Mobile phone policy
A clear mobile phone policy is a really important part of modern schooling. This school has provided us with their policy.
Mobile phone policy
Electronic devices (including but not limited to mobile phones, iPads, and laptops) may only be used during the school day if permission has been given by a staff member. Grades 9-12 students may use their mobile phones only during break and scheduled lunchtime. However, the use of technology is not permitted in the dining hall, and mobile phones are not permitted in the library. Grades 6-8 students must hand in their mobile phones to reception as they arrive in the morning. Grades 9-12 students are encouraged to hand in their phones at the start of the day or keep them locked in their locker/boarding room.

Money matters
Expensive, even in comparison to other fee-paying schools in this affluent area of London. ‘Is it worth the money? Absolutely,’ say parents, noting the individual attention, superb quality of learning, the clubs and ‘that beautiful campus’. A dozen
