As a Christian School Calvin is committed to knowing and caring about every student and Old Scholar. COSA – Calvin’s Old Scholars Association, provides a wonderful way for old scholars to keep in touch with the school community.



Calvin values the active interest and involvement of their past students and encourages them through the Calvin Old Scholars Association (COSA) to maintain their links with the school.

In 2005 the Calvin Old Scholars Association (COSA) was formed to celebrate the 30th anniversary of secondary education at Calvin

There are a number of COSA activities organized each year.  These activities provide a dynamic link between the school and the broader community, allowing for regular contact between Calvin graduates.  COSA play an important role in supporting, encouraging and mentoring students.


Invariably reunions are one of the most popular activities of a COSA group.  The opportunity to catch up with ‘old’ friends, renew acquaintances and enjoy the company of those with whom we journeyed through school are wonderful times of celebration. Discovering how people have changed is also a delight as new futures and friendships are formed.

In Touch

In Touch is the official Calvin Old Scholars newsletter. Old scholars are warmly invited to share their news in the ‘InTouch’ publication. The newsletter is published three times a year. Copies of InTouch and Old Scholars news items can be found HERE.
