Resource Utilization and Economies of Size in Secondary Schools

This paper identifies the determinants of costs per pupil in English secondary schools. A distinction is made between the short run and the long run in order to estimate the separate effects on costs per pupil of short-run variations in school output and school size. A school's capacity utilization rate is used to indicate short-run deviations in output from pupil capacity, and pupil capacity is used as an indicator of school size to capture scale effects on costs per pupil. The statistical analysis uses both published and unpublished data for secondary schools in England. Two separate analyses are undertaken, one for grant-maintained schools alone and the other for all schools. A separate analysis is undertaken for grant-maintained schools since cost data are available only for schools in this sector. Staff hours per pupil is used as a proxy for costs per pupil for schools as a whole. The main finding is that costs per pupil and staff hours per pupil are both highly significantly negatively related to both school size and the capacity utilization rate of schools. A range of other variables are also estimated to have a significant effect on costs per pupil in secondary schools. The main finding is that there is scope for reducing the costs of schooling in the secondary schools sector in England
