The rector of St. Mark's is a member of a team of chaplains who minister to the staff and pupils of Duncanrig High School. This involves providing a 'Hot Chocolate' club in the nurture room on Tuesday Lunches, being with a fruit-juice cocktail bar during the primary schools visits, coffee and cakes on occasion staff in-service days and seasonal assemblies. The rector also runs a after-school games club which, through various contacts, made it possible for the rector to speak about the Scottish Episcopal Church and display vestments and communion vessels, bibles and hymn books and liturgies to several classes investigating different religions and forms of worship.
