At St. Columba's the "youth" of the congregation include those between the ages of thirteen and eighteen. Youth classes and programmes provide students opportunities for education, service and fellowship.
The Senior Study Group is a classed designed for this age group that meets weekly during Sunday worship beginning after the scripture readings. The group leaves with their teacher and usually meets in the blue room for fellowship, Bible-based study, and current issues discussions. In addition, events scheduled outside class time involve opportunities for serving and socializing.
