Learning Outcomes

Program Learning Outcomes, often referred to as ‘Program Standards', set out the essential learning that a student must achieve before being deemed ready to graduate.

In many cases these program learning outcomes were developed by the Ministry of Training, Colleges and Universities (MTCU) in consultation with employers and educators who are experts in the program field. To ensure the outcomes remain current and in line with industry needs, we invite our employers, graduates working in the field and current students to re-examine and update them during regular, ongoing program review focus groups.
