How Long Does It Take to Become a Neurosurgeon?

College and medical school take the same 8 years in every specialty, so the difference is all in residency. A general surgeon finishes 2 years sooner, and the surgeon timeline covers that 5-year route. The full list of residency lengths puts every specialty side by side.

The American Board of Neurological Surgery (ABNS) certifies neurosurgeons, and its training requirements spell out what a residency has to contain before you can take its exams:

• Total time: 84 months of neurosurgical residency in ACGME-accredited programs.
• Core clinical work: 54 of those months in core clinical neurosurgery.
• Electives: 30 months in areas such as neuropathology, neuroradiology and research.
• Chief year: 12 months as chief resident during the last two years (PGY-6 or PGY-7).
• Other blocks: 3 months of surgical critical care, 3 months of basic neuroscience within the first 18 months, and at least 6 months of structured education in general patient care.
• Staying put: At least 21 months in one program.

The 54 core months and 30 elective months add up to the 84. So more than a third of residency (30 of 84 months, or about 36 percent) is set aside for electives, and research is one of the options the ABNS names.

There's also a written exam in the middle. The ABNS Primary Examination is a 375-question multiple-choice test, given every March at most US programs, and since July 1, 2023 you have to pass it for credit before you start your chief year.

Programs arrange the 84 months in their own way. Washington University in St. Louis publishes its year-by-year plan, which makes a useful example:

1. PGY-1: A neurosurgery internship. Three months cover the neurology the ABNS requires, and the other nine rotate through neurosurgery, the surgical ICU, otolaryngology, stroke and neurocritical care.
2. PGY-2 and PGY-3: Junior residency on the adult services, with 24-hour call, plus time at the children's hospital.
3. PGY-4: Senior residency, including four months running the pediatric neurosurgery service.
4. PGY-5 and PGY-6: Mostly in the research lab, including six months as a senior registrar at a hospital in Dublin, Ireland.
5. PGY-7: Chief residency, where you're the primary physician for the adult services and perform complex, high-risk operations, often independently.

In that program, 18 months are protected research time, which is about a fifth of the 84 (18 divided by 84 is 21 percent).

Neurosurgery has few seats, and they all fill. In the NRMP's 2026 Advance Data Tables, 121 programs offered 280 first-year positions and filled all 280. Across every specialty, the PGY-1 fill rate was 93.3 percent.

US MD seniors took 243 of the 280 spots. The DO share is small: 9 positions, or 3.2 percent. DOs can still become board-certified neurosurgeons, though. The ABNS says DOs who finish 84 months in an ACGME-accredited program are eligible "through the same process as allopathic physicians." If you're deciding between the two degrees now, the MD vs DO comparison covers how each does in the Match.

Filling every seat doesn't mean every applicant gets one. The NRMP's Charting Outcomes report for 2024 counted 297 US MD seniors whose preferred specialty was neurosurgery. Of those, 204 matched and 93 didn't, a match rate of 68.7 percent, the low end of the range in the report. The same report found that neurosurgery had the highest percentage of matched seniors from the medical schools with the most NIH research funding.

Finishing residency makes you eligible to practice as a neurosurgeon, and plenty keep training anyway. A 2022 study in World Neurosurgery looked at 1,691 academic neurosurgeons in the US and found that 79.13 percent reported fellowship training. The most common choices were:

• Spine: 16.04 percent
• Pediatrics: 11.18 percent
• Cerebrovascular: 9.46 percent

The authors also found that spine, neuroradiology and endovascular fellowships have grown more popular over time. The study only counted neurosurgeons at academic centers, so the rate among neurosurgeons in private practice may be different.

Fellowships are short compared with the residency. Columbia Neurosurgery offers a one-year spine fellowship and a two-year endovascular fellowship. At Johns Hopkins, the endovascular fellowship is 12 months following a preliminary year. The fellowship explainer covers how fellowships work across other specialties.

An estimate, for a student who starts college at 18 and takes no gap years: you'd finish medical school at 26 and neurosurgery residency at 33. A one-year spine fellowship ends at 34, and a two-year endovascular fellowship ends at 35. Each gap year before medical school adds one to every one of those ages.

Residents are paid a salary, but it's a trainee's salary, so in this example the full neurosurgeon's paycheck doesn't start until about 33 at the earliest.

The payoff for the long training is the highest average pay in medicine. Doximity's 2026 Physician Compensation Report, based on about 23,000 surveys of full-time physicians, puts neurosurgery first at an average of $829,161, as reported by Becker's Hospital Review. Thoracic surgery is second at $749,707, and orthopedic surgery is third at $696,852.

The Bureau of Labor Statistics doesn't list neurosurgeons as their own category. It counts them in "surgeons, all other," a group that had a median wage of $414,010 in May 2025, against $275,930 for all physicians and surgeons. Survey averages run higher than BLS medians, because an average gets pulled up by the top earners. How much doctors make compares both sources across specialties and covers the debt you'd carry into residency.

• How many years is neurosurgery residency? 7, or 84 months, and the intern year is included.
• What's the fastest path after high school? 15 years, with no gap year or fellowship.
• Is neurosurgery the longest residency? Yes. It's the only 7-year specialty on the AMA's list.
• Do most neurosurgeons do a fellowship? Among academic neurosurgeons in one 2022 study, 79.13 percent did.
• Can a DO become a neurosurgeon? Yes. US DO seniors matched into 9 neurosurgery positions in 2026, and the ABNS certifies DOs who train in ACGME programs.
• How competitive is the match? In 2024, 68.7 percent of US MD seniors who preferred neurosurgery matched.

All of this starts with the MCAT^®, which tests the neurons, action potentials and brain anatomy that neurosurgeons operate on. The PurpleCAT concept library breaks the nervous system and the rest of the exam's science into short topics you can study one at a time.
