Roughly 55-60% of DO's match to allopathic residencies(Sourde Insider's guide to Med school). Depending on how competitive the residency a DO student may have to take the USMLE and Comflex(ER, Ortho, Surgery). If you do the military all studentts DO and MD get ACGME training(MD) but all the military training is recognized by the AOA. Go to the AOA web site and look at the match info. Basically as a DO you can apply for both allopathic and osteopathic residencies, but if you match to a DO program you are blocked from allopathic. The same goes for allopathic students except the reverse. THe NRMP just started this last year. However, alot of DO's just apply to allopathic programs becuase they tend to be better funded. It doesn't matter which resideny route you take just choose a good program whether allopathic or osteopathic.The key is to be board certified. You want to look at board pass rates, call schedule, # of slots filled and talk to current residents before you choose a residency. --Good Luck!!
