What This Cheat Sheet Covers (and What It Does Not)
OT-SC here means Orthopaedic Technologist-Surgery Certified, the surgical-specialty credential offered through the National Board for Certification of Orthopaedic Technologists, Inc. (NBCOT) at nbcot.net. It is an add-on to the Orthopaedic Technologist Certified (OTC) credential. It is not related to the occupational-therapy board that shares a similar-looking acronym online, so ignore any fee, date, or pass-rate figure that comes from that world.
This page condenses the facts you need into scannable blocks. For deeper treatment, follow the links to our OT-SC study guide and the complete domains guide. If you are brand new to the credential, start with What Is OT-SC? and come back here when you are ready to review.

Eligibility and Paperwork Checklist
The OT-SC is not open to first-time orthopaedic technologists. Before you can register, the following must be in place:
- Current OTC certification, with evidence of current status.
- At least one year of orthopaedic surgical experience.
- Notarized verification from two people: the attending musculoskeletal physician and the operating-room supervisor.
The dual-signature requirement is the step candidates most often underestimate. Notarization takes coordination, and two busy clinical leaders must both sign. Start collecting those signatures well before the registration window you are aiming for. The full breakdown lives in our OT-SC requirements guide.
Key Takeaway
Treat the notarized physician and OR-supervisor verifications as a project with its own timeline. Missing paperwork, not weak knowledge, is a common reason candidates miss a testing window.
The Four Domains and Their Weights
The weights below are the official exam objectives as printed on page 8 of the 2026 OT-SC Certification Examination Application Instruction Book (revised November 2025). They describe what is tested, not how a prep course should be organized.
| Domain | Weight |
|---|---|
| Domain 1: Pre-Operative Management | 12% |
| Domain 2: Intra-Operative Management | 52% |
| Domain 3: Post-Operative Management | 25% |
| Domain 4: Regulatory and Ethical Responsibility | 11% |
Domain 1: Pre-Operative Management (12%)
The smallest clinical domain covers everything that happens before the incision, from the technologist's role in preparing the case to confirming that the right people, equipment, and information are ready.
- Room, equipment, and instrument readiness for orthopaedic procedures
- Patient and procedure verification steps
- Coordination with the surgical team before the case begins
Domain 2: Intra-Operative Management (52%)
This is the heart of the exam. Expect questions on what a surgical orthopaedic technologist actually does at and around the operating table.
- Assisting with positioning, exposure, and procedure-specific equipment
- Implant and instrument handling during orthopaedic cases
- Maintaining sterile technique and situational awareness during the procedure
- Responding appropriately when a case does not go as planned
Domain 3: Post-Operative Management (25%)
At 25%, the post-operative domain is nearly as heavy as the other two minor domains combined. Do not treat it as an afterthought.
- Immediate post-procedure responsibilities and handoffs
- Dressings, immobilization, and postoperative device application
- Patient instructions and recognizing complications that need escalation
Domain 4: Regulatory and Ethical Responsibility (11%)
The smallest domain, but also the most predictable to study because it is rule-based.
- Scope-of-practice boundaries for the surgical orthopaedic technologist
- Patient rights, confidentiality, and professional conduct
- Documentation and regulatory expectations in the operating environment
Why Intra-Operative Management Deserves Half Your Time
With 52% of the exam, Domain 2 is the single biggest lever on your score. Because the cut score is 108 of 150, you can lose a fair number of questions overall, but a weak showing in the largest domain is very hard to offset elsewhere. A candidate who is strong in Domains 1, 3, and 4 yet shaky in the operating room content is statistically exposed.
The exam is built for people who already hold OTC and have worked in surgery for at least a year, so questions lean toward applied judgment rather than rote definitions. Think "what is the technologist's appropriate action in this scenario" rather than "define this term." The difficulty guide discusses what that means for how you prepare.
Fees and Registration Mechanics
| Charge | Amount |
|---|---|
| Examination fee | USD 450 |
| New-applicant application fee (nonrefundable) | USD 100 |
| Base total | USD 550 |
| Late registration fee, when applicable | USD 100 |
| Credit-card surcharge, when applicable | 3% |
A few mechanics trip people up:
- Credit cards are not accepted for the application fee. Plan an alternative payment method for that portion.
- Application-fee exemptions exist, but none is an examination-fee waiver. The handbook exempts current holders recertifying by exam without a lapse, and retests within six months of the initial application, from the application charge. The general examination page also grants an application-fee waiver to active-duty U.S. military for OT-SC.
- Rescheduling and cancellation charges are separate. The handbook's overlapping five-day rescheduling and no-show language is not a guarantee of a close-in rescheduling option, so confirm your specific situation before assuming you can move your date.
For a fuller pricing walk-through, including what to budget around the exam itself, see the OT-SC certification cost breakdown. If you are weighing whether the spend is justified, our ROI analysis and salary guide discuss it, though no credential-specific pay premium is guaranteed.
Test-Day Rules
- Bring physical government-issued photo ID. Digital copies on a phone are not substitutes.
- Bring printed admission documentation. Again, digital substitutes are not accepted.
- Expect a closed-book environment. No testing aids, no scratch paper, no writing instruments. Any reasoning has to happen in your head or on whatever the test center provides under its own rules.
- Remember that approved breaks use exam time. The three-hour clock does not stop for them.
- Know your window. Regular windows are February, April, June, September, and November. Check the exam dates and deadlines article before choosing.
Scoring and Retake Rules
- Cut score: 108 correct on the 150-question form, set through the Angoff standard-setting method.
- No same-month retest. You cannot sit twice in the same calendar month.
- After three consecutive failures, you must wait six calendar months from your last attempt.
- Retests within six months of the initial application are exempt from the application charge, but not from the examination fee.
On pass rates: the Report to the Profession 2025 records 14 passes among 15 OT-SC candidates, which the issuer rounds to 93%. That is a very small historical cohort, so treat it as a snapshot rather than a forecast for 2026. Our pass rate article explains how to read a number like that responsibly.
Renewal Math: OTC and OT-SC Together
OT-SC is not a stand-alone credential. You must maintain your OTC continuously, and your OT-SC rides on top of it.
| Renewal Element | Rule |
|---|---|
| Initial OT-SC expiration | Aligns with your existing OTC expiration, not automatically six years from the OT-SC exam date |
| Later cycles | Six years |
| Total CEUs, combined OTC/OT-SC | 120 approved CEUs (not 120 per credential) |
| Full-cycle Category 1 | At least 20 |
| Full-cycle Category 1A (surgical) | At least 20 |
| Remaining credits | 80, in approved categories |
| Initial Category 1A, prorated | 3, 6, 9, 12, 15, or 20 credits for one through six years remaining |
| Submission deadline | October 1 of the expiration year to avoid the USD 100 late fee |
Key Takeaway
Reexamination is an alternative to CEUs, but passing OT-SC alone does not automatically renew your OTC. Plan the renewal of both credentials together, and check the current CEU guidelines before each cycle.
Sequencing Your Review by Domain
This is an editorial suggestion, not an official curriculum. The idea is simple: weight your calendar by exam weight, and place the most paperwork-like content where it fits your energy. Adjust the length to your own timeline; the full study guide offers more detail.
Domain 4 and Domain 1
- Learn scope-of-practice and ethics rules while your mind is fresh; they are rule-based and quick to lock in
- Review pre-operative readiness workflows so the front end of every case scenario feels automatic
Domain 2: Intra-Operative Management
- Give the 52% domain the longest block of calendar time
- Cover procedures outside your daily practice so no subspecialty is unfamiliar
- Work scenario questions that ask for the technologist's appropriate action
Domain 3: Post-Operative Management
- Review immobilization, handoffs, and escalation of complications
- Run timed mixed sets at roughly 72 seconds per question
When you start timed work, our OT-SC practice tests let you rehearse the 150-question pace and see which domains need another pass.
Document Quirks Worth Knowing
NBCOT's public materials are not perfectly uniform, and a careful candidate should know where the seams are:
- Two sets of domain numbers. The undated Role Delination / Examination Breakdown sheet lists item counts of 17, 78, 38, and 17 alongside 12%, 52%, 25%, and 11%. The counts do not all equal the exact percentage shares. Rely on the handbook's official weights and do not try to calculate replacements.
- Year labels. The landing-page introduction still labels some links for 2024, but the linked handbook and application are the 2026 versions, revised November 2025.
- Undated supporting documents. The scoring explanation and the role breakdown are undated, so treat the handbook as the controlling source and confirm anything time-sensitive on the issuer's pages.
- No commercial endorsement. NBCOT does not endorse commercial preparation products, including ours. Use any prep resource as a supplement to the official handbook, not a replacement for it.

Frequently Asked Questions
The exam has 150 four-option multiple-choice questions and allows 3 hours of examination time, not counting the tutorial. Approved breaks use examination time.
The published passing cut score is 108 on a 150-question form, set using the Angoff standard-setting method. It is not the scaled-700 system used by the OTC exam.
The base cost is USD 550: a USD 450 examination fee plus a USD 100 nonrefundable new-applicant application fee. A USD 100 late registration fee and a 3% credit-card surcharge can apply, and credit cards are not accepted for the application fee.
Intra-Operative Management, at 52% of the exam. Pre-Operative Management is 12%, Post-Operative Management is 25%, and Regulatory and Ethical Responsibility is 11%.
No. OT-SC is not stand-alone, and passing it alone does not automatically renew OTC. Combined renewal by CEUs requires 120 total approved credits, submitted by October 1 of the expiration year to avoid a USD 100 late fee.
Keep this sheet beside the official 2026 handbook, verify any date or fee against NBCOT before you register, and build your calendar around the 52% operating-room domain. For a broader orientation, see What Is OT-SC Certification? and the OT-SC Exam Prep home page.
