A sophisticated state-of-the-art computer lab with 175 computers, uninterrupted power supply, stand-by generator and round-the-clock internet facility is the pride of the St. Thomas. All the teachers are computer literate and have undergone "Intel Teach to the Future" programme. Technology-aided teaching is effectively carried out using an LCD Projector in an air-conditioned Audio Visual room. The prestigious Computer Literacy Excellence Award at the state and national levels conferred on the school in 2002 raises it to the position of the nation's best in modern technology.
