Human beings are exposed to learning that can affect them positively or negatively throughout their lives. In the case of aggressive behaviour, it is considered harmful to human integrity and to society in general, which is why early attention to this scourge is necessary in order to stop the damage caused by it in a timely manner. The school is the first educational centre where the individual is sheltered from childhood, becoming the main space for intervention to reduce the aggressive behaviours with which children arrive at these educational institutions.
