I would hope that what you have done so far, would be enough to have this aide removed. Here's what I would do if what you have done so far does not yield results. I do not know how many children are in your DD's pre-school class, but I would call each and every one of their parents, to see if they or their kids have had problems with this aide or if their kids have been complaining about the aide or not wanting to go to school. You already have 4 mothers who clearly have the same problem you do. Other parents who have not been talking together may not realize that an issue their child has had is not isolated. Some parents may think their child is just adjusting to a new person or acting out, not realizing that it is a widespread problem with the aide and not their child. If this aide is as bad as she sounds, I'm guessing almost every parent is going to find out their kid has an issue with this aide. Then I would schedule a time for all the parents to go together to the pastor and/or school board member and voice your complaints. I would tell the pastor/school board that either this aide goes, or each and every one of your kids is going to be pulled out of this preschool. I'm guessing the minute they hear they are potentially going to lose tuition for a good chunk of the class, this problem will be taken care of. You might even call the parents from the other class and see if they have the same issues too. In this kind of deal, there is definitely strength in numbers. Good luck.
