To improve the units’ efficiency and productivity in recourse management of organizations, it is valuable to evaluate them, which is strongly dependent on their present situation. Using inputs and outputs out of real data, Data Envelopment Analysis (DEA), a suitable tool for evaluation, calculates the relative efficiency of the Decision Making Units (DMUs). The paper utilizes DEA to evaluate the performance of Public high schools in the first division of Shiraz in Iran in 2182-2182, for three approaches; School facilities, Students, Educational environment by the help of CCR model in DEA-Solver software. Finally, some suggestions are presented for deficient DMUs in order to approach to efficiency border and some sensitivity analyses on the inputs/outputs data of DMUs are provided
