Are you, or do you know an OHN who is thinking of becoming ABOHN Board Certified? 

ABOHN is offering a one-time partial rebate on the examination fee. Due to COVID-19, we are extending the deadline. August 31, 2020 is the last day to sit the examination(s) and receive the rebate.  Please note that the ABOHN BOD is constantly monitoring the situation and will make changes as necessary.

ABOHN examinations are consistently monitored for industry relevance and our 2018 Practice Analysis determined that many tasks that OHNs do have changed enough to warrant exam re-development. Over the past year, the Exam Development Advisory Committee (EDAC), made up of current ABOHN credential holders, have written and reviewed new exams for the Certified Occupational Health Nurse (COHN), Certified Occupational Health Nurse – Specialist (COHN-S), and Case Management (CM) credentials. Building on the EDACs achievements, ABOHN now needs a cohort of applicants to take the new exams.

Why the one time offer to rebate ½ of the examination fee?

ABOHN needs a significant number of applicants to take the exams so the final vetting and cut scores can be determined. Those that take an exam during the rebate period will not receive their exam results until ABOHN can set a final cut score. While we realize that this is an inconvenience, it is necessary for our exam development. 

The application process and fees are:

· Submit an application and required documentation to the ABOHN office for the COHN, COHN-S and CM with the non-refundable $150.00 application fee.

· After acceptance into Candidate status, an invoice will be sent for the exam fee which must be paid in full. $400.00 for the COHN and COHN-S. $250.00 for the CM.


Those who schedule and take the exam during the exam rebate fee period will receive a rebate check with their official scores.

COHN/COHN-S Rebate =$200.00

CM Rebate = $125.00

Certification is a voluntary mechanism for validating professional knowledge and expertise in a specialty. In contrast to licensure, which assures the public of safe practice at a beginning level, certification reflects specialty practice and knowledge at a proficient level. By meeting the challenge of certification, the certified individual has made a commitment to a specialty and to continued professional growth and development. Certification is recognized by employers and peers as an achievement and leads to employment opportunities, advancement, and professional prestige.

ABOHN uses the definition of occupational and environmental health nursing and the standards of practice, in addition to other criteria, to determine eligibility for certification. The American Association of Occupational Health Nurses, Inc. (AAOHN) establishes the definition and standards of specialty practice. The entire document is available from AAOHN National Office, 330 N. Wabash Ave, Ste 2000, Chicago, IL 60611. Telephone (312) 321-5173; Fax (312) 673-6719. Email is info@aaohn.org.

ABOHN has 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 qualifications. Both examination Blue Prints/Test Specifications can be found in the Handbooks, located on the website. IT IS HIGHLY RECOMMENDED that you choose the examination that fits your practice, not your level of education.

ABOHN currently offers two core credentials:

Certified Occupational Health Nurse COHN
Certified Occupational Health Nurse - Specialist COHN-S


 and one specialty credential:

Case Management CM
