911 Dispatcher Test & Hiring in Missouri
What actually differs by state is the certification you need, not the skills the test measures. Here is how it works in Missouri — who sets the rules, whether there is a state certification, and where to apply — plus how to practice the hiring test itself.
Who sets the rules in Missouri
In Missouri, standards for 911 telecommunicators are set by the Missouri 911 Service Board (Department of Public Safety).
Missouri sets telecommunicator training in statute. Section 650.340 RSMo, the 911 Training and Standards Act, requires anyone hired as a telecommunicator or telecommunicator first responder after 28 August 1999 to complete the minimum training within twelve months of being employed, and to keep training thereafter for as long as they hold the role. The Missouri 911 Service Board oversees it.
- •Initial training is 16 hours for a police, fire or EMS telecommunicator first responder, and 40 hours for a joint communication center telecommunicator first responder.
- •Training must be completed within twelve months of being employed.
- •Ongoing training of at least 24 hours every three years is required for as long as the person remains in the role.
Rules change and individual agencies can set requirements above the state minimum, so always confirm the current standard with the official source before you rely on it. Start with Missouri 911 Service Board — training.
The pre-employment test in Missouri
The certification above is what Missouri requires to hold the job. Getting hired first means clearing a pre-employment skills test — and which one you sit depends on the agency, not the state. Some centers use a CritiCall-style skills battery, others use a National Testing Network (ECOMM) assessment, and others run their own. There is no statewide rule that fixes a single vendor, so the posting for the specific role is the only reliable place to find out which test applies to you. Our guide to what is on the 911 dispatcher test compares the common ones and shows how to tell from a posting which you will sit.
The good news is that it barely matters for how you prepare. Under the different names, these tests measure the same core abilities: fast, accurate data entry, cross-referencing and character comparison, holding caller details in memory, prioritizing incidents, reading comprehension, and typing under a clock — often with something interrupting you mid-task. Those are the skills our drills train, whichever test your Missouri agency ends up using. Test-specific pages: CritiCall, ECOMM. Most agencies also set a typing minimum; the free typing test tells you where you stand.

911 dispatcher hiring in Missouri — common questions
Do you need a state certification to be a 911 dispatcher in Missouri?
Missouri sets telecommunicator training in statute. Section 650.340 RSMo, the 911 Training and Standards Act, requires anyone hired as a telecommunicator or telecommunicator first responder after 28 August 1999 to complete the minimum training within twelve months of being employed, and to keep training thereafter for as long as they hold the role. The Missouri 911 Service Board oversees it. You can confirm the current rules with Missouri 911 Service Board (Department of Public Safety).
What test do Missouri agencies use to hire dispatchers?
It varies by agency. There is no statewide rule that fixes a single testing vendor, so one Missouri center may use a CritiCall-style skills battery while another uses a National Testing Network (ECOMM) test or its own assessment. The job posting for the specific role is the only reliable source for which test you will sit — and whichever it is, the underlying skills (data entry, cross-referencing, memory, prioritization, typing) are the same ones you can practice here.
Where do I apply to be a 911 dispatcher in Missouri?
Start with Missouri 911 Service Board — training for the current requirements, then apply to the individual agency or center that is hiring. Dispatcher jobs are posted by the employing PSAP, county, or department rather than through a single statewide portal.
Can I practice the Missouri dispatcher test online?
You can practice the skills the test measures, which is what matters — no legitimate site has the actual questions. DispatchDrills runs timed drills for data entry, cross-referencing, memory, prioritization and typing, with emergency interruptions, so you go in used to working accurately against a clock.
