The following is a description of School Board Policy from the National School Board Association:
School Board Policies
Policy: it is a crucial school board role in our system of education governance. Like Congress, state legislatures, and city or county councils, school boards establish the direction and structure of their school districts by adopting policies through the authority granted by state legislatures. School board policies have the force of law equal to statutes or ordinances. Policies establish directions for the district; they set the goals, assign authority, and establish controls that make school governance and management possible. Policies are the means by which educators are accountable to the public.
