Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) is a unique rural development scheme implemented by Govt. of India from 2nd February, 2006. The scheme aims to provide an acceptable means of subsistence and livelihood by assuring 100 days of wage employment. In addition to eradicate rural poverty and unemployment, the scheme has given scope to impact on reduction of migration, agricultural productivity, financial inclusion, inclusive growth and women empowerment. This paper using secondary data attempted to assess the working and performance of MGNREGS in Karbi Anglong district of Assam with regard to employment generation, financial progress, women participation, inclusiveness of different social classes in the scheme. The study showed that female participation and inclusiveness of different social classes in the scheme were satisfactory. But inclusion of differently able people was less than the expected level. The study also showed that the scheme failed to ensure the 100 days job guarantee to the majority of job card holders during the period from 2015-16 to 2020-21.
