What is the CNOR Exam?

The CNOR exam is the certification exam necessary to become a Certified Nurse Operating Room (CNOR) nurse.

​

A Certified Nurse Operating Room (CNOR) nurse is a registered nurse (RN) who specializes in perioperative nursing, assisting surgeons and other operating room (OR) staff during surgical procedures. CNOR nurses help prepare the OR, ensure that all equipment is sterile and functioning, monitor patients during surgery, and provide post-surgical care.

​

To become a CNOR, you need to demonstrate expertise in perioperative nursing and a thorough understanding of surgical procedures and patient care standards in the operating room. The CNOR exam, administered by the Competency and Credentialing Institute (CCI), evaluates knowledge of the skills and practices specific to OR nursing. Once you pass the exam, you are recognized as a CNOR-certified nurse, confirming your expertise and commitment to excellence in surgical nursing care.

CNOR Exam Outline

The CNOR exam is a written, computer-based test designed for perioperative nurses who are seeking CNOR certification, which confirms their expertise in the operating room setting. This certification exam consists of multiple-choice questions covering essential areas like patient care, surgical techniques, and OR protocols, all relevant to providing high-quality care during surgery.

​

The exam contains a total of 200 multiple-choice questions, of which 185 are scored, and the remaining 15 are unscored pretest questions. These unscored questions are included to help test new content for future exams, but they do not impact the candidate’s overall score. Because the scored and unscored questions are randomly mixed, candidates won’t know which questions count toward their final score, making it essential to give equal attention to each question.

​

Candidates have a time limit of 3 hours and 45 minutes to complete the CNOR exam, which requires careful pacing and time management. This duration is intended to give candidates ample time to carefully consider each question while demonstrating their proficiency in perioperative nursing, validating their commitment to excellence in the field. Passing the CNOR exam demonstrates the candidate’s readiness and expertise to provide specialized care in the operating room setting.

What is the format and structure of the CNOR exam?

The CNOR exam is a computer-based, multiple-choice test designed to evaluate a candidate’s competence in perioperative nursing. Knowing the format and structure of the exam can help candidates better prepare for the testing experience.

Computer-Based, Proctored Exam: The CNOR exam is administered at authorized testing centers, or it may be taken remotely if that option is available. In both cases, the test is proctored to ensure a secure testing environment.

Number of Questions: The exam consists of a total of 200 multiple-choice questions. Among these:

Scored Questions: 185 questions are scored and will contribute to the final score.
Unscored Questions: 15 questions are unscored pretest questions included to evaluate the potential use of these questions in future exams. These unscored questions are indistinguishable from the scored questions, so it’s essential to treat each question carefully.
Time Allotted: Candidates have a total of 3 hours and 45 minutes to complete the exam. This requires effective time management to ensure that all questions are addressed within the allotted time.

Question Types: All questions are multiple-choice, meaning each question will present several answer choices, with only one correct answer. The questions cover seven key content areas in perioperative nursing, such as patient assessment, intraoperative activities, infection control, and emergency situations.

 

Knowing this structure allows candidates to better anticipate the test-taking experience and pace themselves accordingly.

What is the passing score, and how is the exam scored?

Understanding the scoring system is essential for setting realistic expectations about passing the CNOR exam.

Scaled Scoring System: The CNOR exam is scored using a scaled scoring system, where scores range from 200 to 800. The passing score is 620, which reflects a candidate’s proficiency in perioperative nursing rather than the number of correct answers alone. This scaled system accounts for the difficulty of each question, creating a fair scoring system across different exam versions.

Score Composition: Only the 185 scored questions contribute to the final score. The 15 unscored questions are experimental and do not impact a candidate’s performance or final score. Since scored and unscored questions are randomly mixed, it’s essential to treat each question as if it counts toward the final result.

Pass/Fail Result: Candidates receive a pass/fail result rather than a numerical score upon completion. Those who pass the exam receive CNOR certification, while those who do not meet the passing score are informed of areas needing improvement.

 

Understanding the scoring system can help candidates feel confident about their results and prepare efficiently for a possible retake, if necessary.
 

What is the best way to manage time during the exam?

Time management is a critical skill for successfully completing the CNOR exam, as candidates have 3 hours and 45 minutes to answer 200 questions. Here are some strategies to manage time effectively:

Pacing: Given the total time, candidates have roughly 1 minute and 7 seconds per question. To stay on track, aim to complete:

  • The first 50 questions within the first hour.

  • The next 50 questions by the second hour.

Keep the final hour and 45 minutes for the remaining questions and any review.


Mark and Review: If a question proves challenging, mark it for review and move on to the next. This approach allows candidates to answer easier questions first and return to the marked questions if time allows.

Use of Breaks: Some testing formats allow candidates to take brief breaks. If possible, consider taking short mental breaks to reduce fatigue and maintain focus.

Practice with Timed Exams: Practicing with timed exams is one of the most effective ways to improve pacing. Mock exams familiarize candidates with the rhythm of a timed test and reduce anxiety related to time constraints.
 

What are the prerequisites and eligibility criteria for taking the CNOR exam?

The CNOR exam has specific eligibility requirements to ensure that candidates have adequate perioperative nursing experience and knowledge.

Current RN License: Candidates must hold an active, unrestricted RN (Registered Nurse) license in the state or country where they practice.

Professional Experience: Candidates must have a minimum of 2 years of professional experience in perioperative nursing. Additionally:

They must have completed at least 2,400 hours of perioperative nursing experience, with a minimum of 1,200 hours spent in intraoperative (surgical) settings.


These requirements are designed to ensure that candidates possess the hands-on experience and theoretical knowledge needed to perform effectively in the operating room. Meeting these criteria confirms that a candidate has the foundational experience and expertise needed to pursue CNOR certification.

What happens if I don’t pass the exam? Can I retake it?

Candidates may have concerns about retaking the exam if they do not pass on their first attempt. Fortunately, the CNOR exam allows retakes, though there are some guidelines to consider:

Waiting Period: If a candidate does not pass, they must wait 30 days before scheduling a retake. This waiting period allows candidates to study and improve in areas that need more preparation.

Retake Limits: Candidates can take the CNOR exam up to four times within a year. This provides ample opportunities for those who may need additional attempts to pass.

Retake Fees: Each attempt requires a new application and payment of exam fees. Candidates should be aware of this cost in case multiple attempts are needed.

Feedback on Performance: After a failed attempt, candidates receive feedback on their performance, highlighting the content areas that need improvement. This feedback can be invaluable for focusing on areas of weakness and adjusting study plans for subsequent attempts.

What are the benefits of CNOR certification, and how will it impact my career?

CNOR certification offers several professional advantages, enhancing a perioperative nurse’s qualifications and career prospects:

Increased Credibility: CNOR certification is a recognized symbol of expertise and commitment to perioperative nursing. It reflects a nurse’s proficiency in surgical nursing standards and their dedication to providing quality patient care.

Career Advancement: Many hospitals and healthcare facilities prefer or require CNOR certification for advanced perioperative roles, such as OR team leaders or educators. Certification can open doors to these opportunities.

Higher Earning Potential: CNOR-certified nurses may be eligible for higher salaries or bonuses. Certification validates specialized knowledge and experience, which can be valuable to employers and reflected in compensation.

Professional Satisfaction and Confidence: For many, achieving certification is a source of pride and professional satisfaction. It confirms a nurse’s dedication to their specialty and reinforces their role as a knowledgeable, reliable member of the perioperative team.

What should I bring on exam day, and what are the testing policies?

Preparation for exam day is essential to ensure a smooth testing experience. Candidates should familiarize themselves with required items, testing policies, and prohibited items.

Identification: Candidates must bring a government-issued photo ID that matches the name on their exam registration. This could be a driver’s license, passport, or other approved form of identification.

Test Center Policies: Most test centers have specific policies on:

Personal Items: Candidates are generally not allowed to bring personal items into the testing area, including phones, bags, watches, and food.
Breaks: Depending on the test format, candidates may have limited or no breaks during the exam. Those who leave the testing area for a break may have to follow specific procedures for re-entry.
Noise-Canceling Headphones and Earplugs: Test centers typically provide noise-canceling options to reduce distractions. Check in advance if these will be available.

  • Answer the Easier Questions First: If you come across a question that’s especially difficult, move on to the next one. This prevents you from getting bogged down and wasting time. You can always return to the more challenging ones later if you have time.

  • Eliminate Clearly Wrong Answers: If you don’t know the answer right away, try to eliminate at least one or two of the answer choices. This increases your chances of selecting the correct answer.

  • Read Each Question Carefully: Pay close attention to the wording of each question. Words like “always,” “never,” and “most likely” can change the meaning of the question and affect the correct answer.

  • Pacing: Keep an eye on the time, and avoid spending too long on a single question. The CNOR exam has 200 questions, so you need to pace yourself. Aim to answer each question in about 1 minute.

5. Take Practice Exams Regularly

Practice exams are one of the most effective ways to prepare:

​

  • Timed Practice Tests: Simulate real exam conditions by timing yourself. This can improve your pacing and manage test-day anxiety.

  • Analyze Your Results: After each practice test, review your incorrect answers to identify your weaknesses. Focus on these areas in your future study sessions.

  • Set Goals: Aim to improve your score with each practice test, working toward a passing score for your state.
