DEPARTMENT OF ELECTRICAL ENGINEERING
Degree of Bachelor of Science
in Electrical Engineering Requirements

The course of study of the degree of Bachelor of Science in Electrical Engineering takes five (5) academic years and one vacation school to complete and consists of 164 semester hours. The entire program follows and includes the general education requirements of the University of Liberia. Non-technical elective; must be in the humanities. A foreign language known to have body of scientific and engineering literature may be substituted for French and may also be used as a non-technical elective if continued past the second year. Technical electives may be chosen from upper level engineering, science or math courses but must have departmental approval.

The electrical engineering curriculum is firmly founded on a strong base in mathematics, physical and engineering sciences, social science and communication skills. Nearly half of the studies apply directly to the field of electrical engineering.

Inspection trips to engineering work and plants are made by electrical engineering students to supplement their theoretical studies.

Students desiring to major in Electrical Engineering should formally request of the chairman of the Division of Electrical Engineering admittance into the program upon his acceptance by the College of Science & Technology. Courses in addition to demonstrated proficiency and six (6) months of approved work experience is also required for graduation.
