I am no expert (someone here who is one should reply soon) but I would want to know what this "screening process" was. My DD9, for example, has a high IQ on the WISC, but does not reflect this every year on the Cogat. So, I think that the type of test, how it was administered, etc., matters. In addition, perhaps the tester didn't establish a good rapport, this is part of the screening process, I assume and should be in the report. Also, there could be a 2e issue?
