Certified Radiology Nurse Exam Information

The Certified Radiology Nurse (CRN) exam will be a computer-based exam consisting of 150 multiple choice questions.  The CRN exam will be administered four times annually, during the months of January, April, July and October.  Candidates, once approved to sit for the exam will be provided with the information for booking their exam at a date and location of their convenience.  To prepare for the exam please Download the CRN Exam BluePrint Radiology Practice Modality Areas.

Exam Scoring and Candidate Feedback/Results

The examinations are Pass or Fail only. The method used to set the passing score for the examinations is in accordance with standard criterion-referenced passing score standards. The members of the Board, who possess extensive knowledge about the current practice of radiology nursing in a variety of settings, set the passing score for each form of the examination. The passing score is set using generally accepted psychometric principles and methods to determine what constitutes a competent radiology nurse. Each candidate is measured against a standard of knowledge, not against the performance of other individuals taking the examination.

The score on the Radiology Nursing Certification Examination is reported as a standard score which summarizes the candidate’s performance on the entire exam. To reach the passing standard score of 95, the candidate must answer 73% of the questions in the total exam correctly. Candidates who are not successful on the test receive a breakdown of their performance by the Radiology Practice Modality Areas of the test blueprint to indicate areas of strength and /or weakness.

Incomplete Applications

Incomplete applications delay the review process and may preclude you from sitting for the examination. Incomplete applications will be held in a pending file until resolved.

Applicants will be notified of "pending" status in the event of incomplete applications by traceable means within 5 business days of receipt of the incomplete application.  Applicants will be requested to submit the missing materials within 5 business days.  Applicants will not be sent candidate materials until the applications are completed. RNCB will not process incomplete applications.

It is the applicant’s responsibility to obtain certificates, transcripts, and other documentation and maintain this documentation in case of an RNC audit to verify participation in continuing education activities. 

NALS, ENLS, ARLS, TNCC and ACLS certification and re-certification are counted toward certification and re-certification. These credits will apply only once per certification and/or re-certification, duplicate years of the same course are not counted during the certification and/or re-certification process.
