K Karnataka Nair Service Society (KNSS) was established in Karnataka on 8th June 1982, as a socio-cultural organization with the objective of promoting social welfare, education, cultural values, and community development. In furtherance of these objectives, seven dedicated Directors of the Board of Management of KNSS registered an Educational Trust on 3rd September 1987 in the name of Mannam Memorial Educational Trust (MMET), as the educational wing of KNSS.
The Trust started a Primary school in Kammanahalli in M.S.Nagar on 2nd October of the same year, to cater to the growing educational needs of the lower and middle class families of the area. The school, which started with less than fifty students, had become a fully developed institution as M.M.E.T English Primary and High School, offering quality education from Pre-Primary to High School level, in a short span of time.
Mannam Memorial Educational Trust (MMET) has been renamed as Mannam Memorial Educational and Charitable Trust (MMECT) on 5th January 2006, to reflect its expanded commitment to both education and social service. While continuing its mission of providing quality education at affordable cost, the Trust now also embraces broader charitable initiatives.
MMECT has taken over the management of KNSS Vidyamandir English Primary and High School in 2012. The school was established by the Dooravaninagar Karayogam of KNSS in 2006. The school is located in Mannamnagar, off Thambuchetty Palaya Main Road in KR Puram Hobli Bangalore South Taluk.
