Measuring the Technical Efficiency of Educational Units – An Interesting Find

Abstract

This paper empirically investigates the existence of differences in the measurements in Technical Efficiency for upper secondary public schools in Greece during the years 2020, 2021 and 2022 with implementation of Data Envelopment Analysis and Stochastic Frontier Analysis. The findings show that the results are close. The mean value of the differences (d) is 0.00022, and the standard deviation is 0.083. The application of SFA is performed with the Cobb-Douglas model, Half-Normal N⁺(0, σ²_u), which was chosen among four alternatives, since it presents the best adaptation to the empirical data. Therefore, in the area of applied policy there is no need to apply both methods.
