Gifted Issues Discussion homepage Forums Identification, Testing & Assessment validity of young test results (like WPPSI)

Brandy,

I don't think anyone online can give you a definitive answer since we don't know your son. It may indeed be that he just had a bad day while taking the WISC IV. Or it may be that he is better at the cognitive functions that are tested on OLSAT than those tested on WISC, after all each test assesses slightly different functions. Also keep in mind that WISC is purposefully very comprehensive and assesses many different functions so while your son may have done well in some subtests on WISC, he may had done more poorly on other subtests which summed up to a high average composite score.
