A resident is a doctor who has graduated from medical school and is now training in a specific specialty, like internal medicine or surgery, by treating patients under supervision at a hospital. Residents hold medical degrees and make real clinical decisions, but they aren’t yet fully independent physicians. Think of residency as the bridge between medical school and practicing medicine on your own.
What Residents Actually Do All Day
Residents are hands-on doctors. They see patients, order tests, write prescriptions, perform procedures, and coordinate care across teams. But the breakdown of how they spend their time might surprise you. A study tracking internal medicine residents found that first-year residents spent about 38% of their day on the computer, 21% discussing patients with other doctors, and only 18% of their time physically at a patient’s bedside. The rest went to administrative work: faxing, printing, making phone calls to nurses, pharmacies, and family members.
First-year residents averaged 12.5-hour days while managing about six patients. By their third year, they were overseeing roughly 12 patients but actually working about 1.5 hours less per day. That shift reflects a key part of residency: as trainees gain experience, they spend less time on data entry and more time leading discussions about patient care and supervising junior residents.
Intern vs. Resident
You’ll sometimes hear the word “intern” used in hospitals. An intern is simply a first-year resident. The intern year focuses less on deep specialty training and more on building a foundation: learning how to coordinate a patient’s care, managing administrative duties, and adjusting to the responsibility of treating real patients rather than studying them in a classroom. After that first year, the title shifts to “resident” for the remaining training years, though technically all of them, including interns, fall under the resident umbrella.
How Residents Fit Into the Hospital Hierarchy
Every patient in a hospital has an attending physician who is ultimately responsible for their care. The attending is a fully licensed, board-certified doctor. Residents work under this attending, and the amount of independence they get depends on their experience level.
First-year residents must always be supervised, either directly or with a senior physician immediately available. They can’t make major decisions alone. By their third year, residents may handle routine admissions with only oversight from the attending. Critical decisions, like end-of-life care, always remain with the attending regardless of a resident’s experience. A program director and competency committee formally evaluate each resident’s progress and decide when they’re ready for more independence.
The attending reviews all charts and orders, serving as both a safety net and a teaching resource. If you’re a patient, both the resident and the attending should let you know their roles in your care.
How Long Residency Lasts
Residency length depends entirely on the specialty. Internal medicine and pediatrics each require three years. General surgery takes five. Some specialties fall somewhere in between, and these are minimums for board certification eligibility.
Doctors who want to narrow their focus even further can pursue a fellowship after residency. A fellowship is subspecialty training that builds on the residency foundation. For example, a doctor who completes an internal medicine residency might do a cardiology fellowship to specialize in heart disease. Fellowship represents the highest level of recognized clinical training.
How Doctors Get Placed Into Residency
Most residency positions in the U.S. are filled through a system called “the Match,” run by the National Resident Matching Program. It works like this: medical students apply to programs, interview, and then submit a ranked list of their preferred programs. Programs simultaneously rank the applicants they interviewed. A computer algorithm then pairs applicants with programs based on mutual preference, trying to place each student at their highest-ranked program that also wants them.
If a program prefers a new applicant over someone already tentatively matched there, the earlier applicant gets bumped and the algorithm tries to place them at their next choice. Once every applicant’s list has been processed, the tentative matches become final and binding. Match results are announced on a single day in March each year, and it’s a defining moment in every new doctor’s career.
Work Hours and Conditions
Residency is notoriously demanding. The Accreditation Council for Graduate Medical Education caps residents at 80 hours per week, averaged over four weeks. That includes all clinical duties, educational activities, and even clinical work done from home. Residents cannot work more than 24 continuous hours of scheduled clinical assignments, though up to four additional hours are allowed for handoffs and education (not new patient care responsibilities).
Residents are supposed to get at least eight hours off between scheduled shifts and must have 14 hours free after a 24-hour on-call period. They’re also guaranteed at least one day per week free of clinical work and required education, averaged over four weeks. These limits were put in place because earlier generations of residents routinely worked 100-plus hour weeks, raising serious concerns about patient safety and physician well-being.
Pay During Residency
Residents earn a salary, but it’s modest relative to their hours and training. At UCLA, for example, a first-year resident earns about $93,777 per year as of late 2025. Pay increases incrementally with each training year: a second-year resident makes roughly $96,400, a third-year about $99,600, and so on up through the most senior fellows. When you divide those salaries by 70 or 80 hours of work per week, the effective hourly rate is far lower than what a fully trained physician earns.
Licensing During and After Training
Residents practice under a training permit issued by their state medical board. This permit allows them to treat patients only within the supervised context of their residency program. To earn a full, unrestricted medical license, every state requires at least one year of postgraduate training. Some states require two or three years. More than a dozen states also require residents to pass their full licensing exams before reaching a certain point in training, sometimes before starting their second or third year.
Once a resident completes their program and passes all licensing and board exams, they become an attending physician, free to practice independently, join a medical group, or open their own practice.
