The aim in Boarding is to foster a supportive and caring community for students from Year 4 to Year 13, where the students value belonging to a wider family. Boarders learn how to live, to work, to take on responsibility, and socialise in an internationally diverse community.

Since its foundation, Boarding has been an integral part of life at the school. Approximately 20% of Secondary students are boarders. Houses located at the heart of the campus provide an excellent standard of accommodation, as well as easy access to educational and sporting facilities. Boarding life is complemented by supervised study and weekend activities programmes.
