Graduate diplomas are intended to provide the equivalent of a major in a subject area that is different to your first degree's major. You may be eligible if you haven't studied for a degree before if you can demonstrate an interest in the subject area and a satisfactory academic ability.
A graduate diploma is a more in-depth version of a graduate certificate, is studied at undergraduate level, and can be completed in the equivalent of one year (two semesters) of full-time study.
To complete the qualifications, students need to gain 120 points at 100 level (first year papers) or above, including at least 80 points at 300 level (third year papers) or above, in the graduate diploma subjects.
