Finally passed my COHN exam after two attempts — here's what worked

Short answer: the COHN credential is for occupational health nursing, so its content centres on workplace health. That covers worker injury and illness management, case management, regulatory compliance, health promotion and program management. School nurses can sit for it if eligible, but much of the content is outside school nursing practice, which explains many near misses.

Check the credential fits

School nurses often pursue the school nurse certification instead, which matches their practice. If the district is asking for certification, confirm which credential it means before investing in a second attempt.

If COHN is the right credential

• Workers' compensation and case management: return-to-work planning and coordinating with employers and providers.
• Regulations: occupational safety rules, recordkeeping and confidentiality of employee health information.
• Hazards and surveillance: exposure monitoring, medical surveillance programmes and toxicology basics.
• Program management: needs assessment, budgeting and evaluation.

Study plan

1. Use the official exam blueprint and give more weight to areas outside your daily practice.
2. Study with occupational health nursing core references.
3. Do practice questions by domain and review every rationale.
4. Take a timed practice exam before rebooking.

Eligibility, the exam blueprint and retake rules are published by the American Board for Occupational Health Nurses.
