This qualitative case study investigates student and school staff perceptions of transitions and changing social dynamics due to a temporary closure of an elementary school undergoing redesign in an inner-city neighbourhood in Toronto, Canada. Focus groups and interviews were conducted with 75 students (Kindergarten to Grade 8) and 28 staff who transitioned to two neighbouring schools during the school closure in 2011 and 2012. Students reported changes in their sense of belonging, incidents of bullying and violence, and student-student and student-teacher social dynamics during the transitional period. School staff also reported changing social dynamics among staff and students, the importance of strong leadership and teacher support during transitions and changes to school climate as a result of the transition. Suggestions and recommendations for future transitions associated with school redesign are discussed.
