Aggression refers to causing damage or injury to things or other individuals with the intention of causing damage, or injuring another person. Various factors affect the risk of developing aggressive behavior in adolescents, so risky ones increase it, and protective ones decrease it. At the same time, these factors do not occur only in the family and at school, but include all the levels in which the adolescent is and his personality traits. When it comes to the school environment, the risk and protective factors are related to the school climate, the influence of the teachers who teach at the school, the attitude towards peers, the quality of the school, academic success, etc. The school as an educational institution has the responsibility to react preventively in order to prevent aggressive behavior and other behavioral problems. Professional associates employed in schools, including pedagogues, participate in preventive activities. They use a variety of strategies for this purpose, including assessing the likelihood of behavioral problems in adolescents and taking steps to prevent behavioral problems during individual and group activities, as well as during workshops. Likewise, pedagogues are focused on fostering emotional intelligence in students through acquiring social skills, collaborating with parents, consulting with teachers and other professionals, and fostering a positive school environment to prevent behavioral problems among youth.
