What Is OPA-C Certification?

What the OPA-C Credential Actually Is

OPA-C stands for Orthopaedic Physician's Assistant Certification. Successful candidates are awarded the title Orthopedic Physician Assistant-Certified, and the 2026 candidate handbook uses that wording. It is a credential built around one clinical specialty: assisting orthopedic surgeons with the evaluation, surgical care, and nonoperative management of musculoskeletal patients.

Because several credentials in healthcare share similar abbreviations, it helps to be precise about what this one is not. It is not the OA-C credential, it is not the NCCPA's PA-C, and it is not an Orthopaedic Surgery CAQ. Each of those is governed by a different body with different rules. If you have read about another credential and assumed the details transfer, they do not. Everything on this page applies only to the NBCOPA certification examination.

If you are comparing short-form explanations of the abbreviation, our pages on what OPA-C stands for and the meaning of OPA-C cover the naming question briefly. This article goes further into how the credential works.

Who Certifies, Who Administers, and Who Doesn't

Three different organizations appear in the OPA-C story, and mixing them up is common.

The practical consequence: when you need an authoritative answer about eligibility, deadlines, or fees, go to the NBCOPA candidate handbook and the PTC sponsor page rather than to an association's older materials. Older web pages exist that describe different question counts, time limits, and scheduling arrangements, so always confirm which edition of the handbook you are reading.

Exam Format at a Glance

The certification examination consists of 200 multiple-choice objective questions, with 3 hours 15 minutes of testing time. That works out to a little under a minute per question, so pacing matters more than most candidates expect. The exam is computer-based and closed-book, delivered at Prometric centers during fixed testing windows rather than on demand.

There are no scheduled breaks. You may be permitted to step away, but the timer does not pause while you do. Plan your hydration and logistics before you walk in rather than counting on a convenient pause.

Questions are objective and multiple-choice, so the skill being tested is recognition and clinical reasoning across a broad specialty, not essay writing or procedural demonstration. For a candid look at how that format feels in practice, see how hard the OPA-C exam is.

The Five Content Domains

The exam is organized into five formal domains with published percentage weights totaling 100%. These are exam objectives, not course topics, so they tell you what will be sampled rather than how a school sequences its curriculum. The two largest domains together account for 60% of the exam.

Eligibility: Three Education Pathways

Candidates must be legal U.S. residents at the time of application and at the time of testing. Beyond that, eligibility runs through one of three education pathways:

1. Program completion: completion of an orthopedic physician assistant program, a primary-care PA program, or an NP program.
2. Master's-level orthopedic assisting: completion of a master's-level orthopedic-assisting program.
3. Allied-health plus experience: completion of a related allied-health program plus five years of orthopedic work, including surgical assisting, history and physical assessment, and immobilization, under a board-certified orthopedic surgeon.

The five-year work requirement belongs to the third pathway only; it does not apply to every candidate. All pathways require evidence of program completion and a signed verification from the supervising board-certified orthopedic surgeon. Two years of college science are recommended but not mandatory.

Fees, Windows, and Deadlines

Fee structure

The initial certification fee is US$450. Recertification by examination is US$350, which includes testing-center fees and a US$75 non-refundable administrative component. Two other charges are worth knowing because they are easy to confuse with routine fees: US$50 for permitted rescheduling 29 to 5 days before an appointment within the same window, and US$215 for a one-time transfer to a new testing period. These are separate transactions, not extra costs every candidate pays. For a full breakdown, see the OPA-C certification cost guide.

Published 2026 windows

As of October 15, 2026, the final 2026 window is in progress and its application deadline has passed. The next published window falls February 20 to March 6, 2027, with a January 20, 2027 application deadline. Because windows are the only way to sit the exam, missing a deadline means waiting for the next one. The OPA-C exam dates page tracks scheduling in more detail.

Test-Day Rules and Results

Test-day conditions are strict and worth reading in advance:

• Closed-book testing; no unauthorized references or electronics during the exam or during any break.
• A valid government-issued photo ID that matches your registration.
• A confidentiality agreement you must accept.
• No scheduled breaks, and permitted breaks do not stop the clock.

If you need testing accommodations, requests are due at least eight weeks before the testing window opens, so decide early.

PTC reports pass/fail along with content-area and total scores roughly four weeks after the testing window closes. No public numeric passing threshold or current cohort pass rate was verified in the 2026 sources, so be skeptical of any site quoting a precise cut score or pass percentage. Our pages on the passing score and pass rate explain what is and is not known.

Sequencing Your Preparation Around the Weights

The domain weights suggest an order of attack. This is one way to allocate an eight-week plan; adjust it to your own background.

Conditions and treatment come first among the heavy domains because they are interdependent: you cannot reason about management without recognizing the diagnosis. For a fuller plan, see the OPA-C study guide, and for quick last-minute review, the one-page cheat sheet.

About practice materials

An optional official practice product exists: 75 items for US$75. It is not the 200-question certification exam, and it does not provide an individual answer key, answer rationales, or item-level correctness review. Its score report is not a validated predictor of how you will perform on the real exam. The issuer's older materials state that no official study guide exists, so any independent study book or question bank, including the practice questions at our main practice test site, should be understood as independent preparation rather than issuer-endorsed content.

Keeping the Credential: The Four-Year Cycle

Certification lasts four years. At renewal you can recertify either by sitting the current examination again or by documenting 120 CME hours, with at least 50% orthopaedic-related and at least 40 Category I hours.

• Deadline: CME submission is due October 31 of the renewal year. A late fee of US$100 applies. Older TCOPA pages cite an October 1 deadline, which should not be relied on.
• Processing fees: US$2 per credit for eligible NAOT or approved OPA-organization members, US$5 per credit for non-members. For 120 credits, the base totals are US$240 for members and US$600 for non-members.
• Checkout detail: the listed member TCOPA/NAOT PayPal checkout adds US$10, bringing the member total to US$250.

The member-versus-non-member gap is large enough that membership can pay for itself over a renewal cycle, depending on what the membership costs you. Confirm current numbers directly with NBCOPA before budgeting.

Where the Credential Fits in Practice

OPA-C professionals work where orthopedic surgeons work: orthopedic surgery practices, hospital orthopedic and trauma services, sports medicine clinics, and surgical settings where first-assistant skills and immobilization expertise are in demand. The credential signals specialty-specific competence in orthopedic assisting, which is why the third eligibility pathway is built around years of surgeon-supervised orthopedic work.
