The Board of Trustees acts as the school district's policy-making body and is the official representative of the people for all public education in Central ISD.

The Board functions according to state and federal laws, the rules and regulations established by the State Board of Education, the Texas Education Agency and the will of the people as expressed in district elections.

The seven member board, while composed of individuals, acts officially only as a group. No member or group of members acts in the name of the Board unless authorized by the Board. A majority of the Board constitutes a quorum for the transaction of business. Individual trustees, serving without pay, are elected for three year terms on a rotating basis. Elections are conducted on the second Saturday in May.
