Most people who get invited to a dispatcher exam are never told what it is called. Pick what your invitation says below and we will tell you, in plain English, the most likely test and what is in it. Then take a free timed practice test in that format and see where you stand.
Every dispatcher screening exam in use today is built to answer one question: can you listen, type, read and decide at the same time, while someone is shouting at you and the clock does not stop. That is the job, so that is the test.
A caller gives you an address once, at speed, half of it wrong, while you are already entering the previous line. You do not get to ask them to slow down twice. The exam recreates this with audio playing while you type into a form.
You have to commit to a priority before the picture is complete. Four calls are ringing, one of them is quiet and dying, one of them is loud and fine. Ranking them correctly with incomplete information is a scored skill, not a personality trait.
An address off by one digit is a unit sent to the wrong block. The exam scores transcription accuracy under exactly the conditions that break it: divided attention, no repeats, a running timer.
This is why people who are excellent at their current job still fail. Nothing else you do rehearses these skills stacked on top of each other. Most candidates only discover that in the exam room.
CritiCall is modular: your agency selects which modules you sit, so no two candidates get an identical exam.2 These are the modules PrepTerminal covers. Ask your agency which ones are in your version, because it is a normal question and they will usually answer it.
| Module | What it measures | Why candidates lose points |
|---|---|---|
| Cross Referencing Accuracy | Matching a caller detail against a table of records, addresses, ranges or codes. | They match on the field that looks familiar instead of checking every field. Two records differ by one transposed digit and only one of them is right. |
| Map Reading Spatial | Reading a street grid, giving directions, choosing a legal route to an incident. | They pick the shortest line on the map and ignore the one-way arrows and the closure. A route that cannot legally be driven is a wrong answer. |
| Memory Recall Removed from screen | Holding an address, unit ID, complaint and callback number after the record disappears. | They rehearse the whole card instead of the two fields most likely to be asked. Unit IDs and apartment numbers are where the transposition traps live. |
| Prioritization Judgment | Ranking simultaneous incidents by acuity when you cannot send everyone. | They rank by how loud the caller is. The dangerous call is usually the calm one: chest pressure, agonal breathing, a child who has gone quiet. |
| Sentence Clarity Language | Choosing which of two dispatch sentences is clearer and less ambiguous. | They pick the longer, more formal sentence. Broadcast language is judged on whether a unit can act on it, not on how official it sounds. |
| Data Entry Typed, timed | Transcribing spoken addresses, names and numbers into fields, accurately, at speed. | They chase speed. Scoring weighs accuracy heavily, and one wrong digit invalidates the whole record. |
| Numerical Ability Mental math | Distance, time, ETA and unit arithmetic done in your head while the call continues. | They divide the wrong way round. Miles over speed, not speed over miles, and the trap answer is always the inverted one. |
| Probability Reasoning | Reading likelihood from incident and call-volume data. | They answer the complement of the question. If the question asks how likely it is to be genuine, the false-alarm rate is sitting right there as the trap. |
| Reading Comprehension Policy | Applying an SOP or policy paragraph to a live situation exactly as written. | They apply what the policy should say. The scored answer is what it does say, including which clock the deadline runs from. |
Module names as published by PrepTerminal course coverage, retrieved 2026-08-11.2 CritiCall publishes no candidate-facing spec, and the number of modules, the time limits and the cut score are all set by the hiring agency, not by the test publisher. Where sources disagree we say so instead of picking the tidiest figure.
It is almost never ability. It is two specific preparation habits, and both are trainable in an evening.
People drill typing on one site, map questions on another, and memory games on a third. The exam never gives you one skill at a time. It plays audio while you type, then asks you to recall what you typed, then asks you to rank four incidents against each other. Practising the parts in isolation builds a skill you never get to use. Practice has to be stacked and timed or it is measuring something the exam does not.
Typing gets all the attention because it is the one number candidates can see improving. But raw speed is only half of what is scored: accuracy under split attention is the other half, and it is the half that collapses first. A candidate who types 55 WPM cleanly while listening beats one who types 75 WPM and drops a digit in the house number. Speed you can only hold in silence is not the speed that gets scored.
There is a third thing almost nobody preps for: you usually cannot go back. Most modules move forward only, and an unanswered item scores zero. Guessing beats skipping every time, and knowing that in advance is worth points on its own.
Not a bigger question bank. A route through it, ordered by the module costing you the most, with the stacked and timed practice the format actually demands.
800+ practice questions across 52 scored quizzes, every module graded from practice through easy, moderate and hard, each with a written explanation that names the trap rather than just marking you wrong.5
60+ audio call simulations: real-pace callers, unclear addresses, background noise, and a form to fill while they are still talking. This is the part text practice cannot train.
Typing drills in the exam's own shape: transcription while listening, not a blank speed test. Speed and accuracy reported separately, because the exam scores them separately.
Cross Referencing, Map Reading, Memory Recall, Prioritization, Sentence Clarity, Data Entry, Numerical Ability, Probability and Reading Comprehension. All of them, so whichever set your agency selected is covered.
Score and feedback the moment you finish each drill, broken down by module, so you stop guessing which one is holding your result down and start fixing it.
Prioritization and judgment scenarios drilled against the clock, with the reasoning rule behind each one: rank by acuity, not by volume. The quiet call is usually the emergency.
Counted, not estimated: the figures above are the course's own published quiz sizes, summed across every module in the CritiCall QuickPass™ syllabus on 2026-08-16. We would rather give you the number we can show our working for than the larger one.5
We could have put a fake typing question in the free test. It would have looked good and told you nothing. Here is the honest version instead.
It is not a blank speed test. On a dispatcher exam, typing is normally transcription: audio plays, or text is displayed, and you enter it into fields while it is still coming at you. Some versions play a caller and ask you to enter the incident details as they are spoken. Both speed and accuracy are recorded, and they are reported as separate figures because they are separate skills.
Practising on a generic typing-speed website trains the wrong thing: those sites give you a clean passage in silence and let you settle into a rhythm. Nobody on a 911 line will let you settle into a rhythm.
There is no single national minimum, and any site quoting you one number is guessing.3 The hiring agency sets its own required words per minute and its own accuracy threshold, and the two are usually stated together, because a fast typist with a 4% error rate is not useful in a dispatch center.
Ask the agency directly: "What is the required typing speed, is there a separate accuracy requirement, and is it net or gross WPM?" Net WPM subtracts your errors. Gross does not. Agencies that quote a number without saying which one they mean are usually quoting net.
Everything except typing: cross referencing, map reading, memory recall, prioritization, sentence clarity, data-entry accuracy as a multiple-choice check, numerical ability, probability and reading comprehension. That is nine of the modules and it is enough to show you which kind of thinking is costing you points. It is not enough to tell you whether you will clear a typing threshold. The typing drills live in the course, where audio and a keyboard can be put in front of you properly.
Identify the exam, find the module costing you the most, then drill that one first rather than starting at module one like everybody else.
Ten seconds with the identifier at the top of this page, then ten minutes with the free diagnostic. You finish with a raw score, a module-by-module breakdown, and the name of the module holding your result down.
Weakest module first, not module one. Cross-referencing discipline, route legality on the map, the acuity ranking rule for prioritization, and the transcription drills that hold accuracy together while audio is running. Roughly two to three hours.
Callers at real speed with a form to complete while they are talking, then a full timed run so you can see whether your accuracy held under split attention and not just whether your score went up.
Modules named, outcomes named. Every review links to the verified original.
This course was really helpful with every topic that was on the actual test. I felt very prepared after seeing how similar the real exam was to the content given. I passed the exam on my first try.
I did the month long critical prep course! It for sure prepared me very fast and accurately. When doing my assessment for dispatch I felt as if I had done everything and did not panic!
I loved the course and the practice exams. It really targeted all the items I needed to prepare for my Emergency Communications Officer Exam. I actually passed my exam!
Three real reviews, quoted verbatim from our public Trustpilot profile and each linked to its original. Every one is from a dispatcher or CritiCall candidate. Notice the third: he calls his exam the Emergency Communications Officer Exam, not CritiCall — which is the reason this page exists.
A real street map to route a unit across. A caller-record table to cross reference. A dispatch card to hold in your head. Four calls ringing at once and one unit to send. Instant score, module breakdown and a written explanation for every question.

The most common email I get from dispatcher candidates is not about a question. It is "I have a test next week and I do not know what it is called." That is a preparation problem nobody was solving, so this page answers it first and sells second. If the identifier above tells you your exam is not CritiCall, do not buy the CritiCall course. Email me instead and I will tell you what I actually know and what I do not. I answer questions about the modules, the typing component and the agency process myself at [email protected].

There is no single national exam. "911 dispatcher test" is the job, not the test name, which is exactly why so many candidates arrive without knowing what to prepare for. In practice the screening is usually one of three things: a computerised multitasking exam (CritiCall is the one most commonly used by 911 centers), a video-scenario exam in the Ergometrics family, or a state POST or civil service entry exam. Whichever it is, they all test the same underlying job: listening, typing, reading and deciding at the same time. Use the identifier at the top of this page as a starting point, then confirm with the hiring agency.1
Often, but not always, and we cannot tell you which it is for your agency without you asking them. CritiCall is the most widely used pre-employment test for 911 communications roles, so it is the most likely single answer, but agencies also use Ergometrics-style video exams, state POST exams and in-house written tests, and some use two of them in sequence.1 If your invitation does not name the exam, ask. It is a normal question and hiring staff answer it every week.
There is no universal minimum and we will not invent one for you. Each agency sets its own required words per minute and its own accuracy threshold, and the two are usually stated together.3 Ask the hiring agency three things: the required speed, whether there is a separate accuracy requirement, and whether the number is net or gross WPM. Net subtracts your errors, gross does not, and the difference between the two can be ten or more words per minute for the same typist.
Usually yes, but the waiting period is set by the agency, not by the test publisher, and it varies from a few months to a full hiring cycle.4 Some agencies also cap the number of attempts within a period. Ask before you sit it, because the answer changes how much preparation is worth doing now versus later.
It depends entirely on which modules your agency selected, because CritiCall is modular and the agency chooses the set.2 Candidates commonly report sittings in the region of one to three hours including the typing component. Treat any site quoting you one exact duration with suspicion: they cannot know which modules you were assigned.
The hiring agency sets the cut score, not the test publisher, and agencies do not always publish it.4 Some use a single overall threshold, some require a minimum in each module, and some rank everyone who clears the bar and hire from the top down. The free diagnostic on this page measures you against 80 percent as a working target. That is our editorial benchmark for "comfortably clear", not a published cut score, and we label it that way on the results screen.
No. PrepTerminal is independent and is not affiliated with, endorsed by or sponsored by CritiCall, Biddle Consulting Group, Ergometrics, National Testing Network or any public safety agency. Our practice material is built to match the published module structure. It is not licensed content and it is not the real exam.
Yes, and that is who the QuickPass™ path is built for. Take the free diagnostic first: ten minutes tells you which module is costing you the most. Then spend the first evening on that module and the second on audio call simulations, which is the format nothing else in your life rehearses. The core path is about three focused hours. What it will not do in two days is move a typing speed a long way, so if the typing threshold is your problem, be realistic about that and tell the agency you would like to reschedule if that is an option.
No, and we would rather say so than pretend. A twelve-question multiple-choice diagnostic cannot measure typing speed or transcription accuracy in any meaningful way, so we have not faked one. The free test covers the nine reasoning and accuracy modules. Typing drills, in transcription format with audio, are in the course.
