to continue its functions. A 12-member Sunset Advisory Commission oversees the provisions of the Texas Sunset Act. The commission consisting of five members of the Texas Senate and one member from the general public appointed by the Lieutenant Governor of Texas, and five members of the House and one member from the general public appointed by the Speaker of the Texas House of Representatives. Legislative members are appointed for four-year terms, with half of the commission reappointed on or before September 1 of odd-numbered years, while public members serve two-year terms. The chairman and vice-chairman are appointed by the lieutenant governor and speaker, and the chairmanship alternates between the Senate and House every two years. The commission is assisted by an executive director and staff, who review each agency subject to sunset provisions. Under the process, each agency must perform for the commission a self-review of its roles and responsibilities, including areas where its duties may overlap those of other agencies and the effect of the agency's abolition on loss of federal funding. The self-review must be completed by September 1 of the odd-numbered year before the year when the agency would be otherwise abolished. The commission must then complete its own review by the following January 1 and hold public hearings by the following February 1. About 20 to 30 agencies go through the sunset process each legislative session. Constitutionally established agencies are subject to review, but they cannot be abolished under the sunset provisions. The commission may recommend that an agency be continued in its present form (nearly always with recommendations to the legislature for improvement), consolidated with another agency, or abolished, with its duties either eliminated or transferred to other agencies. Other states Alabama has a similar review process with a more limited number of agencies and a review cycle of every four years.
