Residents are doctors who have graduated from medical school and are completing hands-on training in a specific specialty before practicing independently. They hold medical degrees and are licensed physicians, but they work under the supervision of more experienced doctors called attending physicians. If you’ve been treated at a hospital, especially a teaching hospital, a resident was likely involved in your care.
Where Residents Fit in the Hospital Hierarchy
Hospitals, particularly those affiliated with universities, have a clear chain of training levels. Understanding who’s who can help you make sense of the team caring for you.
Medical students are still in school, typically in their third or fourth year of a four-year program. They shadow doctors and assist with basic tasks, but they don’t make decisions about your care.
Interns are first-year residents. They’ve earned their M.D. but are brand new to clinical practice. They traditionally wear shorter white coats and can only practice under supervision. You’ll sometimes hear them called “PGY-1s,” short for postgraduate year one.
Residents are in their second year of training or beyond. They’ve completed their intern year and have progressively more responsibility and independence. Depending on their specialty, they may be anywhere from their second to seventh year of postgraduate training.
Attending physicians have finished all their training and bear ultimate responsibility for patient care. They supervise residents, make final treatment decisions, and often teach the doctors-in-training working alongside them.
What Residents Actually Do
Residents are deeply involved in day-to-day patient care. Their responsibilities include taking your medical history, performing physical exams, developing treatment plans, ordering tests and medications, writing prescriptions, performing procedures, and assisting in surgery. They also do rounds, which means visiting each patient on their service to assess progress and adjust care plans.
Behind the scenes, residents handle a large volume of documentation: admission notes, progress notes, procedure notes, and discharge summaries. They also coordinate your discharge plan, including follow-up appointments and aftercare instructions. In many teaching hospitals, the resident is the person you’ll interact with most frequently, while the attending physician reviews and approves the overall plan.
A resident’s level of autonomy grows each year. A second-year resident might perform a procedure with an attending watching closely, while a senior resident in their fifth or sixth year might lead a surgery with the attending available as backup. This graduated independence is a core part of the training model.
How Long Residency Lasts
The length of residency depends entirely on the specialty. Primary care fields tend to be shorter, while surgical specialties take considerably longer.
- Three years: Internal medicine, pediatrics, medical genetics
- Four to five years: General surgery, obstetrics and gynecology, emergency medicine, psychiatry
- Five to seven years: Orthopedic surgery, interventional radiology, thoracic surgery
- Seven years: Neurological surgery
After completing residency, some doctors pursue a fellowship, which is an additional one to three years of training in a narrower subspecialty. A cardiologist, for example, first completes a three-year internal medicine residency, then a three-year cardiology fellowship. Fellowship training represents the highest level of recognized clinical training.
How Doctors Get Placed Into Residency Programs
Most residency positions in the U.S. are filled through the National Resident Matching Program, commonly called “the Match.” Medical students apply to programs, interview, and then submit a ranked list of their preferred hospitals. Programs simultaneously rank their preferred applicants. A mathematical algorithm pairs students with programs based on both sides’ preferences. The research behind this algorithm was the basis for a 2012 Nobel Prize in Economic Sciences.
The process is binding. Once matched, the student commits to that hospital and specialty for the duration of their training.
Work Hours and Schedule
Residency is famously demanding. The Accreditation Council for Graduate Medical Education (ACGME) caps residents at 80 hours of clinical work per week, averaged over four weeks. That cap has been in place since 2003. Residents must also get at least one day off per seven, and they cannot work more than 24 consecutive hours of scheduled clinical assignments. After a 24-hour shift, they’re required to have at least 14 hours free of clinical work.
In certain specialties, programs can request exceptions allowing up to 88 hours per week. Clinical work done from home, such as reviewing patient records or answering calls, counts toward the 80-hour limit. Even with these regulations, residents routinely work far more than a typical full-time job, and fatigue is a well-recognized challenge during training.
What Residents Earn
Residents are paid a salary, sometimes called a stipend, that is modest relative to their hours and education level. According to a 2025 survey from the Association of American Medical Colleges, average salaries by training year break down as follows:
- Year 1 (intern): $68,166
- Year 2: $70,499
- Year 3: $73,301
- Year 4: $77,593
- Year 5: $81,807
- Year 6: $84,744
- Year 7: $89,187
When you account for 80-hour work weeks, a first-year resident’s hourly rate works out to roughly $16 to $17 per hour. Pay increases with each year of training but has consistently trailed inflation in recent years, according to the American Medical Association. Once residency ends and a physician enters independent practice, salaries jump significantly, often doubling or tripling depending on the specialty.
Board Certification After Residency
Completing residency doesn’t automatically make a doctor board certified. During their final year of training, residents can apply to take a specialty certification exam administered by one of the member boards of the American Board of Medical Specialties. After finishing training but before passing the exam, a doctor is considered “board eligible.” They typically have three to seven years to take and pass the exam, depending on the specialty. Board certification signals that a physician has met a recognized standard of expertise in their field, and most hospitals and insurance networks require it.
