MTCES was born out of the vision of two visionary bishops of the Mar Thoma Church, Dr Juhanon Mar Thoma Metropolitan and Rt Rev Mathews Mar Athana-sius. It was a time when our people from all parts of the State, particularly from Central Travancore, who had gone abroad for employment, felt the need for a good residential school to educate their children, upholding traditional Christian values and culture. People belonging to the Mar Thoma community, who had migrated from different places to Trivandrum, also wanted a good school in the capital city for providing quality education to their children. When the historic decision to establish educational society in Trivandrum for imparting school education was taken up by a small group belonging to St Thomas Mar Thoma Church Pattoor, under — readership of the Vicar Rev K O Sam, it was a small step towards a great cause.
Registered on 11th May, 1966, the MTCES, now well established and prestigious,had a modest beginning. It started functioning with the establishment of St Thomas Residential School (STRS) on 06-06-1966 with six students in a rented building at-Nanthencode. The Society initially enrolled 260 members. Executive Committee was constituted with 11 mem-bers of whom two - Dr E T Mathew and Prof. Anna George - are still with us actively participating in our activities. The first General Body meeting was held on 10th December, 1966. Within a short span of time, the School was shift-ed to the Mukkola Campus. In 1986, there were 750 students in the School, of which 350 were boarders. The Mar Thoma High School following the State Syllabus which was started in 1984 was later renamed St Thomas High School and later St Thomas Higher Secondary School. The Kuwait war in 1990 saw large number of our people returning to Kerala with their families. Getting admission for their children to continue their education during the middle of the year was very difficult. The Society considering it as its social responsibility to help the children started the St Thomas Central School affiliated to the CBSE Board. In 2005, we entered another phase of development by starting the St Thomas Training College. Later the Society acquired about 20 acres of land near Kazhakuttam and started the St Thomas Institute of Science and Technology in 2010. The St Thomas Public School was established in 2014 to cater to the rising demand of parents from Technopark and other institutions adjacent to it. Our institutions are well appreciated by the parents and society at large. Today, we have a total of 8,950 students, 300 teachers and 360 non-teaching staff on the rolls.
