My 7 y/o DS1 is exactly like those described here. Very verbal, far beyond his age with vocabulary/ideas, but reading, writing and spelling are at the very low end for his age/grade, if not falling behind. I have yet to have him evaluated, but have been looking into that for this school year.
I have a question for those of you who have children like this and have had them evaluated. Have you noticed that your child also has some sensory issues? For example, DS1 seems to become very overwhelmed when there is a lot of activity going on at one time or a room is very loud, which makes it even more difficult for him to focus and it affects his ability to complete his work. (There are quite a few more things he does that make me suspect a sensory issue going on -- just trying to keep this brief by giving one example since that's not my question specifically.) Unfortunately his teacher last year did not notice any of this in him during class until the end of the year (which she admitted was due to the fact that she had a lot of loud/disruptive children) and only realized too late that he was having a hard time completely his work. I'm wondering if his possible sensory issues are a completely separate issue or if it might be related to his ability to learn the reading/writing skills?
I don't mean to derail the OP's original question. If this is better suited in it's own thread, please let me know and I'll gladly move it.
