How long does it take to become an OHN?

Prospective OHNs usually earn a BSN, which can take up to four years in a traditional program, and then apply for an RN license. A master's or doctoral program requires 2-5 more years of study. Many employers prefer to hire nurses with occupational health certifications that require a minimum of 3,000 clinical hours.

What is the difference between COHN and COHN-S certification?

The COHN certification focuses primarily on clinical practice. This credential best serves nurses who spend more than 50% of their time providing direct patient care and performing tasks such as spirometry or audiology. Nurses who spend more than half of their time in management and administrative practice, engaging in policy development, program planning, and budget and fiscal areas, benefit from COHN-S certification.

Can a licensed practical nurse or licensed vocational nurse (LPN/LVN) be an OHN?

An LPN/LVN may work as an OHN only under an RN or a medical supervisor. These positions require a high school diploma and completion of an approved LPN/LVN program. While LPNs/LVNs may find job opportunities in occupational health, most employers prefer to hire COHN-certified RNs who hold BSNs or graduate degrees.

What types of nursing experience are important for OHNs?

OHNs typically enter the field after earning an undergraduate nursing degree with specialties or gaining clinical experience in ambulatory care, critical care, emergency nursing, or community health. OHNs may decide to pursue a master's or doctoral degree to strengthen their professional competencies in advanced practice nursing, public health, and business.
