The aim of this study was to investigate whether, in the Hong Kong context, self- and peer-assessment promote students' self-reflection and enable students to understand their own strengths and weaknesses better. A three-stage assessment strategy was employed in three Science courses at The Chinese University of Hong Kong: (1) students developing assessment criteria, (2) self-assessment, and (3) peer-assessment. These assessment strategies are not common at the University. Education in Hong Kong is often portrayed as having less experience of, and being somewhat resistant to, educational innovation. So, in addition to studying the learning potential of these strategies, the study also focused on the practicality of implementing the new strategies. The results confirm that there are challenges in the present context but also indicate that these innovations to assessment are well perceived by students if they are appropriately framed and implemented.
