What State are you in? I have fought this battle too. You need to find the district and (if any) the state's rules on GT Identification. Here in Texas we have entirely unenforceable suggestions on acceptable, recognized, and exemplary standards for Identification, Services, and self-assessment. And, the district defines these also in the district's "board policies" manual which is usually online.
The director of services sounds like an idiot! Sorry! I am trying to find a link to research on individually administered vs group administered abilities/IQ tests, but the validity goes way up on individually administered tests. CogAT is an "abilities" test, and any school teacher can administer it! The WISC-IV is a more complex Intelligence test, with much higher levels of education and training required. It is a better instrument! You can score falsely high on a WISC-IV, but you can score falsely low on the CogAT!!! Keep pressing on. Read the board policy yourself. It is ridiculous that because you have the ability to get better testing done by a better trained professional that they can exclude this! Good Luck!
