I would change tactics and ask the school psychologist to calculate the score with the extended norms, in addition to asking your ped or another psychologist to request the scores. I calculated one of my DS' GAI scores on my own, and then asked the school psy. to calculate his GAI. Your post reminded me that I need to go back and ask her to look at the extended norms (which was something I didn't realize could be done when we had the original testing done last year. )
In what situations should extended norms be calculated? How can I tell whether or not extended norms should calculated (in order to request it)? When the subtest score is 19? 18? How can I tell if it has been calculated?
