St. Mary's Education Society was Established on 24th January, 1966 and registered under the Societies Act. St. Mary's School at B - 2 Block, Safdarjung Enclave is around 43 years today. The School is Co-educational, has about 1500 students and is open to all irrespective of caste, community or religion. It is recognized by the Delhi Administration and affiliated to the CBSE. The School's growth has been rapid and its performance remarkable. Today, it stands in the front line in the sphere of education in Delhi.

St. Mary's School has a strong sense of Social Commitment. The School maintains a close relationship with the Spastic School of Northern India and the National Association for the Blind. Normal, Spastic, Blind and the Physically handicapped all study together under an Integrated Education Policy. The School also has a regular literacy programme for the children and women of our adopted basti - Indira Nagar, which includes medical checkup and a daily meal.

Life at St. Mary's is a judicious blend of academic work and extra curricular activities, ranging from a school band to computers and from basketball to drama. Students are expected to participate fully in the life of the school so that they gain from working together. Our aim is to educate students in the fullest sense so that on leaving school they are confident, have the ability to express themselves clearly, have a well developed critical awareness, a sense of social responsibility and a belief in their own worth.
