Abstract
This study investigated the prevalence of bullying behaviour among the pupils and the teachers' management of bullying behaviour among the pupils. The study adopted a descriptive survey research design in which 60 teachers from 20 primary schools in the Ido Local Government Area of Oyo State were selected using a multi-stage sampling procedure. Data were collected using a self-designed and validated questionnaire titled Teachers Perception of Prevalence and Management of Bullying Questionnaire. The prevalence of bullying behaviour among the pupils in the LGA was high. There was no significant difference between public and private school teachers in their perception of the prevalence of bullying behaviour among primary school pupils . There was no significant difference between public and private school teachers in the methods and strategies adopted to manage bullying behaviour among primary school pupils. The teacher identifies teacher-parent collaboration as one of the strategies for managing bullying behaviour. It was recommended that primary schools be designed to build a safer, more welcoming and open climate for every pupil. This can be achieved through in-service training for the teachers on managing bullying behaviour.
