Bullies tend to target children who are smaller than they are, as well as quiet children, good pupils and children who are different. A recent survey by the Association for the Psychosocial Health of Children and Adolescents (EPSYPE) found that 25 percent of pupils have experienced some form of verbal, physical or sexual intimidation or violence up to two or three times a month, while 10 percent have used some form of intimidation against their fellow pupils. A lack of communication between pupils and teachers aggravates the phenomenon.
