In Chile, education policies of accountability, associated with the judicialization of school life, have involved the management of violence and school coexistence, generating punitive policy environment by means of threat of sanctions. The Superintendency of Education, a State agency responsible for overseeing regulations, also has a device that allows parents to report actions of harassment against their children/pupils. This study examined, through a critical analysis of the discourse, 30 response records prepared by schools during 2018 after receiving a complaint. The results show the construction of discourses that establish the school as an educational court and the student as a problem, using mechanisms of behavioral hypervigilance. We discuss implications of the installation of this device which has strengthened the judicialization of conflicts related to coexistence, in a particular conservative mode whereby schools - and sometimes the principal - is both judge and party.
