I think they use a grade level ahead. So she was in second grade and taking the third grade test. The other issue was that she had just turned 7 when she took it, since she was grade accelerated. How many just-turned 7 year olds have the maturity to take a timed test like that, esp. if it is two grade levels ahead of their age?
She had to also take the CogAt when she was grade accelerated in K, and I don't know what her scores were--just that the non-verbal was very high and verbal was just "ok", around the 90th percentile I think (so the opoposite of what we are seeing now with the verbal being highest). That version wasn't timed and was given to her orally. She also wasn't medicated at all back then so I'm surprised she wasn't dancing around on the table.
