History of the school
St Thomas’ School, founded in the year 1789 for the English speaking community of Calcutta, is the oldest school in West Bengal and the second oldest in India. It traces its direct antecedents back to 1729 as the Charity School. Originally called The Calcutta Free School when it first started in 1789, it provided free education with complete hostel facilities for indigent and orphan Anglo-Indian boys and girls. The original

property on what was then The Calcutta Free School was given up in exchange for the present campus of over 20 acres which was once the residence of Warren Hastings, the Governor-General of India. This exchange of property was subsequently codified in The Bengal Act XII of 1923, as also the composition of the Board of Governors and the aims of the Institution. This school is unique in that it is the only known school to be guided by an act of Government.

The President of India is the traditional Patron and its affairs are controlled by a strong and influential Board of Governors as determined by the St Thomas’ Schools Act of 1923. His Grace, the Bishop of Calcutta, is the Chairman of the Board of Governors. The Master of the Calcutta Traders Association is also an ex-officio member. The Board has representatives from the Government of West Bengal, the Bengal Chambers of Commerce, the Anglo-Indian Association, the Vestries of St Paul’s Cathedral, St John’s Church and St Stephen’s Church. There are five co-opted members which include elected representative of the teaching staff.

Within the statutory framework of the St Thomas’ Board of Governors, the School is administered in its day-to-day affairs by the Principal of the Boys’ School who is assisted by the Vice Principal and the Head of Junior Department (classes 1-5).

School anthem
We are proud of St Thomas and her colours in blue And our banner is proudly unfurled Our motto it teaches a lesson so true Count’ring evil and self and the world We have pledged to be loyal and to stand side by side And to give of our best is our aim If we win or we lose, you may count on the ‘Blues’ Being cheerful and playing the game.

We must always try hard be at work or at play And uphold what is noble and true Let us each pass the torch at the close of our stay Ever keeping the flame steady through With the oldest of schools and the greater ones too We can boast of achievements as fine Let us strive for fresh honours and records good few That will hold high our aim sublime.

Though the years of our stay shall be left far behind Naught will sever the link with our school And we’ll join with those pupils whom then we shall find And our ties with them gratefully pool Present pupils and past, come sing loud in her praise And her glories let’s proudly reveal And our prayers with sincerity earnestly raise For her future success and her weal.
