Just curious....how are classrooms formed? My daughter received her kindergarten assignment today and I'm not thrilled with the teacher, mostly because I know the other 2 teachers and I don't really know anything about this one. I'm going to sit tight and see how it goes, but I'm curious:

1. How are classes formed in the first place? What sorts of things do schools take into consideration when forming classes?
2. Is it annoying for schools to switch classroom assignments once the classes are formed? Should I even bother asking, or should I trust in the school administration's ability to put classes together and hope for the best?

thanks in advance!
