This paper focuses on the efficiency in employment generation by MGNREGS in the states of India by gauging different indicators such as the Average Person Days Creation (APDC), Percentage of Fund Utilization (PFU), number of Job Card Issuing (JCI) per 1000 population and performance in creation of village infrastructure. The Stochastic Frontier model was used to estimate the technical efficiency in employment generation by MGNREGS between the states during the period from 2010-11. The efficiency rank analysis showed that the north - eastern states performed well as compared to the other states of India.
