In fiscal year 2015, Yuma Union High School District’s student achievement was lower than peer districts’, and its operational efficiency varied by area. The District’s plant operations and food service programs operated in a reasonably efficient manner. However, its per pupil administrative costs were much higher than peer districts’, on average, primarily because of higher staffing levels. Additionally, the District needs to strengthen its accounting, computer, and building access controls. The District’s transportation program operated with much higher costs than peer districts’, which may have been the result of insufficient program oversight. The District did not ensure that transportation charges were supported, adequate controls existed over fuel inventory and purchases, or that preventative maintenance was performed on buses according to schedule. Additionally, the District incorrectly reported its mileage for state funding purposes.
