Since I’ve been in training, I’ve often had questions about the various training paths that exist. While sources exist with this information, I have found many of them to be incomplete. I created a table listing lengths for residencies and fellowships available through ACGME. I initially started by only creating a table for my specialty, but eventually decided to cover all fields of medicine one can pursue. While this list is not comprehensive, I feel it is very close. As there are countless non accredited programs and various overlaps amongst subspecialty training available through multiple pathways, it is likely impossible to get it completely accurate. But, I hope medical students, residents and other aspiring physicians may find this useful as it took a lot of time to make.
