It's not entirely true to say that none of the firefighters who earned a promotion-level score was a minority; one was Hispanic, while the rest were white.

I agree that it's not fair to throw out the test results for that reason, but doesn't it seem odd to you that almost no minority firefighters scored high enough to earn a promotion? There is a problem there -- whether it's the firefighters themselves not studying enough, or the test being somehow off, something isn't right. I don't see how it's possible that *only* whites (with the exception of the one minority) scored high enough to pass -- statistically, that's not how things work.
