Good luck with the new school situation - hopefully you will get the testing you need and your daughter will get the challenge she needs. Keep working on the prefectionism! Try to model aloud your own self talk when you get frustrated.
It's hard to estimate LOG - they are all certianly 'age appropriate' at times. Deb Ruf's book '5 levels of giftedness' might help. Time spent in classrooms observing other kids of similar age can help.
I'm not so sure that OEs are 1:1 to LOG. I like better the idea of accepting each kid where they are, getting self-support for the extra stress the OEs cause, and I'm hoping that meditation will turn out to be helpful to teach everyone in the family to modulate the OEs. I was lucky in that we didn't know about OEs, because I would have probably just thought I should live with them, until after we already got help with them from and Occupationial Therapist who specialized in 'sensory integration disorder.'
I like the idea of OEs, but I dislike that there isn't much one can do about them. I know that mine have improved dramatically since I started meditating in August.
Love and More Love,
