The Christian Union is primarily a place for pupils who have an interest in the Christian faith, or hold a Christian belief, to meet regularly within the School. It is therefore not exclusively for Christians, and those of any or no faith are welcome.
S6 pupils organise the events, speakers and activities held throughout the year. Speakers range from Christian youth workers from various local churches, Scripture Union workers, musicians and church ministers. The pupils also hold a prayer meeting each Wednesday morning before lessons.
