Okla. Stat. tit. 70 § 9-109
The State Board of Education is hereby authorized to request a price list and a complete description and specifications of any transportation equipment to be offered for sale to any school board or board of education of any district in the State of Oklahoma.
The State Board of Education shall examine such equipment to determine whether or not such equipment meets the requirements of the National School Bus Standards and such other specifications as the State Board of Education may determine as necessary to provide safe transportation for pupils to and from school and shall approve for sale to all schools in the State of Oklahoma transportation equipment, including bus bodies and chassis, which equipment meets or exceeds the specifications provided for the National School Bus Standards and such other specifications as the State Board of Education may deem as necessary. Any equipment fueled by alternative fuels as defined in Section 130.13 of Title 74 of the Oklahoma Statutes shall also meet any federal safety standards specified for any equipment used to provide transportation for pupils to and from school. The State Board of Education may approve auxiliary transportation equipment that is not National School Bus Yellow in color.
The State Board of Education shall make a list of the equipment approved by them and the maximum price at which such equipment can be purchased. The list shall include a complete description of the equipment. Such description shall include the specification of the school bus bodies and chassis as well as the factory list price of such equipment at the various factories. Such list shall be made available to all school districts authorized to purchase transportation equipment. Provided, at any time there shall be any change of specifications or prices by manufacturers of chassis or bodies, there shall be filed with the State Board of Education a revised set of specifications and prices.
The school board or board of education of any school district authorized to furnish transportation for pupils to and from school and receiving any State Aid funds, except as provided for in this section, shall be required to purchase all their transportation equipment from the list so provided on sealed bids and at a price not greater than the price filed with the State Board of Education; and the State Board of Education shall be required to deduct from any State Aid for which the school district may qualify the amount paid by any school district for transportation equipment not approved by the State Board of Education or the amount paid greater than shown on the price list for that transportation equipment filed with the State Board of Education. Unless otherwise exempted by this section, all purchases made under the provisions of this act for transportation shall be made upon sealed bids, and contract of purchase shall be awarded to the lowest and best bidder.
Provided, however, any purchase or sale of used transportation equipment shall not be subject to the list and sealed bid requirements as provided for in this section.
The State Board of Education shall adopt rules necessary for the administration of this section and shall require from school district boards of education such information and reports as necessary for proper administration of this section.
Any cost of administration of this section shall be paid by the State Board of Education from funds appropriated for the administration of the State Aid Law.
