My understanding is that most programs use step I scores as a cutoff. In other words, they won't differentiate between applicants who scored 245 versus 260 if their cutoff is 240. I would say that if you score 240+, you will be safe in terms of cutoffs for just about all specialties. A radiology prof just told us all today that once the secretary of the PD decides who gets interviews by looking at board scores, school, grades, etc; your interview makes or breaks your application. That's not to say other things don't matter because they do because a lot of times, the interview is the first time that your interviewer is even looking at your application and probably will be the only time that he or she will read your application carefully. So if you have outstanding research experience and the interviewer likes that, that should be reflected in his or her evaluation of you. Remember that faculty members are looking for residents who they would enjoy being around and wouldn't mind working with above everything else because a bad resident can make other residents and faculty members lives miserable even if he or she scored 270 on their step I.
