The badge consists of two motifs in silver against a background of plum and green.

The primary motif is an ancient chair symbolizing the acquisition and transference of knowledge.
The second motif of a crenellated castle can be historically related to the origin of the farm Stellenburg.

Together the two symbols represent:
The intellectual preparedness of those who possess knowledge and the ability to think dynamically.

The primary function of the school as a safe stronghold for the promotion of intellectual, spiritual and physical development.
