Tex. Education Code § 51.154

The association is governed by a board of directors. The chief administrative officer, or a person designated by the chief administrative officer, of each institution of higher education holding membership in the association shall serve as a director of the board. Service on the board is an additional duty of employment of the chief administrative officers or the persons designated by the chief administrative officers of state-supported institutions and is not an additional position of honor, trust, or profit. The legislature finds that this service is necessary in accomplishing the purpose of this subchapter; is compatible with their employment; and will benefit the educational program of the institution and of the state.
