This study investigated children's and adolescents' reasoning about intergroup exclusion based on social class from educational opportunities in Türkiye. The role of children's and adolescents' perceived contact with friends from different socioeconomic backgrounds on their evaluations of exclusion and personal solutions to the exclusion was also examined. Participants (N = 270) included 142 children (8-10 years old, M[subscript age] = 9.80; SD = 0.82; 53.5% girls) and 128 adolescents (14-16 years old, M[subscript age] = 15.46; SD = 0.91, 61.7% girls) from lower (N = 144) and higher (N = 126) socioeconomic backgrounds. Results showed that while most participants viewed social class-based exclusion as wrong, adolescents were more likely to view it as wrong than were children. Adolescents from lower SES approached social class-based exclusion as less acceptable than did adolescents from higher SES who referred to expectations about conformity to authority and the status quo. Moderation analyses showed that for adolescents from higher SES, higher perceived contact with friends from lower SES was associated with decreased acceptability of exclusion and increased motivation to provide equity.
