The present study investigated the degree of congruence between student self-reports and teacher reports of relational and physical victimization and tested whether gender and age moderated these relations. Mixed effect regression models were conducted on a sample of 294 students (50.7% male) in Grades 2 to 5 and their classroom teachers. Results revealed that, despite its covert nature, greater agreement was found between students and teachers on reported rates of relational victimization. However, contrary to our expectations, teacher and student reports of physical victimization were unrelated. Greater agreement was also found among girls and teachers as well as between older students and teachers, however, on reported rates of relational victimization only. Implications are discussed in light of school-based intervention efforts to address peer victimization among students.
