Is an Intern a Doctor? What They Can and Can’t Do

Yes, a medical intern is a doctor. An intern has graduated from medical school and earned an M.D. or D.O. degree, making them a fully credentialed physician. The key distinction is that interns cannot practice independently. They work under the direct supervision of more senior doctors during their first year of postgraduate training.

What Makes an Intern a Doctor

By the time someone becomes an intern, they’ve completed four years of undergraduate education and four years of medical school. They hold a doctoral degree in medicine. The confusion is understandable, though, because interns look and function differently from the seasoned doctor most people picture. They’re still learning, still supervised, and still years away from practicing on their own.

The formal term for an intern is PGY-1, short for “postgraduate year one.” The Accreditation Council for Graduate Medical Education (ACGME), which oversees residency training in the U.S., doesn’t even use the word “intern” in its official language. It considers all trainees “residents,” with the intern year simply being the first year of residency. In everyday hospital culture, though, “intern” remains the common label for a first-year resident.

What an Intern Can and Cannot Do

Interns examine patients, write orders, perform procedures, and make clinical decisions, but everything they do is checked by a supervising physician. ACGME rules require that PGY-1 residents be “directly supervised” at the start of their training. That means a more experienced doctor must be physically present or immediately available to review their work.

Interns are also not permitted to moonlight, meaning they can’t take extra clinical shifts outside their training program. Most state medical boards issue a limited training permit rather than a full medical license during this period. To qualify for an unrestricted license, a doctor must complete at least one full year of postgraduate training. So while an intern is legally a physician, their authority to practice is tightly restricted to the supervised setting of their residency program.

Where Interns Fit in the Hospital Hierarchy

Teaching hospitals have a clear chain of command. From least to most senior, it runs: intern, resident, fellow, attending physician. The attending is the doctor with ultimate responsibility for a patient’s care and has completed all training. Fellows are doctors pursuing additional specialization after residency. Residents are in their second year of training or beyond. And interns sit at the bottom of the physician ladder, learning the ropes under everyone above them.

Some residency programs also designate a chief resident, a senior trainee who takes on administrative and teaching duties above the other residents but below the program’s leadership. If you’re a patient in a teaching hospital, the intern may be the doctor you interact with most often. But their decisions are reviewed and approved by the resident or attending overseeing your care.

The Intern Year Up Close

The intern year is widely considered the most grueling stage of medical training. ACGME rules cap clinical work at 80 hours per week, averaged over four weeks. Shifts can last up to 24 consecutive hours, with an additional four hours allowed for handoffs and education. That’s a significant improvement over past decades, when 100-plus-hour weeks were routine, but it’s still roughly double a standard full-time job.

First-year residents earn an average salary of about $68,000 per year. Divided across those long hours, the effective hourly pay is modest, especially for someone carrying the six-figure student debt that medical school typically generates. The combination of high responsibility, steep learning curve, long hours, and relatively low pay is why the intern year has a reputation as a trial by fire.

What Happens After the Intern Year

Once doctors finish their intern year, they become eligible for a full, unrestricted medical license. At that point, they could technically practice as a general physician. In reality, the vast majority continue into the remaining years of their residency to specialize. Depending on the specialty, residency lasts two to seven additional years. A surgeon, for example, may train for five or six more years after the intern year, while a family medicine doctor may have only two years left.

After residency, some doctors pursue a fellowship for even more specialized training (pediatric cardiology, for instance, or sports medicine). Others go straight into practice as attending physicians. The intern year is just the first rung, but it is the point at which a medical school graduate becomes, without question, a doctor.

International Equivalents

The word “intern” is used in the U.S. and Australia but not everywhere. In the UK, the equivalent role is called Foundation Year 1, or F1. In Australia, an intern is a PGY-1 doctor with provisional registration who must complete 12 months of supervised training before receiving full registration with the Medical Board of Australia. The structure is similar across countries: a newly graduated doctor works under supervision for at least a year before gaining the authority to practice independently. The titles differ, but the concept is the same.
