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.
What you'll practice
21 timed modules, each with a breakdown of where your points went.

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, and every paid drill has a short free sample. The full timed drills, including the versions with emergency interruptions, the audio drills 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. Our interruption drills put a message in front of you mid-task so you can practice the switch; they ask read-back questions (which unit, which address, which plate) rather than CritiCall's agency-selection items.
How fast do I need to type?
It varies by agency. Postings we checked in 2026 asked for 35 to 40 net words per minute, but the only figure that binds you is the one in your posting. 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, data entry and audio 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, and so do the call-taking and audio memory drills with headphones. The multitasking drill works on a phone but is much easier to practice at a computer.
What is the difference between Standard and Complete?
Standard ($29) unlocks the core timed drills, the interruption drills and the mock exam. Complete ($49) adds the audio call-taking, audio data entry and audio memory drills, the checking-and-listening multitasking drill, and the evaluating facts and unit assignment reasoning drills. If you buy Standard first, you can upgrade later for the difference.
What happens after I pay?
You get instant access to every drill in your plan 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.
