This guide provides information about aggression and its development during childhood and adolescence. It introduces bullying as a subset of aggressive behaviour, highlights research on the nature and extent of bullying in schools and outlines some of the characteristics of children involved in bullying. It helpfully suggests common signs of bullying that Parents and practitioners need to be aware of and offers interventions and resources for those dealing with this behaviour.
