Portland-State-University 2024-2025 Bulletin

Biology B.A./B.S.

Requirements

In addition to satisfying general University requirements, a student majoring in biology must meet general department requirements as well as fulfill the biology major requirements.

General requirements are completion of two terms of statistics or two terms of calculus; three terms of science majors’ introductory chemistry with laboratory; one term of organic chemistry; Ph 201 or Ph 231; Ph 214; and 12 elective credits from anthropology, chemistry, computer science, environmental science, geology, mathematics, physics, psychology, public health education, or statistics at the 200 level or higher. Courses used to meet any other general departmental requirement cannot also be used in the 12 elective credit area, and university studies courses are not accepted toward fulfillment of this requirement.

All biology majors must complete a minimum of 60 credits in biology including three terms of science majors’ introductory biology with laboratory. Of the 60 credits required for the major a minimum of 44 credits must be completed in upper-division biology specific coursework. 

Biology courses taken under the pass/no pass grading option are not accepted toward fulfillment of departmental major requirements, with the exception of courses numbered Bi 401, Bi 404, Bi 405, and Bi 406 which are offered with either the A-F or P/NP grading option, and Bi 407 Seminar which is only offered as P/NP. Of the 60 credits required in biology, a minimum of 46 credits must be in courses other than Bi 401, Bi 404, Bi 405, Bi 406, and Bi 407. Students may apply a maximum of 6 cumulative credits from the following research and experiential learning elective options Bi 401, Bi 404, Bi 405, Bi 406 toward fulfillment of the biology major credit requirements.

Biology majors interested in the Biology Honors Research Program may obtain information in the Biology Dept. Office.
