COHN / COHN-S Eligibility

CORE CREDENTIALS

You may only hold one Core Credential, either the COHN or the COHN-S, you cannot hold both credentials. (For example: If you are currently certified as a COHN and decide that you meet the COHN-S requirements and would like to hold the COHN-S, you must first pass the COHN-S examination and then give-up the COHN credential once your official COHN-S passing results are confirmed.)

The COHN examination focuses on the OHN clinician practice.  The roles associated with the COHN credential are:  Clinician, Coordinator, Advisor and Case Manager.

Certified Occupational Health Nurse-Specialist (COHN-S)

PLEASE NOTE:  There are different education qualifications for the COHN and COHN-S examinations.  HOWEVER, if you qualify for both examinations, just having a higher degree does not necessarily mean you should take the examination with the higher degree qualification.  Both examination Blue Prints/Test Specifications can be found in each Handbook, and it is HIGHLY RECOMMENDED that you choose the examination that fits your practice, not your level of education.
