Therefore, based on the time of year, the basic types of internships are semester internships, quarterly internships, summer internships, fall internships, spring internships, and holiday or winter internships (i.e. over a winter break). Industry.
Combining the average ~6.5 years of PhD training and 4-5 years of postdoctoral research means that it takes approximately 10 years before a person with a biomedical PhD is ready to begin his or her first or post-training job, and even longer if he or she chooses the academic tenure-track research path.
Internship, Residency and Fellowship. As I discussed above, Residency is a 3+ year training program in a medical specialty. 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.
