Hey there!
Rheumatology is through the match - so fellowship match day is June 20, 2007....
Endocrinology uses ERAS, but it does not use the match - so each program had rolling admissions. "Officially" programs were not supposed to make offers until March 1st - however, few programs hold to that. Most programs already made offers from Jan-Mar. I would contact each endo program to be sure of your status....but for endo, this is pretty late in the game (unless they had someone back out, last-minute).
Good luck!
