Competitiveness in medical residencies is typically determined by the percentage of unmatched US MD seniors and their mean Step 2 CK scores. Medical residencies can also be ranked by research, by the fewest available spots, and by lifestyle ranking, including work-life balance within that specialty. High unmatched rates in popular fields suggest that too many qualified doctors are left in preliminary years because residency programs aren't growing at the same rate as interest in that field grows. We considered all these factors to compile a list of the most competitive medical residencies.

1. Neurologic Surgery

With the highest unmatched rate (31%) and most research involved (37 items per student), neurologic surgery (neurosurgery) may be the most competitive medical residency — not just because it's hard to get into, but the barrier to entry is also statistically the most grueling. Neurosurgery training is the longest, at 7 years, and because the training is so long and expensive, programs are highly selective.

Matched neurosurgery applicants average 25-37 research products: publications, presentations, or abstracts. Plus, a significant percentage of successful applicants also hold dual degrees (MD-PhD). Neurosurgery leaves nearly 1 in 3 highly qualified applicants without a job come Match Day. The attrition rate is so high that programs may favor nontraditional students, those with high-performing ex-military backgrounds, professional athletes, or career changers.

"The Ascension St. Vincent Neurological Surgery Residency Program was built on a simple yet powerful principle: World-class neurosurgeons are created through intentional mentorship and exceptional clinical training," says Richard B. Rodgers, MD, program director at Ascension St. Vincent Neurological Surgery Residency Program at Goodman Campbell Brain and Spine in Carmel, Indiana.

"A comprehensive allied health team optimizes all aspects of patient care and supports faculty –– ensuring residents are here to learn and grow, not to 'work.'" Although a small program, we offer a strong research infrastructure supporting academic productivity and innovation alongside robust case volumes across all subspecialty areas. We welcomed our first two residents in 2025 and look forward to future applicants who are inspired by our culture of mentorship, excellence, and intentional growth."

2. Dermatology

While neurosurgery often ranks highest in unmatched rates, dermatology frequently ranks among the highest for Step 2 CK scores. Derm has a reputation for being the happiest specialty. Dermatologists work "banker's hours" and are rarely called in for an emergency, so the specialty is consistently ranked high for work-life balance.

Dermatology is also the only specialty that bridges the gap between essential medicine and the cosmetic boom — a $500 billion global aesthetics market — allowing physicians to run lucrative private practices that aren't dependent on insurance reimbursements. Dermatology has fewer spots available, around 550-600 nationwide. This means there are 1.5 applicants for every spot, leaving perfect candidates unmatched each year (18%).

The rank between dermatology and neurosurgery can easily flip depending on which metric you give more credence to –– the higher unmatched rate goes to neurosurgery, but dermatology has higher average board scores, so derm applicants are slightly more likely to match than a neurosurgical applicant.

3. Integrated Plastic Surgery

Integrated plastic surgery rounds out the top 3; however, it too can swap places with neurosurgery and dermatology depending on whether you value board scores or research more.

Historically, residents have completed 5 years of general surgery before specializing in plastic surgery, but the "integrated" path consists of 6 years of plastic surgery training. With only 90-100 programs nationwide and 220-250 available spots, two applicants vie for each spot, resulting in an unmatched rate of 26%-30%.

According to the latest National Residency Matching Program (NRMP) Charting Outcomes, applicants need a triple threat resume: an average 256-258 Step 2 CK score, 25-28 research products, and the cost of away rotations (in-person "auditioning" at hospitals), which is mandatory in the field and costs applicants about $10,000 per applicant cycle.

4. Orthopedic Surgery

While neurosurgery and plastic surgery are viewed as more academic or artistic, orthopedic surgery is often considered "blue-collar elite" for its massive volume of applicants and the sheer physicality of the field.

Ortho surgery is incredibly popular: For every spot, 1.6 applicants competed according to the 2025 Match results, leaving 25%-28% unmatched. Ortho is also DO-friendly — osteopathic students have a strong foothold in the field despite a match rate around 55%-60%.

Matched applicants average 23.8 research products, a significant increase from 2 years ago since Step 1 went to a pass/fail system. And because ortho programs are physically demanding, "audition rotations" are crucial to getting matched. Applicants spend 2-3 months away at hospitals proving their surgical stamina and personality fit for a 5-year residency.

5. Otolaryngology

Otolaryngology (ENT) sits firmly in the middle of the rankings as a niche surgical specialty, offering intricate surgical opportunities coupled with a comfortable lifestyle and an exclusive culture.

ENT typically offers about 350-400 spots nationwide compared to 800 for ortho surgery. In 2025, the unmatched rate for seniors was 25%-28%. Because of so few spots, programs use board scores as their filter, with matched applicants averaging a 256 Step 2 CK score. Twenty research products are typical for applicants.

Applicants are also expected to complete audition rotations (subinternships) at two or three hospitals, where personality fit is crucial due to working on very small teams. ENT also has fewer middle-of-the-night emergencies and a home-for-dinner reputation that attracts applicants for its work-life balance. Program signaling (telling a program it is a top choice) is also a must for being matched.

6. Ophthalmology

Ophthalmology earns its spot mid-list due to its different match system, which often masks its true difficulty on standard residency lists. Unlike the other specialties in the competitive rankings, Ophthalmology uses the San Francisco (SF) Match, where the Match results are released in January, months before Match Day. This forces applicants to commit to their specialty earlier in their fourth year.

For 2025, the Match Rate for US MD seniors was 75%; 1 in 3 were left unmatched. And because the Match system is different, it's not easy to pivot later to a backup specialty for the NRMP Match if applicants aren't matched in ophthalmology. In the 2025-2026 match cycle, the average Step 2 CK scores were 258, the highest average of any specialty. Matched applicants also average 7-11 research products, since programs value fewer ophthalmology-specific research products over many general research items.

Because the specialty is known for the "cataract effect" — taking a legally blind patient and restoring their vision to 20/20 with a 15-minute procedure that has a high success rate — ophthalmology offers incredible job satisfaction.

7. Interventional Radiology

Often described as "surgery through a pinhole," interventional radiology now allows students to match directly into a 6-year program rather than first completing a diagnostic radiology residency and fellowship, as was necessary a few years ago. Because of its relative newness, the number of available spots is low: about 170-210 nationwide. The unmatched rate for US MD seniors hovers around 18%; however, it is much lower for other applicants, including DOs and international medical graduates.

While interventional radiologists do take call (unlike, for example, dermatologists), their workflow is efficient, with mostly daytime surgeries that do not last as long as the 12-hour cases seen in general surgery. The specialty attracts high-scoring, data-driven students because of its tech-heavy focus. Matched interventional radiology applicants scored 253-255 on Step 2 CK in 2025-2026 and had an average of 15.8 research products.

The specialty's focus on pinhole surgery is advantageous — procedures involve smaller incisions, less anesthesia, and faster recovery times. Plus, hospital administrators love the specialty because patients can be moved out of expensive ICU beds and into recovery more quickly. These factors have led to a job market boom in the specialty, with starting salaries rivaling those of surgeons at $500,000-$600,000 annually.

8. Anesthesiology

Historically, anesthesiology was considered a safe choice for students looking for a good lifestyle; however, in the last few match cycles, the specialty's popularity has surged, leaving hundreds of well-qualified US MDs unmatched.

Due to a national shortage of anesthesiologists, starting salaries have ballooned to $450,000-$550,000. And unlike surgery, the specialty works in shift-based models: When your shift is over, another anesthesiologist steps in. This controlled setting may be the driver of the current surge in the specialty.

In 2023, a Step 2 CK score of 240 was safe, but in 2026, matched US MD seniors averaged a score of 252. Also, if applicants don't signal, their likelihood of getting matched is just 5%, leaving the Match little more than a high-stakes gamble.

The specialty attracts adrenaline junkies who enjoy pharmacology and physics, and it also includes the 99/1 rule: 99% boredom and 1% sheer terror. Anesthesiologists must stay focused and alert through long hours of surgery but then act with lightning speed when a patient's blood pressure plummets or airway collapses.

"My residency at Oklahoma State University gave me something most programs structurally can't. The program takes three residents per class. That means you're not lost in a crowd," says Jason Schroder, MD, medical director and co-founder of Craft Body Scan in Tulsa, Oklahoma. "Attending physicians get to know your cases, your spaces between, and your progress in a way that larger programs don't allow, and the anesthesiology program puts complex cardiac, vascular, and obstetric cases in front of residents early, not as a reward for seniority. That early exposure to acuity is what built the diagnostic instincts that I carry with me."

9. Radiation Oncology

Radiation oncology was once among the top 3 competitive specialties, along with plastic surgery and dermatology, but interest has since cooled, likely due to future job markets, the advent of AI, and Medicare reimbursement changes slated for 2026.

The specialty remains statistically competitive because it has the fewest spots of almost any specialty (often just a dozen or so). Plus, the academic barrier is still extremely high, with average Step 2 CK scores of 252 for the 2025-2026 cycle. Programs still want high scores and heavy research (at least 15 items), but the odds of getting into a big-name program, such as Harvard or MD Anderson Cancer Center, are much higher than in other fields.

10. Diagnostic Radiology

Diagnostic radiology has seen a massive surge in competitiveness as students move from frontline thinking to a "doctor's doctor" philosophy, in which medical detectives provide the definitive data that other doctors need.

The unmatched rate in diagnostic radiology has climbed to 15% for the last Match cycle, and in 2025, matched applicants averaged a Step 2 CK score of 256 — the same as in orthopedics and ENT.

Contrary to fears that AI could replace radiologists, the technology has become a super-tool that has revitalized interest in the field. Diagnostic radiology is also seeing a surge because it offers the possibility of remote work — you can read scans in your pajamas at your home office and still earn a salary of $500,000 or more. In 2025, it was very difficult to match to a top-tier city without a Step score of at least 255.
