St. Mary's Sr. Sec. School is affiliated to the council for Indian School Certificate Examinations (ICSE),New Delhi. The course of study followed in the school is in accordance with the syllabus prescribed by the council. The school prepares its students to qualify for the ICSE examination.

Curriculum plays crucial role in all kinds of education systems. We, at St. Mary's School, firmly believe that meaningful learning is much more than books and lessons and a holistic development is our ultimate aim. We are of the view that whatever a student learns during schooling, influences his or her future and character. We leave no stone unturned in imparting quality education that makes students not only learned but also wise.

The concept-oriented curriculum that we have created at St. Mary's School, prepares students for life not just for exams. Each and every module is designed keeping in view the overall development of the students so that they can come out as responsible citizen of society. We don't just prefer the curriculum that concentrates only on academics but also on the holistic development of the students.
