COHN Questions and Answers

What is the COHN certification?

The Certified Occupational Health Nurse (COHN) credential is awarded by the American Board for Occupational Health Nurses (ABOHN) to registered nurses who specialize in worker health, safety, and workplace injury prevention. It validates expertise in occupational health practice, case management, regulatory compliance, and health promotion within employer settings.

What is the format of the COHN exam?

The COHN exam is a computer-based test administered at PSI testing centers across the United States. Candidates have three hours to complete the exam, which uses multiple-choice questions with four answer options each. Results are provided immediately after submission at the testing center.

How many scored questions appear on the COHN exam?

The COHN exam contains 160 multiple-choice questions, of which 150 are scored and 10 are unscored pretest items used for future exam development. Candidates cannot identify which questions are pretest items, so every question should be answered carefully within the three-hour time limit.

What is the passing score for the COHN exam?

ABOHN uses a scaled scoring system where candidates must achieve a scaled score of 500 or higher to pass the COHN exam. The raw passing score is determined through a criterion-referenced method based on a modified Angoff study, ensuring the cut score reflects minimum competency for safe practice.

What topics does the COHN exam cover?

The exam covers four main domains: clinical and primary care (direct worker health services), case management (coordinating injury and illness recovery), worker and workplace health hazard assessment, and regulatory and legislative compliance including OSHA standards. Health promotion and disease prevention are integrated throughout these domains.

Who is eligible to sit for the COHN exam?

Candidates must hold an active, unrestricted RN license in the United States or its territories and have completed at least 3,000 hours of occupational health nursing experience within the previous five years, or 50 contact hours of continuing education in occupational health nursing within the past five years.

How do I register for the COHN exam?

Applicants register directly through the ABOHN website by submitting an online application, proof of RN licensure, documentation of occupational health experience, and the exam fee. Once ABOHN approves the application, candidates receive an Authorization to Test and schedule their exam appointment through PSI within a 90-day eligibility window.

What study resources work best for COHN preparation?

Effective preparation combines the AAOHN Core Curriculum for Occupational Health Nursing textbook, ABOHN's official candidate handbook and content outline, practice questions covering all four domains, and review of OSHA regulations and workers' compensation laws. Many candidates also attend AAOHN review courses offered as live workshops or self-paced online modules.
