I don't really feel qualified to offer advice as I haven't had to deal with a teenager YET, although my D displays some of the rebelliousness of one already.
My first reaction to your idea of pulling her out of school to home school for the rest of the year, was why not explore less dramatic options first? If, as you say, she has good friends at her present school, could you pursuade her/them to come to some sort of understanding that they provide your D with some moral support? Form a protective wall around her for a while, to get her through this difficult period?
You haven't really told us what your D's reaction to all this is. How did she react to having you called to the school etc? Is she still rebellious or has she agreed to work on a solution?
As for home schooling, I was very into the idea before D was even old enough to be schooled, and got a load of books, but decided that in my circumstances it was not practicable.
I think if your D is willing to work on the problem herself, with your support, then carrying on at her present school should be her first option. Just an outsider's view.
Sorry you have had another problem lobbed at you. But I have every confidence you all will work it out.
Have you figured out which DBing principles can be applied to this situation?
