The American Board for Occupational Health Nurses (ABOHN) is an independent nursing specialty certification board and 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)
  • Case Management (CM)

ABOHN has certified approximately 14,000 and currently has 4,700 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.
