The House system is an important part of school life. Each girl belongs to one of three Houses – Arundel, Balmoral and Caernarvon. There are a number of competitions across the year in which the girls compete against each other while representing their House. These contests may vary each term, but recent battles have been a House quiz, a cake decorating contest and a hanging mobile design competition. The year culminates in a Key Stage 2 House Swimming Gala and Sports Day, in which all pupils from both the Boys’ and Girls' Prep Schools participate.
Each House is led by a member of staff and a House Captain and Deputy chosen by the pupils. The Year 6 girls are given the opportunity to put themselves forward as the most eligible candidates to lead their House to victory. Voting takes place each September and the elected captains are responsible for leading their House for the rest of the year. Throughout each term, all the girls in the School are keen to receive House points that go towards the weekly totals. On an individual basis, girls also receive awards of bronze, silver, gold and platinum to celebrate their hard work and exemplary behaviour.
