- Frequently Asked Questions
- The published OT-SC passing cut score is 108 correct on a 150-question form, set by NBCOT using Angoff standard setting.
- OT-SC is not scored on the OTC scaled-700 system; do not apply scaled-score logic from OTC prep.
- Intra-Operative Management carries 52% of the exam, so it dominates how you reach 108.
- The exam is four-option multiple choice, three hours, closed-book, with approved breaks consuming exam time.
The Number: 108 Out of 150
If you are searching for the OT-SC passing score, the answer is short: the National Board for Certification of Orthopaedic Technologists (NBCOT) publishes a passing cut score of 108 on a 150-question examination form. That is the figure stated on the issuer's current OT-SC examination page and in its linked explanation of how the passing score is determined.
Put plainly, 108 of 150 is 72% of the items on the form. That percentage is simply arithmetic on the published cut score, so treat it as a planning aid rather than a separately published threshold. The number that matters is 108 correct answers.
Two practical points follow from a raw cut score of 108:
- There is no partial-credit mindset to adopt. Each question is multiple choice with four options, so every item is either right or wrong. Leave nothing blank in your practice and in the live exam.
- You can miss up to 42 items and still land at the cut. That margin is the useful way to think about the number: it tells you how much uncertainty you can absorb, not how perfect you must be.
How the Cut Score Is Set: Angoff Standard Setting
The OT-SC cut score is not a curve and not a fixed percentage chosen out of convenience. NBCOT's published scoring explanation describes an Angoff standard-setting approach. In general terms, Angoff-style methods ask a panel of qualified subject-matter experts to judge, item by item, how a minimally competent candidate would perform. Those judgments are combined into a recommended cut score for the form.
What this means for you as a candidate:
- The standard is about competence, not competition. You are not ranked against the other people sitting the exam that month. Your result depends on reaching the cut score, not on beating a cohort.
- The bar reflects practice-relevant judgment. Because the panel evaluates items against what a minimally competent surgical orthopaedic technologist should know, questions tend to reward applied operating-room judgment over trivia.
- The explanation document is undated. NBCOT's linked scoring explanation carries no revision date, so confirm the current cut score on the official OT-SC examination page before test day rather than relying on any third-party summary, including this one.

Why the OTC Scaled-700 System Does Not Apply
Many OT-SC candidates arrive having already passed the OTC (Orthopaedic Technologist Certified) examination, which is reported on a scaled-score system with a 700 threshold and a 165-item form. It is natural to assume OT-SC works the same way. It does not.
| Feature | OT-SC (this article) | OTC (do not transfer) |
|---|---|---|
| Passing standard | Cut score of 108 | Scaled score of 700 |
| Form length | 150 questions | 165 items total |
| Standard setting | Angoff, per NBCOT scoring explanation | Separate OTC scoring materials |
| Prerequisite relationship | Requires current OTC | Foundational credential |
The practical consequence: do not convert OT-SC practice results into a "scaled 700" estimate, and do not import OTC score-report habits. Track raw correct answers against 108. If you are still confirming that you qualify to sit the exam at all, start with OT-SC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Exam Form You Are Scoring Against
Knowing the shape of the exam helps you convert 108 into a pacing plan.
- Length: 150 four-option multiple-choice questions, in American English.
- Time: 3 hours of examination time, excluding the tutorial. That works out to roughly 72 seconds per question if you never pause.
- Breaks: Approved breaks use examination time. The clock does not stop for you, so a break is a trade of minutes for composure.
- Delivery: Testing runs through SMT/Prometric with IsoQuality Testing (IQT) at U.S. testing centers.
- Closed-book: No testing aids, no scratch paper, no writing instruments. Anything you need to work out must be worked out in your head.
- Check-in: Bring a physical government-issued photo ID and your printed admission documentation. Digital substitutes are not accepted.
Where the Points Live: Domain Weights
A cut score of 108 only becomes useful when you know where the 150 questions come from. The four domains below use the names and percentages printed in the 2026 OT-SC Certification Examination Application Instruction Book (revised November 2025). They are official weighted exam objectives, not study-curriculum headings.
| Domain | Official 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 2: Intra-Operative Management (52%)
More than half the exam. This is where passing is won or lost, because no other domain can compensate for weakness here.
- Operating-room workflow from the technologist's role during orthopaedic procedures
- Instrumentation, implants and equipment as they are used during surgery
- Patient positioning, sterile technique and intra-operative safety judgment
- Anticipating the surgeon's needs and responding to changes during a case
Domain 3: Post-Operative Management (25%)
The second-largest block and the one candidates often under-study after drilling the operating room.
- Immediate post-procedure responsibilities and handoffs
- Dressings, immobilization and application of post-operative devices
- Recognizing and reporting post-operative concerns within scope of practice
Domain 1: Pre-Operative Management (12%)
A smaller domain, but its questions often reward systematic preparation habits.
- Case and room preparation, supplies and verification steps
- Patient and procedure readiness checks
Domain 4: Regulatory and Ethical Responsibility (11%)
The smallest block, but a reliable place to bank points because the content is rule-based.
- Professional conduct, scope of practice and patient rights
- Regulatory and safety responsibilities in the surgical environment

Reading the 93% Figure Without Over-Reading It
NBCOT's Report to the Profession 2025 records 14 passes among 15 OT-SC candidates, which the issuer rounds to 93%. That is a real, published figure, and it is encouraging, but it needs context before it shapes your expectations.
- The cohort is tiny. Fifteen candidates is a small group. One additional failure would have moved the rounded percentage noticeably.
- It is historical. It describes candidates tested in the reporting period, not the 2026 testing windows.
- The candidates are pre-screened. Everyone sitting OT-SC already holds OTC and has at least a year of orthopaedic surgical experience, so this is a self-selected, experienced group.
The right conclusion is modest: experienced, prepared candidates have done well on this exam, but the sample is too small to promise you a result. For more on interpreting the data, see OT-SC Pass Rate 2026: What the Data Shows.
Planning Around 108: A Domain-by-Domain Schedule
This is an editorial suggestion, not an NBCOT requirement. The only reason to include a schedule here is that the 52% weight of Intra-Operative Management should dictate the order of your preparation. Adjust the timing to your own calendar and to the testing window you choose.
Intra-Operative Management, first pass
- Review procedure-by-procedure setups from your own case experience
- Write down your weakest procedures and instrument families
- Take a short diagnostic set and record raw correct answers
Post-Operative Management
- Work through dressings, immobilization and post-procedure responsibilities
- Practice judgment questions about what to report and to whom
Pre-Operative Management and Regulatory and Ethical Responsibility
- Cover the smaller domains in one concentrated block
- Bank the rule-based points that depend on recall rather than case experience
Mixed timed sets against the 108 target
- Run full-length 150-question timed sets with no notes or scratch paper
- Return to Intra-Operative Management for any item you missed twice
For a fuller preparation framework, see OT-SC Study Guide 2026: How to Pass on Your First Attempt, and test your readiness with timed sets on the OT-SC Exam Prep practice test site.
Key Takeaway
Track raw correct answers against 108, and treat any practice set where Intra-Operative Management falls short as a failing set, no matter how well you do elsewhere. With 52% of the exam in that single domain, you cannot reach the cut score by excelling in the three smaller ones.
What a Miss Costs: Fees, Windows and Retake Rules
The passing score is tied to real money and real calendar constraints, which is why it is worth understanding what a missed attempt does to your timeline.
| Item | Detail |
|---|---|
| Examination fee | USD 450 |
| New-applicant application fee | USD 100, nonrefundable |
| Combined baseline | USD 550 before extras |
| Late registration | USD 100 additional when applicable |
| Credit-card surcharge | 3% when applicable; credit cards are not accepted for the application fee |
Some candidates are exempt from the application charge, and none of these exemptions waives the examination fee itself:
- Current OT-SC holders recertifying by exam without a lapse
- Retests within six months of the initial application
- Active-duty U.S. military candidates, per the current general examination page
Rescheduling and cancellation charges are separate, and the handbook's overlapping five-day rescheduling and no-show language means you should confirm your specific situation with NBCOT instead of assuming a close-in change is available.
Windows and retake limits
- Regular testing windows: February, April, June, September and November. Active-duty military candidates may test throughout the year.
- No same-month retest. A failed attempt pushes you to a later window.
- After three consecutive failures, you must wait six calendar months from your last attempt.
Planning your attempt around these windows is covered in OT-SC Exam Dates 2026: Testing Windows, Deadlines & Scheduling, and the full cost picture is in OT-SC Certification Cost 2026: Complete Pricing Breakdown.
After You Pass: Score Meets Credential Maintenance
Reaching 108 earns the credential, but OT-SC is not a stand-alone certification. You must maintain your OTC continuously, and your OT-SC standing travels with it.
- Initial expiration aligns with your existing OTC expiration, not automatically six years from the OT-SC exam date. Later cycles run six years.
- Combined CEU renewal requires 120 total approved CEUs, not 120 per credential. For a full cycle, that includes at least 20 Category 1 and 20 Category 1A surgical credits, with the remaining 80 in approved categories.
- Prorated Category 1A requirement: for the initial cycle, the Category 1A requirement is prorated to 3, 6, 9, 12, 15 or 20 credits for one through six years remaining, respectively.
- Deadline: submit renewal CEUs by October 1 of the expiration year to avoid the USD 100 late fee.
- Reexamination is an alternative to CEUs, but passing OT-SC alone does not automatically renew OTC.
Whether the effort pays off for you depends on your workplace and goals. See Is the OT-SC Certification Worth It? Complete ROI Analysis 2026 for a balanced view, and note that no credential-specific pay premium should be assumed.
Frequently Asked Questions
NBCOT publishes a passing cut score of 108 on a 150-question form. This is stated on the issuer's current OT-SC examination page and in its linked explanation of how the passing score is determined.
No. The OT-SC uses a cut score of 108 on a 150-question form, with Angoff standard setting. The OTC's scaled-700 system and 165-item total do not apply to this exam.
You have 3 hours of examination time for 150 questions, excluding the tutorial, which works out to about 72 seconds per question. Approved breaks use examination time rather than pausing the clock.
Not necessarily. The figure reflects 14 passes among 15 candidates in the 2025 report, a very small and pre-screened group. It is a historical data point, not a forecast for 2026.
You must wait for a later testing window, because same-month retests are not allowed. Retests within six months of your initial application are exempt from the application charge, though the examination fee still applies. After three consecutive failures, a six-calendar-month wait from your last attempt applies.
The OT-SC passing score is a single, concrete target: 108 correct out of 150. Because more than half the exam sits in Intra-Operative Management, your preparation should be built around that domain first. To confirm every detail before you register, consult the official NBCOT OT-SC examination page and the 2026 candidate handbook, and keep the OT-SC Cheat Sheet 2026 handy for a quick review of must-know facts.
