Do you have to major in biology for PA school?

By The Prereq Club, a pre-PA student and her mom (not PAs or admissions advisers). Every program rule below names its source and the month we checked it: October 2026.

Short answer

No. In the 2024–25 entering class, 27.3% of new PA students majored in biology, so nearly three in four had a major other than "biology," though about 42% had a biology-related major. The programs we checked accept any major. What they require is a bachelor's degree and their prerequisite courses, and your grades in those courses matter.

Top 10 majors of 13,195 students who started PA school in the 2024–25 cycle, from PAEA's CASPA matriculation data as reported by The PA Life. Biology-related majors together (biology, biological sciences, biomedical science, human biology) were about 42%.

What programs say

  • UNC Chapel Hill: asked whether you need a health sciences degree, its answer is "No," as long as you have a bachelor's (or graduate) degree from a regionally accredited U.S. school and the required prerequisites.
  • Albany Medical College: "We accept baccalaureate degrees from any area of study but recommend a science-heavy curriculum."

Why your science grades still matter

CASPA calculates a separate science GPA and a biology, chemistry and physics (BCP) GPA from your classes, whatever your major. Students admitted through the 2024–25 CASPA cycle had a 3.68 cumulative undergraduate GPA and a 3.61 science GPA, according to PAEA data reported by The PA Life.

If you're not a biology major

  1. List every prerequisite for each program on your list, and map each one to a course you've taken or will take.
  2. Leave room in your schedule for prerequisites your major doesn't require.
  3. Check how CASPA will sort your classes, using CASPA's course subject list, so you know what lands in your science GPA.
