Abstract
Increasing migration and the resultant multiculturalism in Greek society has highlighted the importance of studying the role of school ethnic composition in bullying and peer victimisation, not least because ethnic minority students involved in bullying behaviours seem to experience high levels of internalising and externalising problems. It is imperative that schools work towards ensuring a safe environment for all students. This can be achieved through the implementation of policies that facilitate positive social interactions and address issues of bias-based bullying, thus contributing to social justice. This article examines school bullying and related policies in Greece in the context of increasing diversity and reviews their evolution in the past decade.
