Matric Farewell
The Grade 12 learners are resposible for the financing of the Matric Farewell themselves.  Funds are generated by way of the Ladies Night, Senior Ball, Civvie Day and Stellie Stars.  

Fashion Show
The annual matric fashion show commences the day after the matric farewell. This is an opportunity for the participating matric learners to showcase their elegant gowns and stylish suits to parents and curious onlookers. The initiative makes all the glamour and glitz of the evening accessible to all those who missed the event and prolongs the good memories of the night before for the participants. The show also doubles as a fundraiser for Stellenberg Netball.

Senior Ball
The Senior Ball is attended by grade 10-12 learners only. This event is coordinated by Mrs E. Carstens and the Matric Parent Committee.

Sjampanjenooi
The Sjampanje-nooi competition is an annual event where Stellenberg's fairest show their flair.

Ladies Night
This is a Grade 12 fundraising project to collect money for the matric farewell. It entails a posh evening for mothers and daughters with a guest speaker.

Stellies Stars 
Stellies got Talent is an annual talent competition, designed to showcase the incredible variety of talented learners from Stellenberg High School. 
From 2012, Stellenberg High School will be hosting its very own Glee Club, based on the immensely popular television series "Glee".

Exchange
As the name indicates, an exchange programme is a project where a learner acts as a host to an overseas learner who then in future acts as a host when our learner visits him / her.

To date our guests from Linz, Austria have visited us every second year. They were welcomed with typical South African hospitality and taken on daily interesting outings in the Cape Peninsula. At the homes of our learners they experienced South African cuisine and socialised with many other learners from Stellenberg High School.
In return our learners visit the Linz International School in Austria and experience the best Austria has to offer. It is an experience that enriches our learners on all levels.
