I was wondering the same thing as blackcat - how old is he now and how old was he when first tested? I would also look at his 2e issues, and try to make sense of how they are impacting his test scores, as well as look at the tests administered both times. Was he tested with the same test? I'm also wondering... did you see indications of his LD when tested the first time? I'm guessing you did since you mention GAI and not FSIQ. Is it possible that the impact of the LDs on test results is more significant now than it was three years ago?
I have a dd who's GAI dropped significantly between testing at 5 and testing again at 8. In her case, she had a significant drop in subtests that were tied to vision (and was then diagnosed with a visual challenge), but she also had an overall general drop in scores. She was tested with the WPPSI at 5, and the WISC at 8. I believe that the later WISC scores are more accurate in her case, because they reflect more of what we see in academic performance and also what we see in standardized testing.
