly father is trapped on the second floor, describe the smoke color, and mention their cat is also missing, all within a few seconds. In terms of immediate memory recall for dispatching the fire department, which two pieces of information are the absolute highest priority?

The address and the trapped person. (Correct answer)
The color of the smoke and the missing cat.
The address and the color of the smoke.
The trapped person and the missing cat.

Correct answer: The address and the trapped person.

The two most critical factors for an emergency response are the location of the incident (the address) and any immediate life safety threats (a person trapped). This information must be recalled instantly and accurately to dispatch the correct resources and inform responding units of a known rescue situation.

Question 70: A caller reports a structure fire but says they are still inside the building. What is your FIRST priority?

Get the caller out of the building immediately (Correct answer)
Document the address accurately
Dispatch fire units
Ask about the number of floors

Correct answer: Get the caller out of the building immediately

Life safety is always the first priority, so directing the caller to evacuate takes precedence before gathering additional details.

Question 71: Which of the following scenarios would be classified as the highest priority for police response?

A domestic dispute where one party is threatening physical harm and has access to a weapon. (Correct answer)
A call about illegally parked vehicles blocking a driveway.
A report of shoplifting where the suspect fled the scene 10 minutes ago.
A request for a welfare check on a neighbor who hasn't been seen in a few days.

Correct answer: A domestic dispute where one party is threatening physical harm and has access to a weapon.

A domestic dispute with threats of violence and the presence of a weapon constitutes an immediate threat to life, making it a top-priority call for law enforcement. The other situations are of a lower priority as they do not involve an imminent danger of physical harm.

Question 72: A caller describes their location as the 'northeast corner' of an intersection. Which two streets form the northeast corner?

The street they are on and the street behind them
The street to their south and the street to their west
The street to their north and the street to their east (Correct answer)
The nearest major road and the highway

Correct answer: The street to their north and the street to their east

The northeast corner of an intersection is where the northward and eastward streets meet, placing the caller in that quadrant.

Question 73: On a dispatch map, what does a 'dead end' or 'cul-de-sac' notation mean for responding units?

Emergency vehicles are prohibited from using the road
The road is temporarily closed for construction
The road connects to an alley on the other side
There is only one way in and out, requiring careful positioning of units to avoid blocking egress (Correct answer)

Correct answer: There is only one way in and out, requiring careful positioning of units to avoid blocking egress

Dead ends and cul-de-sacs have only one entry/exit point, so units must position themselves to avoid blocking the only escape or additional response route.

Question 74: What is the primary reason 911 dispatchers practice typing drills and data entry exercises during training?

To satisfy equipment maintenance contracts with CAD vendors
To qualify for higher pay grades based on WPM scores
To meet federal regulatory minimums for computer use
To build the muscle memory needed to enter data accurately without diverting cognitive attention from callers (Correct answer)

Correct answer: To build the muscle memory needed to enter data accurately without diverting cognitive attention from callers

Typing drills build automaticity, allowing dispatchers to enter data without conscious effort, freeing cognitive resources for caller management.

Question 75: During an extended major incident, a dispatcher is managing unit tracking, caller updates, and CAD entries simultaneously. Which strategy BEST prevents critical information from being missed?

Prioritize radio traffic exclusively and defer all phone calls
Ask bystanders on the scene to manage communication
Use a systematic checklist or mental framework to cycle through all active tasks at regular intervals (Correct answer)
Rely entirely on memory to track all incoming information

Correct answer: Use a systematic checklist or mental framework to cycle through all active tasks at regular intervals

Systematic mental frameworks or checklists help dispatchers cycle through multiple simultaneous responsibilities without dropping critical information.

Question 76: What is the appropriate response when a unit fails to respond to three consecutive radio calls from dispatch?

Initiate a welfare check per agency protocol (Correct answer)
Mark the unit as out of service and move on
Switch the unit's channel assignment remotely
Assume the unit is on a call and stop trying

Correct answer: Initiate a welfare check per agency protocol

Failure to respond to repeated calls is a safety concern requiring a welfare check, as the officer may be in danger or incapacitated.

Question 77: A caller reports being lost and describes seeing a green highway sign that reads 'Exit 47 — Springfield 2 miles.' What can the dispatcher infer?

The caller is on Interstate 47
The caller is 47 miles from their destination
The caller is approximately 2 miles from the Springfield exit (Correct answer)
The caller is at mile marker 2

Correct answer: The caller is approximately 2 miles from the Springfield exit

Exit signs indicate the name of the next exit and the distance to it, placing the caller about 2 miles before the Springfield exit.

Question 78: A caller reports a neighbor using what appears to be a blowtorch near dry brush in high wind conditions. No fire is visible yet. How should this be classified?

Trespassing issue for police only
Noise complaint
Non-emergency — no fire is present
Fire hazard requiring fire department notification (Correct answer)

Correct answer: Fire hazard requiring fire department notification

The combination of an ignition source, dry brush, and high winds constitutes an imminent fire hazard warranting fire department response.

Question 79: A caller provides their address at the beginning of a call, then the connection becomes poor. You need to confirm the address before dispatching. What is the best approach?

Dispatch to the address you heard and hope it was correct
Disconnect and wait for them to call back on a better line
Use ALI (Automatic Location Identification) to confirm the address (Correct answer)
Ask the caller to repeat the entire call from the beginning

Correct answer: Use ALI (Automatic Location Identification) to confirm the address

ALI automatically captures the caller's location data, providing a reliable way to confirm or supplement a partially heard address.

Question 80: A dispatcher experiences a traumatic call involving a child fatality. What is the recommended next step for the dispatcher's well-being?

Immediately resign from the position
File a complaint with the caller for causing distress
Continue working the shift without acknowledgment to maintain professionalism
Utilize Critical Incident Stress Management (CISM) resources and speak with a peer support counselor (Correct answer)

Correct answer: Utilize Critical Incident Stress Management (CISM) resources and speak with a peer support counselor

CISM and peer support programs exist specifically for first responders, including dispatchers, to process traumatic incidents and prevent long-term psychological harm.

Question 81: A caller quickly provides a callback number and then the line goes silent. You only caught part of it: '555-0' before it cut out. What is the correct next step?

Use automatic number identification (ANI) to retrieve the full number (Correct answer)
Log what you have and move on
Wait for the caller to call again
Attempt to call back with different number combinations

Correct answer: Use automatic number identification (ANI) to retrieve the full number

ANI automatically captures the caller's number at the time of the call, making it the fastest way to retrieve a partial number.

Question 82: A 911 operator should obtain which piece of information as the absolute first priority when a medical call is received?

The patient's age and medical history
The caller's name and callback number
The exact location of the emergency (Correct answer)
Whether the patient has health insurance

Correct answer: The exact location of the emergency

The exact location of the emergency must be obtained first so EMS can be dispatched immediately, even if the call is later disconnected.

Question 83: Which of the following actions demonstrates proper radio discipline for a 911 dispatcher?

Acknowledging a unit's transmission with a brief, clear "copy" or "received" before proceeding. (Correct answer)
Holding the microphone key down for a few seconds before and after speaking to ensure the full message is sent.
Providing non-essential information and engaging in casual conversation to build rapport with units.
Speaking in a loud, high-pitched voice to ensure the transmission cuts through noise.

Correct answer: Acknowledging a unit's transmission with a brief, clear "copy" or "received" before proceeding.

Proper radio discipline prioritizes clear, concise, and professional communication. Acknowledging a transmission confirms the message was received and understood, which is essential for maintaining situational awareness and the flow of information. Speaking too loudly can cause distortion, non-essential chatter clogs the channel, and holding the key down excessively (dead air) prevents others from transmitting.

Question 84: A caller states they are at a location with no street address, only a GPS coordinate. What should the dispatcher do?

Enter the coordinates into the CAD mapping system or relay them to responders for GPS navigation (Correct answer)
Refuse the call until an address is provided
Ask the caller to find the nearest street sign
Automatically treat it as a non-emergency

Correct answer: Enter the coordinates into the CAD mapping system or relay them to responders for GPS navigation

GPS coordinates can be entered directly into CAD or provided to responders using GPS devices to locate the caller even without a traditional address.

Question 85: Which scenario represents the correct use of a 'priority hold' in emergency dispatch?

Transferring a high-priority call to another center during peak hours
Placing a caller on hold because the dispatcher is on a personal call
Temporarily holding a low-priority call so a dispatcher can concentrate on an active life-threat call (Correct answer)
Holding all calls during shift change to prevent overlap

Correct answer: Temporarily holding a low-priority call so a dispatcher can concentrate on an active life-threat call

A priority hold is a legitimate protocol that allows a dispatcher to focus on an active life-threat while briefly pausing a lower-priority caller.

Question 86: A caller describing a shooter says, 'He fired twice — no, maybe three times — then ran into the building on the left side of the parking lot.' What is the most critical piece of information for officer safety?

The uncertainty about the number of shots
The suspect entered a building (Correct answer)
The number of shots fired
The parking lot location

Correct answer: The suspect entered a building

The suspect entering a building is the highest officer safety concern as it changes the nature of the response from an outdoor to an indoor situation.

Question 87: What is the role of a Quality Assurance (QA) review process in a 911 communications center?

To discipline operators for every missed protocol step
To ensure CAD records are backed up daily
To reduce the number of 911 calls received per shift
To evaluate call handling for accuracy, protocol compliance, and training opportunities (Correct answer)

Correct answer: To evaluate call handling for accuracy, protocol compliance, and training opportunities

QA reviews help identify strengths and gaps in call handling to improve dispatcher performance and public safety outcomes.

Question 88: When a caller dials 911 but says nothing, what should the operator do?

Wait 60 seconds then disconnect
Immediately disconnect
Transfer to police only
Announce your presence, ask if help is needed, and stay on the line (Correct answer)

Correct answer: Announce your presence, ask if help is needed, and stay on the line

Silent calls may indicate an emergency where speaking is dangerous, so operators should announce themselves, listen for clues, and dispatch if uncertain.

Question 89: Which of the following is a key skill tested on most 911 dispatcher written exams?

Knowledge of criminal law statutes
Data entry accuracy under pressure (Correct answer)
Advanced medical diagnosis
Proficiency in a second language

Correct answer: Data entry accuracy under pressure

Accurate and fast data entry is critical for dispatchers because errors in incident logs or addresses can delay or misdirect response units.

Question 90: A 911 caller is giving you information rapidly and you cannot keep up with data entry. What should you do?

Let the caller keep talking and try to catch up later
Put the caller on hold until you finish typing
Politely ask the caller to slow down so you can accurately record the information (Correct answer)
Only enter the information you can catch and skip the rest

Correct answer: Politely ask the caller to slow down so you can accurately record the information

Accurate data entry is essential in emergencies, and it is appropriate to ask callers to slow down to ensure correct information is recorded.

Question 91: A caller reports a minor fender-bender with no injuries while simultaneously another caller reports a person collapsed and unresponsive. Which call receives the highest priority?

The fender-bender, as traffic hazards affect more people
Both calls receive equal priority
The first call received takes priority regardless of nature
The unresponsive person, as it is a life-threatening medical emergency (Correct answer)

Correct answer: The unresponsive person, as it is a life-threatening medical emergency

An unresponsive person represents an immediate life threat and always outranks property damage incidents with no injuries.

Question 92: A caller describes a medical emergency: 'He collapsed, he's breathing but unconscious, and he has a MedicAlert bracelet that says diabetic.' Which detail should trigger the most immediate action in your dispatch notes?

He has a MedicAlert bracelet
He is unconscious
He is breathing
He is diabetic per the bracelet (Correct answer)

Correct answer: He is diabetic per the bracelet

The diabetic condition provides EMS with critical medical history that can directly affect treatment decisions upon arrival.

Question 93: A caller reports a motor vehicle accident with injuries on a highway. Which agencies should typically be dispatched?

Police only
Police, fire, and EMS (Correct answer)
Fire department only
EMS and police only

Correct answer: Police, fire, and EMS

A highway accident with injuries typically requires police for traffic control, fire for extrication, and EMS for medical treatment.

Question 94: You are dispatching units for a residential burglary in progress when a second call comes in about a multi-vehicle accident with injuries. How should you prioritize?

Handle both simultaneously by using all available resources for each (Correct answer)
Cancel the burglary response and redirect all units to the accident
Finish the burglary dispatch completely before handling the accident
Place the accident caller on hold until the burglary is resolved

Correct answer: Handle both simultaneously by using all available resources for each

911 centers are designed to handle multiple incidents simultaneously; both calls must be processed with appropriate resources allocated to each.

Question 95: A supervisor's memo reads: 'Dispatchers should avoid using jargon that callers may not understand.' Which dispatcher response best follows this guidance?

'Units are en route; maintain radio silence until arrival.'
'I'm issuing a CAD entry for a Code 4 at your 10-20.'
'A 10-78 has been dispatched; stand by for further comms.'
'I'm sending officers to your location right now.' (Correct answer)

Correct answer: 'I'm sending officers to your location right now.'

Plain language ('sending officers to your location right now') is immediately clear to a civilian caller without requiring knowledge of codes.

Question 96: A caller is verbally abusive and uncooperative but is reporting what sounds like a physical altercation in the apartment next to theirs. What is the operator's most critical duty?

To maintain professional control and persistently attempt to gather the location and other critical details. (Correct answer)
To place the caller on hold until they calm down and are ready to speak civilly.
To warn the caller that their language is inappropriate and disconnect if it continues.
To match the caller's angry tone to assert authority and get them to cooperate.

Correct answer: To maintain professional control and persistently attempt to gather the location and other critical details.

The primary duty of a 911 operator is public safety. Regardless of the caller's demeanor, the operator must remain professional and use techniques like repetitive persistence to gather the essential information needed to dispatch help and ensure responder safety. Disconnecting or escalating the situation fails this primary duty.

Question 97: A caller describes a suspect fleeing in 'a blue four-door sedan going east on Highway 12 about 2 minutes ago.' What limitation does this information have?

The vehicle description is too vague to be useful
Highway information is not actionable for patrol officers
The caller should have provided a license plate
The time delay means the suspect's location has likely changed (Correct answer)

Correct answer: The time delay means the suspect's location has likely changed

A 2-minute-old location for a moving vehicle means the suspect could be significantly farther away, making the stated location outdated.

Question 98: A caller reports seeing someone breaking into a car: 'It's a red car — no wait, maybe maroon — in the mall parking lot on the east side, near the food court entrance.' What do you log for vehicle color?

Maroon
Red
Red/maroon — caller self-corrected, unconfirmed (Correct answer)
Unknown — caller was inconsistent

Correct answer: Red/maroon — caller self-corrected, unconfirmed

Noting the self-correction and logging both possibilities gives officers the most accurate picture of what the caller observed.

Question 99: A caller reports a minor fender-bender with no injuries while another line has a caller reporting chest pains. Which call takes priority?

The fender-bender because it was reported first
The fender-bender if it is blocking traffic
Both calls are equal priority
The chest pain call because it is a life-threatening emergency (Correct answer)

Correct answer: The chest pain call because it is a life-threatening emergency

Life-threatening medical emergencies always take priority over property damage incidents with no injuries.

Question 100: Which practice helps a dispatcher maintain accuracy when logging incident updates during a long, evolving event?

Timestamping each update as it occurs throughout the event (Correct answer)
Delegating all logging to a trainee to stay focused on radio
Summarizing all updates in a single entry at the end of the event
Typing updates from memory after the event concludes

Correct answer: Timestamping each update as it occurs throughout the event

Real-time timestamped entries create an accurate chronological record critical for after-action reviews and legal documentation.
