- CritiCall has more than 20 selectable subtests; your agency's battery - not a fixed national exam - determines what you actually see.
- Typical agency batteries run 1 to 3 hours, so stamina and pacing matter as much as raw skill.
- Emergency-message items give you just 15 seconds to route a call to Police, Fire, EMS, or Utility.
- Tab and Shift+Tab move between fields, and many fields accept uppercase-only input - small mechanics that cost points if unpracticed.
What the CritiCall Test Actually Measures
CritiCall is not a knowledge exam you can cram for with a textbook. It's a pre-employment work-sample assessment developed by Biddle Consulting Group and delivered through the TestGenius: CritiCall platform, built specifically to simulate the demands of a 911 dispatch or call-taking environment. You don't need prior dispatcher training or specialized public-safety knowledge to take it - the entire point is to observe how you handle competing information streams under time pressure, not what you already know about radio codes or CAD systems.
If you're new to the assessment altogether, start with our overview of what CritiCall is and how it fits into the hiring process, or read what CritiCall certification actually means for applicants. Because "CritiCall" gets used loosely, it's also worth reviewing what the CritiCall name refers to in this context before you start prepping.
Format, Timing, and Interface Mechanics
Every agency builds its own battery from the CritiCall subtest library, which is why two candidates applying to different communication centers can have noticeably different testing experiences. What stays consistent is the underlying software mechanics, and knowing them cold before test day removes an entire category of avoidable errors.
- Battery length: Agency batteries average 1 to 3 hours total, combining several subtests back to back.
- Practice items: The candidate guide confirms practice items are unscored - use them to learn the interface, not to worry about accuracy.
- Audio delivery: Some sections deliver audio through a headset, meaning you're typing or selecting answers while listening in real time.
- Field navigation: Tab and Shift+Tab move you between fields - mousing around instead wastes seconds you don't have.
- Input case: Many fields accept uppercase input only, which trips up candidates who aren't used to typing that way under pressure.
- Skipping penalties: Skipped questions may be penalized according to that section's specific instructions, so read each subtest's directions instead of assuming the rules are uniform.
These mechanics alone can determine whether a capable candidate passes or stumbles. For a deeper breakdown of exactly how scoring thresholds work, see our guide to the CritiCall passing score, and if you're still deciding whether the effort is worth it, our ROI analysis lays out the tradeoffs.
The Core Skill Areas You Must Master
CritiCall draws from a bank of more than 20 selectable tests, and the abilities they measure cluster into recognizable skill areas. You won't necessarily see all of them - your agency picks the combination relevant to its dispatch position - but preparing across this full list is the only way to be ready no matter which battery you draw.
Multitasking and Prioritization
You'll be asked to manage several simultaneous inputs - for example, tracking one task while responding to another - which mirrors the reality of monitoring radio traffic while entering data. Practice deliberately switching attention between two active tasks without losing accuracy on either.
- Don't fixate on finishing one thread before checking the other; alternate on a rhythm
Map Reading
Expect items that test your ability to interpret a map quickly - locating an address, identifying the nearest cross street, or determining direction of travel. Speed and spatial accuracy both matter here.
- Practice scanning grid-style maps for landmarks and intersections quickly
Memory Recall
Some items present information briefly, then remove it before asking you to answer. This measures short-term retention under pressure rather than long-term study recall.
- Rehearse holding 4-6 discrete facts (names, numbers, addresses) for 10-20 seconds
Data Entry and Keyboarding
Because many CritiCall subtests require typing information you just heard or read, keyboarding accuracy and speed directly affect your score - not just your general typing test results.
- Practice typing while simultaneously listening to spoken information, not just from a printed page
Cross-Referencing and Perceptual Comparison
These items ask you to compare two similar sets of data - names, numbers, addresses - and spot subtle discrepancies. Errors here usually come from rushing rather than lacking the skill.
- Slow down fractionally on comparison tasks; speed gains are meaningless if accuracy collapses
Spelling, Sentence Clarity, and Reading Comprehension
Written-language items check whether you can spell accurately under time pressure, judge whether a sentence is clearly constructed, and pull correct meaning from a passage - all skills a call-taker uses when documenting incidents.
- Review commonly misspelled words related to addresses, names, and emergency terminology
Probability, Decision Making, and Following Rules
Certain sections present rule sets or probability-based scenarios and ask you to apply them consistently. These test whether you can follow a written protocol exactly, even when it's counterintuitive.
- Re-read the rule before every item rather than relying on memory of a similar earlier question

Emergency Call Classification Drills
One of the most distinctive - and most nerve-wracking - parts of CritiCall is the emergency-message classification item type. You're given a short scenario and must decide, in 15 seconds, whether it should route to Police, Fire, EMS, or Utility. There's no partial credit for hesitation; the clock doesn't care that you're weighing two plausible answers.
Key Takeaway
Train this item type explicitly. Read short scenario snippets, force yourself to commit to one of the four categories within 15 seconds, then check your answer. Speed of decision - not just accuracy - is what's being measured.
Because these scenarios often contain overlapping cues (a structure fire with someone trapped touches both Fire and EMS, for instance), the skill you're building isn't memorizing a rulebook - it's recognizing the dominant, most urgent classifier in a compressed scenario and acting on it immediately.
A Realistic Study Timeline
Generic study techniques like spaced repetition or timed drills only help if you're applying them to the right CritiCall content in the right order. Here's a sequencing approach that respects how the battery is actually built.
Interface and Mechanics
- Learn Tab/Shift+Tab navigation and uppercase-field conventions
- Run through practice items to remove interface surprise
- Read every section's instructions on skip penalties
Foundational Skill Building
- Drill typing-while-listening for data entry accuracy
- Practice map reading and cross-referencing exercises daily
- Work timed spelling and sentence-clarity sets
Multitasking and Memory Under Pressure
- Combine two tasks at once (listen + type, read + compare)
- Practice short-term recall drills with increasing item counts
- Add 15-second emergency-classification reps daily
Full-Length Simulation
- Run a mock battery lasting 1 to 3 hours to build stamina
- Review weak subtests identified during practice
- Rest the day before your scheduled test
Use our one-page cheat sheet during the final week as a quick-reference review rather than a first-time study tool - it's designed for reinforcement, not initial learning.
Common Mistakes That Sink First-Time Candidates
| Mistake | Why It Hurts | Fix |
|---|---|---|
| Skipping unclear items casually | Some sections penalize skips per their specific instructions | Read each subtest's rules before starting it |
| Practicing typing without audio | Real items often require keyboarding what you hear, not just read | Drill with spoken prompts, not only text |
| Treating all 4 categories as equally likely | Emergency-message items require fast, confident routing decisions | Practice committing within the 15-second window |
| Ignoring interface conventions | Uppercase-only fields and Tab navigation slow untrained candidates | Rehearse navigation until it's automatic |
| Under-practicing stamina | Batteries run 1-3 hours; fatigue erodes accuracy late in the test | Simulate a full-length session before test day |
Who Uses CritiCall and Why It Matters
Public-safety communication centers use CritiCall as a screening tool precisely because it doesn't assume prior dispatch experience - it's designed to reveal aptitude in a generic simulated dispatch environment. That makes it common for agencies hiring 911 dispatchers and call-takers who may be coming from unrelated career backgrounds. If you're researching openings, our CritiCall jobs overview explains how the assessment fits into typical hiring pipelines, and our requirements guide covers eligibility basics agencies commonly expect before you even sit for testing.
Because the battery is customized per agency, it's worth checking with your specific department about test length and subtest composition where possible - some are transparent about which of the 20-plus tests they use, and that information should directly shape your prep priorities. You can also review our exam dates and scheduling guide to understand how testing windows are typically organized, and the cost breakdown if you're budgeting for the process.
For continued practice once you've absorbed the fundamentals, our full practice test platform lets you rehearse the specific item types described above under realistic timing, and you can return to this CritiCall practice hub as your test date approaches to keep skills sharp.
Frequently Asked Questions
No. CritiCall is designed as a work-sample simulation of a generic dispatch environment and doesn't require prior dispatcher knowledge or training - it measures underlying aptitudes like multitasking, memory, and comprehension instead.
It depends on which subtests your agency selects from the more than 20 available, but agency batteries average 1 to 3 hours in total length.
It depends on the section. According to the candidate guide, skipped questions may be penalized according to that section's specific instructions, so always check the rules given before each subtest rather than assuming a uniform policy.
You have 15 seconds to classify each emergency-message scenario as Police, Fire, EMS, or Utility, which is why practicing fast, confident decisions on this item type matters as much as accuracy.
No. Each hiring agency chooses its own battery from the pool of more than 20 selectable tests, so the exact combination of subtests you face depends on the position and department you're applying to.
