The far-reaching impacts of the teacher-child relationship, including academic achievement and social/behavioral adjustment, have been well-documented. At the same time, literature also suggests that teacher perceptions of teacher-child relationships are impacted by the race/ethnicity match or mismatch between teacher and child, with matching related to more positive teacher perceptions. However, limited work has focused on children who are at-risk for emotional and behavioral disorders (EBDs) or tested the mechanisms that mediate the relation between a mismatch in the race and teacherperceived conflict. Thus, the current study used multilevel structural equation modeling to test whether a higher proportion of race mismatch between children in the classroom with problem behavior and teachers was related to teachers' classroom management self-efficacy and, in turn, teacherperceived conflict with children among 148 teachers and 354 preschool-aged children. Results indicated that among students most at-risk for EBDs, a higher proportion of race mismatch between teachers and children significantly predicted less teacher classroom management self-efficacy and, in turn, significantly predicted teachers' greater perceived conflict with children. Furthermore, this mediation pathway was significant.
