About the Exam
What's on the test and how it got there.
Medical-surgical nursing is a specialty with a distinct body of
knowledge, skills and abilities that are validated by the Certified Medical-Surgical
Registered Nurse (CMSRN) certification from the Medical-Surgical Nursing Certification
Board (MSNCB).
MSNCB is transitioning to a new vendor, Data Recognition Corporation, who leverages the Pearson VUE testing network, for certification exams, causing a brief testing intermission from June 13–July 31, 2025. This will impact your 90-day testing eligibility if you apply for the CMSRN or CAVRN exam on or after March 15. MSNCB understands that, when it comes to achieving nursing excellence, the show must go on. During this pause, you are still welcome to apply for the certification exam.
IF YOUR APPLICATION IS APPROVED FROM MARCH 15–APRIL 8
- Your eligibility to test will be truncated at June 13.
- You will still have 65 days to schedule your exam if your application is approved on April 8.
IF YOUR APPLICATION IS APPROVED FROM APRIL 9–MAY 11
- Your eligibility to test will be extended to Aug. 27, without appointment availability from June 13–July 31.
- You will still have 60 days to schedule if your application is approved on May 11.
IF YOUR APPLICATION IS APPROVED FROM MAY 12–JUNE 8
- Your eligibility to test will be extended to Sept. 30, without appointment availability from June 13–July 31.
- You will still have 65 days to schedule if your application is approved on June 8.
IF YOUR APPLICATION IS APPROVED FROM JUNE 9–JULY 31
- Your eligibility to test will be granted on Aug. 1, and the 90-day eligibility policy will resume.
Exam Development
The Medical-Surgical Nursing Certification Board (MSNCB®) collaborates with our test
development partner, Prometric, to develop the CMSRN® exam.
The CMSRN exam is based on a job task analysis (JTA), conducted at least every five
years. A JTA is necessary to validate the tasks medical-surgical registered nurses
perform, and the knowledge, skills, and abilities needed to perform these tasks
competently to provide safe patient care.
For full details about how the CMSRN exam is developed, see Appendix B in the CMSRN
Certification Handbook.
Exam Details
150 Questions
The CMSRN exam has 150 multiple choice questions. 125 of the
questions are scored, and 25 questions are unscored to gather statistical data on
item performance for future test forms.
3 Hours
You have three (3) hours to complete the exam. We recommend you
arrive at the testing center or launch the remote proctored exam application thirty
(30) minutes before the start of your exam.
95 Passing Score
A standard score of 95, equal to approximately 71% correct, is
required to pass the CMSRN exam. Your raw score is the number of questions you
answered correctly out of the 125 scored questions. Your raw score is converted to a
standard score to allow for comparison across different exam versions.
These scores reflect the 2023 CMSRN
Exam Blueprint, which through a job task analysis, was adjusted based on current
trends in healthcare delivery. This job task analysis and modifications take place every
five years, and there has been no substantial change in the pass rate for the past
twenty years.
