Important updates:

I had another look at his testing results and WOW. I have no knowledge in the field (save what we've been learning along the way with DS6), but I find some of his results on the WIAT III to be a bit shocking:

Early reading: 75th percentile
Decoding nonsense words: 12th percentile!
Reading sight words: 19th!

The psychologist attributed this to the fact that he's in Early French Immersion. But isn't that too significant to be attributable only to that one factor?? She was so dismissive of it at the time that we didn't even register that it might be a problem.

Plus, we spoke to his English teacher and she said that he complains of a sore stomach and has to go to the bathroom every single time he has to do any writing.

At this point, I think we need to have him tested. Now we just need to figure out if that can get done through the school.

Oh, man.
