What Is the CNOR Certification?

The CNOR credential is a professional certification for registered nurses working in perioperative nursing. It is administered by the Competency and Credentialing Institute, or CCI.

The certification recognizes registered nurses who demonstrate the knowledge and experience needed to provide safe and effective care before, during, and after operative or invasive procedures.

CCI states that CNOR is the name of the credential rather than an acronym whose letters represent a longer professional title.

CNOR certification is intended for experienced perioperative registered nurses. Nurses who have not yet completed the required experience may need to consider CCI’s foundational perioperative credential instead.

CNOR Eligibility Requirements

Applicants must satisfy all current eligibility requirements when they submit their application. CCI does not provide waivers for the standard requirements.

Standard Eligibility Pathway

Hold a current, unrestricted registered nurse license in the state or country where you currently practice.
Currently work full-time or part-time in perioperative nursing.
Work in clinical practice, nursing education, administration, research, or another qualifying perioperative role.
Have at least two years of experience as a perioperative registered nurse.
Have completed at least 2,400 hours of perioperative nursing experience.
Have completed at least 1,200 of those hours in the intraoperative setting.

Alternative Experience Pathway

Applicants who hold the CFPN credential, have earned a CST or TS-C credential, or hold the recognized military equivalent may qualify with:

At least 18 months of perioperative registered nursing experience
At least 2,400 total perioperative nursing hours
At least 1,200 hours in the intraoperative setting

CCI may randomly audit an application. Applicants selected for audit must provide employment, license, or experience documentation within the stated deadline.

Current CNOR Exam Format

The CNOR exam contains 200 multiple-choice questions. Of these, 185 questions contribute to the candidate’s score.

The remaining 15 questions are unscored pretest questions used to evaluate material for possible use on future examinations. They are mixed throughout the exam and are not identified.

Scored Questions

185 questions

Unscored Questions

15 pretest questions

Average Pace

About 68 seconds per question

Testing Method

Computer-based testing

An optional computer tutorial is provided before the examination. Tutorial time is separate from the three-hour-and-45-minute testing period.

Answer every question. An unanswered scored question may count against the final result, and candidates cannot identify which questions are unscored.

Individual Retake

CCI fees are generally nonrefundable. Active holders of another CCI credential and qualifying DAISY Award recipients may be eligible for a $40 discount, but discounts cannot be combined.

Testing Locations and Delivery Options

The CNOR examination is administered through PSI. Candidates may choose an in-person testing center or a remote-secure proctored exam when they satisfy the technical and testing-space requirements.

What Should I Expect on Test Day?

CNOR Test-Day Checklist

Confirm the examination date, time, delivery method, and location.
Complete the required system check before a remote examination.
Arrive or begin remote check-in before the scheduled appointment.
Bring an original, current government-issued photo ID containing a signature.
Make sure the identification name matches your CCI account.
Store or remove phones, watches, books, notes, bags, and unauthorized materials.

Answer every question before submitting the examination.

Candidates who arrive or begin remote check-in more than 15 minutes late may be considered absent and may forfeit the examination attempt and associated fee.

How Is the CNOR Exam Scored?

The number of scored questions answered correctly is converted to a scaled score ranging from 200 to 800.

A scaled score of at least 620 is required to pass.

A scaled score is not the percentage of questions answered correctly. It allows results from different exam forms to be reported using the same passing standard.

Candidates receive an immediate pass-or-fail notification after completing the exam.

Candidates who pass do not receive a detailed content-area breakdown. Candidates who do not pass receive a more detailed report from PSI, generally by email within 24 hours.

After a passing result, it may take up to five business days for the CNOR certificate to appear in the candidate’s CCI account.

Retaking the CNOR Exam

Candidates who do not pass may purchase another attempt directly through their CCI account.

Wait at least 30 days after the previous examination attempt.
Pay the $175 individual retake fee.
Schedule the new appointment through the CCI account and PSI.
Complete the retake before the 12-month eligibility period expires.
Retake the exam as many times as needed within the eligibility period, provided the waiting period and fee requirements are met.
Submit a new application and pay the current application fee if the 12-month eligibility period expires.

Candidates receive a different exam form when they retest. The detailed unsuccessful score report can help identify content areas requiring additional preparation.

Maintaining the CNOR Credential

The CNOR credential is valid for five years.

New certificants who earn the credential under the current system receive a five-year certification period beginning on the date they pass the examination.

Current Recertification Requirements

Maintain an active CNOR credential.
Maintain a current, unrestricted RN license.
Continue working full-time or part-time in qualifying perioperative nursing.
Complete at least 500 perioperative nursing hours during the five-year cycle.
Complete at least 250 of those hours in work that affects patient care in the intraoperative setting.
Earn 300 approved professional activity points.
Submit the recertification application and fee during the fifth year of the certification period.

Current CNOR recertification is completed through professional activity points. The credential cannot be renewed solely by retaking the CNOR exam.

How Can I Prepare?

CCI recommends allowing approximately three months for focused preparation.

Begin with a diagnostic practice test and organize missed questions according to the seven official content areas. Use your current clinical experience to reinforce familiar subjects while deliberately reviewing procedures, specialties, equipment, and emergencies you encounter less often.

CNOR Study Checklist

Review the current CNOR task and knowledge statements.
Study preoperative assessment, informed consent, site verification, and risk factors.
Review individualized care planning and expected patient outcomes.
Study positioning, skin preparation, sterile technique, and intraoperative monitoring.
Review medications, specimens, implants, counts, and retained-item prevention.
Study electrosurgery, lasers, tourniquets, robotics, and other surgical technology.
Review sterilization, disinfection, environmental cleaning, and infection prevention.
Study malignant hyperthermia, hemorrhage, fire, anaphylaxis, and other emergencies.
Review communication, handoffs, documentation, privacy, and patient education.
Study delegation, ethics, legal responsibilities, quality improvement, and evidence-based practice.
Complete full-length 200-question practice sessions within three hours and 45 minutes.
Review every missed answer and every correct answer obtained through guessing.

Question Strategy

Determine which phase of perioperative care the question addresses.
Identify whether the question asks for assessment, planning, action, or evaluation.
Prioritize patient identification, safety, asepsis, and immediate physiological threats.
Read carefully for words such as first, priority, best, immediate, and most appropriate.
Distinguish the circulating nurse’s responsibilities from those of other team members.
Choose actions consistent with professional standards and the RN scope of practice.
Answer every question because the unscored items cannot be identified.

Time-Management Strategy

Plan for an average of slightly more than one minute per question.
Answer straightforward questions without unnecessary delay.
Mark difficult questions for review when the system allows it.
Do not spend several minutes on one unfamiliar specialty procedure.
Monitor the testing clock at regular intervals.
Reserve time to review unanswered and marked questions.
