This article reviews literature on whole-school approaches to behaviour management in order to address these questions: How is a whole-school approach to behaviour management defined in the literature? What are the key principles that make a whole-school approach effective? What are the key systems that make a whole-school approach effective? Is the involvement of students an important aspect of a whole-school approach? The review highlights current work on belonging, which shows that a person's sense of belonging has an impact on their engagement and therefore achievement in a school setting. For a whole-school approach to be effective it must have a positive impact on the engagement of the students. The findings of this review suggest that schools implementing a whole-school approach must first examine the quality of the relationships within their school as these have an impact on students' experiences of belonging. The principles and values about relationships that a school holds will shape the kind of whole-school approach they develop.
