I could be wrong, but I don't think his teacher was trying to cap his achievement. She said she started at a level 30 which I assume was where she estimated he would be. She said she moved backwards level by level, until she hit a level 21, which involves visual cues. I will ask her at the meeting we have scheduled in a couple of weeks whether she had thought he would score higher or not from his fluency. But also, from my own experience with trying to probe his comprehension, I had questions over his comprehension. I was relieved at the private assessment that showed he was comprehending a lot, but I find the teachers' assessment more consistent with my own experience working with him.
I agree that all the behaviours are typical for a 5.5 year old. I guess it is a matter of extent and frequency. Maybe it would be better to wait 6-12 months and get further evaluation done if his behaviours appear not to be ageing appropriately with him, and his reading comprehension doesn't seem to be improving.
