Chiropractic School Prerequisites

Let me give you the straight version, because this is where a lot of students waste semesters. Most US Doctor of Chiropractic programs are built around one benchmark: roughly 90 semester hours of undergraduate coursework, with a substantial science core. But "most" is doing heavy lifting in that sentence — the details differ school to school, and the details are where wasted time hides.

The science core

Across programs, the recurring requirements are life and physical sciences: biology, general chemistry, organic chemistry or biochemistry, and physics — usually with lab components — plus coursework in English, psychology, and the humanities or social sciences. Some schools specify exact hour counts per subject. Some evaluate your overall science preparation holistically. GPA minimums exist and vary by school; check each program's current published requirement rather than a forum thread from three years ago.

Do you need a bachelor's degree?

Not everywhere. Some programs admit students who've completed the 90 hours without a finished degree — which can shave a year or more off the total path. Others require a completed bachelor's, and some states require a bachelor's for licensure regardless of what the school accepts. That last part matters: check the licensure rules in the state where you intend to practice, not just the admission rules of the school. This is exactly the kind of crossing-wire detail our interviews surfaced over and over — students who planned for admission but not for licensure.

Why picking your target schools early changes your transcript

Here's the move almost nobody makes. If you choose two or three target schools in your first year of college, you can map every science credit directly onto their requirements — no wasted electives, no missing lab, no surprise organic chemistry gap in your junior year. Choose late, and you're reverse-engineering a transcript that was built for a different plan. Early clarity is worth more than a perfect GPA.

Already partway through college — or done?

If you're mid-degree, do a gap analysis against your target schools this semester, not at application time. If you've already graduated in an unrelated field, you're not starting over — you're likely a handful of science courses away, and many programs are used to career-changers. Either way, the coursework question has a knowable answer; get it in writing from admissions, then build backwards.

FAQ

How many credit hours do you need for chiropractic school?

Most US programs require around 90 semester hours of undergraduate coursework with a science core — exact requirements vary by school.

What GPA do you need for chiropractic school?

Minimums vary by program and change over time — always check each school's current published requirement directly.

What classes should I take for chiropractic school?

Biology, general chemistry, organic chemistry or biochemistry, and physics (with labs where required), plus English, psychology, and humanities or social science coursework.

Can I get in without a science degree?

Often, yes — programs evaluate coursework, not your major. Career-changers with non-science degrees typically need to complete a set of specific science courses.
