School bullying is quite common in most schools. According to the American Psychological Association, approximately 40% to 80% of school-age children experience bullying at some point during their school careers. Regardless of the grade level, socioeconomic environment, gender and religion, bullying can happen to anyone. Teachers need to have a certain level of awareness of this issue. This starts with understanding the three forms of bullying: physical, verbal and emotional. Physical bullying is any unwanted physical contact between the bully and the victim. It is the most identifiable form of all. Verbal bullying is any injurious language or statement that causes the victim's emotional suffering. Emotional bullying is any form of bullying that causes damages to a victim's emotional well-being. The consequence of school bullying might be horrible. It is a major cause of school shootings. School shooters that died or committed suicide left behind evidence that they had been bullied. Therefore, enough attention should be given and practical measures should be taken by the school administration to address this issue.
