Where by the prestigious institute Named as St. Thomas Academy Senior Secondary CBSE School. It began on 17th June 2017 in a small class room with 90 students and 14 teaching staff and Non-Teaching staff.   Our School had faced its own trails and difficulties, but all these paved a way for a better success and shaped St. Thomas Academy as Prestigious institute with the initiative of Rev. Fr. Christuraj, the Correspondent at the time. He took it as a challenge to put up a beautiful infrastructure in a conducive atmosphere with all the facilities accommodative to the children and satisfying expectation of the parents who approach us to admit their children in our school. This beautiful building with all the amenities was blessed and opened on 12th August 2018 by our chairman Most.Rev .Dr. A. Neethinathan Bishop of Chingleput in the presence parents, Students and priests from our diocese. We are grateful to all those who in one or other way helped to Burgeon this institute to larger extent.

Today the institute proudly stands itself with 400 students and 25 teaching faculty and 8 Non- Teaching faculties with Principal Sr. Sandhya Rani JMJ in this new building.

The school also privilege to have the separate Director cum Correspondent  Rev. Fr. C. Paul Raj for this esteemed institute, in order to develop and to expand, keeping in mind the Motto our School “Aspiring for Excellence”. I believe that our Prestigious school march towards excellence in all things for all  both in academic and Extra Curricular activities.
