Though we do very well academically and our graduates secure places at some of the top universities in the world including Cambridge and Cornell, we understand that this is not the be all and end all. This means being a "family" and not a "factory" as we provide bespoke quality education that brings out the best in every child. As a medium size school its easy to achieve this and small class sizes allows each student to get the attention and support they deserve.
The list of extracurricular activities is extensive allowing students to constantly try new things and develop their passions - we acknowledge that everyone has their own pathways and encourage students to be the best they can in whatever they choose to focus on. These methods of encouragement, support and understanding create a happy community where the relationships and level of care between staff and students always exceed expectation.
We are also both a day and boarding school catering to a large age range - from 3-18.
