This research study explores the assessment practices in two higher education art and design departments. The key aim of this research was to explore art and design studio assessment practices as lived and experienced by art and design lecturers. This work draws on two bodies of pre-existing research. Firstly this study adopted methodological approaches that have been employed to good effect to explore assessment in text based subjects (think aloud) and moderation mark agreement (observation). Secondly the study builds on existing research into the assessment of creative practice. By applying thinking aloud methodologies in a creative practice assessment context the authors seek to illuminate the "in practice", rather than espoused, assessment approaches adopted. The analysis suggests that lecturers in the study employed three macro conceptions of quality to support the judgement process, namely the demonstration of significant learning over time, the demonstration of effective studentship and the presentation of meaningful art/design work.
