Effective with the term of office beginning on January 1, 2012, the county superintendent of education shall be appointed by the county board of education in any county wherein is located the state’s oldest state-supported university, having a population in excess of thirty-eight thousand (38,000) according to the 2000 federal decennial census and in which Mississippi Highways 6 and 7 intersect. Provided, however, if at any time prior to January 1, 2010, or ninety (90) days following August 10, 2009, whichever is earlier, a petition signed by not less than twenty percent (20%) or one thousand five hundred (1,500), whichever is less, of the registered, qualified electors of such county, exclusive of the municipal separate school district boundaries, is filed with the county board of education requesting that a referendum be called on the question of changing from the elective method of selecting the county superintendent of education to the appointive method, then the county board of education shall adopt, not later than the next regular meeting, a resolution calling a referendum to be called and held within the county school district boundaries upon the question. The referendum shall be scheduled for not more than six (6) weeks after the date such petition is filed with the board. When a referendum has been called, notice of the referendum shall be published at least five (5) days per week, unless the only newspaper published in the county school district is published less than five (5) days per week, for at least three (3) consecutive weeks, in at least one (1) newspaper published in the county school district. The notice shall be no less than one-fourth (¼) page in size, and the type used shall be no smaller than eighteen (18) point and surrounded by a one-fourth-inch solid black border. The notice may not be placed in that portion of the newspaper where legal notices and classified advertisements appear. The first publication of the notice shall be made not less than twenty-one (21) days before the date fixed for the referendum, and the last publication shall be made not more than seven (7) days before that date. If no newspaper is published in the county school district, then the notice shall be published in a newspaper having a general circulation in the county school district. The referendum shall be held, as far as is practicable, in the same manner as other referendums and elections are held in the county. At the referendum, all registered, qualified electors of the county school district, exclusive of the municipal separate school district boundaries, may vote. The ballots used at the referendum shall have printed thereon a brief statement of the purpose of the referendum and the words “FOR CHANGING FROM THE ELECTIVE TO THE APPOINTIVE METHOD OF SELECTING THE COUNTY SUPERINTENDENT OF EDUCATION,” and “AGAINST CHANGING FROM THE ELECTIVE TO THE APPOINTIVE METHOD OF SELECTING THE COUNTY SUPERINTENDENT OF EDUCATION.” The voter shall vote by placing a cross (X) or checkmark (✓) opposite his choice on the proposition. If a majority of the registered, qualified electors of the county school district who vote in the referendum vote in favor of the question, then the change in selection method shall be approved. However, if a majority of the registered, qualified electors who vote in the referendum vote against the question, the change in selection method shall not be approved.
