Currently, due to the considerable number of banks and financial and credit institutions in the country, also due to the privatization process of state-owned banks and the conversion of credit cooperatives and credit financial institutions into banks, their performance evaluation has become important. The purpose of this paper is to provide a method for evaluating the performance of banks and financial and credit institutions. In this research, using experts' opinions and library studies, banks' performance evaluation criteria were evaluated in two stages of 18 branches of Melli Bank, then two-stage data enveloping analysis method was used to evaluate the performance of branches and finally rank them. The studied indicators were categorized into two stages to evaluate the performance of branches.
