How did they know he did a practice test and what test was it? The CogAT website specifically says that kids should be prepped "to level the playing field", and has resources for teachers to prep their students. DD's teacher never did this. If I had known, I would have prepped DD and we could have avoided disastrous results where she couldn't handle the timing aspect and left half of it blank. Her CogAT score was approx. 20 points lower than her FSIQ and 30+ points lower than her GAI on the WISC. So these school ability tests are not always accurate (or even close to being accurate) to representing a child's ability. I don't blame parents for prepping unless they are trying to get a child who is not gifted into gifted programming. That being said, it depends on the test.
