What evaluating facts measures
Careful deductive reading: quantifiers, time order and conditions, without filling gaps from outside knowledge.
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: fifteen conclusions in six minutes, three at a time from each set of facts, with a near-even mix of True, False and Can't tell answers that is deliberately not exactly even. You can move back and forward between items and leave any of them blank.
Each run samples fresh fact sets from our bank, and every conclusion carries a written explanation that cites the facts by number. The reasoning is the part that transfers to the next item.
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 evaluating facts
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.
The same skill also turns up outside the batteries above, in other vendors' tests and in tests agencies build themselves, usually under a different name.
How to get better at evaluating facts
Specific to this module, and specific enough to change what you do on your next run.
"Can't tell" is a real answer, not a cop-out
Most wrong answers on this task are conclusions marked True because they are likely, or usual in real life. Unless the facts given prove it, the answer is Can't tell. Before choosing True, point at the fact or facts that force the conclusion; if you cannot, it is not True.
Rules only run one way
"Every weapon call is Priority 1" does not mean every Priority 1 call involves a weapon. It does mean a call that is not Priority 1 involves no weapon. Reversing a rule is the single most common trap, and it is worth checking every conditional conclusion for it deliberately.
Watch the small words
All, some, only, exactly, at least, before, after. A list is complete only when the facts say so. "Two units responded" does not rule out a third unless it says only two. These words decide most items, and they are easy to read past when you are moving quickly.
Reported is not the same as happened
A fact that says a caller reported a fire proves that the caller said so. It does not prove there was a fire. Conclusions that quietly turn a report into an event should usually be Can't tell.
Use the skill breakdown after a run
Results group your misses by type — quantifiers, if and unless, times and order, numbers, and assumptions from outside knowledge. Most people are consistently weak on one or two. Read the explanations for those items, which cite the facts by number, and drill that pattern specifically.

Common questions
What does the evaluating facts drill practice?
Deductive reading. You get a short set of numbered facts about a dispatch situation and decide whether each conclusion is True (the facts prove it), False (the facts rule it out) or Can't tell (the facts do not settle it). A timed run is fifteen conclusions in six minutes, with a review at the end explaining each answer.
Which dispatcher tests use this format?
California POST's entry-level dispatcher battery includes an Evaluating Facts test in a True, False or Can't tell format, with a sample in its examinee guide. Other tests measure the same skill under different names — New York City's Police Communications Technician exam notice lists deductive reasoning, and NTN's note-taking section asks candidates to mark statements Correct, Incorrect or Unsure. Formats and timings vary, and every item in our drill is original.
Should I leave items blank if I am not sure?
It depends on how your test is scored. POST's examinee guide says a fraction of a point is deducted for wrong answers while blanks count neither way, so blind guessing gains nothing there. Our drill lets you leave items blank and shows a guess-adjusted score next to your raw one, so you can see what your guessing is actually worth. Follow the instructions for your own test on the day.
Can I do it on a phone?
Yes. It is a reading task with three large answer buttons, so it works well on a phone. On a computer you can also answer with the T, F and C keys.
Is evaluating facts in Standard or Complete?
Complete. It was added with the POST-style reasoning drills in September 2026 and is included in the $49 Complete plan; Standard owners can upgrade for $20. The free sample has six conclusions and an untimed practice set with feedback after each answer.
