MD

What is an MD?

The MD (Medical Doctor or Doctor of Medicine) is the professional qualification required to practise medicine as a physician in the United States and Canada. The MD is awarded after completion of a 4-year graduate-entry medical education programme (requiring a bachelor’s degree for entry) and is followed by residency training (3–7 years depending on specialty). The MD differs from the MBBS (Bachelor of Medicine, Bachelor of Surgery) used in the UK and Commonwealth systems, which is a 5–6 year undergraduate-entry or 4-year graduate-entry degree. The MD also differs from DO (Doctor of Osteopathic Medicine), which is an equivalent US degree with additional emphasis on osteopathic manipulative treatment but leading to identical practice rights and physician licensing. An MD is prerequisites to postgraduate residency training, specialty board certification, and independent medical practice. The MD is accredited by the Liaison Committee on Medical Education (LCME) in the US and the Committee on Accreditation of Canadian Medical Schools (CACMS) in Canada.

Year 3: Clinical rotations (core clerkships)

All students complete mandatory rotations:

• Internal Medicine (8 weeks): inpatient and outpatient
• Surgery (8 weeks): operating room, inpatient
• Paediatrics (6 weeks): inpatient and outpatient
• Obstetrics and Gynaecology (6 weeks)
• Psychiatry (6 weeks)

• USMLE Step 2 CS (Clinical Skills): practical exam with standardised patients (if taken; increasingly optional as of 2024)

Year 4: Advanced rotations and residency preparation

• Advanced clerkships (24–32 weeks): chosen specialties, research or electives in career-interest areas
• Sub-internship: 4-week intensive sub-internship role (acts as intern; high-stakes evaluation for residency match)
• Scholarly project or thesis (required at most schools; 4–8 weeks research time)
• Residency application and interviews (September–March typical): ERAS (Electronic Residency Application Service) submission, interviews at 15–30 programmes, residency match process (March match typically)
• Board preparation: preparation for USMLE Step 3 (taken during postgraduate Year 1 residency)

Assessment

• USMLE exams (US Licensing Exams):
  • Step 1: knowledge-based, typically end of Year 2 (score-report only, no pass/fail, as of 2022)
  • Step 2 CK: clinical knowledge, typically during Year 3 (numerically scored)
  • Step 2 CS: clinical skills, optional as of 2024
  • Step 3: taken during PGY-1 residency
• Clerkship grades: H (high pass), P (pass), LP (low pass), F (fail); typically 3–5 rotations per year; grades matter for residency competitiveness
• Dean’s letter (MSPE–Medical Student Performance Evaluation): cumulative assessment by school, critical document for residency application

Funding

Scholarships and grants

• Merit scholarships: limited (5–10% of students, typically 20–50% tuition reduction); some schools offer full-ride scholarships to top candidates (rare)
• Diversity scholarships: dedicated funding for underrepresented minorities, first-generation, low-income backgrounds (10–20% of cohort at some schools)
• Public service scholarships: some schools offer tuition reduction/forgivable loans to graduates committing to underserved areas (National Health Service Corps scholarship)
• Military scholarships: HPSA (Health Professions Scholarship Program) provides full tuition + living stipend for military service commitment (typically 4 years active duty or equivalent)
• Specific institution funding: varies widely; some private schools more generous than others

US Federal Loans

• Direct Unsubsidized Loan: available to US citizens and permanent residents; up to USD 20,500 per year (aggregate cap ~USD 138,500 for graduate study)
• Grad PLUS Loan: available to US citizens and permanent residents; available for unmet costs (school cost of attendance minus other aid); interest ~8.25% (2024 rate, varies annually)
• Average medical school debt: USD 200,000–250,000 (range USD 0–500,000+ depending on funding and school type)

Loan forgiveness and repayment

• Public Service Loan Forgiveness (PSLF): available for graduates in government or non-profit roles; remaining balance forgiven after 120 qualifying payments (10 years typical); common for primary care or underserved community physicians
• Physician Loan Repayment Program (PLRP): federal programme offering USD 25,000–40,000 towards student loans for service commitment to underserved areas
• Income-driven repayment plans: available for federal loans; monthly payments tied to income; remaining balance forgiven after 20–25 years (taxable event)

International students

• International students (non-US citizens without permanent residency) have limited access to US federal loans
• Private education loans available (Prodigy Finance, Sallie Mae, Earnest, etc.) at variable rates (9–14% APR); require US credit history or co-signer
• International medical schools increasingly popular for cost reasons (Caribbean, Mexico, Canada, UK options available to US citizens and international students at lower cost, but matching into US residency more competitive for foreign graduates)

Career outcomes

MD holders (after residency training) pursue:

1. Primary care practice (~30%): family medicine, internal medicine, paediatrics; median salary USD 180,000–220,000 (ranges to USD 250,000+ in high-demand areas)
2. Specialty practice (~35%): radiology, dermatology, ophthalmology, orthopedic surgery (highest salaries USD 300,000–600,000); paediatric specialties, psychiatry (USD 200,000–300,000)
3. Academic medicine (~10–15%): faculty position in academic medical centre; combination of clinical work, teaching, research; median USD 180,000–280,000
4. Hospital leadership or administration (~5–8%): chief medical officer, medical director, health system leadership
5. Research (~2–5%): physician-scientist roles combining clinical practice and laboratory research (especially for those pursuing MD/PhD)

Earnings and employment: Physician income varies widely by specialty, geography, and setting. US physician median income ~USD 210,000 (range USD 140,000–600,000+ by specialty). Supply of physicians relatively balanced; employment outcomes typically high (>95% match into residency for US graduates from LCME-accredited schools).

International practice: US MD is not automatically recognised outside US/Canada; international practice typically requires additional licensure or equivalency exam (e.g., FMGE in India, PLAB in UK). Foreign medical graduates (non-LCME trained) increasingly common in US residency but face more competitive match process.

Related degrees

• DO (Doctor of Osteopathic Medicine): equivalent to MD in US; additional training in osteopathic manipulative treatment; identical licensing and practice rights; approximately 25% of US medical school enrollment
• MBBS (Bachelor of Medicine, Bachelor of Surgery): See related comparison below; international equivalent (5–6 years undergraduate-entry or 4 years graduate-entry); not equivalent to MD in US practice but holder may pursue additional training
• MD/PhD: dual degree (8–9 years total); integrates medical school and PhD research; supported by NIH (National Institutes of Health) funding; pathway to academic medicine/physician-scientist roles
