Physicians diagnose, treat, and counsel patients in clinics and hospitals, performing exams, interpreting tests, prescribing treatments, providing emergency care, and managing serious illnesses. They also conduct research, teach future healthcare professionals, and may lead medical centers. Because the field is broad, physicians specialize during training; accredited programs span more than 130 specialties, including cardiology, pediatrics, surgery, psychiatry, and dermatology. Aspiring physicians choose between an M.D. (doctor of medicine) or D.O. (doctor of osteopathic medicine) pathway, which differ in training approach but lead to the same career outcome.

Education, Training and Experience

• Medical School Preparation & Admissions
  • Most applicants complete a bachelor's degree, though only three years of college are required to apply.
  • Students without a science background can enroll in post-baccalaureate programs to complete prerequisites.
  • Research medical schools early to understand requirements and fit.
  • Applications require transcripts, letters of recommendation, and MCAT scores.
  • The MCAT tests problem-solving using concepts from biology, chemistry, physics, biochemistry, psychology, and sociology.
  • The AMCAS system allows applicants to submit one application to multiple schools.
• Medical School Curriculum
  • Medical school lasts four years: basic sciences plus clinical rotations.
  • Some schools introduce clinical experience earlier than traditional models.
  • Curricula may be systems-based, case-based, or a hybrid.
  • Increasing numbers of schools offer dual-degree options (e.g., MD/MPH, MD/MBA, MD/PhD).
• Residency
  • After earning an M.D., students enter residency in their chosen specialty, lasting 3–8 years depending on discipline.

Detailed Work Activities
