The aim of the school is not merely the academic education of the student. One of the earliest findings of the UNICEF is that the existing conventional system or education cannot cope with the needs of the nation. The development of the nation ultimately depends upon the system of education adopted. Man and women who possess knowledge, morality, intelligence, work experience and productive capacity are the nation’s best citizens.  Learning for earning is postponed to a later stage. The main characteristic of the new thinking of education is that learning of KNOWLEDGE and learning to BE should go concurrently. "The main purpose of education” says Hubert Spencer “is not knowledge but Action". As a practical approach to this revolutionary theory the St. Marys Educational and Cultural Society, Thiruvalla, has adopted the 10+2 pattern of the Central Board of Secondary Education, New Delhi for the formation of the child to an upright citizen.
