ExploreAbout this exam
The ONC® (Orthopaedic Nurse Certified) credential is awarded by the Orthopaedic Nurses Certification Board (ONCB), an independent certification body. ONCB describes the ONC certification program as one that "advances the care of the orthopaedic patient and promotes excellence in specialty nursing practice," and states that the exam was "written for nurses by nurses based on analysis of real orthopaedic nurses' practice." The credential is intended for nurses practicing in orthopaedic settings who want to demonstrate specialty knowledge; ONCB notes the ONC credential is recognized by colleagues and employers as a mark of excellence and shows the certificant is "educated, engaged, and committed to providing the highest quality care to your patients." This page does not restate the exam's content outline - candidates should consult ONCB's own Exam Description page for the current blueprint, since ONCB does not publish the detailed domain breakdown on its landing page. Preparation follows the path ONCB lays out: confirm eligibility on the Exam Eligibility page, review fees, register for the exam, then use the Exam Study Resources and ONCB's online exam prep products. ONCB also publishes an Exam Candidate Handbook covering the full exam process, a free Category A CE list (BONEafide) useful for recertification, and scholarship opportunities for exam costs. This page is an independent study resource and is not affiliated with or endorsed by ONCB; always confirm current requirements directly with ONCB before registering.
What you'll study
About ONC preparation
Who administers the ONC certification?
The Orthopaedic Nurses Certification Board (ONCB), based in Chicago, Illinois. ONCB also offers ONP-C and ONC-A credentials and handles first-time certification, recertification, verification, and reactivation. Contact ONCB directly at [email protected] or 1-888-561-6622 for authoritative answers about your application.
Where do I find the official exam content outline?
ONCB publishes an Exam Description page linked from the ONC Certification page. That page is the authoritative source for the current blueprint and domain weighting. This study page intentionally does not restate a content outline, because ONCB revises its exam and only ONCB's own materials reflect the version you will actually sit.
How do I check whether I am eligible to sit the exam?
ONCB maintains a dedicated Exam Eligibility page linked from the ONC Certification page. Eligibility criteria are set by ONCB and can change, so read that page rather than relying on secondhand summaries. If your situation is unusual, email ONCB before paying any fee.
What does the exam cost, and how long is it?
ONCB lists fees on its own Exam Fees page and describes the exam process in the Exam Candidate Handbook. Neither the item count nor the time limit is stated on the ONC Certification landing page, so confirm both in the Handbook before you plan your pacing strategy.
What happens if I fail?
ONCB addresses this directly through its "Did you fail the test?" page and a separate Retest for Success™ program. Read both before rescheduling. Candidates who fail typically benefit from reviewing which content areas pulled their score down, then rebuilding study time around those areas rather than repeating the same broad review.
Is there financial help for the exam fee?
Yes. ONCB maintains a Scholarships and Awards page linked from the ONC Certification page. If cost is a barrier, check scholarship options before registering, since award timing may affect when you can schedule. Employers sometimes reimburse certification fees as well, so ask your nurse educator.
What study materials does ONCB itself offer?
ONCB sells ONC Online Exam Prep Products through its shop and maintains an Exam Study Resources page. It also publishes a BONEafide free Category A CE list, which is aimed primarily at recertification but is useful general orthopaedic learning. Third-party question banks are not endorsed by ONCB.
How do I order my study time?
Start with the official Exam Description to see what is tested, then work through orthopaedic content by body system and patient population, finishing with timed practice that mimics exam conditions. Track weak areas as you go. Broad reading without practice applying judgment to clinical scenarios is the most common way candidates underprepare.
Why do candidates typically fall short?
Usually not from lack of orthopaedic knowledge but from shallow coverage: skimming many topics once, skipping assessment and complication recognition, and never practicing under time pressure. Scenario questions reward clinical judgment, so practice justifying why one action comes before another, not just recalling facts.
How do I verify my credential once certified?
Use ONCB's online Verify Certification registry. Employers can confirm your status there. If your certification lapses, ONCB offers a credential reactivation application for expired certifications, and it also documents retired and inactive certification designations for nurses who step away from practice.
