The Occupational Health and Safety (OHS) Diploma is an advanced program designed to develop leaders in the area of health and safety, with a mixture of business management skills and specialized technical health and safety skills. A differentiating theme throughout all courses is a focus on "system thinking" rather than "incident thinking".

The OHS Diploma consists of four core management courses that focus on giving a broad understanding of business, leadership, communications, workplace training, and decision-making. Six additional elective courses must also be taken. The workload for each course includes student engagement, online content, reading additional referenced materials, doing self-checks, assignments, and module exams.

This program is designed for supervisors, managers, and OHS leaders.
