Teaching ethics in compulsory school regained urgency some years ago in Sweden when National Tests in ethics were introduced. Students were evaluated as having or not having the ethics knowledge required. The aim of this study is to investigate what aspects of ethical competence students express in texts from National Tests, and to investigate what cultural tools 12- and 15-year-old students use in their texts about a given ethical situation. A qualitative content analysis was performed in three steps. In the (...) first step, four aspects of ethical competence were identified: to verbalise, to take a stand, to take responsibility for one’s actions and an understanding of life. In the second step, the identified ethical competence was interpreted through four ethical voices building on the theories of Nussbaum, Løgstrup, Benhabib and Singer, showing that the students’ texts contain varying aspects of ethics. In the third step, cultural tools used by the students were identified. The conclusions were that some ethical perspectives, such as the societal and global perspectives, are disadvantaged in the analysed texts, and accordingly in the tasks;, ethics is a difficult subject to assess in a fair way; and since cultural tools are dependent on the social, cultural and historical context, the school has a responsibility to teach ethics in a way that gives all students the power and authority to live good lives.
