Medical school is a form of post-baccalaureate education, but it is technically classified as a professional school rather than a traditional graduate school. The distinction matters for financial aid, degree classification, and how the programs are structured. In everyday conversation, people often lump medical school into “grad school” because it comes after a bachelor’s degree, and that’s not entirely wrong. But in academic and federal terminology, medical school occupies its own category.
Professional School vs. Graduate School
Universities generally draw a line between graduate programs and professional programs, even though both require a bachelor’s degree for entry. Graduate school refers to academic programs that offer master’s degrees or PhDs in specific disciplines. These programs emphasize research, scholarly work, and advancing knowledge in a field. A PhD student in biology, for example, spends years conducting original research and defending a dissertation.
Professional schools prepare students for careers in specific applied fields. Medical school, law school, pharmacy school, business school, and dental school all fall into this category. The University of Washington’s library system notes that “the distinction between graduate school and professional school can often be blurred, with professional school being brought into the graduate school fold, but there is a difference between the two.” Many universities house their medical school as a separate college within the larger institution rather than placing it under the graduate school’s administrative umbrella.
How the Federal Government Classifies Medical Degrees
The federal Integrated Postsecondary Education Data System (IPEDS) classifies the MD and DO as “doctor’s degree, professional practice.” This is a distinct category from the “doctor’s degree, research/scholarship” label applied to PhDs. The IPEDS glossary notes that these degrees “were formerly classified as first-professional” and lists medicine alongside law, dentistry, pharmacy, optometry, podiatry, and veterinary medicine. So at the federal level, a medical degree is not grouped with research doctorates or standard graduate degrees.
This classification has practical consequences. Federal student loan programs, for instance, group medical students under the “graduate or professional” borrowing category but offer higher loan limits for certain health professions programs. Medical students can access an additional $20,000 to $26,667 per year in unsubsidized federal loans beyond what standard graduate students receive, reflecting the significantly higher cost of medical education.
How Medical School Differs From a PhD
The biggest structural difference is the purpose of the training. An MD program teaches students to diagnose and treat patients. A PhD program trains students to conduct original research and contribute new knowledge to a field. These goals shape every aspect of the curriculum.
Medical school typically lasts four years and follows a defined sequence. The first two years focus on basic sciences: anatomy, physiology, pharmacology, and similar coursework delivered through lectures and lab work. The final two years shift to clinical rotations in hospitals and clinics, where students work with real patients under supervision. After graduation, new MDs must complete a residency (typically three to seven years depending on the specialty) before they can practice independently.
PhD programs have a more open-ended timeline, often running five to seven years. Students take courses in their discipline, pass qualifying exams, then spend years designing and executing original research. The program culminates in a written dissertation and an oral defense. There are no clinical rotations, no residency requirements, and no patient contact unless the research happens to involve clinical subjects.
Both paths require a bachelor’s degree as a starting point and both demand years of intense commitment. But an MD’s training revolves around applied clinical skills, while a PhD’s training revolves around producing new scholarship.
Why the Terminology Gets Confusing
Part of the confusion comes from the term “graduate medical education,” which is the official name for the residency and fellowship training that happens after medical school. The Accreditation Council for Graduate Medical Education (ACGME) defines this as “the period of education in a particular specialty or subspecialty following medical school.” So in medicine, “graduate” education refers to post-medical-school training, not medical school itself. A resident is a “graduate” of medical school undergoing further supervised training.
Another source of confusion is that many people use “grad school” casually to mean any schooling after college. By that informal definition, medical school qualifies. If someone asks whether you went to grad school and you attended medical school, saying yes is perfectly reasonable in normal conversation. The distinction between professional and graduate school is an academic and administrative one, not something most people worry about outside of financial aid forms or university governance.
What This Means for Admissions and Prerequisites
Like traditional graduate programs, medical school requires a completed bachelor’s degree. The degree can be in any discipline, though most applicants complete prerequisite coursework in biology, chemistry, physics, and math regardless of their major. The University of Wisconsin School of Medicine notes that in rare cases, applicants holding another professional degree (such as a pharmacy doctorate) may be admitted without a bachelor’s, but this is the exception.
Where medical school admissions diverge sharply from most graduate programs is the standardized testing and application process. Medical school applicants take the MCAT rather than the GRE, apply through a centralized system (AMCAS for MD schools, AACOMAS for DO schools), and face acceptance rates that are generally much lower than those of PhD or master’s programs. The application also places heavy weight on clinical experience, volunteer work, and letters from physicians, none of which are typical requirements for research-focused graduate programs.
The Short Answer
Medical school is post-baccalaureate education that shares some characteristics with graduate school, but it is formally classified as a professional school. The federal government, universities, and accrediting bodies all treat it as a separate category from research-focused graduate programs. For practical purposes like financial aid, medical students are grouped under “graduate and professional” students, which means many of the same federal loan programs apply, often with higher borrowing limits. If you’re filling out forms or comparing programs, the distinction matters. If you’re telling friends what you’re doing after college, calling it grad school is close enough.
