Beyond the classroom
The school runs a Platform Pups programme, working with local state primaries to identify bright children who would benefit from Saturday morning stretching sessions. This outreach also feeds into expanding bursary provision, widening access beyond those who can meet the full fees.

Mobile phone policy
(Older) boys who travel to or from school without parents are permitted to bring mobile phones to school. When arriving at school, boys are encouraged to send their parents a text to say that they have arrived safely. They will then be required to turn off their mobile phone (that is powered off rather than screen off) and put their phone into their locker until the end of the school day. Boys may turn their phones on as they are leaving and again, we encourage them to send parents a text to say that they are on their way.
