Howdy, writing back because we now have some WISC scores, remarkably similar to your ds' GTC -
We are looking at a GAI of 124, vci being stronger than pri by a bit and definitely low processing speed (88?). I think the term is 'average low'. Sorry I am writing without the scores in front of me.
Wmi is average, so basically the tester wrote up a brief report to get to the school by the deadline for assessing for next year's gt program, but with VCI being his highest # at *only* 95 percentile, unless we have really good reading scores or something similar in writing, he might not edge into the program.
Ah well.
We are still waiting on WJ scores, and more info from the doctor as to what the big picture and outlook for ds is going to be. But, with a psi below avg., he said we have to look at requesting accomodations on any serious timed testing going forward. Isn't this WISC thing timed, lol??
I was very happy to see an Arithmetic score of 13, coming in rather better than the 35(!) percentile score he'd gotten on the Cogat quantitative - that had me really wondering. I guess that Cogat is really boring for some kids!
Anyway, I do wonder about all this working memory and speed being 'set for life', as you have wondered gtc, and the doc has mentioned adhd and aspergers, we have filled out form after form, diagnostic, etc. Whew. He indicated that, yes, this is fairly set...but still my own experience has been different and you gotta wonder about the stuff they didn't really know about the brain just a couple of decades back.
OTOH, if accomodations on the SAT,etc., are available, I will definitely look into them, I won't put my nose up to that!
Hope this post makes some sense, dashing off to make dinner...
