The Convent of Jesus and Mary Old Students' Association (CJMOSA) was initiated by Rev. Mother De Sales in 1965 to enhance togetherness between the Ex-Students and the school, to the mutual advantage of both. It was formed into a regular body by Rev. Sr. Dorothy in 1971 when it held its first meeting. The Association was firmly established under Rev. Sr. Raphael's guidance along with Mrs. Parambi.
