* School Board: This is the most prevalent method. The locally elected school board hires and evaluates the superintendent.
* School Board with input from other stakeholders: Some districts involve community members, teachers, principals, and/or parents in the search and selection process, though the final decision rests with the school board.
* Mayor or City Council (in some cities): In some cities, particularly those with smaller districts, the mayor or city council might have a role in the superintendent's appointment, either directly or indirectly by influencing the school board's decision.
In short, there's no single answer. The best way to know who selects a specific public school superintendent is to check the policies and procedures of that particular school district.
