What reading comprehension measures
Extracting a specific fact or rule from policy-style writing, quickly and without inference.
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 reading comprehension questions
Try these before you start the timed drill. Each one shows the answer and why when you open it.
Question 1
Riverbend County Communications General Order 4.02 governs routine radio traffic. Center policy requires that every unit acknowledge dispatch within thirty seconds of the initial call sign. If a unit does not acknowledge after two attempts, the dispatcher shall assign the call to the next available unit in the same district and note the failed attempt in the CAD narrative. Priority-one traffic is broadcast on Channel 1 in all cases other than an active tactical operation, during which Channel 1 is cleared and priority-one traffic moves to Channel 3. Dispatchers may use plain language at any time and must use plain language whenever a mutual-aid partner is on the channel. Ten-codes are not permitted on Channel 3. A dispatcher shall not clear a unit from a call until the unit provides a disposition code, unless a supervisor authorizes an administrative clear. Radio checks are conducted at the start of each shift, no later than fifteen minutes after the shift begins.
According to the passage, when does priority-one traffic move to Channel 3?
- Whenever a mutual-aid partner is on the channel
- Whenever ten-codes are in use
- During an active tactical operation
- When a unit fails to acknowledge after two attempts
Show answer
C. During an active tactical operation — The order says priority-one traffic is on Channel 1 "in all cases other than an active tactical operation." A mutual-aid partner on the channel triggers plain language, not a channel change.
Question 2
Riverbend County Communications General Order 4.02 governs routine radio traffic. Center policy requires that every unit acknowledge dispatch within thirty seconds of the initial call sign. If a unit does not acknowledge after two attempts, the dispatcher shall assign the call to the next available unit in the same district and note the failed attempt in the CAD narrative. Priority-one traffic is broadcast on Channel 1 in all cases other than an active tactical operation, during which Channel 1 is cleared and priority-one traffic moves to Channel 3. Dispatchers may use plain language at any time and must use plain language whenever a mutual-aid partner is on the channel. Ten-codes are not permitted on Channel 3. A dispatcher shall not clear a unit from a call until the unit provides a disposition code, unless a supervisor authorizes an administrative clear. Radio checks are conducted at the start of each shift, no later than fifteen minutes after the shift begins.
Under this policy, a dispatcher may clear a unit without a disposition code:
- only when a supervisor authorizes an administrative clear
- whenever the unit has been on the call more than thirty minutes
- at any time, provided the CAD narrative is updated
- never, under any circumstance
Show answer
A. only when a supervisor authorizes an administrative clear — The passage says the dispatcher "shall not clear a unit ... unless a supervisor authorizes an administrative clear." The flat "never" option ignores that stated exception.
Question 3
Riverbend County Communications General Order 4.02 governs routine radio traffic. Center policy requires that every unit acknowledge dispatch within thirty seconds of the initial call sign. If a unit does not acknowledge after two attempts, the dispatcher shall assign the call to the next available unit in the same district and note the failed attempt in the CAD narrative. Priority-one traffic is broadcast on Channel 1 in all cases other than an active tactical operation, during which Channel 1 is cleared and priority-one traffic moves to Channel 3. Dispatchers may use plain language at any time and must use plain language whenever a mutual-aid partner is on the channel. Ten-codes are not permitted on Channel 3. A dispatcher shall not clear a unit from a call until the unit provides a disposition code, unless a supervisor authorizes an administrative clear. Radio checks are conducted at the start of each shift, no later than fifteen minutes after the shift begins.
By when must radio checks be completed?
- Within thirty seconds of the initial call sign
- Before the shift begins
- Within thirty minutes of shift start
- No later than fifteen minutes after the shift begins
Show answer
D. No later than fifteen minutes after the shift begins — The final sentence sets the fifteen-minute limit. The thirty-second figure is the unit acknowledgment window, not the radio-check deadline.
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 reading comprehension
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.
CritiCall
Biddle Consulting Group, Inc.
A computer-based pre-employment test for 911 dispatchers and call takers from Biddle Consulting Group, which says it is used by over 1,500 agencies. It is modular: Biddle says the software holds over 20 tests and each agency picks the ones that fit its jobs, so no two agencies necessarily test the same set. Biddle puts a typical sitting at one to three hours.
POST Entry-Level Dispatcher Selection Test Battery
California Commission on Peace Officer Standards and Training
California's standard written test for public safety dispatchers: eleven short tests of verbal, reasoning, memory and perceptual ability. Six are written and five play audio, answers are marked on paper, and scores are reported as T-scores.
How to get better at reading comprehension
Specific to this module, and specific enough to change what you do on your next run.
Answer from the passage, not from experience
If you have worked in public safety, this is the specific way you will lose points. The correct answer is what the passage states, even when the passage describes a policy you know is handled differently elsewhere.
Read the question before the passage
Knowing what you are looking for turns a full read into a targeted search. On procedural text, that is a large time saving with no accuracy cost.
Hunt the conditions
Policy-style writing hangs on words like unless, except, only if, and after. Those words are almost always where the question is aimed, and skimming past one is the usual cause of a confidently wrong answer.
Locate the exact sentence before you commit
For any answer you choose, you should be able to point at the sentence that supports it. If you cannot, you are inferring — and inference is where the distractor options are waiting.
Watch for negation in the question stem
"Which of the following is NOT required" reverses the whole item. Slowing down on the stem specifically, rather than on the passage, is worth more than it sounds.

Character Comparison
Decide whether two strings of letters and numbers are identical.
Sentence Clarity
Choose the clearer, better-constructed version of a sentence.
Memory & Recall
Study details for a short period, then answer from memory.
Data Entry
FreeType caller and incident details into a fixed-field form, accurately, against the clock.
Common questions
What kind of passages are used?
Short procedural and policy-style text of the kind you would encounter in an agency manual or a standard operating procedure — the register the assessment uses.
Do I need any prior dispatch knowledge?
No, and it can work against you. Every answer is contained in the passage, and answering from what you know rather than what the text says is the most common way experienced candidates lose points here.
How long do I get?
The drill is timed generously enough to read carefully but not to read everything three times. That is deliberate — the module is partly about reading efficiently.
Can I take this on a phone?
Yes. It is a reading module and works fine on a phone, though longer passages are more comfortable on a larger screen.
