Hi all,
Does anyone have experience with extreme subtest scatter? My grade 4 nine-year-old received three 19s on the WISC IV giving him a GAI of 99.9%. But he also received a three in coding. Does anyone know the rarity of a 16 point (19-3) subtest scatter? I'd like to know because the principal tells me that there are lots of gifted/LD kids in the school and she avoids making accomodations specifically for my son. But this extreme? How many children out of 1000 fit his profile of being in the 99.9% in some areas and the 1% in others? I'd like to be able to tell her the statistical significance.
Thank-you,
August
