If they need all three, I can see that bringing down the numbers. Our schools need two eligible scores. These can come from the CogAT (ability), achievement, parent or teacher assessment of behavioral characteristics, creativity scales, leadership scales and maybe a few other things. Any two will do it.
I, too, believe that the CogAT is underidentifying gifted kids, but I also believe that it is overidentifying non-gifted kids as gifted the same way achievement scores can. I guess what I am saying is that I generally don't think that it is a valid test of giftedness.
