The Timeline: 13 to 15 Years After High School
Becoming a general surgeon takes 13 to 15 years after you finish high school. This includes four years of undergraduate study, four years of medical school, and five to seven years of surgical residency training. The exact length depends on whether you pursue additional fellowship training and whether you complete your residency in the standard timeframe or extend it.
The path is long because surgery requires both broad medical knowledge and thousands of hours of supervised practice. You cannot skip steps or compress the timeline significantly — medical licensing boards and residency programs have set requirements that exist for patient safety.
Most surgeons finish their residency between ages 30 and 35, though some start earlier if they complete undergraduate work quickly or later if they take time between steps.
Key Takeaways
- Medical school and residency together account for nine to eleven years, and both have fixed lengths you cannot shorten.
- Your four-year undergraduate degree can be in any field, but you must complete specific science courses that medical schools require.
- Residency is where you actually learn surgery — it is paid work, not additional schooling, and you earn a salary while training.
- Board certification requires passing written and oral exams after residency, which adds several months to a year to the timeline.
- Some surgeons add one to three years for fellowship training in a specialty like trauma, vascular, or pediatric surgery.
Undergraduate Degree: Four Years
Your first four years are a standard bachelor's degree. You can major in any subject — biology, chemistry, engineering, even English — as long as you complete the science courses that medical schools require. These courses are called prerequisites and typically include biology, chemistry, organic chemistry, biochemistry, physics, and sometimes anatomy or physiology.
Most students take these courses during their first two years and use the remaining time for their major and electives. Some students finish prerequisites faster by taking summer courses or by placing out of introductory classes. Others take longer if they change majors or retake courses to improve their grade.
Medical schools care about your grades in science courses more than your overall GPA, so struggling in chemistry or biology can delay your process by a year or more if you need to retake the course.
Medical School: Four Years
Medical school is four years of classroom and clinical training. The first two years are mostly lectures, labs, and exams covering anatomy, physiology, pharmacology, pathology, and other foundational subjects. The second two years shift to clinical rotations, where you work alongside doctors in hospitals and clinics, seeing patients and learning how medicine is actually practiced.
You cannot compress medical school or attend part-time. All accredited medical schools in the United States follow the same four-year structure. Some schools offer a three-year accelerated program, but these are rare and highly competitive.
During your fourth year, you explore to residency programs. This process takes several months — you submit applications in the fall, interview at programs in winter, and match to a program in spring. If you do not match to a residency position, you must reapply the following year, which delays your start by 12 months.
Surgical Residency: Five to Seven Years
Residency is where you become a surgeon. A general surgery residency lasts five years in most programs, though some are structured as six or seven years. You work in a hospital under the supervision of senior surgeons, gradually taking on more responsibility as you progress through the years.
In your first year (called PGY-1, or postgraduate year one), you rotate through different surgical services — trauma, vascular, colorectal, orthopedic — to learn the basics. By your third and fourth years, you are performing major operations under supervision. By your fifth year, you are managing complex cases and teaching junior residents.
Residency is full-time work with on-call shifts, often 60 to 80 hours per week. You are paid a salary — starting around $65,000 to $75,000 per year and increasing each year — so you are earning while you train. You cannot extend residency to part-time or take significant time off without delaying your graduation date.
Some residents take a research year during their residency, which extends the total time by one year. This is optional and more common if you plan to pursue an academic career or a competitive fellowship.
Board Certification: Several Months to One Year
After you finish residency, you must pass the American Board of Surgery exams to become board-certified. This is not required to practice surgery, but most hospitals require it and patients expect it.
The process has two parts: a written exam (called the written board exam or may have access to exam) and an oral exam (called the oral board exam or certifying exam). You can take the written exam during your final year of residency or after you finish. The oral exam comes later, usually one to two years after you finish residency.
Most surgeons pass both exams on their first attempt, but if you fail, you must wait and retake the exam, which adds several months to a year to the timeline.
Fellowship Training: One to Three Additional Years (Optional)
After residency and board certification, some surgeons pursue fellowship training in a surgical specialty. Common fellowships include trauma surgery, vascular surgery, surgical oncology, pediatric surgery, and colorectal surgery. A fellowship typically lasts one to three years depending on the specialty.
Fellowship is optional — you can practice as a general surgeon without it. But if you want to specialize or work at an academic medical center, a fellowship is often expected. Pursuing a fellowship adds one to three years to your total timeline.
Fellowship positions are competitive and you explore during your final year of residency, similar to how you applied to residency during medical school.
What Delays the Timeline
Several things can extend the path beyond 13 to 15 years. Retaking the Medical College Admission Test (MCAT) before explore to medical school can add one to two years if you do not score high enough on your first attempt. Not matching to a residency program means reapplying the next year, which delays your start by 12 months.
Taking a gap year between undergraduate and medical school, or between medical school and residency, adds one year each. Some students do this intentionally to work, conduct research, or improve their process. Failing board exams and retaking them adds several months.
Pursuing a research year during residency adds one year. Taking time off for personal reasons, illness, or family needs extends your timeline by however long you are away.
Frequently Asked Questions
Can you become a surgeon faster than 13 years?
No. Medical school is four years, residency is five years minimum, and you cannot shorten either one. You can save time by completing your undergraduate prerequisites quickly and by not taking gap years, but the total is still at least 13 years from high school graduation.
Do you have to do a fellowship after residency?
No. You can practice as a general surgeon after residency and board certification without additional fellowship training. A fellowship is required only if you want to specialize in a particular area of surgery or if a specific job requires it.
How much does it cost to become a general surgeon?
Medical school costs vary widely — private schools can cost $200,000 to $300,000 total, while public schools are often $100,000 to $200,000. Many surgeons graduate with student loan debt. Residency is paid, so you earn a salary during those years and do not incur additional education costs.
Can you work while going through medical school and residency?
Medical school is full-time and does not allow outside work. Residency is also full-time with on-call shifts, so a second job is not realistic. Some residents do small amounts of consulting or teaching, but it is limited.
What if you don't pass the board exams?
You can retake the exam. Most surgeons pass on the first attempt. If you fail, you wait several months and retake it. Failing does not prevent you from practicing surgery, but board certification is expected by most employers and hospitals.
