The problems are...
1) The chairs and program directors tend to be the older faculty. Do you really want them misinterpreting your scores? Past classes didn't have this problem since 230+ was a 99. I can almost guarantee you that these older faculty (chair, program director, etc.) will not figure it out. The secretary will probably know but that might be it. And at my program, all the younger attendings think it's a percentile too because they follow what the older ones say. The residents are the only ones who know what it is and the ones I talked to know it's being phased out because their Step 3 scores didn't have 2-digit scores.
2. As the first responder mentioned above, many ppl probably do not have their original score report. Therefore, there will be a heavy proportion of applicants who will not be reporting a 2-digit score. That's fewer applicants for programs to figure out the new trend in 2 digit scores from, if that make sense? And again, I doubt the older faculty will figure it out. The residents specifically told me it's the secretary who screens out the applications first before the rest of the faculty even sees them. If the secretary screens it correctly, then I guess it's no problem. But the faculty are only seeing the apps who pass the test score screen. Just something to think about it.
- I see it going like this. You might get the interview and then when the faculty member sits down with you, they take a glance at your score for the first time (it's not like they're going to remember you if they had seen your score at an earlier point) and automatically think less of you since you have an 87. When I first met a retina doc at my program, he asked me what my "percentile" was and I explained to him there wasn't a "percentile" listed. He didn't seem to care what I said and then lost interest in me lol. And he was 40 at most.
3. I know that Sfmatch pdf says to send the entire score report if you can, but why? Even though it asks for the 2nd page if you have it, that actually is a bad idea because the NBME wrote specifically at the top that those bar graphs cannot be compared from test to test. However, if you include that, ppl will try compare those pages from test to test anyway.
I just don't know if it's worth the risk. Just pay the extra $65 for a new score report and you won't have to worry about anything. The above have been my experiences and nothing positive has come out of them knowing my 2-digit score. The only reason I was going to report it was because I thought I'd be the only one not to report it and therefore look suspicious. But now that I know that all new score reports will not have it, I don't think that'll be an issue anymore since tons of applicants won't have it. Chances are there are more ppl out there who didn't save their original score report than ones who did.
