Graduate and Research Programme Graduate Credit in Electrical Engineering

Graduate credit is measured in “units.” A unit is a course at the graduate level taken for one semester, and which requires, as a prerequisite, preparation at the Bachelor’s level. Two units are given to a graduate course which continues for two semesters. Senior undergraduate courses as approved by the

Electrical Engineering Department may be allowed as credit for graduate students at one-half unit per semester. For each student, no more than two units total credit can be given to undergraduate courses.

Students transferring from other universities of recognized standing may be allowed a maximum of two units for graduate courses previously taken. No graduate credit is given for any undergraduate course taken at other universities.

A full-time student is permitted to take a maximum load of five units for a semester. For part-time students, the maximum load is reduced from five units per semester by one unit for each seven hours per week of employment or outside work. A co-operative graduate student attending two full days per week may be allowed up to 3 units.

The Master’s Degree Programme

The Master’s degree programme in Electrical Engineering is designed to be flexible, and to accommodate regular full-time and part-time students, and co-operative graduate students from industry.

A complete programme consists of at least ten units. Each student’s programme must be approved by the Electrical Engineering Department, and is worked out in advance with a professor who acts as an advisor.

The student’s course work is considered unsatisfactory, and he is required to discontinue, if more than one course in Electrical Engineering receives a grade below 66%, or more than two courses in fields other than Electrical Engineering receives a grade below 66%.

An essential ingredient in a graduate programme is opportunity for individual work. To be recommended for a Master’s degree in Electrical Engineering, a candidate must submit either a Research Thesis (EE 699) or an Engineering Report (EE 698). Topics are worked out in discussion with the faculty, and the project is done under the direct supervision of a professor of the Electrical Engineering Department, and is finally approved and accepted by that professor. A thesis under EE 699 may count either four or five units, and a project under EE 698, either one or two units. It is not possible to obtain credit under both EE 698 and EE 699 for the same degree.

All course work and thesis for Master’s degree must be completed within four consecutive academic years. It is possible for a full-time student of exceptional ability to complete the requirements for the Master’s degree in two semesters, or one academic year.
