Texas law grants the board of trustees the power to govern and oversee the management of the district's schools. The board is the policy-making body within the district and has overall responsibility for the curriculum, school taxes, annual budget, employment of the superintendent and other professional staff, facilities, and expansions. The board has complete and final control over school matters within limits established by state and federal law and regulations. The board of trustees is 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 at-large and serve three-year terms. Trustees serve without compensation, must be registered voters, and must reside in the district. Trustees usually meet the third Monday of each month at the Hamilton Junior High School Library, 400 South College, beginning at 6:00 p.m. All meetings are open to the public. In certain circumstances, Texas law permits the board to go into a closed session. Closed session may occur for such things as discussing prospective gifts or donations, real-property acquisition, personnel issues including conferences with employees and employee complaints, security matters, student discipline, or to consult with attorneys regarding pending litigation.
