What sentence clarity measures
Whether you can write an incident note another responder can act on without re-reading it.
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.
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 sentence clarity
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.
The most widely used pre-employment assessment for 911 dispatchers and public-safety telecommunicators in the United States. It is modular: an agency picks which components to run, so no two agencies test exactly the same set.
POST Entry-Level Dispatcher Selection Test Battery
California Commission on Peace Officer Standards and Training
Used by California agencies. It is delivered on paper, with a pencil — not on a computer — and scores are reported as a T-score. Agencies set their own minimum.
How to get better at sentence clarity
Specific to this module, and specific enough to change what you do on your next run.
Ask who did what to whom
The clearest version of a sentence is almost always the one where the actor, the action and the target are unambiguous. If you have to hold two possible readings in your head, that option is not the answer.
Watch for pronouns with no clear owner
"He told him he would respond" is the classic failure. When a sentence has two people and a pronoun that could point at either, the version that names the person is the clearer one, even if it is longer.
Look for the misplaced modifier
A descriptive phrase attaches to whatever is nearest to it. Options that place it next to the wrong noun produce sentences that are grammatically fine and factually absurd — spotting that quickly is most of this module.
Shorter usually wins, but not always
Brevity is a good default tiebreaker, and it is also the trap. A short option that has dropped a necessary qualifier is less clear, not more. Check that the shorter version still says everything the longer one did.
Read it as the responding unit would
The practical test is whether someone driving to a scene could act on the sentence without re-reading it. That framing resolves most items faster than grammatical analysis does.

Common questions
Is this a grammar test?
Not really. Options are usually all grammatically acceptable — what differs is whether a reader can extract the intended meaning on a single pass. It is closer to a clarity judgment than a rules test.
Why does sentence clarity matter for the job?
Because incident notes are read by someone en route to a scene, often on a screen, often quickly. A sentence that needs re-reading is a delay, and occasionally a wrong assumption.
Do I need to know grammar terminology?
No. You never have to name a construction, only pick the clearer sentence.
Are the answers subjective?
The items are written so that one option is clearly better on a specific, statable ground — an ambiguous reference, a misplaced modifier, a dropped qualifier — and each explanation says which. Items where reasonable people would genuinely split are not useful practice, so we do not include them.
