In Nendrum College, all pupils and staff are organised into three Houses: Darragh, Enler and Gillespie.

Gillespie House is named after Sir Robert Rollo Gillespie, who fought against the French and was killed while attempting to storm the fortress of Kalunga in Nepal in 1814. His reputed last words were "One shot more for the honour of Down". A statue of Gillespie can be seen in Comber Town Square.

The Enler River originates in the Holywood & Castlereagh Hills. From there it flows through Dundonald and on into Comber, before finally entering Strangford Lough at Island Hill on Comber Estuary. The river runs along the back of the school and is famed for producing beautiful, hard-fighting sea trout and brown trout that will test an angler's skill to the fullest.

Comar, which means "meeting place of the waters" was the name given by the ancients to a settlement at the northwest corner of Strangford Lough at the confluence of the Enler and Glen Rivers. Today we call it Comber, famous for its spuds. Darragh House takes it's name from the road/area the school was built in.

House points are awarded for a wide range of school activities, for example:

This is not an exhaustive list and points may be awarded at any time by staff as and when appropriate.
