Method: The present study is going to be based on research developed according to the method of deductive approach, historical and comparative procedure and interpretive, exegetical, systematic and critical legal explanation, which is going to be based on national and foreign bibliographic research. Results: As a result, it was found that the existence of a national policy that conceptualizes and characterizes systematic intimidation (Bullying and Cyberbullying), which classifies the social phenomenon and promotes training campaigns for teachers and pedagogical teams and provides guidance to them is fundamental. However, the aforementioned public policy has gaps with regard to the form of treatment that should be given to the violence practiced, as well as to the victim and to those who practice cyberbullying in the school environment.
