Well, the more I read about CogAT, the less I like it. But I guess the schools have to use something as a screening device. However, I am sure it is underidentifying kids, at least in the 1st grade, for further testing. It is true that this was the first "bubble" test DD ever took. And that is likely the case for the other kids in her class as well.
Cricket2: My DD is in a "high performing" school. For instance, the third-grade Iowa Test average score was 90th percentile for math. That would put a huge swath of children eligible for gifted services if the school only used achievement scores (about 1/2). Iowa test scores above 90th percentile gets kids flagged for more testing, as does CogAT above 96th. The kids must also have creativity and motivation assessment scores above the 90th. Somehow the mixture of these measures brings down the number of kids eligible for services.
