This text, which is part of the field of Cultural Studies, aims to analyse the ways in which the book of chronicles The Efficiency of Disability acts pedagogically towards people who live with people with Down's Syndrome and how this book represents the identity of the special dancer. The main aim of this study is to show how the special dancer is represented through a normalised identity in the narratives and how the book A Eficiência na deficiência acts in people's lives as a cultural pedagogy.

The methodology is based on bibliographical research using the book Efficiency in Disability and theoretical texts dealing with representation, identity, disability, efficiency and cultural pedagogies.
