PA-CEM Exam Domains 2026: Complete Guide to All 18 Content Areas

What the Blueprint Actually Covers

The Certificate of Added Qualifications in Emergency Medicine (designated PA-C, CAQ-EM) is issued by the National Commission on Certification of Physician Assistants (NCCPA). It supplements your existing PA-C certification rather than replacing it. If you want the credential-level background first, see What Is PA-CEM Certification? and What Does PA-CEM Stand For?. A quick note on naming: "PA-CEM" is the identifier used on this site, while NCCPA's official designation is PA-C, CAQ-EM.

This article walks through the 18 medical content categories on NCCPA's Content Blueprint for the Emergency Medicine CAQ Examination, an eight-page document hosted by the issuer. Two points about how to read it:

• The 18 domain lines are medical content categories, not a preparation curriculum. They tell you what questions can draw from, not a recommended reading order.
• The detailed examples listed under each domain on the blueprint are illustrative, not exhaustive. A topic missing from an example list can still appear.

This exam is not the PANCE, not an emergency-medicine end-of-rotation exam, and not an ABEM physician-board examination. Question banks built for those tests will overlap in content but not in framing. For the broader preparation plan, pair this guide with the PA-CEM Study Guide.

The 18 Domains by Weight

Here is the full distribution from the retrieved issuer-hosted blueprint, sorted by weight so you can see where the points sit.

On a 120-question exam, percentages translate into rough question counts, but treat any such arithmetic as an approximation. Blueprint weights describe the intended content mix, and NCCPA does not promise an exact count per domain on any single form.

The Three 9% Systems: Where Points Concentrate

Cardiovascular, Gastrointestinal System and Nutrition, and Pulmonary share the top allocation. Together they account for 27% of the blueprint, which is more than a quarter of the exam from three systems. For an emergency-medicine PA, this lines up with the undifferentiated chest pain, abdominal pain, and dyspnea presentations that dominate real ED volume.

Mid-Weight Domains: Neuro, Environmental, Trauma, and More

The 6% tier

Neurologic System (6%) covers stroke and TIA recognition, seizures and status epilepticus, intracranial hemorrhage, headache red flags, meningitis and encephalitis, and altered mental status. Time-sensitive decision points, such as eligibility windows for acute stroke therapy, are classic question fodder.

Environmental and Toxicologic Disorders (6%) is where EM separates itself from general primary-care PA content. Expect heat and cold injury, drowning, envenomations, burns, and the full spectrum of overdoses and poisonings, including antidotes and when to use them. Toxidromes are high yield because they let a single clinical picture drive a single answer.

Traumatic Disorders (6%) includes primary and secondary survey logic, head, spine, thoracic, and abdominal trauma, and hemorrhage control. This domain also intersects with Musculoskeletal and Procedures and Skills, so a single scenario can touch several blueprint lines.

The 5% tier

Nine domains sit at 5%: Eyes, Ears, Nose, & Throat; Genitourinary; Musculoskeletal; Psychobehavioral Disorders; Renal; Obstetrics and Gynecology; Systemic Infectious Disorders; Procedures and Skills; and Emerging Topics and Legal/Ethical Issues. Individually they look small, but together they make up 45% of the exam. Ignoring them because none is large is a common planning mistake.

Lighter Domains That Still Cost You Points

Endocrine (4%), Hematologic (4%), and Dermatologic (2%) are the smallest content lines. They are also the easiest to over-trim from a study plan, so be deliberate.

• Endocrine: DKA and hyperosmolar states, hypoglycemia, thyroid storm, adrenal crisis. These are acute-management topics, so the emphasis is recognition and stabilization, not long-term titration.
• Hematologic: sickle cell crisis, anticoagulant reversal, transfusion decisions, thrombocytopenic emergencies. Reversal agents and their indications are a compact, high-yield set.
• Dermatologic: at 2%, the lowest weight, but dangerous rashes (necrotizing infections, SJS/TEN, meningococcemia-type presentations) still reward quick recognition.

A sensible approach is a compact, targeted pass through these three, not zero coverage and not deep dives. For related decisions about how hard the exam is overall, see How Hard Is the PA-CEM Exam?.

The Ten Task Categories Cut Across Every Domain

The blueprint also weights the exam by task, meaning the kind of thinking a question asks you to do. These ten categories classify the same questions a second way. They are not additional medical domains, and the percentages should not be added to the domain weights.

In practice, one question might be a Pulmonary domain item that tests Pharmaceutical Therapeutics. Another might be a Cardiovascular item that tests Ordering and Interpreting Diagnostic Studies. When you review a missed question, tag it twice: by domain and by task. Over time you will see whether your errors cluster by system or by skill, which changes what you should fix. The PA-CEM Cheat Sheet condenses many of these decision points into one page.

Exam Format and Logistics That Shape How You Study

The blueprint tells you what is tested; the test-day rules tell you how you will experience it.

• Length and timing: 120 multiple-choice questions in two 60-question blocks of 60 minutes each. Two hours is the testing time; a 15-minute tutorial and a 15-minute break are additional.
• Closed book: no personal notes, books, or calculators at the initial exam.
• No revisiting submitted blocks: once a block is submitted or its time expires, you cannot return to it. Pace for roughly one minute per question and flag sparingly.
• Delivery: initial testing takes place at Pearson VUE test centers.
• Fees: USD $350 total, split into $100 registration/administration and $250 examination. A full cost picture is in PA-CEM Certification Cost.
• Eligibility: current PA-C, unrestricted U.S. licensure or government-agency privileges, 3,000 hours of emergency-medicine PA experience within six years, and 75 emergency-medicine Category I CME credits within six years (at least 25 within the preceding two years). Details are in PA-CEM Requirements.
• Scoring: scores are generally released eight to ten weeks after administration following validation. A numeric passing threshold and an official specialty-specific pass rate were not verified, so see PA-CEM Passing Score and PA-CEM Pass Rate for how to think about what is and is not known.

The closed-book rule matters for the Pharmaceutical Therapeutics and Procedures and Skills content. You cannot look up a reversal agent or a dosing range, so those facts must live in memory. The separate online maintenance option for renewal permits references, but that policy applies to maintenance exams, not the initial CAQ exam. For scheduling specifics, check PA-CEM Exam Dates.

A Version Caveat You Should Not Ignore

The distribution in this article comes from the issuer-hosted file EM-CAQ-Blueprint.pdf, which is undated. The specialty page also links a legacy blueprint file that could not be retrieved at the time of checking. Publicly visible reproductions of older blueprints use different headings and weights, including 10% for the largest systems and 2% for Procedures and Skills. Those older numbers differ from the ones above.

In practical terms, the rank order is stable enough to plan with: the big three systems first, then the 6% tier, then the broad 5% band, then the small domains. The exact percentage points are what you should verify.

Scheduling the Domains Across Your Prep

Here is one way to sequence the 18 domains over a compact plan, tied to weight and to how much each area interacts with others. Adjust the length to your timeline and your clinical strengths.

The official optional NCCPA practice exam costs $50, offers one form for this specialty, and has a 180-day completion window. NCCPA notes that its feedback is educational and does not predict an exam pass, so use it to check format familiarity and domain-level gaps, not as a score forecast. For a fuller preparation framework, return to the PA-CEM Study Guide, and use our practice test platform to drill the high-weight systems under timed conditions.
