The school is constituted by plural bodies, but genders and sexualities are lived individually, indicating that what applies to the essence of the human being also applies to bodies. This study addresses the limits and possibilities of bodies at school, in view of the violence present in disciplinary practices upon the bodies. In addition, bodies and their sexualities, when experienced outside the preestablished standards of today's society, are not binary. The methodological path begins with direct observation in schools, lectures and identification of approaches to the themes by teachers, followed by a more in-depth bibliographic review. Finally, it appears that schools and teachers opt for the biological approach of the body, for a concealment of sexualities and for a certain indifference toward the gender approaches, often due to ignorance, lack of interest or because of moral values or religious.
