Graduate diplomas in engineering are awarded for the successful completion of a course at the advanced engineering undergraduate level which is aimed at broadening the education of a graduate engineer into areas which may not have previously been studied during the undergraduate training. Because the work which forms part of a graduate diploma may be a useful preparation for advanced work in a given area, under certain circumstances credit towards the Master of Engineering Science (Coursework and Minor Thesis) may be granted on the basis of the successful completion of a major portion of the graduate diploma. Such credit is limited to 25 per cent maximum of the MEngSc requirement.
