NREMT EMT Exam Content Outline: the 5 domains and what each one tests
By Rounds EMS
Updated September 28, 2026 · 10 min read
Always follow your local protocols. The exam tests national, entry-level practice, and your state, agency and medical director may set different steps or limits. This guide is for exam study; your protocols decide what you do on a call.
Scene Size-Up and Safety, Primary Assessment, Secondary Assessment, Patient Treatment and Transport, and Operations. Since April 7, 2025, those five domains are the whole NREMT EMT exam, and Primary Assessment alone is 39–43% of it. The old chapters, airway, cardiology, trauma and medical, are gone as domains.
The 5 domains on one chart
The share of the exam comes from the National Registry’s EMT test plan. Each Rounds question is tagged to the domain it tests.
| Domain | Share of the exam |
|---|---|
| Scene Size-Up and Safety | 15–19% |
| Primary Assessment | 39–43% |
| Secondary Assessment | 5–9% |
| Patient Treatment and Transport | 20–24% |
| Operations | 10–14% |
The share is a range because every exam is built to fit inside it.
What changed in April 2025
The National Registry switched the EMT exam to the new outline on April 7, 2025. The last day to take the old version was April 4, 2025. The new domains come from a 2023 study of what working EMTs actually do on the job.
- Airway, Respirations, and Ventilation
- Cardiology and Resuscitation
- Trauma
- Medical, Obstetrics, and Gynecology
- Operations
- Scene Size-Up and Safety
- Primary Assessment
- Secondary Assessment
- Patient Treatment and Transport
- Operations
Only Operations kept its name. Airway, cardiology, trauma and medical content now shows up inside the phases of the call.
What stayed the same, per the National Registry:
- Length. 70 to 120 questions, 10 of them unscored pilot questions you cannot pick out, in 2 hours.
- Format. A computerized adaptive test at a Pearson VUE center or online through OnVUE. It can stop at 70 questions once it is 95% confident of a pass or fail.
- Difficulty. The National Registry says it does not expect any change in difficulty.
The question formats did grow. Besides standard multiple choice, the test plan lists multiple response (pick 2 of 5, or 3 of 6), options tables, build list (put steps in order) and drag-and-drop. Every item is all or nothing: no partial credit. For the full exam day, see how the NREMT EMT exam works.
Where airway, cardiology, trauma and medical went
They did not leave the exam. They moved inside the job tasks. The test plan lists those tasks under each domain, and the clinical words sit right there:
- Primary Assessment lists assessing the airway, breathing and circulation, and finding the chief complaint and life threats.
- Patient Treatment and Transport lists managing the airway, ventilation and oxygenation, the cardiovascular and circulatory system, motion restriction of the musculoskeletal system, giving medication, and care for special populations.
- Pediatrics has no domain of its own. The National Registry says items related to pediatric patient care are integrated throughout the exam.
So one chest pain patient can land in several domains. Is the scene safe? Scene Size-Up. Is the patient perfusing? Primary Assessment. What did the history reveal? Secondary Assessment. When does aspirin go in? Treatment and Transport. The domain is set by the step of the call being tested, not by the illness. That is why the assessment order you learned for the trauma assessment and medical assessment skill stations matters on the written exam too.
Scene Size-Up and Safety
15–19% of the exam
- What it covers
- Planning before you arrive from dispatch information, protecting yourself, other responders, the patient and the public from hazards, choosing PPE for the known hazard, finding how many patients there are, triage, and calling for the resources the scene needs.
- In a question
- A scene with a clue that should stop you: a smell, an unsecured dog, a car still in gear, a second victim nobody mentioned. Or a crash with more patients than your crew can handle.
- How to study it
- For every scenario, ask four questions before touching the patient. Is it safe? What PPE? How many patients? What help do I need? Say them in that order until it is automatic.
Exam trap: the answer that starts patient care is often wrong because it skips a hazard in the first sentence of the stem. Read the scene before you read the patient.
Primary Assessment
39–43% of the exam
- What it covers
- Building rapport, the general impression, level of consciousness, airway, breathing, circulation, the chief complaint and life threats, baseline vital signs and diagnostic results, and deciding on rapid treatment, rapid transport or more resources.
- In a question
- A patient with several problems at once, and the question asks what you do first. Or a set of vital signs and skin findings, and you decide if the patient is sick or stable.
- How to study it
- Drill priorities, not facts. Take any scenario and name the single biggest threat to life, then the one step that fixes it. This is the largest domain, so it earns the largest share of your practice.
Exam trap: a detailed answer that belongs later in the call. A full history or a head-to-toe exam is the wrong choice while the airway or breathing is still a problem.
Secondary Assessment
5–9% of the exam
- What it covers
- The focused physical exam, the patient interview and past medical history, and reassessment: rechecking earlier findings and treatments to see if the patient has changed.
- In a question
- A second set of vital signs that differs from the first. A history detail that changes the picture. You interpret the trend.
- How to study it
- Practice reading two sets of findings side by side and naming the direction: better, worse or the same. The trend matters more than any single number.
Exam trap: a small domain is not a skippable one. Reassessment is how you catch a patient getting worse, and it feeds straight into the treatment and transport decisions that follow.
Patient Treatment and Transport
20–24% of the exam
- What it covers
- Managing airway, ventilation and oxygenation, the heart and circulation, motion restriction, giving medications, care for special populations, transport, and handing off patient information.
- In a question
- The patient is assessed and the problem is clear. Now pick the intervention, the device, the drug decision, or where and how fast to transport.
- How to study it
- Learn each treatment as a decision: when to do it, when to hold it, and what to check after. Our EMT medications guide lays out the drugs this way.
Exam trap: the right treatment for the wrong patient. The stem usually hides one detail, like a low blood pressure or a patient who cannot swallow, that turns a correct intervention into the wrong answer.
Operations
10–14% of the exam
- What it covers
- Keeping equipment in working order, keeping enough medications and supplies stocked, completing proper documentation, and looking after your own well-being and that of other responders.
- In a question
- A problem that is not about the patient’s body: a failed equipment check, a missing supply, a chart that needs correcting, a partner showing signs of stress after a hard call.
- How to study it
- Know the reason behind each routine. Why you check the equipment before the shift, why documentation must be accurate, why crew stress is your problem too.
Exam trap: treating Operations as common sense. These are scored questions, and the answer is the one that follows the proper process, not the one that gets the job done fastest.
How to split your study time
The percentages tell you where the exam spends its questions. Use them as your plan.
- Start with Primary AssessmentAt 39–43%, it is close to half the exam. Get fast at spotting the first life threat.
- Then Treatment and TransportAt 20–24%, it is the second largest. Pair every treatment with its reason to hold.
- Then Scene Size-Up and SafetyAt 15–19%, it is the third largest domain. Build the four-question habit.
- Then OperationsAt 10–14%, it covers equipment, supplies, documentation and crew well-being.
- Keep reassessment sharpSecondary Assessment is 5–9%, but reading a trend is a skill every other domain leans on.
A real Secondary Assessment question
During reassessment of a medical emergency patient, you note that the skin has become cool and mottled, the radial pulses are now weak, and the heart rate has increased from 98 to 122 beats/min. What is the BEST interpretation of these findings?
- The patient is experiencing pain-related anxiety.
- The patient is compensating appropriately for the illness.
- The patient’s condition is unchanged from the initial assessment.
- The patient’s perfusion status is deteriorating.
Show the answer
D. The patient’s perfusion status is deteriorating. Three findings moved in the same direction: the heart rate climbed from 98 to 122, the radial pulses went weak, and the skin turned cool and mottled. The body is pulling blood away from the skin and limbs to protect vital organs. Together, that means perfusion is getting worse. Now you reassess for shock, check whether your treatment is working, and consider faster transport.
B is the tempting one. The faster heart rate is the body compensating, but all three findings got worse since the last check. That is not “appropriate.” It means the patient is heading toward decompensated shock. A is wrong because anxiety can raise the heart rate but does not explain weak pulses or mottled skin. C is wrong because all three findings changed, which is the exact thing reassessment exists to catch.
Read the direction of the findings together, not one number alone.
Frequently asked questions
What are the five domains on the NREMT EMT exam?
Scene Size-Up and Safety (15–19%), Primary Assessment (39–43%), Secondary Assessment (5–9%), Patient Treatment and Transport (20–24%), and Operations (10–14%).
How many questions are on the NREMT EMT exam?
Between 70 and 120, including 10 unscored pilot questions you cannot tell apart from the rest. You have 2 hours.
Is the EMT exam still split into airway, cardiology, trauma and medical?
No. Those were the domains until April 4, 2025. Since April 7, 2025, the exam is organized by the phases of a call. Airway, cardiac, trauma and medical care still appear, inside the job tasks of the new domains.
Are there pediatric questions on the NREMT EMT exam?
Yes. Pediatrics has no domain of its own. The National Registry says items related to pediatric patient care are integrated throughout the exam.
Did the new outline make the EMT exam harder?
The National Registry says it does not expect any change in difficulty. The length, the 2-hour limit and the adaptive format stayed the same. The question formats grew to include build list, drag-and-drop and options tables.
