Efficiency analysis in education: An application of the StoNED method

Abstract

In Colombia, numerous methods have been implemented to measure the effi-cacy of secondary education institutions. The purpose of this study is to estab-lish the efficiency of these institutions, using an innovative methodology known as Stochastic Non-Parametric Envelopment Analysis of Data (StoNED) with an output-oriented measurement. A visualization of the relationship between efficiency and the management of the education secretariats by department is proposed. Institutions are taken as decision units, based on the results of students’ SABER 11 tests, considering two levels of aggregation, by institution and by department. A slight difference is found in the proportion of institutions that present technical efficiency with respect to those that do not. Moreo-ver, it is identified that most of the institutions that do not present technical efficiency are those of an official nature, and those located in rural areas.
