If you have earned (or will soon earn) a bachelor's degree or a degree in technology at a recognized college, university, or technical institution, you may be admitted as a graduate student and study for an advanced degree. There are three categories of graduate student: regular, associate, and non-degree. Only regular students can earn advanced degrees. Students who do not wish to enter a degree program may seek admission with non-degree status.
To be considered for admission as a regular graduate student, you should apply directly to the Department of Materials Science and Engineering. The decision to admit a student rests with the department. An offer of admission stands for one year following the semester for which the offer was made. If more than one year elapses, the department reserves the right to reconsider its offer.
