Importance of secondary school in raising the individuals who have the necessary knowledge required in todays information society is gradually increasing. In order to evaluate measurement of efficiency which is most important part of performance Data Envelopment Analysis(DEA) is used. DEA is a non-parametic technique, based on linear programming. The purpose of the study is to determine efficiencies of the secondary education institutions in Van province by using data envelopment analysis. Moreover; to make suggestions to decision makers in order to increase the efficiencies of inefficient institutions and do improvement works. In the study, DEA is applied to 27 Anatolian High Schools in Van by determining their 3 input variables and 4 output variables belonging to 2018-2019 academic year, and their relative efficiencies have been measured. As a result of the analysis of the input-oriented model with the assumption of constant returns scale (CRS), 6 out of 27 Anatolian High Schools have been found efficient.
