911 Dispatcher / Public Safety Telecommunicator Pre-Employment Test
Pre-employment and academy prep for 911 dispatchers — call taking, triage, radio, maps, memory and the data-accuracy drills hiring tests are built on.
About the exam
Every 911 center hires through its own selection process, but most use a short list of tests: CritiCall (a computer-based battery used by many U.S. and Canadian centers), the California POST Entry-Level Dispatcher Selection Test Battery, or a written test from a vendor or civil-service office. They measure the same core abilities — listening and remembering details, prioritizing, entering data quickly and accurately, reading maps, spelling and reasoning under time pressure.
After you're hired, academy and certification training (for example APCO Public Safety Telecommunicator courses, state certification and emergency medical dispatch certification) covers call processing, radio procedures, legal issues, stress and 911 technology. APCO's American National Standard 3.103.3-2025 sets the minimum training topics many agencies follow.
Our practice combines both: aptitude-style drills (data comparison, cross-referencing, map routing, memory passages, prioritization) and job-knowledge questions on call interrogation, radio, triage, confidentiality and NG911 — every answer explained. Check your agency's posting for the exact test it uses.

The exam blueprint
QuizMe composite blueprint (2026) built from the skills measured by common dispatcher selection tests (CritiCall, POST Dispatcher Selection Test Battery) and the job knowledge in APCO ANS 3.103.3-2025 Minimum Training Standards for Public Safety Telecommunicators. There is no single national dispatcher exam — your agency picks the test. — Call processing, prioritization, radio procedures, data entry and cross-referencing, map reading, memory and multitasking, legal and confidentiality, stress and professionalism, protocol concepts and 911/CAD technology.

Hints that teach
Reveal the rule, the priority logic or the shortcut when you're stuck. Every answer explains why the others fall short.
Adaptive practice
Questions steer toward your weakest skills — data entry, maps, memory or call handling — and get harder as you improve.
Timed practice tests
100 questions in 2 hours with a pacing indicator and full review.
Flashcards, walkthroughs and guides
Flashcards for the phonetic alphabet, priorities and terms, worked call walkthroughs and interactive guides.
Progress in every skill
Each area moves from Not started to Exam ready, so you know exactly what to work on next.
Test at home or at a center
Apply through the agency's job posting — it names the test, the typing requirement and the testing date. Many agencies test in person; some use remote CritiCall sessions.
Agency or testing center
- Bring the ID listed in your invitation; arrive early — many tests start on time with no late entry.
- POST battery subtests are timed separately; wrong answers can cost a fraction of a point, so guess only when you can eliminate choices.
- CritiCall uses a headset for audio modules — listen once, then type.
- Ask the agency whether a typing certificate (net words per minute) is accepted or tested on site.
After you pass
- Expect an oral board, background investigation and often a sit-along in the communications center.
- Hired dispatchers complete academy training and probation, often with state certification and EMD.
- Many centers require CPR and emergency medical dispatch certification within the first months.
- Retake rules vary — the POST battery requires a 30-day wait between attempts.
Exam-day game plan
How to walk in ready — and how to pace 100 questions in 2 hours.
Pacing checkpoints
Our timed test mixes all ten skill areas — 100 questions in 2 hours. Real dispatcher tests vary: the POST battery is 11 separately timed subtests, and CritiCall modules are chosen by each agency. Use domain practice to drill the modules your agency lists.
The week before
- Drill the phonetic alphabet until it's automatic.
- Practice data-comparison and cross-referencing sets on a timer.
- Run a typing test daily if your agency tests typing.
- Confirm the test location, start time and ID requirements.
During the test
- Location first, always — the first priority in any call question is where the emergency is.
- For memory passages, read for who, what, where, when and weapons/injuries.
- Compare data character by character — transposed digits are the classic trap.
- Pick the action that protects life and safety first, then property, then everything else.
- Watch each section's clock; move on rather than stalling.
Keep your head
- Calm and steady beats fast and sloppy on accuracy tests.
- One hard module doesn't decide your result — reset for the next one.
- Change an answer only for a clear reason.
After you're hired
- Most centers require continuing education each year; state certifications typically renew every 2 years.
- Emergency medical dispatch (EMD) certification usually requires CPR plus periodic recertification and CE.
- APCO ANS 3.103.3-2025 describes minimum initial and ongoing training topics many agencies adopt.
- Requirements vary by state and agency — check with your center's training coordinator.
