Each district shall undertake appropriate efforts to provide participation opportunities in district contracts without regard to race, gender or disability or other discriminatory bases defined in section 59300. Appropriate efforts may include vendor and service contractor orientation programs related to participating in district contracts or in understanding and complying with the provisions of this subchapter, developing a listing of MBE/WBE/DVBE and other persons or enterprises that are potentially available as contractors or suppliers, or such other activities that may assist interested parties in being considered for participation in district contracts.
