Physical therapy does not fall under the traditional STEM umbrella of engineering, math, or physical sciences, but it is increasingly recognized as a STEM-adjacent field depending on the context. The answer changes based on whether you’re asking about federal degree classifications, undergraduate prerequisites, financial aid eligibility, or immigration benefits. For most practical purposes that matter to students, physical therapy programs carry enough scientific weight to qualify for several STEM-related benefits, even if the formal classification is complicated.
How Physical Therapy Is Officially Classified
The federal government assigns every degree program a Classification of Instructional Programs (CIP) code. Physical Therapy/Therapist holds CIP code 51.2308, which places it under “Health Professions and Related Clinical Sciences,” not under Engineering (14), Biological and Biomedical Sciences (26), Mathematics and Statistics (27), or Physical Sciences (40). Those four categories are the core STEM designations recognized by the Department of Homeland Security.
That said, the DHS STEM Designated Degree Program List does include select programs from the Health Professions series (CIP 51). The list has expanded over the years and now pulls in some health-related codes, though Physical Therapy’s specific code is not confirmed as one of them. So while PT sits in a category that overlaps with STEM, it is not a traditional STEM major by the strictest federal definition.
The Curriculum Is Heavily Science-Based
Whatever the classification says on paper, the coursework tells a different story. The American Physical Therapy Association lists the most common prerequisites for Doctor of Physical Therapy (DPT) programs, and the lineup reads like a science degree: two semesters of anatomy and physiology with labs, two semesters of biology with labs, two semesters of general chemistry with labs, two semesters of general physics with labs, plus statistics and psychology. That’s roughly 40 or more credit hours of pure science before you even start the graduate program.
Once inside a DPT program, the curriculum adds neuroscience, kinesiology, pathological physiology, movement dynamics, and clinical evaluation methods. Students learn to analyze dysfunction using measurement tools and design treatment plans grounded in biomechanical and physiological principles. The knowledge base overlaps significantly with biomedical science programs.
Common Undergraduate Pathways
Most students headed for PT school major in exercise science, kinesiology, biology, or a dedicated pre-physical therapy track. This is where classification gets interesting. Exercise Physiology and Kinesiology holds CIP code 26.0908, which falls under Biological and Biomedical Sciences, one of the four core STEM categories. If you major in exercise physiology or kinesiology as your undergraduate degree, that degree itself is STEM-designated even though the DPT you earn afterward may not be.
Biology majors are in the same position. A bachelor’s in biology is unambiguously STEM. So while the graduate PT degree occupies a gray area, the undergraduate path leading to it is often a full STEM program. This distinction matters for scholarships, immigration status, and how you present your education on applications.
STEM Benefits PT Students Can Access
The VA’s Edith Nourse Rogers STEM Scholarship explicitly lists Physical Therapy/Therapist (CIP 51.2307) and Pre-Physical Therapy Studies (CIP 51.1108) as approved fields of study. Veterans and dependents using GI Bill benefits can apply for additional funding through this STEM scholarship while pursuing PT. The broader category of Rehabilitation and Therapeutic Professions (CIP 51.23) is also approved.
For international students on F-1 visas, the picture is more nuanced. STEM OPT allows graduates with qualifying STEM degrees to extend their post-graduation work authorization by 24 months, for a total of 36 months instead of the standard 12. To qualify, your degree must appear on the DHS STEM Designated Degree Program List. If your DPT’s CIP code isn’t on that list, you wouldn’t qualify based on the DPT alone. However, USCIS allows students to use a previously earned STEM degree for the extension, as long as the practical training opportunity relates directly to that earlier degree. So if you completed a bachelor’s in kinesiology or biology (both STEM-designated) before your DPT, you could potentially use that undergraduate degree to qualify for the 24-month STEM OPT extension.
Why the STEM Label Keeps Coming Up
Modern physical therapy practice relies heavily on technology and quantitative analysis in ways that blur the line between health care and applied science. Biomechanics, a core component of PT, uses principles from physics and engineering to study how the body moves and responds to force. Researchers and clinicians routinely use infrared motion capture systems, force plates, and wireless muscle activity sensors to collect movement data. That data gets processed through statistical software and factor analysis, the same mathematical methods used in engineering research.
Rehabilitation technology has also pushed PT further into STEM territory. Digital motion modeling, wearable sensors, and data-driven treatment planning all require practitioners to interpret complex datasets. A physical therapist analyzing gait mechanics is doing applied physics. One designing a progressive loading program for a torn ligament is working from tissue biology and biomechanical engineering principles.
What This Means for Your Planning
If you’re choosing an undergraduate major with an eye toward PT school, picking a STEM-classified program like exercise physiology, kinesiology, or biology gives you the formal STEM designation at the bachelor’s level. This opens doors to STEM scholarships, research funding opportunities, and, for international students, a stronger immigration pathway after graduation.
If you’re already in a DPT program and wondering whether your degree “counts” as STEM for a specific purpose, check the exact program you need. VA STEM scholarships include PT. The DHS STEM OPT list requires you to verify your program’s CIP code against the current designated list, which your school’s international student office can confirm. The answer isn’t a universal yes or no. It depends on which door you’re trying to open.
