I've seen it mentioned several times on the board and other places that the WJ III COG is more diagnostic in nature and that a GIA score can be lowered by processing speed and therefore a low score may not mean not gifted. But is the reverse true too? Is a GIA score that is *raised* by processing speed mean that it is inflated and that the child is not necessarily highly gifted? How much lower would they probably score on the SB-V or WPPSI?
DD4y8m took the WJ COG this week and got a GIA of 156, but I think it was raised by a Cog Efficiency of 157 which is composed of two of the subtests that Dottie marked as doubtful - processing speed and short-term memory. How much does processing speed raise or lower the overall score?
We had her tested to use in advocating for a grade skip to 1st. This last year she seems to have lost a lot of her lust for knowledge, hasn't progressed much in reading or math, lots of behavior problems/willfullness, refuses to do the new academic things her teachers got for her at her montessori preschool, but then complains that she's bored with the old "baby things" there, etc. etc. I am hoping that a grade skip will turn her back into the bright inquisitive child from before, but was also thinking that maybe I had had it all wrong and she's not really that gifted, especially after reading about all the HG kids here for the last few months.
I'm swaying in and out of gifted denial and just wondering if her WJ scores confirm gifted or if the verdict is still out...
The information and advice on this board has been invaluable - thank you.
