Who We Are and What We Do

The American Board for Occupational Health Nurses (ABOHN) is an independent nursing specialty certification board. We have over 12,000 active certified nurses working today.

ABOHN was founded in 1972 as an independent not-for-profit organization to set professional standards and conduct occupational health nursing specialty certification. ABOHN is the sole certifying body for occupational health nurses in the United States and awards three credentials: Certified Occupational Health Nurse (COHN), Certified Occupational Health Nurse - Specialist (COHN-S) and, Case Management (CM)..

ABOHN has certified approximately 16,000 and currently has 5, 200 active certificants.

We use predetermined standards of nursing practice to validate an individual registered nurse's qualifications, knowledge and practice in specific areas of occupational health nursing.

****  PRESS RELEASE ****


Hinsdale, IL --- October 12, 2012.  The American Board for Occupational Health Nurses, Inc. (ABOHN) is proud to announce in cooperation with our testing administrator and research coordinator Applied Measurement Professionals, the release of the 2011 Practice Analysis Report. 


The American Board for Occupational Health Nurses (ABOHN) is the sole provider of certification in the specialty of occupational health nursing in the United States.  ABOHN must ensure their certification examinations validly reflect the scope of current occupational health nursing practice by periodically conducting a practice analysis.  This report presents the findings of this research study. 


The primary purpose of this practice analysis was to confirm the knowledge, skills and activities currently required for the proficient practice of occupational health nursing as reflected by the tasks performed.   A valid and reliable survey instrument was developed by a practice analysis committee of subject matter experts. 


The survey contained 20 demographic questions and 136 nursing task statements.  An email invitation to participate in the web-based survey containing a link to the survey instrument was then distributed to 8,720 occupational health nurses in the United States and Canada.  After reducing the survey sample for undeliverable emails and addresses (n=2401), 6,319 surveys remained.  Respondents returned 2,594 surveys for a total response rate of 38.1%. Decision rules were developed to determine which tasks were appropriate for inclusion in the examinations.  The revised examination blueprints are used to refine the ABOHN certification examinations.


Since its inception in 1972, ABOHN has awarded the Certified Occupational Health Nurse (COHN), Certified Occupational Health Nurse-Specialist (COHN-S), Case Management (CM) and Safety Management (SM) credentials to more than 12,000 Occupational Health Nurses.
