A chief executive officer of public schools, or CEO of schools, is an educational professional who is responsible for the administration of a public school district. Similarly to a receiver, CEOs replace traditional superintendents in managing the daily operations of struggling school districts in an attempt to improve failing schools. With the introduction of private market ideas into the school system, CEOs are generally given unilateral power to enact necessary reforms. This concept was first introduced by the Chicago Public School System in 1995.
