911 dispatcher practice test
Practice for the 911 dispatcher test the way it actually runs
Most practice tests drill one skill at a time. The real assessment doesn't. DispatchDrills runs timed drills for the skills CritiCall, ECOMM and POST dispatcher tests measure — and then interrupts you mid-task with an emergency message you have seconds to handle. That's the part candidates say catches them out.

Why divided attention is the whole game
You can be a fast, accurate typist and still struggle, because the assessment doesn't let you finish a thought. An emergency message appears while you're mid-record, and the clock on it is short. Practicing data entry on its own tells you nothing about how your accuracy holds up once something else is demanding an answer.
Our interrupt drills log every keystroke and every timeout, so after a run you can see exactly where you dropped accuracy — and whether it was the interruption or the recovery afterwards that cost you.
CritiCall says its test is used by over 1,500 agencies, and by half of all state police. Whichever agency you are applying to, the divided-attention problem is the same one.

Which assessment are you sitting?
Agencies use different vendors, and each picks its own combination of modules. The underlying skills overlap heavily, which is why we train the skills rather than imitating one vendor's format.
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.
Emergency Communications (ECOMM) Exam
Ergometrics & Applied Personnel Research, Inc.
An Ergometrics-developed exam delivered through National Testing Network, in a Comprehensive (video) version and an Express version. Candidates book it themselves, online with a live proctor or at a test center, and NTN sends the scores to each participating agency they choose. It is a different product from the National Dispatcher Selection Test (NDST), which is published by Stanard & Associates — the two are frequently confused.
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.

Common questions
What score do I need to pass?
There isn't a single national pass mark. These assessments are modular — each hiring agency chooses which components to run and sets its own minimum score for each one. That's why two candidates can perform identically and get different results at different departments. Check the job posting and the agency's own candidate information for the requirements that apply to you.
Is there a free 911 dispatcher practice test?
Yes. The typing test, the data entry drill and twenty practice questions with answers are free, with no account or email. The full set of timed drills, including the versions with emergency interruptions, and the mock exam are a one-time payment.
What are the emergency interruptions?
In some assessments an emergency message appears while you are already working on another task, and you have a short window to respond — CritiCall's candidate preparation guide gives 15 seconds per message. It measures divided attention, and it is the part candidates most often report being caught out by, because most practice material tests each skill in isolation instead.
How fast do I need to type?
It varies by agency. Minimums commonly fall somewhere in the 30 to 45 words-per-minute range, and it is usually a hard gate rather than a scored component — you either clear it or you don't continue. Accuracy is counted alongside raw speed. Our typing drill is free and reports net WPM and per-field accuracy.
Do I need a physical keyboard?
For the typing and data entry drills, yes — they measure keyboard speed and accuracy, so a phone touchscreen will give you a misleading score. The multiple-choice modules (spelling, reading, memory, prioritization, decision making) work fine on a phone.
What happens after I pay?
You get instant access to every drill with unlimited attempts. It is a one-time payment — there is no subscription and no recurring charge, and access does not expire.
Can I get a refund?
Yes. If it isn't right for you, get in touch within 14 days of purchase and we will issue a full refund, no questions asked.
