The article describes a new method for assessing the risk of bullying at school. We present certain results of international studies in the area of school bullying. We outline the reasons why it is necessary to develop assessment tools and school bullying prevention programs in Russia. We describe the process of developing, testing, and validating a methodology for assessing the risk of school bullying among schoolchildren. The sample consisted of 285 adolescents (53 percent girls) between the ages of 10 and 18. We demonstrate the underlying four-factor structure of the survey, which provides an optimal fit for the empirical data and includes insecurity, wellbeing, disunity, and equality scales.
