The ONP-C examination is based on an analysis of the practice of orthopaedic nurse practitioners. From that analysis, test specifications (test blueprint or content outline) are constructed to identity the percentage of questions that will cover each area of practice (musculoskeletal health condition) and each advanced practice nursing role.
The ONP-C examination contains 150 questions. Of these, 135 are scored; the remaining 15 questions are pilot items, and the candidate’s performance on those questions will not be reflected in the exam score. A raw score (number of questions answered correctly) of 96 is needed to pass the examination.
Individual candidate examination results are maintained within the secure data base hosted by Meazure Learning, ONCB’s test vendor. They are reported securely to the ONCB so certification documents can be provided to new credential holders. ONCB does not report this information to outside agencies or individuals, and only uses pass-fail distinctions for future examination marketing.
Successful ONP-C exam candidates earn certification for a five-year term.
