The spirit of St. Charles High School is symbolically expressed in its emblem. It is nothing but the spirit of the life of St. Charles lived out in the 15th century in total commitment and faithfulness to the will of God. The same spirit has been passed on to us down the ages and well depicted in the Coat of Arms.
The centre of the emblem is occupied with the Shield. The colour blue depicts the colour of the mantle of Mother Mary, Mother of Jesus. The red colour on the Shield chatecterizes the loving heart of Jesus and his sacrifice for the redemption of humankind. The golden beehive is flanked by bees of golden hue on either side. Above these are found letters S.C.B (ST. CHARLES BORROMEO) in silver, entwined with a golden chord. The whole Shield is surrounded by lilies and violets, in the midst of which is our motto 'Toil, Faith and Progress'. The entire crest is surmounted by a cross radiating the divine rays and the warmth of divine love. The beehive represents every institution of St. Charles inhabited by busy bees - all working together for the common goal.
