In most States, the public education system is further divided into local school districts, which are managed by a school board, representing the local community. School districts can be small, covering just a small town or rural county, or enormous, covering a whole large city; according to their local policy, they are responsible for coordinating education policies, planning for changing educational needs in the community, and often even establishing programs and curricula. They will also delegate a varying amount of freedom or independence to each individual school within their sector (with some exceptions, such as general rules concerning health and safety).
