A Physician Assistant is a health care professional licensed to practice medicine with the supervision of a licensed physician.
The education of a Physician Assistant is based on the medical school model, although unlike medical school which lasts four years, Physician Assistant training is usually two to three years in duration.
It is generalist in approach, consisting of classroom and laboratory instruction in medical and behavioral sciences, such as anatomy, microbiology, pharmacology, pathophysiology, clinical medicine, and physical diagnosis, followed by clinical rotations in internal medicine, family medicine, surgery, pediatrics, obstetrics and gynecology, emergency medicine, and geriatric medicine, as well as elective rotations.
