I have to say the only problem the processing speed problem seems to have given my son is in the taking of IQ tests. He was given a screener for the gifted program at his new school last year, the Cog/At, and scored in the 81st percentile. When I later read that this test was heavily weighted towards processing speed I asked that he be given another screener. He was given the Ravens for children aged 5-11 even though he had just turned 12 a week before. He made a perfect score, which would indicate a non-verbal IQ of 130-plus.
But, then he was given the Reynolds and got a verbal IQ of 136 and non-verbal of 105 and ended up being rejected for the gifted program, which did not make me happy one bit.
But anyway, on typical achievement tests he normally scores in the 97-99th percentile in both math and English. I suspect the processing speed is causing some problems with the reading section, but I'm not sure we could get extra time, since the school doesn't recognize him as having any problem.
