There are 4 Houses in St Dunstan's school. There is a strong House ethos in school where all strive to do the best for their House, whether it is collecting money for the House Charity, collecting Housepoints, taking part in house competitions or just wearing the house badge with pride.

Each tutor group is in a certain house, and stays together with their tutor for their whole time at St Dunstan’s. It is very much a family ethos with an emphasis on support for all.

The four Houses are named after local Geographical features and have a distinct ethos. These Houses are:

Blackdown House

Mendip House

Quantock House

Exmoor House
