What is a Physician Assistant (PA)?
A Physician Assistant (PA) is a medical professional who diagnoses illness, develops and manages treatment plans, prescribes medications, and often serves as a patient’s principal healthcare provider. Working autonomously or in collaboration with other members of a healthcare team, PAs are integral to modern medicine. They are trained in a medical model, which allows them to approach patient care with a comprehensive understanding of disease processes and treatment strategies. The role of what is Physician Assistant has evolved significantly, making PAs essential providers across various medical settings.

Becoming a Physician Assistant: Education & Certification
To become a Physician Assistant, prospective students must complete a rigorous educational path. The primary requirement for entry into the profession is the completion of an accredited PA program. These programs are typically master’s degree level and usually last about 2-3 years. The curriculum is intensive, combining classroom instruction with extensive clinical rotations across various medical specialties.
The Physician assistant education requirements are demanding. Applicants to PA programs typically need a bachelor’s degree with a strong science background, including courses in anatomy, physiology, chemistry, biology, and microbiology. Most programs also require a significant amount of direct patient care experience, often ranging from 1,000 to 2,000 hours, gained through roles such as a medical assistant, EMT, paramedic, or nurse. This hands-on experience is crucial for developing clinical skills and understanding patient interactions prior to formal PA training.
Upon graduation from an accredited PA program, candidates must pass the Physician Assistant National Certifying Examination (PANCE), administered by the National Commission on Certification of Physician Assistants (NCCPA). Passing the PANCE grants the credential “PA-C” (Physician Assistant-Certified). To maintain certification, PAs must complete 100 hours of continuing medical education (CME) every two years and pass a recertification exam every ten years. This continuous learning ensures PAs remain up-to-date with medical advancements and best practices, reinforcing their commitment to high-quality patient care.
