Wincha,
If this keeps up, your daughter is not going to be able to GO to school. Anxiety works that way. I think you need to get a clear definition of "disrespect" which does not include, in my opinion, asking a question. I would also ask for clear rules and consequences--so that she is not sent out for these picky things. (by the way--3 hours is ridiculous for what you describe.) All the things that come to mind require qualification which is why they do not want to qualify her. It will give you a lot of power. Is there another teacher at her grade level?
I do not understand your SD--given their behavior, IF your daughter were already Special Education qualified, I would say that they are trying to drive her into a more restrictive placement-to get rid of her. However, since they are also fighting qualification, it seems they are just trying to drive her crazy.
This is really disgusting of them.
