Saint Mary's University offers the first two years of an Engineering degree program accredited by the Association of Professional Engineers of the Provinces through the Canadian Accreditation Board. These first two years of study constitute the Diploma in Engineering. Upon completion of the Diploma in Engineering at Saint Mary's, students may choose to apply to Dalhousie University for the completion of their Bachelor of Engineering degree in their chosen discipline program. Required courses for the Diploma, as well as for each of the disciplines are listed below. Admission to the desired discipline program at Dalhousie University is not automatic and may depend on the applicant's academic standing and the number of available seats in the different programs. Students with low academic standings may be offered alternative disciplines. Dalhousie will treat students from the Associated University programs (of which Saint Mary's is a member) in the same manner as students who entered the program as freshmen at Dalhousie University. Academic merit will be the only deciding factor on admission to disciplines.
