Besides knowing that the dismissal was not racist, I have no insight on that actual decision. I do know that it is a tough job in a difficult district. I do know that discipline problems come in contact with the principal and his/her assistant. In my time, I was sent there so often that my shoes could find the way on their own. Despite all those trips, I never met or even knew who the superintendent was.
I would hope that the next hire is based solely on ability, and that the person is given enough time to prove their worth.
