My main fear is that putting her alone into a classroom of kids 2-3 years older will be socially isolating anyway - both within her grade 'peer group and the other class. Additionally, another class designed for an NT audience i(no tracking here) is just not going to progress and her speed to concept acquisition.
A sensible concern. I had the same one about isolation from the regular class when my DD's school proposed the GT pull-outs, and they assured me that all their kids are going to a variety of pull-outs all day, so it wouldn't make her look unusual.
As far as age, that wasn't something we worried about, because DD always seeks out and befriends the oldest kids in any mixed-age activities (drama, gymnastics). How does yours get along with older ones?
