An allopathic medical school is a school that awards a Doctor of Medicine (MD) degree and trains physicians to treat diseases using standard, science-based methods like medication, surgery, and radiation. There are currently 151 fully accredited allopathic medical schools in the United States. If you’ve heard the term and wondered how it differs from other types of medical training, the distinction mostly comes down to degree type, philosophy, and a few curricular differences.
What “Allopathic” Actually Means
Allopathic medicine is simply another name for conventional Western medicine. The National Cancer Institute defines it as a system in which doctors, nurses, pharmacists, and other professionals treat symptoms and diseases using drugs, radiation, or surgery. You’ll also see it called biomedicine, mainstream medicine, or orthodox medicine. In everyday conversation, when someone says “medical school” without any qualifier, they almost always mean an allopathic program.
The term exists mainly to distinguish MD programs from osteopathic medical schools, which grant a Doctor of Osteopathic Medicine (DO) degree. Both produce fully licensed physicians who can practice in any specialty, but their training has a few notable differences covered below.
How the Four-Year Curriculum Works
Allopathic programs follow a standard four-year structure split into two halves. The first two years focus on basic sciences: anatomy, physiology, biochemistry, pharmacology, pathology, and similar foundational coursework. Students spend most of their time in lecture halls, labs, and small-group learning sessions.
The second half shifts to hands-on clinical training. During year three, students rotate through core specialties like internal medicine, surgery, pediatrics, obstetrics and gynecology, psychiatry, and family medicine, typically spending about 42 weeks working alongside supervising physicians in hospitals and clinics. Year four opens up with roughly 38 weeks of sub-internships and elective rotations, giving students the chance to explore specific specialties before applying to residency programs.
Some newer programs have moved toward an integrated curriculum that blends clinical exposure into the first year, but the two-plus-two model remains the standard framework.
Accreditation and Oversight
Every allopathic medical school in the U.S. must be accredited by the Liaison Committee on Medical Education (LCME), which is recognized by the U.S. Department of Education and the World Federation for Medical Education. The LCME sets detailed standards covering everything from faculty qualifications and research infrastructure to student support services and curriculum design. Schools undergo periodic reviews to maintain their accreditation, and the standards are updated regularly.
This accreditation matters for students because graduating from an LCME-accredited school is a prerequisite for taking the national licensing exams and entering most residency programs.
Licensing Exams for MD Students
Allopathic students take the United States Medical Licensing Examination (USMLE), a three-step series spread across medical school and residency. Step 1 tests foundational science knowledge and is typically taken after the second year. Step 2 CK (Clinical Knowledge) evaluates a student’s ability to apply medical concepts to patient care and is usually completed during the fourth year. Step 3 comes during residency and assesses readiness for unsupervised medical practice. Passing all three steps is required for a full medical license.
This is one concrete difference from osteopathic students, who take their own licensing series called COMLEX-Level, though many DO students also choose to take the USMLE.
How Allopathic Schools Differ From Osteopathic Schools
The overlap between MD and DO training is substantial. Both require four years of medical school followed by residency, and graduates from either path can enter the same specialties and practice the same procedures. The key difference is curricular emphasis. Osteopathic programs include training in osteopathic manipulative treatment (OMT), a set of hands-on techniques involving stretching, gentle pressure, and resistance to diagnose and treat musculoskeletal problems. This adds extra coursework focused on the musculoskeletal system that allopathic programs don’t include.
Philosophically, osteopathic education places particular emphasis on holistic care and the body’s ability to self-heal, while allopathic training centers more squarely on evidence-based interventions. In practice, the day-to-day work of an MD and a DO in the same specialty looks very similar.
Getting In: Admissions Numbers
Allopathic medical schools are highly competitive. For the 2023-2024 entering class, the roughly 22,981 students who matriculated had an average MCAT score of 511.7 (out of 528) and an average GPA of 3.77. Students with math and statistics backgrounds posted the highest average MCAT at 516.1, while those from specialized health sciences had the lowest at 510.2, though all groups clustered in a relatively narrow range.
Beyond grades and test scores, most programs evaluate clinical experience, research involvement, community service, and personal qualities through interviews. The admissions process typically begins more than a year before enrollment, with applications opening in late May or early June through the AAMC’s centralized application service.
Cost of Attendance
Medical school is a significant financial commitment. Based on AAMC data from 2022-2023, the average annual tuition and fees at a public allopathic medical school ran about $37,080 for in-state students, while private schools averaged $58,889. Over four years, that puts total tuition somewhere between roughly $148,000 and $236,000 before accounting for living expenses, books, and equipment. Most students rely heavily on federal loans, and the total debt burden at graduation commonly exceeds $200,000.
Residency Match Rates
Graduating from an allopathic school provides a strong pathway into residency training. In the 2025 National Resident Matching Program (NRMP) results, 94.1% of U.S. MD seniors successfully matched into a first-year residency position. That rate has remained consistently high over the past decade, making allopathic graduates among the most competitive applicants in the match.
Residency programs last three to seven years depending on the specialty, and some graduates pursue additional fellowship training after that. Only after completing residency can a physician practice independently in their chosen field.
