For 20 years, the Certified Occupational Safety Specialist (COSS) program has helped workers master the core competencies necessary to be successful in the occupational safety and health field. COSS is ideal for those new to safety or someone looking for a refresher. The only prerequisite for COSS is a high school diploma.
The Certificate for Occupational Safety Managers (COSM) program is designed to help safety professionals advance in their careers. COSM offers specialized training for those with a minimum of 2 years of safety, health or environmental work experience.
