Physician assistants (PAs) are among the fastest-growing professionals in healthcare. Today, there are approximately 190,000 PAs in practice, delivering over 590 million patient interactions annually, according to the National Commission on Certification of Physician Assistants. With the clinical expertise to work across specialties and care environments, PAs have become essential to meeting growing patient demand and mitigating persistent workforce shortages.
As healthcare demands outpace workforce capacity, physician assistants (PAs) are redefining how and where care is delivered. Their broad clinical training and flexibility across care settings enable them to step into critical roles that strengthen patient access, support continuity, and improve system-wide efficiency.
Looking ahead, the U.S. Bureau of Labor Statistics projects a 20% increase in PA job growth between 2024 and 2034, making the specialty one of the fastest-growing professions in healthcare.
While physician assistants already play a vital role in care delivery, locum tenens opportunities enable them to expand their reach even further—offering flexible solutions that strengthen clinical teams and support uninterrupted patient care.

Within the U.S., there are roughly 190,000 PAs according to the NCCPA.
As of October 2025, a little over 4% of physician assistants work locum tenens jobs, which equates to about 1 in 23 PAs.
Over half of PAs (59%) are under the age of 40 years old.
To obtain a license, PAs must graduate from one of the 300 accredited PA programs in the United States. During training, PA students will complete 2,000 hours of clinical rotations as part of their three-year master's degree program. From there, PAs are required to complete 100 hours of continuing medical education every two years to maintain their certification.
Physician assistants can practice in nearly every area of medicine, from primary care to highly specialized fields, including cardiology, surgery, emergency medicine, and psychiatry.
According to the 2025 AAPA Salary Survey, PAs practice medicine in all specialties, including surgical, primary care, internal medicine subspecialties, and more.
Urban. Nearly 90% of physician assistants practice in metropolitan areas. However, those who practice in rural areas often play a vital role in primary care access, in many cases serving as patients' primary care providers.
Physician assistants practice in nearly every type of clinical environment, though most PAs provide care in outpatient settings.
The 2025 AAPA Salary Survey shows that a majority of PAs practice in an outpatient office or clinic.
The short answer is that it depends on the state. While a growing number of states are modernizing their regulations, most do not explicitly use the term "independent practice." Instead, they outline levels of oversight or collaboration, such as whether a physician must review charts, be available for consultation, or provide formal delegation.
In recent years, many states have shifted toward models that allow healthcare organizations and care teams to define these relationships based on patient needs and provider expertise. To clarify these variations, the American Academy of Physician Associates (AAPA) developed a four-tier framework that categorizes each state's regulatory environment for PAs as optimal, advanced, moderate, or reduced.
Lawmakers across the country are steadily updating PA practice laws to reflect the realities of modern care delivery. While most states stop short of formally defining "independent practice," the overall trend is toward models that prioritize collaboration and team-based decision-making over prescriptive supervision. As of July 2025, the states with optimal PA practice include Iowa, Montana, New Hampshire, North Dakota, Utah, and Wyoming, according to the AAPA.
The PA Licensure Compact is an interstate agreement that will allow PAs licensed in one compact state to obtain practice privileges in other compact states more easily. Although it is not yet operational, once implemented, it will streamline the licensing process for PAs, reduce delays, and make it easier for PAs to provide care across state lines, including through telemedicine.
