The Hempstead ISD Board of Trustees is made up of seven board members who are elected by the citizens of the district to represent the community's commitment to a strong educational program for the district's children. Trustees are elected each year in May and serve three-year staggered terms. Trustees serve without compensation, must be registered voters and must reside in the district.

Trustees are elected to a specific place on the board (ex. Place 1, Place 2, etc.) although they represent the entire district as a whole. Each year after the election is finalized, the Board elects officers (president, vice president, and secretary) for a one year term.
