Yes, residency is the training period that comes immediately after graduating from medical school. It is a supervised, hands-on clinical program where new doctors learn to practice medicine independently, and it typically lasts three to seven years depending on the specialty. Residency is not optional: every state requires at least some postgraduate training before granting a full medical license.
What Residency Actually Involves
Medical school teaches the science of medicine through classrooms, labs, and clinical rotations. Residency is where you apply all of that as a working doctor, treating real patients in hospitals and clinics under the guidance of experienced physicians called attendings. The workload is intense. Residents typically put in 60 to 80 hours per week, and the training functions as a full-time job with a salary, not a continuation of school.
First-year residents (called interns) operate under the closest supervision. An attending physician is often physically present during procedures and key decisions. As residents gain experience and demonstrate competence, they’re granted increasing independence. By the later years, a resident may be managing complex cases and performing procedures with minimal oversight, though an attending is always ultimately responsible for patient care.
How Long Residency Lasts
The length depends entirely on which specialty you choose. Some of the most common durations:
- Internal medicine: 3 years
- Pediatrics: 3 years
- General surgery: 5 years
These are minimums required for board certification eligibility. Some specialties, like neurosurgery, can run seven years. If a physician wants to subspecialize further (for example, becoming a cardiologist after completing internal medicine), they pursue an additional fellowship lasting one to three years after residency.
Why It’s Required
Graduating from medical school earns you an MD or DO degree, but that alone does not allow you to practice medicine independently in any U.S. state. Every state medical board requires at least one year of postgraduate training for a full, unrestricted medical license. Many states require two or three years. In practice, nearly all physicians complete their entire residency program before entering independent practice, because finishing residency is also what makes you eligible for board certification in your specialty.
Board certification, administered through the American Board of Medical Specialties, requires completing three to seven years of accredited residency training plus passing a specialty-specific exam. While board certification is technically voluntary, most hospitals and insurance networks require it for employment and credentialing.
How Residents Get Placed
You don’t simply apply to a residency program and get hired. The process runs through the National Resident Matching Program, commonly called “the Match.” During their final year of medical school, students submit applications to residency programs, interview at multiple sites, and then rank their preferred programs in order. Programs simultaneously rank the applicants they interviewed. A computer algorithm pairs applicants and programs based on both preference lists, and results are released on Match Day, typically in March.
The system is binding. Once matched, both the applicant and the program are committed. This process applies to nearly all residency positions in the United States.
Pay and Work Conditions
Residents earn a salary, though it’s modest relative to the hours worked. The nationwide average for a first-year resident in 2025 is about $68,166. Pay increases modestly with each year of training, and by the eighth year (for those in longer programs or fellowships), averages range from roughly $87,000 to $96,000 depending on the type of institution.
Geography matters too. First-year residents in the Western U.S. average around $77,649, while those in the South average closer to $65,076. The Northeast falls in between at roughly $75,000. Resident pay has been rising, but recent increases of about 2.2% per year have trailed inflation.
Federal regulations cap resident work hours at 80 per week, averaged over a four-week period. Individual shifts can last up to 24 hours, with a minimum of 8 hours of rest between shifts. Residents must get at least one day off per week (averaged over four weeks) and can be on overnight call no more than every third night. These rules were put in place to protect both residents and their patients, though the schedule remains grueling by any standard.
What Comes After Residency
Once you finish residency, you become an attending physician, meaning you practice independently and supervise the next generation of residents. Some physicians go straight into practice at this point. Others choose a fellowship to gain expertise in a narrower subspecialty. A general surgeon might pursue a fellowship in transplant surgery, or an internist might specialize in gastroenterology. Fellowships typically add one to three years of additional training.
The full timeline from starting medical school to independent practice is long. Four years of medical school, three to seven years of residency, and potentially one to three more years of fellowship means most physicians don’t begin practicing independently until their early to mid-thirties.
