The Foundation of COSA - Cluny Old Students' Association was laid in the early 1960's under the guidance of Rev. Mother Laurence who was the Superior then. It was one way of keeping ties with the Alma Mater who had done so much for the school in the vital years of its life.
Since then, COSA has been functioning with the guidance and co-operation of the Principals and Teachers through the years and now it boasts of hundreds of life members. Our members are old students from all walks of life and some have made a big name and done the school proud.
The COSA functions in a uniform pattern throughout the year. The year's activities start with a get together and welcome to the batch that passes out currently. The year's activities are also chalked out, like holding various debates, competitions, food fest, giving scholarships etc. The aim of COSA has always been to work for the welfare of the school and hence the programs are planned accordingly.
What COSA has been doing for the school is of little relevance when compared to what the school has been doing for its students - in molding the character and teaching principles of a disciplined and simple life. COSA opens its membership to all past pupils.
