The first year of training after medical school is called internship, or more commonly it is called first year of residency or PGY-1 (PostGraduate Year-1). The following years are called PGY-2, PGY-3, etc. The training that is done after a residency (in a subspecialty) is usually called a fellowship. Much of what you will learn in your chosen specialty will be learned in your residency. It's hard to believe that, after 12 years of school, 4 years of college and 4 years of medical school, there is still so much to learn.
