This study addressed the moderating role of classroom descriptive norms for overt and relational aggression, social withdrawal, prosocial behavior, and academic reputation in the association of behavior with social preference and popularity in early adolescence. Participants were 1,492 fifth-grade students ([x-bar][subscript age] = 10.6 years, 52.7% boys) from 59 classrooms who completed unlimited peer nominations for status and behavior. Classroom descriptive norms were computed as the average proportion of classroom nominations received for the different social behaviors. Multilevel analyses revealed that the negative association between overt aggression and social preference was attenuated in classrooms with high norms for overt aggression. The negative association between academic reputation and social preference was enhanced in classrooms with high norms for academic reputation. Classroom norms did not moderate the associations between behavior and popularity. The type of behavior and the type of status should be considered when examining classroom descriptive norms and behavior-status associations.
