- Eligibility requires 3,000 EM hours and 75 Category I CME credits, both within six years.
- The initial exam is 120 closed-book multiple-choice questions in two 60-minute blocks at Pearson VUE.
- Cardiovascular, Gastrointestinal/Nutrition, and Pulmonary are the heaviest domains at 9% each.
What the PA-CEM Label Actually Refers To
"PA-CEM" is a shorthand used on this site for one specific credential: the Certificate of Added Qualifications in Emergency Medicine, which holders write as PA-C, CAQ-EM. It is awarded by the National Commission on Certification of Physician Assistants (NCCPA) to physician assistants who have demonstrated added knowledge and experience in emergency medicine.
One clarification matters up front: "PA-CEM" is not NCCPA's own abbreviation. It is a site and reference-table identifier. The official credential name is the CAQ in Emergency Medicine, and that is the name you will see on NCCPA documents, your PAHx profile, and employer paperwork. If you are searching for variations of the term, you may also find our explainers on what PA-CEM stands for and the meaning of PA-CEM.
How a CAQ Differs From Your PA-C
The CAQ supplements your existing PA-C certification; it never replaces it. You must hold a current PA-C to apply, and the CAQ stays valid only while your PA-C and licensure remain current. Think of the PA-C as the generalist foundation and the CAQ as a documented layer of emergency-medicine depth on top of it.
| Feature | PA-C (PANCE pathway) | CAQ in Emergency Medicine |
|---|---|---|
| Purpose | Entry-level, general PA certification | Added qualification in one specialty |
| Taken by | New graduates | Practicing, certified PAs with EM experience |
| Experience requirement | None beyond PA program completion | 3,000 hours of EM PA experience |
| Replaces PA-C? | Not applicable | No, supplements it |
| Validity | Maintained through the PA-C cycle | Ten years while PA-C and licensure stay current |
Who Issues It and Who Tests It
NCCPA is the issuer and runs the official specialty program (see the specialty certificates page at nccpa.net). Initial testing is delivered at Pearson VUE test centers. NCCPA publishes the exam blueprint, the policy documents that govern eligibility and maintenance, and the optional practice exam. When any detail here conflicts with a current NCCPA policy document, the NCCPA document wins; verify before you commit money or dates.
Eligibility: Hours, CME, and Licensure
The CAQ-EM has three core prerequisites, all of which must hold at the time you apply. A fuller walkthrough lives in our PA-CEM requirements guide; the essentials are:
- Certification and licensure: a current PA-C and unrestricted U.S. PA licensure (or unrestricted government-agency practice privileges). Every license you hold must be unrestricted.
- Experience: 3,000 hours of emergency-medicine PA experience within the six years before you attest that the experience requirement has been satisfied.
- CME: 75 emergency-medicine Category I CME credits earned within the six years before application, with at least 25 of them earned in the preceding two years.
The initial CAQ process also carries a six-year completion limit, so your hours and CME windows are not open-ended. Track dates as you accumulate credits; a CME certificate that ages out of the window does not count.
The Attestation and Who Signs It
Beyond the exam itself, the CAQ has non-exam requirements. The central one is an attestation covering procedures and patient cases. It is signed by one of the following:
- a collaborating physician who works in emergency medicine and knows your practice;
- a lead or senior PA who works in emergency medicine and knows your practice; or
- for PAs enrolled in or graduated from a postgraduate program, that program's physician or PA director.
The attestation can be submitted before the exam or within 90 days after score notification. It assesses relevant knowledge and skills; it does not require a separate practical examination. Award of the CAQ requires both an NCCPA passing exam result and completion of these non-exam requirements, so a passing score alone does not finish the process.
Exam Format and Test-Day Rules
The initial exam is 120 multiple-choice questions split into two 60-question blocks, each timed at 60 minutes. That gives two hours of testing time, plus a 15-minute tutorial and a 15-minute break that sit outside the clock.
Test-Day Rules Worth Knowing
- The initial exam is closed book: no personal notes, books, or calculators.
- Once a block is submitted or its time expires, you cannot go back to it.
- Pacing is therefore a skill: roughly a minute per item, with a plan for flagged questions inside each block.
Do not confuse this with the separate online maintenance option for renewal, which has different rules (covered below). The remote, references-permitted format applies to maintenance only, not to the initial exam. For a realistic sense of what that two-hour sprint feels like, see how hard the PA-CEM exam is.
What the Exam Covers: 18 Domains and 10 Task Categories
NCCPA's content blueprint organizes the exam two ways at once: by medical content category and by clinical task. The two are cross-classifications of the same questions, not separate sets of items. Note also that the blueprint's detailed examples are illustrative, not exhaustive, and the domain list is a map of what is tested rather than a ready-made curriculum. Our complete domains guide goes deeper on each area.
The 18 Medical Content Domains
| Domain | Weight |
|---|---|
| Cardiovascular System | 9% |
| Gastrointestinal System and Nutrition | 9% |
| Pulmonary System | 9% |
| Neurologic System | 6% |
| Environmental and Toxicologic Disorders | 6% |
| Traumatic Disorders | 6% |
| Eyes, Ears, Nose, & Throat | 5% |
| Genitourinary System | 5% |
| Musculoskeletal System | 5% |
| Psychobehavioral Disorders | 5% |
| Renal System | 5% |
| Obstetrics and Gynecology | 5% |
| Systemic Infectious Disorders | 5% |
| Procedures and Skills | 5% |
| Emerging Topics and Legal/Ethical Issues | 5% |
| Endocrine System | 4% |
| Hematologic System | 4% |
| Dermatologic System | 2% |
The 10 Task Categories
The same questions are also classified by what you are being asked to do. These are not extra medical domains:
- History Taking and Performing Physical Examination: 15%
- Ordering and Interpreting Diagnostic and Laboratory Studies: 15%
- Formulating Most Likely Diagnosis: 16%
- Clinical Intervention: 16%
- Pharmaceutical Therapeutics: 15%
- Applying Scientific Concepts: 7%
- Patient Education and Preventive Measures: 5%
- Emerging Topics and Legal/Ethical Issues: 5%
- Cultural Competency and Social Determinants of Healthcare: 3%
- Public Health (Population/Society): 3%
Read that list as a clue to question style. Roughly three-fifths of the exam sits in diagnosis, intervention, workup, and pharmacology tasks, which means most items ask you to decide what you would do or conclude in a presentation, not simply recall a fact.
Key Takeaway
Cross-reference the two views. A cardiovascular question is simultaneously a Domain 1 item and, say, a "Formulating Most Likely Diagnosis" or "Pharmaceutical Therapeutics" item. Study cardiovascular, GI, and pulmonary presentations through all three lenses: recognize, work up, treat.
Costs, Scores, and Timeline
The initial fee is $350 total: a $100 registration/administration charge plus a $250 examination fee. Our certification cost breakdown covers add-ons you may want to budget for, such as CME and review materials. NCCPA also sells an optional practice exam for $50. It is a single form for this specialty with a 180-day completion window, and NCCPA states that its educational feedback does not predict whether you will pass.
Scores are generally released eight to ten weeks after administration, following validation. As for the passing threshold, a numeric cut score and an official specialty-specific pass rate were not verified for this article, so treat any commercial claim of a precise pass rate or a pass guarantee with skepticism. Our pages on the passing score and pass rate explain what can and cannot be said responsibly. For scheduling questions, see exam dates and testing windows.
Keeping the CAQ: The Ten-Year Cycle
The CAQ runs ten years, provided your PA-C and licensure stay current. Renewal has two pieces:
- 125 specialty Category I CME credits earned within the cycle and submitted by the time of the maintenance-exam application.
- A passing specialty exam. Under the May 2026 governing policy, you get three maintenance attempts across years nine and ten.
There is also a separate online maintenance option: 120 questions, a five-minute limit per question, and about six weeks to finish. References are permitted, but collaboration is not. This is a maintenance format only and should never be mistaken for a remote, open-book route to the initial CAQ.
Sequencing Your Preparation by Domain
Generic study habits matter less than where you aim your hours. A defensible sequence for an experienced EM PA follows the weights and your own gaps. For a fuller plan, see the PA-CEM study guide.
The 9% Trio
- Cardiovascular: ACS, arrhythmias, aortic emergencies, heart failure
- Pulmonary: PE, asthma/COPD exacerbation, pneumothorax, respiratory failure
- Gastrointestinal and Nutrition: acute abdomen, GI bleeding, pancreatitis, biliary disease
The 6% Group
- Neurologic: stroke, seizure, headache red flags
- Environmental and Toxicologic: overdoses, antidotes, heat and cold injury
- Traumatic Disorders: primary and secondary survey logic
Breadth and Procedures
- The 5% systems, including OB/GYN, renal, infectious disease, and psychobehavioral
- Procedures and Skills: indications, contraindications, complications
- Legal/ethical topics such as consent, capacity, and EMTALA-type obligations
Because the exam is closed book and heavy on diagnosis and intervention, practice with timed blocks of 60 questions in 60 minutes, and use the optional NCCPA practice exam as a format check, not a pass predictor. Our one-page cheat sheet works as a final-week refresher, and you can build question stamina with the practice tests on the main practice test site.
Who Pursues It and Where It Fits
The CAQ-EM is aimed at PAs who already work in emergency departments, urgent care settings with high acuity, or related emergency-medicine roles and who want a formal, portable credential for that experience. Because the experience hurdle is 3,000 hours, candidates are typically established clinicians rather than new graduates.
Be careful with the money question. This article does not claim that holding the CAQ causes a pay premium, and none should be assumed. Employers value specialty credentials differently, and some weigh the CAQ in hiring, credentialing, or promotion while others weigh experience alone. Before investing, check how your own employer and region treat it, then see our discussions of earnings, job opportunities, and whether the certification is worth it. If you came here for a short definition instead, our PA-CEM certification overview is the quick version.
Frequently Asked Questions
No. The PANCE is the entry-level exam for general PA certification. The CAQ in Emergency Medicine is a separate specialty credential for already-certified PAs, and it supplements rather than replaces your PA-C.
A current PA-C, unrestricted U.S. licensure, 3,000 hours of EM PA experience, and 75 EM Category I CME credits within six years, including at least 25 in the last two. The attestation can follow the exam by up to 90 days.
It has 120 multiple-choice questions in two 60-question, 60-minute blocks, taken at a Pearson VUE center. The initial exam is closed book: no notes, books, or calculators, and submitted blocks cannot be revisited.
The initial fee is $350 total, made up of $100 registration/administration and $250 for the examination. The optional NCCPA practice exam is an additional $50.
The CAQ lasts ten years while your PA-C and license remain current. Renewal requires 125 specialty Category I CME credits and a passing specialty exam, with three maintenance attempts available in years nine and ten.
