The pedagogues’ own use of language affects how perceptions, norms and categorizations are conveyed to the pupils. They also points to their insufficient knowledge of intellectual disabilities. This lack of knowledge also affects how the pedagogues view the institutional striving towards student inclusion in a “school for everyone.” The study also shows that a norm critical perspective is preferable as it allows for perceptions, norms and categorizations to be made visible. The study showed that, in order to avoid unfavorable categorizations and norms, a communicative environment is needed in order to create an understanding in regards to the individual differences that exist between students in the school environment. This essay illuminates the fact that pedagogues – working with children with intellectual disabilities – are affected by the perceptions, norms and categorizations of society.
