In order to investigate school culture and classroom psychosocial climate as one of its components, Classroom Psychosocial Climate Questionnaire (Fraser et al, 1995) was administered to 415 (217 male and 198 female) junior high school students. The scale consisted of four subscales, including friction, cohesion, task-orientation, and competition. the results showed that the total scores of female participants on the. scale were significantly higher than males. There was no significant interaction between students" gender and grade level in terms of their total scores. Classes with first graders were more coherent than third graders, and there was no significant difference between other grade levels. While, in competition and friction subscales, boys scored higher than girls, in cohesion and task-orientation subscales the difference was reversed. In the final section of the article, findings are disscussed in the light of related literature and suggestions for further research are set forth.
