Hi,
You have a real situation here. First, you need to tell the school to stop
calling for you to pick her up. If they can't handle her then they need
to look at a different placement.

There would be a way to do a residential placement. This would fix it so you still have custody of her. But the school places her in a residential placement. This would be revisited every year.

If you can tell me which state you are in I might be able to help find you a advocate that can help you get this kind of placement.

I'm a parent advocate in Indiana and this is part of what I help do in cases
like this.
But for one thing. As long as you let the school send her home, then they will not take responsibility for her schooling.
