After completing a three- to five-year residency, about 30% of the fully trained physicians elect to pursue additional training to become subspecialists.
Subspecialty training may last an additional one to four years. Usually the focus of subspecialty training is fairly narrow and allows the physician to obtain knowledge and skills needed to perform additional procedures or focus on treating patients with a particular type of problem. Most subspecialties have additional board exams at the end of their training qualifying the physician to be a board-certified subspecialist.
The most common specialties and subspecialties, as well as the years of training required, are listed here. In some cases, more than one specialty training may qualify a physician for fellowship training.
