Common questions for new students

UNB's Diploma in Occupational Health and Safety (DOHS) is designed for supervisors, managers, and emerging OHS leaders. It is an advanced program designed to develop leaders in occupational health and safety, with a mixture of business management and specialized technical health and safety skills.


To be accepted into the DOHS program, you must have completed a UNB-approved OHS Certificate program or hold a current industry certification such as CRST® or CRSP®.


The diploma consists of four mandatory core courses and six additional elective courses, selected from a list of nine. All courses are open-access, meaning you can register and begin at any time of the year.

Each course consists of a cumulative exam that covers all the content of the course, as well as one assignment and one reflection paper. The exam is multiple choice and the assignment and reflection paper are submitted as an upload in your learning platform.

You have 13 weeks to complete each course, which requires approximately 52 hours of student engagement. Because the program is self-directed, you have the option of studying full- or part-time.

Explore DOHS courses


An overall grade of 70% is required to successfully pass each course. The grade will be based on the results of two written assignments and a final exam. Weighting of each item is available within the important course information in the D2L learning platform.

Each course involves approximately 52 hours of student engagement (i.e. time spent with your studies).

You have a target of 13 weeks in which to complete a course but may complete in less or more time, according to your own schedule.

Similarly, the self-paced nature of the DOHS allows you to complete the certificate according to your timeline. This means that some people may take up to two or more years to complete the program, while others complete it in as little as six months.


Life happens and sometimes we just need a little more time. We have you covered! If you need extra time to complete your course you can submit an extension request.


You can purchase courses one-by-one at a cost of $675 per course, or pay for the entire program upfront for $6,750. There are no additional fees or textbooks required.


Completing the Certificate in Occupational Health and Safety (COHS), and the Diploma in Occupational Health and Safety (DOHS), will give you the formal education requirements for certification as a Canadian Registered Safety Professional (CRSP®) by the Board of Canadian Registered Safety Professionals (BCRSP).

Occupational Health, Safety and Environmental work experience and professional development requirements must also be met to be eligible for certification.


The first step is to submit your application and supporting documentation. The DOHS program is open-entry and asynchronous, which means you can register and start the program at any time.

Submit your application

Once you have received your acceptance, you will be able to register for DOHS courses when you are ready.

NOTE: You will need to attach a copy of your prerequisite to your application.
