  • Initial fee is US$450; permitted rescheduling is US$50 and a one-time transfer to a new testing period is US$215.
  • Certification lasts four years; renew by reexamination or 120 CME hours, with submission due October 31 of the renewal year.

Identity Check: Which OPA-C This Cheat Sheet Covers

The acronym "OPA-C" is used by more than one credential, so start by confirming you are studying the right one. This page covers Orthopaedic Physician's Assistant Certification, awarded as Orthopedic Physician Assistant-Certified under the 2026 candidate handbook. The certifying authority is the National Board for Certification of Orthopaedic Physician's Assistants (NBCOPA, also written NBCOA). Professional Testing Corporation (PTC) administers the examination, and Prometric delivers it at computer-based test centers during published testing windows.

Three look-alikes are worth separating from this credential:

  • OA-C is a different orthopaedic assistant credential, not this one.
  • NCCPA's PA-C is the general physician assistant certification, not this one.
  • An Orthopaedic Surgery CAQ is a different type of specialty recognition.

The professional association ASOPA/ASOA is also separate from the certifying board. PTC states that ASOA dissolved while NBCOPA certification continues. If you are new to the terminology, our explainers on what OPA-C certification is and what OPA-C stands for cover the basics before you dive into the details below.

The pacing math matters. Across 200 questions in 195 minutes, you have a little under one minute per item. That is comfortable for recall-based items and tight for clinical scenarios that require you to read a history, interpret an imaging description, and choose the next management step. Any break you take comes out of your own time because the clock keeps running.

One point to be careful about: the 2026 handbook does not publish a numeric passing threshold, and no current cohort pass rate was verified in the retrieved 2026 sources. Treat any specific cutoff or pass-rate figure you find in forums with suspicion. Our pages on the OPA-C passing score and the OPA-C pass rate explain what can and cannot be stated responsibly.

Source conflict to know about: An older NBCOPA Board Certification page describes up to 250 questions, four hours, a different testing vendor, as-needed scheduling, and different domain weights. Those details conflict with the dated 2026 handbook. This cheat sheet follows the 2026 handbook: 200 questions, 195 minutes, and the published testing windows below. If you see 250 questions or four hours quoted somewhere, you are looking at outdated information.

Domain Weights and What They Mean for Your Time

The five formal exam domains and their published weights total 100%. These are exam objectives, not course topics, so you should expect questions to cut across what you learned in separate classes.

DomainWeightApproximate Share of 200 Questions
Anatomy and Physiology15%About 30 items
Musculoskeletal Conditions30%About 60 items
Orthopedic History and Physical Examination15%About 30 items
Imaging and Laboratory Studies10%About 20 items
Treatment of Musculoskeletal Conditions30%About 60 items

The item counts above are simple arithmetic from the published percentages applied to 200 questions; actual forms may vary slightly. The planning takeaway is clear: Musculoskeletal Conditions and Treatment of Musculoskeletal Conditions together make up 60% of the exam. A candidate who is strong on conditions and treatment but weak on imaging can still absorb that gap more easily than a candidate who is shaky on the two 30% domains.

For a deeper walk through each area, see the full OPA-C exam domains guide.

High-Yield Content by Domain

The handbook organizes the exam by domain, and the concrete topics below are the ones a working orthopaedic PA or surgical-assistant candidate should be able to handle without hesitation. Use them as a self-check list rather than a complete syllabus.

Domain 1: Anatomy and Physiology (15%)

The foundation for everything else. Expect questions that link structure to function and to injury.

  • Bone structure, remodeling and fracture healing stages
  • Joint types, ligament and tendon attachments, and muscle innervation by region
  • Neurovascular relationships around the shoulder, elbow, wrist, hip, knee and ankle
  • Surgical approaches framed through anatomy: what structures are at risk and why

Domain 2: Musculoskeletal Conditions (30%)

The heaviest domain. Be ready to recognize the condition from a short clinical vignette and know its typical presentation, natural history and complications.

  • Fractures and dislocations across the upper and lower extremity and the spine
  • Degenerative, inflammatory, infectious and metabolic bone and joint disease
  • Sports and overuse injuries, including ligament, meniscal and tendon pathology
  • Pediatric orthopaedic conditions and growth-related considerations
  • Tumors and tumor-like lesions at a recognition level

Domain 3: Orthopedic History and Physical Examination (15%)

This domain mirrors the hands-on role. Questions test what you ask, what you examine and what a finding means.

  • Focused orthopaedic history: mechanism of injury, onset, red flags, functional limits
  • Inspection, palpation, range of motion, strength grading and neurovascular assessment
  • Joint-specific special tests and what a positive result suggests
  • Distinguishing a spinal source from a peripheral source of limb symptoms

Domain 4: Imaging and Laboratory Studies (10%)

The smallest domain, but it feeds scenario questions in Domains 2 and 5, so it pays to be fluent.

  • Choosing the right modality: plain radiographs, CT, MRI, ultrasound and nuclear studies
  • Standard radiographic views and the findings that define common fractures and arthritis
  • Laboratory markers used in suspected infection, inflammatory arthritis and metabolic bone disease

Domain 5: Treatment of Musculoskeletal Conditions (30%)

The other 30% domain. Expect decision-making items: operative versus nonoperative care, what comes next, and what to watch for.

  • Immobilization: splinting and casting principles and complication recognition
  • Operative management concepts, fixation methods and perioperative care
  • Injections, medications and pain management in an orthopaedic setting
  • Rehabilitation principles, weight-bearing progression and follow-up
  • Recognizing and responding to postoperative complications
Scenario-style thinking: Because Domains 2 and 5 are tied at 30% each, many items will chain a diagnosis to a management decision. Practice answering in two steps: first name the condition from the presentation, then pick the treatment or next step that fits it. Our OPA-C study guide shows how to build that habit into your preparation.

Eligibility Snapshot

Eligibility is not a single route. The 2026 handbook requires legal U.S. residency at the time of application and at the time of testing, plus one of three education pathways:

  1. Completion of an orthopedic physician assistant, primary-care PA, or nurse practitioner program.
  2. Completion of a master's-level orthopedic-assisting program.
  3. 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 applies to the allied-health route only, not to every pathway. A common mistake is assuming everyone needs five years of experience. All pathways do 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.

For the full qualification picture, see the OPA-C requirements guide.

2026 Windows, Deadlines and the Next Cycle

The exam is offered in published windows rather than on demand. Each window has a separate application deadline.

2026 Application DeadlineTesting Window
January 2February 7-21
May 13June 13-27
September 9October 10-24

As of October 15, 2026, the final 2026 window is already in progress and its application deadline has passed. The next published window is February 20-March 6, 2027, with an application deadline of January 20, 2027. Build your plan backward from that deadline, and remember that accommodation requests are due at least eight weeks before the testing window, which is earlier than the application deadline in practical terms. A separately published 2027 handbook exists, but this article follows the 2026 edition; check the current handbook before you register for a 2027 window. More scheduling detail is in the OPA-C exam dates guide.

Fees and Registration Mechanics

TransactionAmountNotes
Initial certification examUS$450Standard first-time fee
Recertification by examinationUS$350Includes testing-center fees and a US$75 non-refundable administrative component
Rescheduling within the same windowUS$50Permitted 29-5 days before the appointment
One-time transfer to a new testing periodUS$215A different transaction from rescheduling
Optional official practice productUS$7575 items; not the certification exam

The reschedule and transfer fees are not routine parts of the initial exam cost. They apply only if your plans change. Budget US$450 for a first attempt and treat the other amounts as contingencies. For a fuller breakdown, including how costs compare over the life of the credential, see the OPA-C certification cost guide.

Test-Day Rules That Trip People Up

  • Valid government photo ID must match your registration name.
  • You sign a confidentiality agreement and may not share exam content.
  • The exam is closed book; unauthorized references and electronic devices are prohibited during the exam and during breaks.
  • There are no scheduled breaks. If you step away, the timer keeps running.
  • Results arrive roughly four weeks after the window closes, so do not expect same-day scores.

Plan your hydration, meals and bathroom habits around a continuous 195-minute block. Practice sitting through long question sets at home so that your concentration holds in the final third of the exam, when fatigue tends to cost the most points.

Key Takeaway

Treat the clock as your scarcest resource. With 200 items in 195 minutes and no pause for breaks, aim to move briskly through straightforward recall items so you bank time for the longer clinical scenarios in Domains 2 and 5.

The Official Practice Product and Study Resources

The optional official practice product has 75 items and costs US$75. It is a useful way to experience the format, but understand its limits: it is not the 200-question certification exam, it does not provide an individual answer key, answer rationales or item-level correctness review, and its score report is not a validated predictor of how you will do on the real exam. Use it for familiarity with style, not as a pass/fail forecast.

The issuer's older Board Certification page states that no official study guide exists and that a particular commercial guide is not approved. Independent study articles, question banks and courses, including ours, are not issuer-endorsed. That does not make them useless, but you should treat them as supplementary tools and anchor your preparation to the five published domains. If you want a candid read on difficulty before committing, see how hard the OPA-C exam is. You can also try free questions on the OPA-C Exam Prep practice test site to gauge your starting point across all five domains.

Mapping Domains to Weeks

Generic study advice matters less than allocating time in proportion to the exam blueprint. Here is one way to sequence a six-week plan around the OPA-C weights, front-loading the foundation and then giving the two 30% domains the most room:

Weeks 1-2

Anatomy and Musculoskeletal Conditions

  • Anatomy comes first because it supports every later domain
  • Start the 30% conditions domain early so you can revisit it twice
  • Build a condition list by region: fractures, degenerative, infectious, sports, pediatric
Week 3

History and Physical Examination

  • Rehearse special tests and what each positive finding implies
  • Connect each exam finding back to a condition from weeks 1-2
Week 4

Imaging and Laboratory Studies

  • Learn modality choice and classic radiographic findings
  • Tie lab markers to infection, inflammatory and metabolic scenarios
Weeks 5-6

Treatment, then Full-Length Review

  • Treatment is the second 30% domain, so give it the most question practice
  • Finish with timed sets that mimic 200 questions in 195 minutes
  • Return to your weakest condition categories using your practice results

Adjust the length to your starting point. Candidates coming from a master's orthopedic-assisting program may need less anatomy review, while those on the allied-health work-experience route may need more time on structured knowledge in imaging and conditions.

After You Pass: Renewal and Practice Authority

Certification lasts four years. To renew you can either sit for the current examination again or earn 120 CME hours, of which at least 50% must be orthopaedic-related and at least 40 must be Category I. CME submission is due October 31 of the renewal year, and a late fee of US$100 applies. Do not rely on an older October 1 deadline you may see on other sites.

Processing fees for CME renewal are US$2 per credit for eligible NAOT or approved OPA-organization members and US$5 per credit for non-members. For a 120-credit submission, that works out to base totals of US$240 for members and US$600 for non-members. The listed member checkout through a TCOPA/NAOT PayPal option adds US$10, for a total of US$250. These figures come from the issuer's maintaining-certification information, so confirm them before you submit.

One important caution: certification does not itself establish state-specific practice authorization or institutional privileges. The handbook directs you to verify those requirements separately with your state and employer. Certification is a credential; it is not a license. Once you are certified, you may want to explore OPA-C jobs, what the credential means for earnings, and whether it is worth it for your situation. If you are still deciding between formal programs and on-the-job preparation, our overview of OPA-C training can help.

Frequently Asked Questions

How many questions are on the OPA-C exam and how long do I have?

The 2026 handbook lists 200 multiple-choice objective questions and three hours 15 minutes (195 minutes) of testing time. There are no scheduled breaks, and permitted breaks do not stop the timer.

Which domains carry the most weight?

Musculoskeletal Conditions and Treatment of Musculoskeletal Conditions are tied at 30% each. Anatomy and Physiology and Orthopedic History and Physical Examination are 15% each, and Imaging and Laboratory Studies is 10%.

What is the passing score?

The retrieved 2026 sources do not publish a numeric passing threshold or a current cohort pass rate. PTC reports pass/fail along with content-area and total scores about four weeks after the testing window closes.

When can I take the exam next?

As of October 15, 2026, the final 2026 window is in progress and its application deadline has passed. The next published window is February 20-March 6, 2027, with a January 20, 2027 application deadline.

Does passing the exam let me practice in my state?

No. Certification does not by itself establish state-specific practice authorization or institutional privileges. The handbook directs candidates to verify those requirements separately before relying on the credential for practice.

Keep this cheat sheet next to your calendar: the 200-question, 195-minute format, the 30/30 domain split, and the deadline and fee mechanics are the facts that most often catch candidates off guard.
