While significant progress has been made on understanding the effects of student self-assessment, the processes by which these effects occur are much less studied. The present research identified the actions involved in a cyclical self-assessment process. In this qualitative study, 17 undergraduate students from a teacher education institute took part in in-depth interviews focusing on the common actions students normally undertake to self-assess. The findings identified the following three actions that are commonly undertaken in the self-assessment process: (1) determining the performance criteria, (2) self-directed feedback seeking and (3) self-reflection. The paper discusses the implications of the findings and concludes with suggestions for promoting student self-assessment.
