Frequently Asked Questions

What is the COHN-S certification?

The COHN-S (Certified Occupational Health Nurse-Specialist) is an advanced credential awarded by the American Board for Occupational Health Nurses (ABOHN) to registered nurses who demonstrate expertise in occupational health nursing. It emphasizes specialist roles such as administration, management, education, consultation, and case management in workplace health and safety programs.

To be eligible, you must have:

  • A current, unrestricted Registered Nurse (RN) license in the United States or Canada.
  • A minimum of 3,000 hours of experience in occupational health nursing within the last five years. Experience can be in clinical, case management, safety, consulting, or administrative roles.
  • At least 50% of your current role must be dedicated to occupational health.

What are the main content areas covered on the exam?

The exam blueprint is typically divided into four major categories related to the Occupational Health Nurse Specialist's role:

  • Program Management and Quality Assurance
  • Operations and Business Management

What is the passing score for the COHN-S exam?

The COHN-S exam uses a scaled scoring system with a passing score of 70 out of a possible 100 points. This scaled score accounts for variations in exam difficulty and ensures consistent standards across different test administrations.

How should I prepare for the COHN-S exam?

A comprehensive study plan is essential. Successful candidates often use:

  • The official ABOHN Study Guide and Content Outline.
  • COHN-S review courses (both in-person and online).
  • Use Prephow Practice tests and question banks to familiarize themselves with the exam format.
  • Key reference textbooks on occupational health and safety.

How do I apply for the COHN-S exam?

You apply through the credentialing body, the American Board for Occupational Health Nurses (ABOHN). The process involves submitting an application online through their website, providing documentation of your RN license and experience, and paying the examination fee.

What's the difference between the COHN and COHN-S certifications?

  • The COHN is the entry-level certification for general occupational health nurses focusing on clinical practice, requiring an associate degree or diploma and 3,000 hours of experience.
  • The COHN-S is for advanced specialists with managerial roles, requiring a bachelor's degree and the same experience level. You can only hold one core credential at a time.
