How Long Does It Take to Become a Dermatologist?

The American Board of Dermatology (ABD) sets the rule: you need "three years of full-time training as a resident in a dermatology residency training program," and "a total of four years of postgraduate training." That's why the AMA's list of residency lengths puts dermatology under "Four years," the same group as anesthesiology, psychiatry and OB-GYN.

College and medical school take the same 8 years for every specialty. The general timeline to becoming a doctor covers those years, including the gap years most applicants now take.

Your first year after medical school isn't spent in dermatology. The ABD says it "must consist of 12 months of clinical training," and it accepts a transitional year, a preliminary year, or a first year of residency in internal medicine, pediatrics, surgery, emergency medicine, family medicine or OB-GYN.

That shapes how you apply. Most dermatology programs offer advanced positions, which start in the PGY-2 year, so you'd also match into a separate 1-year intern position. Of the 585 positions in the three main dermatology tracks in the 2026 Match, 546 were PGY-2 seats. A smaller set of 31 categorical PGY-1 positions, at 15 programs, includes the intern year.

You're paid a resident's salary from the first day of that intern year, so all 4 postgraduate years are salaried.

Very. According to the NRMP's 2026 Advance Data Tables, 156 programs offered 546 PGY-2 dermatology positions and filled 545 of them, a fill rate of 99.8 percent. The 31 categorical PGY-1 positions and the 8 dermatology-internal medicine positions all filled.

Here's who took those seats.

US MD seniors filled 465 of the 584 seats, or 79.6 percent. US DO seniors filled 36, or 6.2 percent. For comparison, DO seniors took 144 of the 1,066 filled PGY-2 diagnostic radiology seats in the same Match, or 13.5 percent, as the radiology timeline shows. If you're weighing MD and DO schools with dermatology in mind, that difference belongs in the comparison.

The applicants who match tend to bring a lot of research. In the NRMP's 2024 Charting Outcomes report, as tallied by MedEdits, 314 US MD seniors who preferred dermatology matched into it and 126 didn't, a match rate of 71.4 percent for that group.

The gap in research output, 27.7 items against 19.0, is larger than the 7-point gap in Step 2 CK scores. Program signals matter too. In the 2024 application cycle, each dermatology applicant could send 3 gold and 25 silver signals, and the median interview rate across 97 programs was 54 percent with a gold signal, 14 percent with a silver one and about 0 percent with none, according to the same MedEdits summary of AAMC and JAAD data. What happens on Match Day explains how the algorithm pairs ranked applicants with programs.

The ABD certifies dermatologists through three exams. A 2026 Cutis article on the dermatology boards and the ABD's exam information page describe them:

1. BASIC Exam. Taken by first-year dermatology residents at their home institution. It "is solely for informational purposes," and no minimum score is required for certification.
2. CORE Exam. Four modules (medical, surgical, pediatric and dermatopathology), each with 75 to 100 multiple-choice questions over 2 hours. Residents become eligible during their second year of dermatology residency, and they can keep attempting unpassed modules after graduation.
3. APPLIED Exam. An 8-hour, 200-question exam taken in person at a testing center, open once you've passed all 4 CORE modules and finished residency. You have 5 years after residency to pass it.

You can practice general dermatology straight out of residency. A fellowship adds a year for a narrower field. Oregon Health and Science University lists three ACGME-accredited dermatology fellowships, each 1 year long:

• Micrographic surgery and dermatologic oncology: Mohs surgery for skin cancer.
• Pediatric dermatology: Skin disease in children.
• Dermatopathology: Diagnosing skin disease from tissue under the microscope.

The fellowship explainer covers how fellowships work in other specialties.

The combined internal medicine and dermatology residency is the other route to 13 years. The ABIM's guidelines set it at 60 months, with at least 10 months of internal medicine in the first year, at least 10 months of dermatology in the second, and an even split across years 3 through 5. In 2026, US MD seniors filled all 8 of its positions.

An estimate, for a student who starts medical school at 22 with no gap year: you'd finish medical school at 26, the intern year at 27 and dermatology residency at 30. A fellowship or the combined track ends at 31. Each gap year, or a year spent reapplying, adds one to each of those ages.

The Bureau of Labor Statistics reports a median annual wage of $328,730 for dermatologists in May 2025, against $275,930 for all physicians and surgeons. That's $52,800 above the overall median, after 1 more year of training than the 11-year minimum for internal medicine or pediatrics. How much doctors make sets that figure beside other specialties and resident stipends.

• How many years of residency is dermatology? 3 years of dermatology after a 1-year intern year, so 4 postgraduate years.
• What's the fastest path? 12 years after high school, with no gap year and no fellowship.
• Can DO graduates become dermatologists? Yes. US DO seniors filled 36 dermatology positions in the 2026 Match.
• Is a fellowship required? No. The three dermatology fellowships are optional and last 1 year each.
• When do you take the boards? BASIC in your first dermatology year, CORE starting in your second, and APPLIED after residency.

The 12-year clock starts with steps you control now: your prerequisites, your MCAT^® and your application. Dermatology leans on immunology and cell biology, which the MCAT^® tests in Bio/Biochem. The PurpleCAT concept library breaks those topics into short pages you can study one at a time.
