The problem with the non-compliant child is the school comes back with "she won't even do X so we don't have to do anything else for her". Her teacher thinks that she should take some initiative to challenge herself in her work.
Ugh. We're dealing with this now with DS5 (early entry into first grade). We're having behavioral/compliance issues which may or may not be GT related. Plus, we're getting a little bit of nonsense from the school that the burden is on DS to "show what he knows."
With about half the school year over, we're starting to think that we went in the wrong direction. Of course you make the best decisions you can at the time.
Unfortunately no real advice except for condolences that we've been there.
