CMS is the first school in the world to be honoured with the UNESCO Prize for Peace Education 2002 in recognition of its efforts “to promote the universal values of education for peace and tolerance at a time when these values are increasingly being challenged.”

The world’s largest school by pupils is the City Montessori School, Lucknow, India, which by September 2002 had a record enrolment of 26,312 pupils. The school was founded in 1959 by Mr. Jagdish Gandhi, a socially motivated Gandhian, along with his wife Mrs. Bharti Gandhi, M.Ed., a child psychologist. The pair launched their first campus on a borrowed capital of 300 rupees, housed it in rented premises and began with only five students. The school admits boys and girls between the ages of 2 and 5, who can then follow through their education to Degree Level. It is the only school honored with the UNESCO Prize for Peace Education (2002), and the only to organize and host 15 international events for children each year. The school’s inspirational motto is “Jai Jagat” . Please see Guinness World Records website: www.guinnessworldrecords.com
