911 Dispatcher Test Practice Tests: What Our Customers Are Saying
What Is the Dispatcher Test?
The dispatcher test is a selection procedure used by public safety agencies to screen candidates for the position of a 911 operator. Its goal is to hire people who have both the knowledge and ability to help someone in an emergency situation.
The Dispatcher exam usually consists of more than 10 test sections that evaluate different areas of aptitude. These areas include typing, listening, reading, setting priorities, speech recognition, memory, map reading, spatial orientation, and more.
Is the Dispatcher Test Hard?
The Dispatcher test is considered a hard exam since it simulates the challenging tasks of actual 911 dispatchers and because of the strict time limits in some of its modules. Also, since most candidates take the exam without any prior dispatch experience, they're often overwhelmed by its unique sections, such as multitasking, call summarization, and more.
That being said, it's definitely possible to prepare for this test and succeed, even if you have zero experience. That's because you can learn and improve all the skills and abilities that are being evaluated on this test.

What 911 Dispatcher Test You'll Likely Take
Most candidates for the many public safety dispatcher jobs in North America (911 operator, 911 call-taker, police dispatcher, emergency dispatcher, and more) take one of the following tests (click to jump to its section on this page):
CritiCall Test
The CritiCall test is the most widely used exam for 911 dispatchers in the United States and Canada. This test replicates the daily tasks of a 911 dispatcher, helping to evaluate the key abilities needed for success during training and in the actual role.
The CritiCall consists of multiple test sections, named "modules." Each agency chooses its modules from a pool of 25 sections, based on its needs and type of work.
The most common modules across agencies are typing, decision-making, data entry, call summarization, cross-referencing, and map reading.
Here’s an example of a CritiCall map reading question that closely mirrors the types of questions you’ll encounter on the actual exam.
CritiCall Map Reading Module
A man fainted at a grocery store on Lord Cir. A dispatcher ambulance is currently parked on the narrow road next to the medical center, between 29th St and King Cove.
What is the most direct route of the ambulance to reach the Lord Cir entrance of the grocery store?
Answer:
The correct answer is (C).
CritiCall Test Prep
CritiCall's map reading questions come in two main forms:
- Best Route: You'll be tasked with identifying the shortest, most direct path between two points.
- Orientation: You'll need to follow specific directions from a starting point to determine your final location.
Our CritiCall Preparation Pack includes a comprehensive Map Reading guide and 13 practice tests, offering hundreds of questions and a wide range of map types to help you master these skills.
CritiCall Data-Entry Module
The CritiCall Data Entry test assesses your ability to accurately and efficiently input information, such as names, license plate numbers, VIN numbers, addresses, and phone numbers, into the correct fields.
There are two formats for the Data Entry test:
- A split-screen format where the data is displayed on one side, and you must enter it into the empty fields on the other side.
- An audio version where you listen to an emergency call and enter the information you hear into the designated fields.
Your performance will be evaluated based on how quickly and accurately you input the data into the correct fields. Additionally, you'll need to respond promptly to any emergency messages that appear at the bottom of the screen
If you fail to respond to a decision-making message within 15 seconds of it appearing, your score will be negatively impacted.
Here is an example question taken from the JobTestPrep preparation.
JobTestPrep’s CritiCall preparation pack includes thorough practice for the Data Entry part, which is one of the most important modules of the exam. This practice will help improve your data entry skills and multitasking abilities (multitasking between data entering and responding to emergency messages).

National Dispatcher Selection Test (NDST Exam)
The National Dispatcher Selection Test (NDST) is used to evaluate the candidate's abilities in handling emergency calls, prioritization, decision-making, and teamwork. The exam takes about 85 minutes to complete and consists of between 83 to 113 questions.
It includes five sections designed to measure different aspects of dispatchers' performance
- Reading Comprehension
- Listening
- Problem-solving
- Prioritizing
- Multitasking
What If I Don't Know What Test Is Used By My Agency?
If you don't know what test is used by the agency you're applying to, we encourage you to contact your potential employer. Ask them for a detailed description of the selection process, including the pre-employment tests and other test administration info.
By getting this information beforehand, you'll know exactly what test to prepare for, and increase your chances of passing it.
What Topics to Expect on the Most Common Dispatcher Tests?
Several test sections are mutual to all 911 dispatcher tests in the U.S. and Canada. Here's a partial list of them - the full list is located on each exam page on our site.
Typing
To work as a public safety dispatcher, you have to possess a typing speed of at least 35 words per minute (WPM). On some tests, applicants are given one or two typed sentences and asked to type them accurately within 45 seconds or 60 seconds respectively.
In addition to these timed typing tests, you may be also asked to type a portion of text from memory in a certain amount of time.
There is also an audio typing test you might encounter. It works in the same way, except that instead of typing on the computer keyboard, you listen to an audio recording and type everything you hear.
Data Entry
The Data Entry section of the test is used to assess the candidate's dexterity and speed in handling data. Usually, it takes 10-30 minutes and the entries might include the caller’s name, the location of the incident, and the type and severity of the emergency.
Memory Recall
When testing your memory and recall abilities, the examiners want to see if you're capable of remembering details in crisis situations. This section of some tests may include a story with several parts or a set of instructions that you have to follow correctly.
Multitasking
During the multitasking section of a 911 operator exam, you'll be asked to perform several tasks simultaneously. You might have to answer multiple calls, type and listen at the same time and understand what's being said without missing any information.
Spelling
In addition to typing speed, spelling is also tested during the selection process. Some tests may include a list of basic spelling errors you have to find and correct in a given time.
Some tests might also require entering information into a database or query system by providing exact or partial matches for certain keywords.
Spatial Orientation / Map Reading
Another useful skill for 911 operators is the ability to read a map and figure out where an incident takes place.
On some tests, you may be given a large, detailed map of your area or state with several red dots that represent calls. To pass this section of the test, you have to find all the call locations and type them correctly on a computer keyboard or verbally into a phone.
Learning how to become proficient at reading large-scale maps can help you improve your score in this specific section of the dispatcher exam.
Prioritizing
Public safety dispatchers have to make critical decisions about where they are going to send emergency units and how they're going to organize their teams and resources.
Some tests may include a series of incidents, each with several steps or solutions you should select from. You'll be expected to prioritize the most important tasks and follow proper communication protocols.
Reading Comprehension / Written Comprehension
It's very likely that one or more reading comprehension tests will be administered during your selection process. These written tests are designed to measure how well you understand what you read and determine if you can make quick decisions based on the information provided to you.
Listening Comprehension
Listening comprehension tests can be administered in several ways, but the most popular format is to listen to a recording or a call that represents an actual emergency situation. As you listen, you'll have to answer questions and type your answers into the computer.
Deductive Reasoning
Dispatcher deductive reasoning tests assess how quickly you can make sound judgments based on the information provided to you. The questions may require you to follow a series of steps and answer them in the correct order.
Character Comparison
Character Comparison questions are used as another important tool to assess your decision-making skills. You'll be shown several pairs of characters and have to figure out which of the elements in each pair does not match.
How to Prepare for the 911 Dispatcher Test?
