Geo, sounds like you laid some good groundwork. You certainly can't fix an iffy teacher in one meeting.
If you think this IS isn't going to rise to the occasion, can you meet with the LA teacher and talk about your DD, just to get her perspective, make sure she knows what the challenges are, see if you can get her on board with some of the multi-sensory strategies (the ones that would really benefit all the kids), and get her watching for the bullying? Pick the most important things, and see if LA teacher will help get your DD ready for the MS language arts program? You need someone to take responsibility for bringing her up to that bar.
Or is there a gifted teacher who could help with some of that?
The good thing about your DD having 9 teachers (!!!) is that if one of them isn't that great, the other 8 can still likely get her where she needs to be-- if they understand her needs.
