Incog,
I'm sorry that I've forgotten, but is subject acceleration a possibility for your DD7? That seems to be a somewhat safe way to test the waters of a full grade skip, and there are usually a few others who have the readiness to go with her - so she doesn't have to chicken dance alone.
Where we are 6-8th is Middle School. 9-12 is High School in a different building. He's currently doing 7th grade, age 11. You hit the nail on the head, that if he doesn't make the switch this September, he will have to wait a full year for his buddies to make the shift. If he makes the shift sooner, he can be in ths same building with them for a year, while hopefully making friends in his grade to go with him to High School.
Kriston ((giggle)) You always are thinking, this is just a different kind of thinking.
