Just because a health care career has the word “assistant” in its job title, it doesn’t necessarily mean your education will be less strenuous or a less of a commitment to time and effort than other roles—or that your duties will be confined to that of an aide and helper. A good example of two health care careers that could not be more different—but might be confusing due to assistant being in the title—are Medical Assistant and Physician Assistant.

Short and sweet, a medical assistant is more of an entry- to-mid level career while as a physician assistant you will assist and perform advanced duties with a practicing physician.

So, while these two in-demand health care professions sound an awful lot alike, they actually share very little in common when it comes to day-to-day tasks, education requirements, and salary. There are vastly different time and commitment levels needed for you to earn your degree, and the job duties and expertise required are also at opposite ends of the spectrum.

Medical assistants handle a wide variety of entry-level administrative and clinical tasks, whereas physician assistants are licensed health care providers who diagnose and treat patients under the supervision of a physician.

If you’re just entering the health care field, you’ll want to consider a medical assistant career. If you’ve been in the field, have your bachelor’s degree, and are looking to move up the ladder, earning your master’s degree and pursuing your national certification from an accredited PA training program may be the course for you.

Main Differences

Here are all of the key differences for both careers side-by-side:

Job Duties

Medical Assistant

  • Perform administrative tasks, such as updating medical records and arranging for lab services, and clinical duties, such as taking medical histories and recording vital signs.

Physician Assistant

  • Practice medicine under a physician’s supervision, often serving as the principal health care provider in rural or inner-city clinics.


Medical Assistant

  • Many medical assistants start out with a certificate, which usually takes about one year to complete, or an associate’s degree, which typically takes two years.

Physician Assistant

  • Most physician assistants earn a master’s degree (MA-PA: takes about two years, including classroom study and clinical rotation).
    Other options: bachelor’s degree (BA-PA: usually four years, including two-year PA phase), combined bachelor’s/master’s degree (usually five years), associate’s degree (about two years).

Licensing and Certification

Medical Assistant

  • To become a certified medical assistant, you must graduate from an accredited medical assistant training program and pass a certifying exam. You can work as an MA without being certified, but most employers and some states require certification for MAs do things like draw blood. 

Physician Assistant

  • You must be licensed by a state board to practice as a physician assistant. To be eligible for a PA license, you have to pass a national certifying exam, which requires that you graduate from an accredited physician assistant training program.

Median Annual Salaries
