Numerous studies have examined the phenomenon of bullying. The development of information and communications technology (ICT) has enabled an emerging form of bullying known as cyberbullying. This article presents a case study of an Internet-focused bullying prevention programme in a Spanish secondary school with 627 students, from a non-experimental, qualitative perspective. The data collected show an ICT-centric institutional framework that supports bullying prevention programmes. The results also indicate an institutional culture highly adapted to ICT based on teleological, psycho-pedagogical, administrative and community dimensions. This culture has favoured the development of the cyberbullying prevention programme studied in this article.
