Extramural activities extend through the normal sports programme, clubs and cultural activities. Priority is given to the development of an individual's particular gifts and talents in an atmosphere which engenders positive growth.
Cricket, rugby, tennis, hockey, soccer, swimming, athletics, cross country and golf are played.

Competition

The three school houses are Carey, Judson and Livingstone; inter-house as well as inter-school competitions provide opportunities to practise life-skills like winning and losing, team participation, goal setting and self-discipline.

Trevertonians regularly pit themselves against teams from Pietermartizburg, the Midlands, and as far afield as Greytown, Estcourt, Winterton and Underberg.

Provincial Representation

Each year a small number of Prep pupils  represent the school at provincial level.
