You can be boarded in pediatric dermatology in 2 ways:
1) After completing a pediatric intern year (or residency) and a three year derm residency, you only need 1 year of fellowship
2) If you do any other type of internship, you require 2 years of fellowship
Derm surgery is part of every resident's training, but the extent of the surgical experience is different from program to program. For example, residents at Texas Tech, Iowa, Miami, and Florida perform enough Mohs cases as primary surgeon that they can apply for certification by the Mohs Society (but not the more respected Mohs College, which requires a fellowship year...long story...you'll hear more about it when you interview for derm).
