OK, I finally read the Extended Norm manual and converted the scores. It really only changed his VCI, which went from 148 to 170. GAI also went up a lot (to 167), FSIQ not so much because the WMI and PSI were still low.
So I now have a picture of a kid who's even MORE wildly uneven...
Makes sense, actually.
It was only his vocabulary score that was crazy high (scaled score 25)
By the way the more I try to explain these results to my husband-- to say, look there really is something funny about this kid and we have to do something-- the more crestfallen he looks at my obsession, his eyes sort of darting to the piles and stacks of papers accumulating on the desk...
I don't know about Canadian test results, but the extended norm technical report and conversion charts are online, just google WISC Extended norms
Obsessively yours.
