That should have gone straight to the principal and then to the school board. If that didn't get immediate effect, then it should have gone to the local newspapers.

That was the same year that the district was short textbooks. My daughter was one of the students who was chosen to not to receive any text books. They said that since she was an athlete, I wouldn’t mind if she didn’t have any books and that none of the other parents had complained. They didn’t even keep one set for the class rooms or the library, so one whole class of students had no books for any subject.
