The School Board is composed of seven members, mirroring the local legislative body (Board of Mayor & Aldermen). Members are elected to four-year terms (every other year) by the citizens of Millington. Elections are held in November, with installation of new Board members in December. The Board is a corporate, policy-making, body that sets the vision for the school district and adopts policies to implement and support that vision. The Board is then responsible for promoting the schools and the school district.

Regular business meetings are held the first Monday of every month at Millington Central High Performing Arts Center (PAC). Work Sessions (if needed) will be held the third Thursday of each month. Special called meetings are held on an as needed basis and will be announced.
