What is a Physician Assistant?

  • A PA is a nationally certified and state-licensed medical professional.
  • PAs practice medicine on healthcare teams with physicians and other providers.

They practice and prescribe medication in all 50 states, the District of Columbia, the majority of the U.S. territories and the uniformed services.

How are PAs educated and trained?

  • Most programs are approximately 26 months (three academic years) and require the same prerequisite courses as medical schools. Most programs also require students to have about three years of healthcare training and experience.
  • Students take courses in basic sciences, behavioral sciences and clinical medicine across subjects such as anatomy, pharmacology, microbiology, physiology and more.
  • They then complete a total of more than 2,000 hours of clinical rotations in:
    • Family medicine
    • Internal medicine
    • Obstetrics and gynecology
    • Pediatrics
    • General surgery
    • Emergency medicine
    • Psychiatry

How are PAs certified and licensed?

Before they can practice, PAs who graduate from an accredited program must:

  • Pass the PA National Certifying Exam (PANCE) administered by the National Commission on Certification of PAs
  • Get licensed by the state they wish to practice in

In order to maintain certification, PAs must:

  • Complete a recertification exam every 10 years
  • Complete 100 hours of continuing medical education (CME) every two years

The "PA-C" after a PA's name means they are currently certified.
