School Anthem

Truth is our goal

Press on with your might

St Thomas turns darkness to light

With God in our souls

Injustice we will fight

And put all evil to flight

Thamaso Maa Jyothir Gamaya Asatomaa Sat Gamaya (2)

With passion for our nation

Good values we uphold

All people and all race we'll enfold

Irrespective of station

We stand all bold

Never stooping for charm silver or gold

Thamaso Maa Jyothir Gamaya Asatomaa Sat Gamaya (2)

We love our Alma mater

St Thomas our home

Anger and vice here will not roam

O God! there is none greater

We serve Thee at Thy Throne

With Thee we are ne'er alone

Thamaso Maa Jyothir Gamaya Asatomaa Sat Gamaya (2)
