Amends GS 115C-249 to require that in determining which school buses in the statewide fleet to replace using state funds, the State Board of Education (SBoE) must consider mileage, the safety and condition of the bus, availability of funds to replace buses, unique circumstances about a given bus, and damage to or destruction of a bus, but not the age of the bus. Requires that if a school bus is operated for 250,000 miles or more, but not more than 300,000 miles before being replaced using state funds, the SBoE must allocate a $2,000 bonus to the local school administrative unit that owned and operated the bus. Increases the bonus to $5,000 for a bus that is operated for 300,000 miles or more before it is replaced. Allows the local school administrative unit to use the bonus funds for additional maintenance costs of operating buses with higher mileage or for any other school purpose. States the General Assembly's intent to appropriate funds to purchase school buses to replace buses with specified mileages. Effective July 1, 2013.
