I agree, I don't think that a teacher is going to be able to make unbias decisions. The teachers do have their place but not as president or co president of the board. Have you checked to see what your by laws say? They may help you out a great deal.

Our PTA is in the process of restructuring. We are creating new by-laws and new policies and procedures. At the end of last year I was elected President of the PTA - it was insisted by the retiring co-presidents that there should be a co-president. When no one else volunteered, they found a teacher to be my co-president. As the year progresses, it is becoming apparent that the teacher cannot be an objective participant in some of the decisions that are being made regarding the budget and programming. Both myself and the principal have talked with her raising the concern that being a teacher and PTA co-president is a conflict of interest. We have an executive committee in place that includes a number of vp's and a teacher liaison. I would very much appreciate advice and any precedent on this sensitive issue.
