The Biology Major is designed for students with broad interests in the biological sciences. It is intended primarily to:

  1. prepare undergraduates for graduate studies in diverse areas of biology;
  2. prepare certain pre-professional students (e.g., medicine, veterinary medicine, dentistry) for advanced study in the health professions;
  3. provide a broad exposure to biology for students who want a general science education as biologists, and
  4. serve as initial preparation for students who later choose a more specialized major.

The major is offered by the College of Agricultural and Life Sciences and the College of Letters & Science. 

How to Get in

Biology Named Option

Instead of completing the requirements above, students may choose to select the named option below.

Honors in the Major

Admissions Criteria

Students admitted to the university and to the College of Agricultural and Life Sciences are invited to apply to be considered for admission to the CALS Honors Program.

New First-Year Students

  • Complete program application including essay questions

Transfer and Continuing UW-Madison Students

  • UW-Madison cumulative GPA of at least 3.25
  • Complete program application including essay questions

How to Apply

The application is available on the CALS Honors Program website.  Applications are accepted at any time.

New first-year students with accepted applications will automatically be enrolled in Honors in Research. It is possible to switch to Honors in the Major in the student’s first semester on campus after receiving approval from the advisor for that major.  Transfer and continuing students may apply directly to Honors in Research or Honors in the Major (after approval from the major advisor).

Requirements

All CALS Honors programs have the following requirements:

  • Earn at least a cumulative 3.25 GPA at UW-Madison (some programs have higher requirements)
  • Complete the program-specific requirements listed below
  • Submit completed thesis documentation to CALS Academic Affairs

Honors in the Major in Biology: Requirements

To earn Honors in the Major in Biology, students must satisfy the requirements for the major (above) as well as the following requirements:

  • Earn a 3.300 overall university GPA
  • Complete a two-semester senior honors thesis for 6 credits total and present research in a public forum
  • Complete at least 20 credits of honors coursework from the following sections of the Biology curriculum:
    • Introductory biology
    • Foundation courses
    • Upper-level breadth in the major
  • At least 6 of the 20 credits of honors coursework must be from the upper-level breadth in the major requirement

Learning Outcomes

  1. Know and understand core concepts that unify the breadth of biological sciences including: evolution; structure and function; information flow, exchange, and storage; pathways for transformations of energy and matter; and systems.
  2. Demonstrate practical skills of a professional biologist including: problem‐solving by engaging the process of science; written and verbal proficiency; laboratory skills; quantitative analysis skills; and teamwork skills.
  3. Graduates will be able to engage and make broader connections to other scientific disciplines and society.

Four-Year Plan

Four-year plans for the biology major are designed to support biological science major exploration. The four-year plan is a tool to assist you and your advisor in planning your academic career. Use it along with your DARS report and Course Search & Enroll. Your specific program of study could, and probably will, look different. You should customize your own four-year plan to fit your unique path at UW–Madison. Consult with your advisor about the best path for you.

Advising and Careers

Advising

Your advisor is here to guide you through the Biology Major. We can address your questions and concerns, provide advice, help you create a four-year degree plan that meets your major and professional goals, and connect you to resources. It is important to remember that advising is about the process, and some questions do not have a quick and easy answer. Your advisor will challenge you to self-reflect, to critically think about your goals and strategies, and to develop decision-making skills. For more information about what to expect during your advising appointment, visit UW Undergraduate Advising.

In the Biology Major, students are assigned to an advisor according to last name. Please schedule an advising appointment here.

Careers

The Biology Major encourages students to begin working on their career exploration and preparation soon after arriving on campus. We partner with the CALS Career Services office to help you leverage the academic skills learned in your major and liberal arts degree, explore and try out different career paths, participate in internships, prepare for the job search and/or graduate school applications, and network with professionals in the field (alumni and employers).

College of Agricultural and Life Sciences graduates are in high demand by employers and graduate programs. It is important to us that our students are career ready at the time of graduation, and we are committed to your success.

Career Resources:

Wisconsin Experience

The following opportunities can help students connect with other students interested in biology, build relationships with faculty and staff, and contribute to out-of-classroom learning:

  • Many study abroad programs offer a plethora of excellent upper-level biological science courses. Students often complete courses abroad that meet major requirements while others use this opportunity to focus on non-science coursework and explore other topics that interest them. Students can explore studying abroad as a Biology major utilizing the Biology Major Advising Page. Students work with their advisor and the CALS Study Abroad Office to identify appropriate programs. 

  • Students are encouraged to get involved in research in any life science department. Research can be performed for either course credit or pay, depending on the opportunity. Research opportunities can be identified by inquiring directly with faculty members, reading the Biology Major Newsletter, or announcement on the Student Job Center.
