Bullying has been a recurrent phenomenon throughout the history of education. Among those most vulnerable are those with intellectual disabilities who tend to suffer greater levels of victimisation. The purpose of this research is to analyse the prevalence of bullying of students with intellectual disability in ordinary schools compared to special education schools. The project used a nonexperimental, descriptive and correlational methodology with a sample of 99 students who completed the validated European Bellying Intervention Project Questionnaire measurement tool. The results show that the majority of students who were victimised by bullies left their ordinary school during secondary education. Within ordinary schools, students with disabilities are more likely to experience bullying in the role of victim while in special education schools the most frequent role is that of observer.
