Group assessment now plays a significant role in higher education. Existing researchhas identified a number of benefits that derive from group assessment including the development of generic skills and the promotion of deeper learning. Despite its importance as a learning tool, there has been little research reported in the accounting literature, which has examined accounting students’ attitudes towards the use of group assessment. This paper attempts to address this deficiency by exploring students’ attitudes to the use of group assessment, in terms of group dynamics and generic skills development, in a cooperative learning environment within a final year undergraduate accounting module. In addition, the study analyses students’ attitudes to maintaining a journal or learning log, which recorded the group’s experience of completing the group assessment. Specifically, the study considers whether students’ attitudes differ according to academic ability and it proffers explanations for the findings.
