If they historically take DOs then I would say no usmle needed. You can check to see in they used to me AOA and then they definitely don’t need it. I’m applying family med, Comlex only and I have not had any issues hitting the 15 interviews I wanted. I really don’t think it’s nneeded unless you want to go some big academic center, where in some Cases just being a DO is going to be a no. Which FYI according to the merger no programs can legally require USMLE they can only “highly encourage“ it. Not that ever seems to matter 🤷♀️
