The School is divided into Four vertically arranged Houses of approximately 120 students and 9 staff. From 2004 the college placed a greater significance on the role of Houses with each functioning like a mini school, complete with a Head (House Dean) and assistant teachers, Student leader (House Captain) and student leaders for various activities. Boys stay with the House they are allocated for their time at Lindisfarne giving continuity and a sense of belonging. The main purpose of Houses are for inter-house competition in a variety of activities. Staff have a responsibility to support the House Dean in organising inter-house activities, with the students given leadership opportunities where possible. Houses are also used as a means of taking a accurate roll during emergency procedures and staff assistance of the House Dean is essential on these occasions. Students from year 7 to 10 are placed in Horizontal form classes while those in year 11 to 13 are placed in vertical mentor groups and remain in this group for their time in the senior school. These mentor groups are formed from students in the same house and they retain the same mentor teacher each year in order to maintain continuity.
