The most important thing for her right now is to talk to her and make sure that this screw up does not effect her future outlook and performance. I've seen lots of A students drop to D students after being mistreated academically by a teacher. Make sure she doesn't take a "Why should I try if they are going to treat me like that?" attitude. This is where your parenting skills may prove quite valuable.
I have been to the school and cannot get a meeting with ANYONE, yet. They are very busy and she is not the only child in the school------They told me this on the phone when I asked that she be removed from the newest class. I have to wait until Monday to find out when I can get a meeting with the Principal and the guidance counselor. I, just really needed to know what kind of resolution I can ask for.
