That is a tough one. Do you know any families who have been through similar? If the district is good at identifying GT kids then maybe this IS routine for them.
I guess I'd ask how many 6th grade students were placed in Honors English 7 this year, to get an idea of how unusual this request is.
BTW - The year before the change of building is said to be the one that is key for the organizational skills growth. What about revisiting the idea of applying for a whole grade skip? You can perhaps 'back out' partially once you have the approval, or even wait 3 months and see how it's going.
If you dd isn't 2E, then it's quite possible that she'll have a nice challenge with the time management and org skills. She may not be a straight A student right off the bat, but how satisfying for everyone to see her work for it! Do 7th grade grades count in your district? Can you put her in a private school to repeat 8th if she isn't ready for high school at the end of 8th with the full skip?
Don't you wish that there was a little table, or an iphone app where one could program in the IQ scores, and info about the school district, and 'bing' out would pop a prediction about the outcome of various educational outcomes?
If she isn't having a wonderful time socially and is actively unhappy academically, I'd go for the full skip. If she's doing 'fairly well' and you just want to 'tweak' I'd consider afterschool mentoring, or apply for the full grade skip and then back out at the last minute, trying to keep the LA acceleration. Socially, I think that before high school subject accelerations are more difficult socially, except for the few kids who are very very at home in their own skins and seem to like it.
Let us know - good luck!
