Interfere with the Head's job of managing the staff. They are neither expert in educational administration nor is this their job. They define the kind of school that they want and hire the Head to turn their dream into reality. The Head hires and supervises the staff that actually works with the children. Don't let your board spend its time on non-board issues Every time an issue comes before the board, the question should be asked whether or not this is really an appropriate board issue, or should it be referred to the administrator.
Boards set policy, administration and staff implement it.
Effective boards use the Head wisely. Before considering a new issue, effective boards commonly ask the administrator to do some research and recommend alternatives. Boards should be constantly thinking about where the school will be in ten to twenty years hence, and how it will get there. Contracts are forever. Whether it is a contract for a new janitorial service, an enrollment agreement or a contract for employment, each commits the school to whatever is spelled out in writing.
