Thank you ash- I updated the post to remove his name. Thank you for also listing other possible explanations. I'm pretty certain he is unfamiliar with timed tests, and my guess is that it probably made him a bit anxious. His fine motor skills I believe have now caught up to age-appropriate, but are by no means a strength, so that could play a part too. You mentioned his block design subtest, and he scored an 18 on that, which she stated was very superior, so I'm not seeing a problem there at this time.

I guess now we move on to... what do we do with him? I feel our school is willing to work with us, but I'm not even sure what to advocate for. He said yesterday that he didn't like science, which surprised and saddened me. I responded by saying, "That surprises me, because it seems you like SnapCircuits, electricity, magnets... animals and their habitats, plants and how they produce oxygen, chemistry, ramps and levers, etc. and those are all science..." He then clarified that he doesn't like science at school. Overall, he loves school, especially his advanced math class. He does not want to talk of ever possibly switching schools, or going to another grade than his friends (expect for math...). I'm grateful he's happy, but I'm concerned anytime school starts to diminish his interest in learning.
