St Mary's College has a vertical Pastoral system under the current system of four houses.
Mentor groups are at the heart of our pastoral system. To ensure students' individual needs are met, each House is divided into mentor groups comprising of approximately 20 students. Students remain in the same group with their mentor teacher throughout their schooling at St Mary's, offering continued support and guidance throughout their journey. The relationships within each group are unique yet all groups exemplify a familial quality where our older students also mentor the younger boys in their group.
