Not really sure if you've explored these at all--
crippling anxiety?
sensory integration issues?
Both of those would lead to difficulties under "load" which would disappear in more ideal environs.
ETA: Okay-- I just re-read your earlier thread about the saga with the preschool. Wow. Clearly, your DD (with the social precosity that she evinced for the evaluation above) was manipulating the entire situation for her own entertainment at least part of the time, and the teacher's response was a HUGE part of the problem there. I can't say that surprises me much in light of what I know about K-3 teachers as a group. They do NOT handle such children well, on average. It sounds like this one was outgunned and retaliated in the only way she had available-- by labeling your DD in any way that would allow her to eject her permanently.
{sigh} So. Here you are.
I don't think that your DD
can return to a "conventional" classroom. She's demonstrated that she either
can't tolerate it-- or that she WON'T-- which in terms of maturity and emotional regulation is more or less age appropriate and therefore amounts to the same thing.
The anecdotes that you shared in the earlier thread provide glimpses into the head of a person who is truly TRYING to meet others where they are... but experiencing severe frustration when they suddenly CANNOT understand her (and lacking the emotional regulation to 'fix' it or let it go in a graceful manner).
She isn't going to behave well unless she's engaged academically and has at least a few true peers. Good luck with that unless you live in an area with a fairly large pool of kids, because HG+ kids are not "common" by definition, and even if they were, kids have different interests and compatibility on the basis of personality. Ergo, she probably needs to have 3-6 children in her life who are at a similar LOG in order to function well socially.
That's my take. If that is all true, then it may get
better with age, but the only real cure is going to be to get her to practice empathy toward less-bright children, and to TOLERATE them better... which probably comes as a package deal with gaining more meaningful academic and social interactions. I think that her fuse is so short because she keeps getting stuck with extended situations which feel completely stultifying and overwhelmingly, mind-numbingly bad.
For the record, I'm also APPALLED that you were told that high IQ can't cause social problems. That professional ought (truly) to be ashamed. I think we can safely note that such a person is clearly not beyond ideally intelligent themselves, at any rate.
