Hello jaggirl47,
I am in a similar situation - except we have already had the WISC-IV test which shows my dd9 to be gifted, and the school district doesn't want to take it into consideration! On the CogAT she scored 97% for quantitative, but 67%(!!) for verbal, which is her strength! The cutoff for HC here (also WA) is 98% on a cognitive test. You wold think her WISC-IV scores would qualify her (percentiles were VCI 99, PRI 99, WMI 99.8, PSI 98, and FSIQ 99.8) but apparently not. In addition, they don't allow appeals.
I need to get my hands on some studies that show weaknesses with the CogAT test. Could you post links to the studies you mentioned, or forward the emails to me? I'll private message you my email address. Thanks in advance!!!
