What prioritization measures
Triage judgment — life safety over property, in-progress over cold, confirmed over reported.
These assessments are modular — an agency chooses which components to run and sets its own minimum for each one. We can tell you what the skill is and how to get better at it. We can't tell you what score your agency wants, and anyone who quotes you a universal one is guessing.
Sample prioritization questions
Try these before you start the timed drill. Each one shows the answer and why when you open it.
Question 1
One patrol unit has just cleared and four calls are holding. Which should it be sent to first?
- A third complaint tonight about loud music from the same address after midnight
- A shoplifter detained by store security in the manager's office, cooperative
- An elderly man lying motionless on a sidewalk, breathing status unknown
- A dog running loose on a residential street, darting between parked cars
Show answer
C. An elderly man lying motionless on a sidewalk, breathing status unknown — A person down with unknown breathing status is a possible life threat and nothing else on the board is. The shoplifter is contained and supervised, and the noise and animal calls are quality-of-life matters. Agencies differ in how they route this; follow your own agency's protocol.
Question 2
Four calls are pending. Which cannot wait?
- An alarm activation at a closed hardware store with no further information
- A parked car found with a shattered window and the stereo gone, owner not present
- Two roommates arguing verbally in separate rooms, no weapons, no injuries
- Smoke from a neighbor's kitchen window; nobody has seen the neighbor today
Show answer
D. Smoke from a neighbor's kitchen window; nobody has seen the neighbor today — Visible smoke from an occupied residence whose occupant is unaccounted for combines an active hazard with a person possibly inside. The other three are property loss or a dispute that has already de-escalated. Where you work will have its own ranking scheme in policy; that protocol is the one that counts.
Question 3
A supervisor asks which holding call should go out next. Your answer?
- A woman whose husband just took a bottle of his heart pills and now will not respond
- A fight outside a bar that broke up twenty minutes ago; everyone has left
- A drive-off from a gas station where the driver pumped $70 and left without paying
- A vehicle alarm that has been sounding for an hour in an apartment parking lot
Show answer
A. A woman whose husband just took a bottle of his heart pills and now will not respond — A witnessed overdose with an altered level of consciousness is an immediate threat to life. The fight is over and the remaining two are property matters. This is general triage reasoning, not a universal rule; local policy governs.
How our drill works
It's timed. You get a countdown clock and a fixed run length, because working accurately with a clock visible is a different skill from working accurately without one, and only one of them is being assessed.
Each run samples a fresh set of questions from our bank, so repeated attempts give you a different selection rather than the same items in the same order. Every question carries a written explanation — the reasoning is the part that transfers to the next question.
When the run ends you get a breakdown, not just a percentage. The point is to show you where the points went, so the next run can be different.
Which assessments include prioritization
Agencies use different vendors, and each picks its own combination of components. This module appears in the batteries below — but check the job posting, because an agency using one of them may not run every part of it.
How to get better at prioritization
Specific to this module, and specific enough to change what you do on your next run.
Life safety first, every time
Threat to a person outranks threat to property, and that ordering resolves a large share of items on its own. When two incidents both involve people, the one where harm is ongoing outranks the one where it is potential.
In-progress beats cold
An incident happening now, where a response can change the outcome, outranks a report of something that has already finished. This is the second most useful sorting rule after life safety.
Confirmed beats reported
Where two incidents are otherwise comparable, the one with verified information generally outranks the one that is unconfirmed. Be careful with this one, though — it does not override an unconfirmed report of immediate danger to a person.
Sort the whole set before answering
Items give you several simultaneous incidents. Comparing them pairwise as you read tends to produce a locally sensible order that is globally wrong. Read all of them, then rank.
Read the explanations, not just the score
Prioritization is the module where knowing why an answer ranked where it did transfers most to the next item. The reasoning generalizes; the specific scenario does not.
Guide: sort the whole set, not pairs
The most common process error on prioritization items is comparing incidents two at a time. You weigh A against B, then B against C, and end with a chain of local decisions that do not add up to one consistent order. It is also slow. Sort the whole set in one pass instead:
- Scan for life threat. Mark every incident with a person in immediate danger. Nothing else matters until that group is found.
- Order that group by immediacy. Happening now beats about to happen beats already over. The number of people at risk breaks near ties.
- Order the rest by whether it is in progress. Current, then recent, then cold reports.
- Break remaining ties on information quality. Confirmed before second-hand.
One exception does a lot of work: an unconfirmed report of danger to a person is not demoted below a confirmed property problem. The cost of being wrong is lopsided, so life safety sits above the confidence question.
A worked example (invented)
| Call | What you have |
|---|---|
| A | Smoke alarm sounding at a closed hardware store on Ospringe Lane. The monitoring company is on the line; nobody is on site. |
| B | A calm caller thinks the neighbor at 3312 Marmot Ridge is having a medical emergency. They have not seen inside. |
| C | A screaming caller reports a two-car collision: no injuries, both cars drivable, one lane blocked. |
| D | A streetlight knocked down sometime overnight, found this morning, lying clear of the road. |
B is the only possible threat to a person, so it goes first; being unconfirmed and calm does not demote it. A is live and could change, so it is second. C is minor but current, and a blocked lane is a hazard, so it is third. D is cold and going nowhere. The useful part is C: the loudest call ranks third and the calmest ranks first.
Traps
- Loudness is not severity. The caller's volume tells you how to talk to them, not where the call goes in the queue.
- Detail is not importance. A three-line incident with a person in danger outranks a paragraph about a parking dispute.
- Resolved is not urgent. A fire already out or a hazard already cleared stays in your head as alarming words. Read every incident to the end before ranking any.
- Do not add facts. "The fire might reignite" is a sensible instinct and a wrong test answer. Rank what you are told.
When you get one wrong, find which pass failed: a missed life threat on the scan, a misjudged immediacy, or the pull of a loud caller. On the job, your agency's call priority scheme governs; this is reasoning for the test.

Common questions
Is there a single correct priority order?
For the items in our bank, yes — they are written so one ordering is defensible on a stated principle, and the explanation names that principle. In real dispatch, agency protocol and local policy govern, and a working dispatcher will correctly argue with anything presented as universal.
Do I need to know a specific agency's protocol?
No, and you should not assume one. The reasoning in our explanations is general practice, not any one jurisdiction's protocol. Where your agency's policy differs, your agency's policy is what governs on the job.
What is this module actually measuring?
Triage judgment — whether you can sort competing demands by which one a response changes most, quickly, without a supervisor.
Can I take it on a phone?
Yes. It is a reading and ranking module with no typing requirement.
What if two incidents look genuinely equal?
Recheck immediacy, then how many people are exposed, then how well the information is confirmed. If they still tie, the item is probably testing how you place the others in the set. Pick one and move on.
Does a rude or uncooperative caller change the priority?
No. Demeanor changes how you handle the conversation, not where the incident ranks, in either direction.
