A physician assistant (PA) is a medical professional who works as part of a team with a doctor. A PA is a graduate of an accredited PA educational program who is nationally certified and state-licensed to practice medicine with the supervision of a physician.
PAs perform physical examinations, diagnose and treat illnesses, order and interpret lab tests, perform procedures, assist in surgery, provide patient education and counseling and make rounds in hospitals and nursing homes. All 50 states and the District of Columbia allow PAs to practice and prescribe medications.
The PA educational program is modeled on the medical school curriculum, a combination of classroom and clinical instruction. The PA course of study is rigorous and intense. The average length of a PA education program is 27 months.
