What I always find interesting about these debates about the use of IQ tests which has been mentioned elsewhere is the willingness to use tests and measures to identify the LD but also the willingness to use tests and measures everywhere else, including sports, and even in the arts, but not with giftedness. Posts and blogs of these kind always say, sure there are outliers, but then discount the presence of them. And by extension discount parents fighting for them.
Even if you want to argue that people with high IQ scores are simply good at taking tests - that's a measure. Its real and quantifiable and not a fluke. How can it not be meaningful when a 10 year old scores higher on the SATs than comparable 18 year olds. It means something is different about that individual and that difference relates to the absorption of knowledge because if they had not absorbed the knowledge they would not be able to do better than their age cohort as well as better than older individuals with more time to master skills and knowledge.
It is so strange to me that you mostly get this argument from very bright people - as if they worry they can't achieve or succeed in life because some other people learn faster, see more complex connection or any of the other myriad things IQ tests measures. No one feels that way about the star athlete or the violin virtuoso.
