COHN-S Exam Content Outline
Domains, priorities, and blueprint-based preparation
The official COHN-S blueprint defines the examinable scope. Use the domains below as a working checklist, but use the linked official outline for current weights and task statements.
Core Domains
- Clinical Occupational Health Practice
- Case Management & Workers’ Compensation
- Industrial Hygiene & OSHA Regulations
- Management & Program Leadership
- Research & Evidence-Based Practice

How to Build a Study Matrix
- Record the current official weight for every domain
- Mark each topic as explain, apply, or remediate
- Map every missed practice question to one domain
- Allocate more time to heavily weighted weak areas
- Recheck the official outline before the examination
