We cross-posted. Our district has used the same 130 cutoff for years. I have a hunch that kids who would have made the cutoff in earlier years are not making the cutoff -- could be that kids who were taking an older IQ test, say, in 2006 were artificially high due to the Flynn effect or there could be some flaw with the new test. Sometimes a bell curve may be forced onto data that is not really normally distributed - I suspect there's some of that, but again, who knows...
