English: This article offers a perspective on the topic from educational psychology, with a focus on adolescents, who often air their frustrations at growing up and developing their own unique identity by way of opposition. The literature suggests that aggressive behaviour correlates with the social environment and reaches higher levels in lower socio-economic environments. The purpose of this research was to determine teachers’ experiences of aggressive adolescent behaviour at a privileged school and to provide guidelines for dealing effectively with it. A qualitative research approach was chosen. By means of analyses of the transcribed interviews central themes could be identified, and recommendations made.
