This study investigates socially dominant adolescents: students who are actively involved in establishing peer norms, influence their classmates' opinions, and are often the center of attention. Data from 5,468 seventh graders (M age = 13.3; 53% girls) in 266 classrooms were used to examine how social dominance relates to achievement, peer acceptance and rejection, self-perception, and deviance and to investigate contextual moderators of these associations. Multilevel analyses confirmed social dominance to be associated with both positive and negative adjustment. Moreover, the associations with achievement and disruptive behavior were moderated by the normativeness of these behaviors within the classroom. Finally, latent profile analyses revealed 4 distinct types of highly dominant students, 2 well adjusted and 2 poorly adjusted.
