Bullying is now recognized as a concern in schools worldwide. Bullying is a relatively new study field classified in the category of aggression. A person is being bullied when he or she is exposed repeatedly and over time to negative actions on the part of one or more persons. This study was conducted to acquire types of bullying behaviors and prevalence of bullying among elementary school children. For this purpose, questionnaire of Colorado School Climate Survey (Garrity et al., 2000) was used as a self-report measure to investigate bullying and applied to 1086 elementary school students at Bursa. The results were generally similar to those reported by most international studies of school bullying. The most prevalent form of bullying is verbal bullying and this is followed by the physical bullying. The boys are reported more than girls as bullies. The most likely location for bullying to occur is the playground and classroom.
