Managerial Efficiency in Higher Education Using Individual Versus Aggregate Level Data. Does the choice of Decision Making Units Count?

This paper explores the use of a data envelopment analysis approach to decompose student's under-attainment in a part attributable to the Faculties they are enrolled in and a part attributable to the students themselves. The mean measure of each Faculty's teaching efficiency is calculated using both individual and aggregate data. The results show that efficiency measures at aggregate level reflect both the student's effort and the characteristics of the institution to which they belong, suggesting that they might lead to ambiguous results. The estimates also reveal that Faculties need to stimulate their student's effort in order to perform better
