You should also check this past year's match lists on the osteopathic forum. There were DO's accepted to programs that had never interviewed DO's in the past. It is too broad to say that all programs accept and interview DO's. You should apply to programs that have taken DO's in the past and also to a few programs you are really interested in that have never taken DO's. It is a huge waste of money to apply to a lot of programs that have never interviewed or taken DO's. More of the Texas programs took DO's this year, and Iowa took its first DO ever. Just look at the osteopathic forum match list.
