This study examines the performance of Indian commercial banks for the period 2011-2013. Study has utilized the mathematical programming based non parametric technique i.e Data Envelopment Analysis (DEA) to evaluate the relative efficiency of various Decision Making Units. DEA technique is used to evaluate the technical efficiency scores using CCR (Charnes, Cooper and Rhodes) model and pure technical efficiency scores using BCC (Banker, Charnes and Cooper) model, which are popular among all other methods. The objective of this paper is to evaluate the extent of technical efficiency in 46 commercial banks operating in India. The study categorizes the most efficient banks which act as benchmarks for other banks. The results show that only 10 of the 46 banks are found to be efficient and thus, defined the efficient frontier.
