If you Google “clinical clerkship” you will find information on everything about the subject. I called ACGME about it and the representative on the phone couldn’t help me answer my question so I had no choice but to research myself. I go to a Caribbean school, and so far it’s doing well; however, it still has a long way till it matches a high-rep school such as Ross Medical University. Therefore, as an American IMG, I have to do my own research. The term “green book” is actually an unofficial term that medical students use. If a hospital is a teaching hospital that offers at least one residency, which is approved by ACGME, then that hospital is “green book” approved. Usually those hospitals will have rotations in Internal Medicine, Family Practice, etc. Now if I’m wrong, please tell me but I’m telling you based on what I’ve read.
