The extent to which teachers make changes in classroom seating reflects, in part, the degree to which they value promoting positive peer relationships in the classroom. We assessed the frequency with which teachers made both minor (i.e., involving only 2–3 students) and major (involving half or more students in the class) changes in classroom seating. We tested whether the frequency of seating changes was linked to teachers’ beliefs about promoting positive peer relationships, their attunement to child- or peer-reports of peer victimization, and their concern about bullying at the school. Participants were 37 fourth-grade teachers and their students (N = 677). The frequency of major seating changes was negatively associated with teachers’ peer-focused classroom seating (PFCS) beliefs and to their attunement to student peer victimization. Minor seating changes were positively associated with PFCS beliefs for teachers with low or average attunement to peer victimization; however, teachers highly attuned to peer victimization made fewer minor seating changes regardless of their PFCS beliefs. Implications for research and practice are discussed.
