Major in Biology
If you’re fascinated by the origins and functions of animals, plants and microbes, a B.A. or B.S. in biology is a great choice for you.
A major in biology provides an excellent foundation for careers in everything from medicine to public health to environmental and industrial applications.
At Elmhurst, you’ll learn to solve problems and make discoveries. In collaboration with Ph.D.-level faculty, you’ll conduct cutting-edge research, present at national conferences and even co-author papers that contribute to scientific knowledge. And you’ll graduate as a broadly trained biologist.
Choose Your Bachelor’s Degree
Biology majors at Elmhurst choose between the bachelor of science (B.S.) degree and the bachelor of arts (B.A.).
- The B.S. incorporates more coursework in science and math, making it a good choice for students who plan to pursue graduate work in biology or a career in the health sciences.
- The B.A. offers more flexibility in choosing electives.
Preparing for Professional and Graduate School
If you plan to go on to medical school, dental school or another professional or graduate program, we’ll help you choose elective courses best suited to your goals. See your faculty advisor for details. In addition, students interested in entering a health profession can meet with the health professions advisor.

Biology majors interested in careers in medicine, dentistry, and veterinary medicine can apply for early admission to select programs the University has agreements with.
Students interested in these tracks will pursue a biology major along with other requirements for these fields (academic and co-curricular). Information about each affiliation and the requirements can be found on the Health Professions Advising pages and in the 2024-2025. In addition, students must meet with their biology faculty advisor and the health professions advisor to discuss all requirements and to determine their eligibility to apply.
Some affiliations require specific majors, GPAs, and entrance exam scores and limit transfer credit. Admission to Elmhurst University does not guarantee admission to an affiliate partner.

- Sophomore year: BIO 315 and one biology elective, CHM 311 and 312, mathematics, statistics
- Junior year: Two biology electives, one year of physics (for B.S.)
- Senior year: Two biology electives, BIO 498
Minor in Biology
A minor in biology provides an excellent foundation for a career in education, pharmaceuticals, health care businesses and much more.
Many students choose a biology minor as a complement to a science-related major, like chemistry or nursing. It’s also a great choice for students in unrelated majors who simply want to pursue an interest in plant and animal life.
The minor consists of five courses with a grade of C- or better in each course:
- BIO 200
- BIO 201
- Three electives at the 300 or 400 level
At least three of the five courses must be taken at Elmhurst University. BIO 100, 104, 105, 107, 108, 221, 300, 301 and 449 may not be applied toward the minor. One year of chemistry (CHM 101 and CHM 103, or CHM 211 and CHM 212) is also recommended.
