In Colorado, EMTs must pass the cognitive National Registry of Emergency Medical Technicians (NREMT) exam. The cognitive exam is a computer-based adaptive test, which means that the difficulty of the questions adjusts based on the number of correct answers given.
A test-taker will answer between seventy and 120 questions to meet Colorado EMT certification requirements. The testing system will stop when it’s 95% confident that you passed or failed. The number of questions depends on your performance, so the number of correct questions needed to pass can vary from one person to another.
What Is a Computer-Adaptive Test?
A computer-adaptive test uses algorithms to adjust the difficulty of questions based on whether previous answers were correct or incorrect. Adjustments are made in real-time to provide a more accurate and efficient measurement of an individual’s abilities and depth of knowledge about emergency medical services.
As the test-taker progresses through the exam, the computer continuously reevaluates their abilities to select a question that it believes the candidate has a 50% chance of answering correctly. Once the NREMT system is 95% certain that you have the knowledge and skills necessary to be an EMT, the test stops.
Scores from adaptive tests are not based on the number of correct answers. They are based on the level of difficulty of the questions that the test-taker can answer correctly. Because each test is tailored to the individual test-taker, this approach is considered more secure and fair than traditional test formats. It also helps prevent cheating.
What Does the NREMT Cognitive Exam Cover?
The main categories covered by EMT examination are: scene size-up and safety, primary assessment, secondary assessment, patient treatment and transport, and operations.
Knowledge assessed by the test encompasses a broad range of topics related to emergency medical care, including airway, respiration, and ventilation; cardiology and resuscitation; trauma; medical, obstetric, and gynecologic care; and operations. Approximately 85% of the questions will be related to emergency medical services for adult patients, and 15% will be related to pediatric patients.
Candidates have two hours to complete the EMT exam, although it may take less time to demonstrate that you are qualified to be an EMT. The NREMT does not make any recommendations on what study materials help for Colorado EMTs, so make sure you find resources that cater to your learning style and schedule.
Register for the Test in Advance
All NREMT test-takers need an Authorization to Test before they can take the exam. To receive authorization, you must complete an application on the NREMT website and pay the application fees. Your program director must also verify your eligibility.
It usually takes one to two days for the authorization to be posted to your NREMT account, although this can take longer depending on the volume of requests. The Authorization to Test is only valid for ninety days from the date it is posted to your account, and no extensions are allowed.

If you pass the NREMT exam and meet all additional requirements for the role (e.g., criminal background checks, age restrictions, etc.), the State of Colorado will issue a three-year certificate after you apply to the Department of Public Health and Environment (CDPHE). EMT candidates must create an OATH account with CDPHE to start the Colorado application process.
