Assuming that the quality of assessment for learning (AfL) is, to some extent, bound by the context of the assessment culture it thrives in, it becomes important to understand students' experiences of the cultural characteristics that are regarded as valuable for their learning. The purpose of this study is to explore and compare students' experiences of assessment practices in schools with an overt policy of AfL implementation with those of students in schools with no AfL policy. Focus group interviews with students were conducted in three Icelandic upper secondary schools. The findings show that students value positive teacher-student relationships and active dialogue with teachers.
