The aim of this paper was to report and discuss a study in which 15-year-old pupils and their teachers at a Swedish multi-cultural school described that values were mediated in the classroom. The study was a case study and the method used was focus group dialogues. Five dialogues were performed with all (42) teachers at the school and fourteen dialogues with ca 50% (76) of all 15-year-old pupils at the school. The result was that pupils and teachers agreed that values were mediated in different ways; differences between the pupil and the teacher groups were that the pupils described that values were mediated mainly by teachers telling them what was right and what was wrong, whereas the teachers described that values were mainly mediated by teachers listening to the pupils and showing them confidence. The result was discussed in relation to European goals of school development and sustainable development.
