St. Thomas' College designs and implements its own curriculum and tries to ensure that the students and the teachers have as much flexibility as possible to foster true learning in a child. St. Thomas' College is affiliated to the Council for the Indian School Certificate Examination (CISCE). English is the medium of instruction, and the Council administers two public examinations - The Indian Certificate of Secondary Education (ICSE) at the end of year X and, subsequently, the Indian School Certificate (ISC) at the end of year XII. Both examinations are held annually in March.
Within the CISCE syllabi, St. Thomas' College ensures that flexibility of methodology and the use of experiential learning system is strongly encouraged, which help eliminate the need to learn by rote and develop a healthy and positive attitude towards learning. Our system of evaluation takes into account the individualities of different children to provide adequate feedback on the students learning without putting undue pressure. As the child progresses through the classes, the assessment is gradually modified to prepare the students for external tests and competitive exams.
