The Texas State Board of Control was abolished in 1979 (House Bill 1673, 66th Legislature, Regular Session). Its duties and responsibilities were transferred to the newly created Texas State Purchasing and General Services Commission. The Commission is composed of three members appointed by the Governor with the advice and consent of the Senate for overlapping six year terms. These are nonsalaried positions and the Governor appoints the chair.

The commission is responsible for providing an effective purchasing system for state agencies; providing maintenance, repair, and security services to the Capitol Complex; operating a central telephone system for state agencies; handling the lease and rental of space required by state agencies; and acquiring real property in the Capitol Complex and constructing state office buildings. The commission acquires all supplies, materials, services, and equipment for all state agencies, with a few exceptions. It does not acquire property for the Texas High Speed Rail Authority, library materials for libraries operated as part of institutions of higher education, or certain materials for state-owned hospitals and clinics. For administrative purposes, the commission is organized into eight divisions. The Executive Administration Division adopts rules and establishes policies for the efficient performance of commission programs. The division provides legal services to other commission divisions, along with independent audit review of all commission operations.
