Who evaluates principals?

Editor:

We are writing this letter to express our dismay about a situation that exists in our town. We love children and have devoted much of our lives and work to developing them to become future leaders. We are homeowners and voters in Alameda and active participants in civic affairs. 
We are dedicated teachers and have taught every grade from preschool through high school. We have also worked in several corporations as programmers and managers. We have supervised student teachers and employees. We are members and officers of Zeta Phi chapter of the International Women Educator’s Honor Society, Delta Kappa Gamma.
It has come to our attention that one of our very fine new teachers was “non re-elected” and asked to resign. This means that she must leave our school district and cannot teach here. What a loss to our children and community. 
It doesn’t make sense, for this teacher is well regarded by parents, loved by her students, admired by many of her colleagues and greatly appreciated by the volunteer assistants who work with her in her classroom. She has also received excellent reviews from her principal and supervisor.
However, this same principal has “non re-elected” 11 other teachers in the last three years. Many parents have reported transferring their children to a different school because they didn’t want their child to be in a school with that principal making those decisions. 
There are many procedures set up to evaluate teachers, to discharge or rehire them. What practices do we have in place in our district to evaluate principals and to achieve fairness and justice for all?
