PA-COS Passing Score 2026: Exactly What You Need to Pass

What "Passing" Means for the Orthopaedic Surgery CAQ

If you are searching for a single magic number, start by resetting expectations. The credential behind "PA-COS" on this site is the Certificate of Added Qualifications in Orthopaedic Surgery (CAQ-OS), issued by the National Commission on Certification of Physician Assistants (NCCPA) and held alongside your PA-C. Passing means clearing the performance standard NCCPA sets for this specialty examination. It is not a percent-correct figure you can calculate on a calculator while you study.

That distinction matters because many candidates arrive from the PANCE, where the conversation revolves around scaled scores. Before you plan your preparation around any numeric target, read the rest of this article for what is and is not publicly documented. For the broader picture of who qualifies to sit for the exam, see our guide to PA-COS requirements, eligibility, and prerequisites.

What NCCPA Does and Does Not Publish About Scoring

Being honest about the limits of the public record is more useful than repeating folklore. In the source material used for this article, NCCPA's published documents describe the exam's structure, content blueprint, fees, prerequisites, and test-day procedures. They do not give us a verified raw-score cutoff or a stated percentage of correct answers needed to pass. We will not invent one.

Here is what that means in practice:

• No safe "number of questions" target. You cannot reliably convert "I need X out of 120" from public information, so any forum claim of a hard cutoff should be treated as unverified.
• No pass-rate figure is cited here. We do not quote one because none is documented in our source set. For what is and is not known, see our write-up on the PA-COS pass rate.
• The practice exam is not a predictor. NCCPA states its practice exam does not predict passing, which means even a strong practice result is only a rough signal.

The practical conclusion: your target should be breadth and depth against the blueprint, not a magic percentage. A candidate who is solid across all nine content categories is far safer than one who is brilliant in fractures and blind in spine and pediatrics.

Exam Format That Shapes Your Score

Your score is produced under specific conditions, and those conditions influence how you should answer. The exam is delivered at Pearson VUE test centers and consists of 120 multiple-choice questions split into two blocks of 60 questions, each timed at 60 minutes. That is two hours of testing, plus a separate 15-minute tutorial and a separate 15-minute break.

Why the Block Rule Changes Your Pacing

Because review is limited to the active block, you can flag and revisit questions only within the 60 you are currently answering. Once you submit the block, those answers are locked. Practically, that means you should budget about a minute per question, mark genuinely uncertain items, and use any leftover time before the block ends rather than rushing. Do not leave a hard question blank assuming you will return to it after the break. For a fuller look at how demanding the format feels, see how hard the PA-COS exam is.

Where the Points Live: Blueprint Weights

NCCPA's Content Blueprint for the Orthopaedic Surgery CAQ Examination defines nine weighted Medical Content Categories. The blueprint is an undated document that the issuer says is based on the 2023 PA Practice Analysis. Since your exam is a sample of these categories, the weights tell you how much of your result each area can influence.

Three categories account for 70% of the exam: Fractures/Dislocations, Soft-Tissue Injuries and Disorders, and Joint Disorders. For a deeper walk through each area, read our complete guide to all nine PA-COS content areas.

The smaller categories are not throwaways. Combined, Preoperative/Postoperative/Complication Management (7%), Spine (7%), Bone Tumors (5%), Infectious Diseases and Connective Tissue Disorders (5%), Pediatric (4%), and Professional, Legal, and Ethical Issues (2%) make up 30% of the exam. Ignoring them is a strategic risk, particularly because a marginal result can hinge on a cluster of questions you skipped studying.

Task Categories: The Second Lens on Every Question

The same blueprint also classifies each question by what you are asked to do. These Task Categories overlap with the content areas rather than adding new ones, so do not add them to the nine weights above.

Read this table alongside the content weights. A question might be a Joint Disorders item that asks you to choose a treatment, or a Fractures item that asks you to interpret imaging. Roughly half of the exam asks you to commit to a diagnosis or a treatment, so studying isolated facts without practicing "given this presentation, what is the next best step" will leave you underprepared.

Fees, Attempts, and Eligibility Before You Test

Before you worry about a score, make sure you can sit for the exam at all. The initial CAQ pathway costs $350 total, made up of a $100 program registration and a $250 examination fee. You have six years to complete the initial requirements, and if you need another examination attempt within that period, it costs $250. For a full breakdown, see our PA-COS certification cost guide.

Prerequisites include:

• A current PA-C credential
• Unrestricted PA licensure in a US jurisdiction or territory, or unrestricted government practice privileges; all licenses you hold must be unrestricted
• 4,000 hours of orthopaedic surgery specialty experience within the preceding six years
• 75 Category I CME credits in the specialty over six years, including 25 in the preceding two years
• ACLS is recommended but not mandatory
• An attestation from a specialty physician, lead/senior PA, or physician/PA postgraduate program director familiar with your work, covering relevant procedures and patient-case experience, due within 90 days of your score report

Building a Score Strategy Around the Blueprint

With no published numeric cutoff to chase, the most defensible plan is weighted coverage. Allocate preparation time roughly in proportion to the blueprint, then add extra time to areas where your daily work gives you the least exposure. A surgical PA in a sports-medicine practice, for example, may be strong in soft tissue and weaker in pediatrics, spine, or tumors.

One compact sequencing idea, tied directly to the weights:

Using the NCCPA Practice Exam Without Misreading It

NCCPA offers a separate practice examination for $50. It contains 60 questions, runs for 60 minutes, and gives you 180 days of access. Two caveats from the issuer matter for how you interpret results: it does not provide item-by-item explanations, and it does not predict whether you will pass.

That makes it a format rehearsal rather than a scoreboard. Use it to practice the timing of a single 60-minute block and to see the style of the questions. Then pair it with resources that do explain answers. NCCPA's free sample preparation questions come with critiques that explain the reasoning, so they are better for learning why an answer is right.

When you are ready for additional timed practice that includes explanations, you can work through questions on our PA-COS practice test platform and track your performance by content category rather than by a single overall number.

After You Pass: Validity and Maintenance

Once earned, the CAQ is valid for ten years. To keep it, you must maintain your PA-C and unrestricted licensure, earn 125 specialty Category I CME credits during the cycle, and pass a maintenance examination. The maintenance-only online option is open-reference with 120 questions and five minutes per question, with an approximately six-week completion window. Those are maintenance rules, not initial exam rules.
