He sounds kind of like my DS, who is now almost 7. He had a lot of delays with speech, language, and motor skills as a toddler/preschooler. Cognitively he always seemed bright but his speech kept him from appearing bright. Ultimately he was diagnosed by a neuropscyh with developmental coordinator disorder/dyspraxia last year. He has had two IQ tests and his score went up a lot the second time. So first time when he was 3, he was in the average range (but there was a big gap between verbal/non-verbal with non-verbal being a lot higher). Second test when he was 6, he had the same gap but everything had shifted upwards about 20-30 points, putting his GAI in the gifted range, with non-verbal being super high in the 140's.
Looking through his records, no one would have ever been able to predict that would occur and that he would advance so much as he aged.
I think on the verbal section of the WISC he has a problem with speech, and the test isn't going to pick up on verbal ability unless a child is good with expressive speech. If a kid isn't very articulate, they are not going to get good scores, even if they understand the concepts. I am probably going to take DS in for more testing, because while his expressive language is greatly improved, I still think he struggles. speech/language impairment is one feature of DCD.
What kinds of delays have you seen?
