Unfortunately, most of the morons in this country don't understand that the purpose of the school board is to represent the taxpayers. So they vote for teachers to fill the vacancies or don't vote at all. (Fox guarding henhouse)
Unfortunately, almost all power has been stripped away from local school boards by state and federal laws anyway. All that is left is a facade.
When a local school board today sets its budget, well over 90% of what they spend the money on has already been dictated from above and from afar.
And the control of the cash amounts to control of virtually everything.
