The McKinney ISD Board of Trustees is comprised of seven board members who are elected by the general public to serve for overlapping terms of four years each. MISD Board members are not compensated for their service on the board. Elections for board seats are conducted annually each May. The candidates run for specific places on the board (Place 1, Place 2, etc.), but they represent the McKinney ISD as a whole. Once elections are finalized the Board elects a president, vice-president and secretary for one-year terms.

It is the responsibility of the McKinney ISD Board of Trustees to function under the legal parameters of the state and federal constitutions, statutes, courts, and administrative agencies. MISD Board members are responsible for providing the best educational opportunity possible for the students in McKinney ISD. School trustees are also responsible for making all final decisions regarding school district priorities, policies, personnel, textbooks, expenditures and growth management. The MISD School Board Trustees will adopt a budget that will properly maintain and operate all schools in the district, levy taxes to support the budget as well as determine and submit bond issues to the voting citizens of McKinney regarding the need to finance specific construction projects.

Working as a team of eight in conjunction with the Superintendent, the McKinney ISD Board of Trustees are an elected governance board with a shared sense of purpose focused on meeting the needs of all MISD students and the communities they serve.
