Common Questions

What are the advantages of seeing a PA for medical care?

PA education and practice emphasize patient education, preventive care, and chronic care management. PAs’ generalist medical training enables them to provide a wide spectrum of patient care and treat the “whole patient.” For example, during an appointment with a PA working in cardiology, in addition to discussing the patient’s heart issues, a PA might notice a skin condition and either treat it or refer that patient to a dermatology practice. PAs make it easier for patients to get the care they need when they need it. A 2014 Harris Poll found that 92 percent of Americans who have seen a PA or have a family member who has seen a PA said that having a PA makes it easier to get a medical appointment.*

* “Attitudes Toward PAs: A 2014 Survey by the American Academy of PAs.” The Harris online survey was conducted September 15–22, 2014 among 1,544 adults age 18 and older living in the US, including an oversample of 680 adults who have seen a PA and/or have accompanied a loved one to see a PA in the past 12 months.

What is a PA?

PAs (physician associates/physician assistants) are licensed clinicians who practice medicine in every specialty and setting. Trusted, rigorously educated and trained healthcare professionals, PAs are dedicated to expanding access to care and transforming health and wellness through patient-centered, team-based medical practice.

What education does a PA have?

PAs are educated at the master’s degree level. There are more than 300 PA programs in the country and admission is highly competitive, requiring a bachelor’s degree and completion of courses in basic and behavioral sciences as prerequisites. Incoming PA students bring with them an average of more than 3,000 hours of direct patient contact experience, having worked as paramedics, athletic trainers, or medical assistants, for example. PA programs are approximately 27 months (three academic years), and include classroom instruction and more than 2,000 hours of clinical rotations.

What is included in the PA school curriculum?

A PA’s medical education and training are rigorous. The PA school curriculum is modeled on the medical school curriculum that involves both didactic and clinical education training.

In the didactic phase, students take courses in basic medical sciences, behavioral sciences, and behavioral ethics.

In the clinical phase, students complete more than 2,000 hours of clinical rotations in medical and surgical disciplines, including family medicine, internal medicine, obstetrics and gynecology, pediatrics, general surgery, emergency medicine, and psychiatry.

What do PAs do?

PAs’ specific duties depend on the setting in which they work, their level of experience, their specialty, and state laws.

Generally, PAs can:

  • Take medical histories
  • Conduct physical exams
  • Diagnose and treat illness
  • Order and interpret tests
  • Develop treatment plans
  • Prescribe medication
  • Counsel on preventive care
  • Perform procedures
  • Assist in surgery
  • Make rounds in hospitals and nursing homes
  • Do clinical research
Where do PAs work?

There are more than 168,000 PAs who practice in every medical setting in all 50 states and the District of Columbia. They work in hospitals, medical offices, community health centers, nursing homes, retail clinics, educational facilities, workplace clinics, and correctional institutions. PAs also serve in the nation’s uniformed services and work for other federal government agencies, such as the Department of Veterans Affairs.


How do PAs work with physicians?

PAs are committed to team practice with physicians and other healthcare providers. Currently, most state laws require PAs to have an agreement with a specific physician in order to practice. These agreements were included in early PA practice acts 50 years ago when the PA profession was new and untested.

Today, PAs are still held to these obsolete requirements despite the PA profession being well established, highly trusted, and essential to the U.S. healthcare workforce.

In 2017, the American Academy of PAs passed new policy called Optimal Team Practice. Optimal Team Practice occurs when PAs, physicians, and other healthcare professionals work together to provide quality care without burdensome administrative constraints.

To support Optimal Team Practice, states should: eliminate the legal requirement for a specific relationship between a PA, physician or any other healthcare provider in order for a PA to practice to the full extent of their education, training and experience; create a separate majority-PA board to regulate PAs or add PAs and physicians who work with PAs to medical or healing arts boards; and authorize PAs to be eligible for direct payment by all public and private insurers.

Is there a high demand for PAs?

Yes. The PA profession is one of the fastest growing in the country. The demand for PAs increased more than 300 percent from 2011 to 2014, according to the healthcare search firm Merritt Hawkins. The U.S. Bureau of Labor Statistics projects that the profession will increase 28 percent from 2021 to 2031, significantly faster than the average for all occupations. The demand for PAs is so high that three quarters of PAs receive multiple job offers upon graduation.

What is the public perception of PAs?

PAs are trusted healthcare providers. A 2022 NCCPA study found that over two thirds of respondents reported having received medical care from a PA. The same study found more than 93% of patients were satisfied with medical care rendered by a PA. Respondents reported that they believed PAs are well educated in medicine and have more time to spend with patients regarding their medical concerns.*

Likewise, a 2014 Harris Poll found extremely high satisfaction rates among Americans who have seen a PA or have a family member who has seen a PA. The survey found that 93 percent regard PAs as trusted healthcare providers and 91 percent believe that PAs improve the quality of healthcare.**

PA History & Milestones

The PA profession was created to improve and expand healthcare. In the mid-1960s, physicians and educators recognized there was a shortage of primary care physicians. To help remedy this, Eugene A. Stead Jr., MD, of the Duke University Medical Center, put together the first class of PAs in 1965. The first PA class graduated from the Duke University PA program on Oct. 6, 1967.

What is AAPA?

Founded in 1968, the American Academy of Physician Associates is the national professional society for PAs (physician associates/physician assistants). It represents a profession of more than 168,000 PAs across all medical and surgical specialties in all 50 states, the District of Columbia, U.S. territories, and the uniformed services.
