Everything that costs nothing
Free 911 dispatcher practice tests and tools
Everything on this page works without an account, without a card, and without handing over an email to see your result. We ask for an email in exactly one place — beside a result you have already been given, for a discount code you can ignore.
If you only do one thing: get a real measurement rather than an impression. Most people are surprised by the gap between how fast they type prose and how accurately they type addresses and plate numbers.
Free tools
Nothing here is a teaser for a paid version. Each one gives you the whole answer.
Typing test
FreeA timed run that reports gross WPM, net WPM and accuracy separately. The result appears the moment the run ends — it is never held behind an email.
20 practice questions
FreeOriginal questions in the formats dispatcher tests use — comparison, memory, rules-based priorities, reading, math and maps — with every answer explained.
Typing goal calculator
FreePut in your speed, accuracy and target. It works out your net rate and tells you which lever — accuracy or raw speed — is the one actually holding you back.
Dispatcher readiness check
FreeFifteen honest questions about shift work, emotional load and background readiness. It will tell you if the answer looks discouraging, because that is the useful version.
Free practice modules
Full modules, not samples. They generate fresh records every run, so you cannot memorize your way through them and you will not run out of items.
Data Entry
Type caller and incident details into a fixed-field form, accurately, against the clock.
Keyboard accuracy and speed under time pressure, and your ability to hold a record in working memory while transcribing it.
Typing Speed & Accuracy
Timed typing runs with live words-per-minute and accuracy scoring.
Net typing rate — speed with uncorrected errors deducted. Depending on the agency and the battery, this can be a scored component, a minimum you either clear or do not, or both at once: CritiCall's keyboarding module reports a WPM figure that is scored, while many agencies additionally set a separate floor you must reach to continue. Published minimums we have seen commonly sit somewhere in the region of 30 to 45 WPM, but that is a range of what agencies advertise rather than a standard, and the only figure that governs you is the one in your own job posting.
The keyboard-marked modules measure physical typing speed and accuracy. A phone touchscreen will give you a number that does not reflect how you will perform on a test-center keyboard, so use a laptop or desktop for those.
A sensible order to do this in
Diagnosis before practice. Almost everyone who skips the measuring step spends their best hours on the skill they were already good at.
- Run the readiness check first. It costs three minutes and it is the only step that can tell you not to bother with the other four.
- Take the typing test and write down all three numbers — gross, net and accuracy. Not just the one you liked.
- Run the free data entry drill. Compare it to your typing result. The gap between prose speed and alphanumeric accuracy is the single most informative number you will collect.
- Put those numbers into the goal calculator against the minimum printed on the job posting you are actually applying to.
- Then build a routine. Our guide to a realistic weekly practice schedule covers the open-ended case, and the two-week plan covers the case where you already have a date.

What is not free, and why we are telling you here
The rest of the modules are paid. We would rather you saw the whole list on the free page than discovered it after clicking. $29 once, every module, unlimited attempts, no subscription.
The same is true of the full timed mock exam — several modules back to back in one sitting, with the emergency interruptions running, and one report at the end. Practicing a module in isolation tells you your ceiling; a full sitting tells you whether your accuracy survives an hour of it, which is the number that matters.
Cross-Referencing
Look a value up in a reference table and report the matching record.
Character Comparison
Decide whether two strings of letters and numbers are identical.
Math & Probability
Arithmetic, elapsed time, distance and simple probability questions.
Data Entry with Emergency Interruptions
Data entry, interrupted by emergency messages you must answer within 15 seconds.
Cross-Referencing with Emergency Interruptions
