Bullying in schools, especially in the most preferred secondary schools e.g. Federal Government Colleges and reputable Mission schools, need to be researched into Bullying has effect both on the bully and the bullied. This research therefore investigated the prevalence of bullying among the “most preferred” secondary schools in South - East of Nigeria, focusing on boys only mission schools; girls only Federal schools and mixed (Boys and Girls) Federal school. The purposive sampling method was used to select six secondary schools in the South - East of Nigeria. A sample of three hundred and seven (307) students were randomly selected from the six schools. The research instrument used was the structured questionnaire with reliability co-efficient of 0.72.
