Review the response, then practice another number.
Take one practice call.
A caller gives a name and an address and reports a problem. Type in capitals while the call plays, then choose who to send. Your answers stay in your browser.
This fictional call uses a natural-sounding AI voice. It is not a real 911 recording or an official test item.

Honest practice.

Dispatcher Prep is independent practice for people preparing for 911 dispatcher tests in the United States. It is not an official test, is not affiliated with CritiCall or any hiring agency, and cannot predict your result.
Agencies choose their own modules and passing scores, and we do not guarantee a pass or a job. Practice calls are fictional, use AI voices and are not emergency-response training.
One payment, no subscription. Try an exercise first, and buy only if it helps. No invented testimonials and no automatic renewal.
See pricing →Frequently asked questions
Is this an official CritiCall practice test?
No. Dispatcher Prep is independent practice covering skills that dispatcher tests measure. The exercises, scoring and circuit are our own, and they contain no real test questions. Check your hiring agency’s instructions for the exact assessment and requirements.
Which dispatcher tests does this help with?
We built it around abilities described in public guidance for 911 pre-employment testing, including CritiCall. Other tests, such as ECOMM or a state POST dispatcher test, may overlap in part. Agencies choose their own modules, so compare your notice with our skill list.
Will this guarantee I pass?
No, and nobody can honestly promise that. Practice scores describe your sessions here. Hiring agencies set their own tests and passing scores.
Are the voices real people?
Practice calls use natural-sounding AI voices generated with Kokoro, an open-weight speech model. Digit drills use recordings of human speakers. No exercise uses a real 911 call, and all names and addresses are fictional.
Can I use a phone?
Written reasoning and memory exercises can be explored on a small screen. Use a computer with a physical keyboard for live data entry, note-taking, typing and the full circuit.
Do I need an account?
Not to try it. The sample exercise and guest practice work without an account. A free account saves your history across computers.
How much does it cost?
Trying an exercise is free. Full access is a one-time payment of $29 for 12 months, with no subscription and no auto-renewal. See the pricing page for the refund policy.
