ONC Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why There Is No Fixed 2026 Calendar for the ONC

Candidates searching for "ONC exam dates 2026" often expect a list like the one nursing specialties publish for paper-and-pencil sittings: three or four national dates, a registration deadline for each, and a results release day. The Orthopaedic Nurse - Certified (ONC) credential, issued by the Orthopaedic Nurses Certification Board (ONCB), does not work that way in the materials this article draws on. Applications run through ONCB's LearningBuilder system, and testing is delivered by Meazure Learning either at a computer center or through live remote proctoring. The handbook describes delivery in the U.S., Puerto Rico, and Canada.

In practice, this means your "exam date" is the appointment you choose after your application is approved, constrained by the eligibility and scheduling rules that ONCB sets, not by a national calendar. This article walks through those rules so you can plan around them instead of waiting for a date list that may never come. If you are still deciding whether this credential is right for you, start with our overview of what ONC certification is, then return here for the mechanics.

The Three Clocks: Eligibility, Booking, and Retesting

The single most common planning mistake is treating every ONC time limit as one interchangeable "window." The handbook actually defines several separate clocks, and they start and stop for different reasons.

Notice that "90 days" appears twice with two different meanings. One is a minimum waiting period between a failed exam and your next one. The other belongs to a set of completion, scheduling, and refund provisions in the handbook. Do not collapse them, and do not collapse either of them into the 366-day eligibility period. If a forum post tells you "you have 90 days to test," ask which rule it means and check the handbook language yourself.

From Application to Appointment: The Registration Sequence

The order of operations matters because earlier steps start clocks that later steps depend on. A sensible sequence looks like this:

1. Confirm eligibility first. You need current unrestricted RN licensure (or the board's specified foreign first-level nurse/equivalency route), two full years of RN experience, and at least 1,000 orthopaedic RN practice hours in the previous three years. A BSN is not required. The full walkthrough is in our ONC requirements guide.
2. Line up your supervisor. Verification from your immediate supervisor must be signed within 180 days of your application. If your supervisor is slow, travels often, or is changing roles, address that before you start the application so the signature does not age out.
3. Decide on membership. Fees differ for eligible full NAON, AANP, NOVA, or CONA members versus non-members, and student or associate memberships do not qualify. Membership must remain active through the examination.
4. Submit through ONCB LearningBuilder. This is the application portal, and it is where your eligibility is established.
5. Schedule with Meazure Learning. Once approved, you choose a computer center or live remote proctoring and pick your appointment.

The reason to front-load steps 1 through 3 is simple: your 180-day verification clock and your 366-day application eligibility both begin ticking once you apply. Applying months before you are mentally ready to test wastes runway you may need later.

Test Center vs. Live Remote Proctoring

Choosing a delivery mode is part of choosing a date, because the two formats have different availability patterns and different logistics.

Neither mode changes the content. The exam is 150 multiple-choice questions, of which 135 are scored and 15 are unscored pretest items, with three hours of examination time. Breaks are allowed but happen within the exam clock, so they consume testing time rather than pausing it.

Fee Mechanics That Affect When You Book

Money and timing interact more than most candidates expect. The current initial fee is US$325 for eligible full NAON, AANP, NOVA, or CONA members and US$450 for non-members. Ordinary retake fees are US$275 for members and US$400 for non-members. Because membership must remain active through your examination, a membership that lapses before your appointment could change the fee situation you planned around.

This creates two practical timing questions:

• Is your membership renewal date before or after your target exam date? If renewal falls in between, renew first or move your appointment.
• Would joining a qualifying organization before applying lower your total cost? The gap between member and non-member pricing is significant enough to run the numbers. Our ONC certification cost breakdown lays out the full picture, and the ROI analysis helps you weigh the spend against career value.

Test-Day Rules Worth Knowing Before You Pick a Date

A date is only useful if you can actually sit the exam on it. These rules can quietly derail an appointment:

• ID match. Bring valid government photo ID that matches the name on your registration. A mismatch between your nursing license name and your ID name should be resolved before you schedule, not on exam morning.
• Closed book. No unauthorized reference materials and no calculators.
• Three hours, breaks included. Plan for sustained concentration. With 150 items in 180 minutes, you have roughly a minute and a half per question on average, so pacing practice matters.
• Scheduling around your shifts. Do not book the day after a night rotation. Choose a time of day when you are typically sharpest.

For a sense of how demanding the exam is once you are in the chair, see our ONC difficulty guide, and for the scoring threshold, our ONC passing score breakdown. The current Exam Description publishes a raw passing threshold of 97 out of 135 scored items, though standard setting and equating can permit slight form-specific differences.

Choosing a Date: Building the Plan Backward from the Exam

Once you understand the clocks, the smartest approach is to pick your target appointment first and work backward. This is the one place where a study schedule belongs in a scheduling article, and it should be driven by the ONC's actual structure rather than a generic template.

The exam's content outline has two intersecting axes. The eight condition categories carry fixed item counts (Degenerative Disorders 51, Orthopedic Trauma 26, Sports Injuries 15, Inflammatory Disorders 11, Metabolic Bone Disorders 12, Congenital/Pediatric Disorders 7, Musculoskeletal Tumors 7, Neuromuscular Disorders 6, totaling 135). The six cross-cutting nursing tasks carry ranges (Self Care 22-32, Pain 35-45, Complications 31-41, Activity 15-25, Nutrition 3-9, Psychosocial 3-9). These axes intersect and must not be added together; every scored question is classified on both. Our domains guide explains the mapping in depth.

An eight-week arc is an illustration, not a requirement. The point is that your appointment date determines how much of the runway you have, and the content weighting tells you where to spend it. For the full preparation strategy, read our ONC study guide, and when you are ready to rehearse under realistic conditions, take a timed set on the ONC practice test site.

Operative orthopaedics does not appear as a standalone domain; it is woven through relevant conditions. A candidate who studies joint replacement under Degenerative Disorders and fracture fixation under Orthopedic Trauma is already covering surgical content where the exam tests it.

After Exam Day: Retests and the June 30 Expiration Rule

Planning your first date also means knowing what happens next in either direction.

If you do not pass

Ordinary failed-attempt retesting requires at least 90 days between examinations, so your next possible date is bounded by that interval. Retake fees are US$275 for eligible members and US$400 for non-members. ONCB also has a separate Retest for Success program with its own terms; do not assume its rules match ordinary retake rules. For perspective on how candidates have fared historically, see our pass rate analysis. The most recent figure ONCB reports in its statistics summary is 58% for 2020 (316 passes among 544 examinees), which is neither a 2026 figure nor a verified first-attempt-only rate.

If you pass

Certification runs on a five-year term governed by ONCB's June 30 expiration rule. That means your renewal planning should begin early, because the expiration date is tied to that rule rather than to your personal anniversary. Renewal by continuing education requires unrestricted RN licensure, 1,000 orthopaedic practice hours in the previous five years, and 75 contact hours, including at least 50 clinical orthopaedic hours and no more than 25 general nursing hours. The CE renewal fee is US$275 for eligible members and US$400 for non-members. Passing the reexamination before expiry is an alternative route. Older materials citing 100 hours or a 70+30 split are outdated; current 75-hour rules supersede them.

Passing also opens the door to the career benefits that motivated you in the first place. See our guides on ONC salary and ONC jobs for what that can look like in practice.
