Ok, while the emphasized text is at odds with your thread title, from what I understand so far you don't care much about the actual practice of medicine, but instead you have a serious issue with people not understanding survey questions which results in poor rating of an institution. My take on this is that I simply don't believe the story you've presented. From what I see it's just as likely, if not even more likely that the poor rating is actually a true reflection of these people's perception.
Obviously you've been to medical school and I haven't, but I have friends who have been and I've also seen plenty of international students first hand to know that your generalizations are completely unfounded.
It appears to me you don't really know much about the current tests, although I'd be rather interested in your idea of how and by whom 'stricter guidelines' should be determined and enforced.
Being a non american in US I have taken various tests and they actually are well beyond spelling few choice words. Incidentally my performance on that 'words' test was pathetic, I was in the bottom 15%. That didn't matter much though, apparently a phone interview was enough to alleviate whatever concerns had arisen from that one score. I suppose I may have gotten the interview because on another test I had a pretty standard score, so given that they wanted me based on my other qualifications it's a matter of figuring which was the representative one.
And, yes I agree that some admissions may be driven by administrators, but I don't think the medical school ones are such. At least not at the top schools. I know this from my friends who went to interview there and their interviews were with faculty, not with administrators.
