To be a board-certified dermatologist in the United States requires many years of education. One must successfully complete:

  • College, earning a bachelor’s degree.
  • Medical school, becoming a medical doctor (MD) or doctor of osteopathic medicine (DO).
  • Internship, 1 year of required medical training.
  • An accredited dermatology residency program, at least 3 years.

After successfully completing the residency program, one can become a board-certified dermatologist by:

  • Having a license to practice medicine.
  • Passing the exams given by the American Board of Dermatology, the American Osteopathic Association, or the Royal College of Physicians and Surgeons of Canada.
  • Meeting other requirements.

The board exams test the doctor’s knowledge, experience, and skills. All of the above are essential to provide quality patient care in dermatology.
