The Timeline: 14 to 16 Years After High School

Becoming a brain surgeon takes 14 to 16 years of education and training after you finish high school. That breaks down into four years of undergraduate study, four years of medical school, five to seven years of neurosurgery residency, and sometimes one to two additional years of fellowship training in a subspecialty. The exact length depends on whether you pursue extra training and which neurosurgery program accepts you.

The path is long because neurosurgery is one of the most demanding medical specialties. You are learning to operate on the most complex organ in the human body, and mistakes carry severe consequences. Each stage — medical school, residency, and fellowship — has specific requirements you cannot skip or shorten.

Key Takeaways

  • Medical school takes four years, and you must complete it before you can enter a neurosurgery residency program.
  • Neurosurgery residency lasts five to seven years and is where you actually learn to perform brain surgery under supervision.
  • Many neurosurgeons complete an additional one to two years of fellowship training to specialize in a particular type of brain surgery.
  • Your undergraduate grades, Medical College Admission Test (MCAT) score, and performance in medical school determine whether you can match into a competitive neurosurgery program.
  • You earn a salary during residency and fellowship, so the training years are not unpaid.

Undergraduate Education: 4 Years

Your first four years are a standard bachelor's degree at a college or university. You do not have to major in biology or chemistry, but you must complete the pre-medical requirements: one year of biology with lab, one year of chemistry with lab, one year of organic chemistry with lab, one year of physics with lab, and usually one year of biochemistry or another advanced science course. Many schools also require calculus and English.

Medical schools look at your overall grade point average (GPA) in these science courses, your overall GPA across all courses, and your MCAT score. Competitive applicants to medical school typically have a GPA of 3.7 or higher and an MCAT score in the 510 to 520 range, though these numbers vary by school. You take the MCAT during your junior or senior year, usually after completing most of your pre-medical courses.

During these four years, you should also gain experience in a hospital or clinical setting — volunteering, shadowing a doctor, or working as an emergency medical technician (EMT) or medical scribe. Medical schools want to see that you have spent time around medicine and understand what the work involves.

Medical School: 4 Years

Medical school is a four-year program that leads to the degree of Doctor of Medicine (M.D.) or Doctor of Osteopathic Medicine (D.O.). The first two years are mostly classroom and laboratory work: anatomy, physiology, pharmacology, pathology, and other foundational sciences. The second two years are clinical rotations, where you work alongside doctors in hospitals and clinics, seeing patients and learning hands-on skills.

During medical school, you take licensing exams called the United States Medical Licensing Examination (USMLE) steps or the Comprehensive Osteopathic Medical Licensing Examination (COMLEX) steps. You must pass these exams to move forward. Your performance on these exams, your grades, and your clinical evaluations from attending physicians all factor into whether you can match into a neurosurgery residency.

Neurosurgery is one of the most competitive specialties in medicine. To match into a neurosurgery program, you typically need to be in the top tier of your medical school class, score very high on licensing exams, and have strong letters of recommendation from neurosurgeons or senior surgeons who have worked with you.

Neurosurgery Residency: 5 to 7 Years

After medical school, you enter a neurosurgery residency program. This is where you actually learn to perform brain and spine surgery. The program lasts five to seven years, depending on the institution and whether you pursue additional training within the residency.

During residency, you work under the supervision of experienced neurosurgeons. In your early years, you information in surgery, learn anatomy in the operating room, and gradually take on more responsibility. By your final years, you are performing complex surgeries with an attending surgeon present. You also spend time in the clinic seeing patients, reading imaging studies, and learning to diagnose neurological conditions.

Residency is demanding. You work long hours, including nights and weekends on call. You are responsible for patients' care and must be available for emergencies. However, you earn a salary during residency — typically starting around $65,000 to $75,000 per year and increasing each year. The salary varies by program, location, and whether you are at an academic medical center or a private hospital.

Fellowship Training: 1 to 2 Years (Optional)

After residency, many neurosurgeons pursue one to two additional years of fellowship training in a subspecialty. Common fellowships include spine surgery, pediatric neurosurgery, vascular neurosurgery, neuro-oncology (brain tumors), functional neurosurgery, and stereotactic radiosurgery. A fellowship lets you develop informed in a narrower field and often improves your job prospects or earning potential.

Fellowship is optional. You can practice as a general neurosurgeon after residency without additional training. However, some job markets favor surgeons with fellowship training, and some positions at academic medical centers require or prefer it. You earn a salary during fellowship, similar to your final residency years.

Board Certification and Licensure

To practice as a neurosurgeon, you must be licensed in the state where you work. Licensure requires passing the USMLE or COMLEX exams and completing an accredited residency program. After residency, you are may be able to access to take the American Board of Neurological Surgery (ABNS) certification exam. This is a written and oral exam that tests your knowledge and surgical skills.

Board certification is not legally required to practice, but most hospitals require it or require that you be may be able to access to take the exam. Most neurosurgeons complete board certification within one to two years after finishing residency. Once you pass, you are a board-certified neurosurgeon.

Factors That Affect the Timeline

The 14 to 16 year timeline assumes you move through each stage without delays. Some factors can extend the timeline. If you do not match into a neurosurgery residency on your first attempt, you may need to spend a year in a different specialty or in research before reapplying. If you pursue a fellowship, add one to two years. If you take time off for personal reasons, that also extends the timeline.

Conversely, some people finish medical school in three years through accelerated programs, though this is rare and does not shorten the residency requirement. The residency and fellowship years are set by the specialty and cannot be shortened, regardless of how fast you progress.

Frequently Asked Questions

Can you become a brain surgeon faster by going to medical school part-time?

No. Medical school is four years whether you attend full-time or part-time, and most programs do not offer part-time tracks. Residency and fellowship are also fixed lengths set by the specialty board. The timeline cannot be compressed.

Do you have to do a fellowship after neurosurgery residency?

No. You can practice as a general neurosurgeon after completing residency and passing board certification. However, many job positions, especially at academic medical centers, prefer or require fellowship training in a subspecialty. The job market in your region will influence whether fellowship is necessary for the type of work you want.

How much do neurosurgeons earn during training?

Residents earn a salary starting around $65,000 to $75,000 per year in their first year and increasing each year, reaching $80,000 to $100,000 by the final year. Fellowship salaries are similar. These figures vary by program, location, and institution. You also receive benefits like health insurance and malpractice coverage.

What happens if you don't match into a neurosurgery residency?

If you do not match, you can pursue a different medical specialty, take a research year and reapply to neurosurgery, or pursue a transitional year position and try again. Some people who do not match on the first attempt successfully match in subsequent years. Matching is competitive, and not everyone who applies to neurosurgery is accepted.

Is the timeline the same for D.O. and M.D. graduates?

Yes. Both M.D. and D.O. graduates follow the same residency and fellowship timeline. D.O. graduates take the COMLEX exams instead of the USMLE, but the length of training is identical. Both are may be able to access to match into neurosurgery residency programs.
