Abstract: Abstract This study investigated Secondary Four students' and teachers' perception of School Based-assessment (SBA) in an English-medium (EMI) secondary school in Hong Kong. The study explored the subjects' perception of SBA and the rationale of their perceptions. The study focused on the two main areas, i.e., SBA as an effective assessment to judge students' oral abilities and enhance teaching and learning. Its effectiveness of motivating students to read extensively was also explored. The study was conducted in 2006 in an EMI secondary school. All the Secondary Four teachers and students of the participating school were involved. In this study, two sets of questionnaires were first administered and interviews were then conducted to obtain information about the subjects' perceptions of SBA. Results from a questionnaire survey and interviews indicated that the subjects (both the teachers and students) did not totally agree that SBA was an effective tool to judge students' oral abilities, enhance teaching and learning and motivate students to read extensively. The findings of the study reveal that the dominance of exam-oriented culture might be the most influential factor which leads to the teachers' and students' negative perception of SBA. Another possible reason is cultural factors involving the availability of resources, teacher's training, work load and time constraint in the Hong Kong context. Recommendations are made to address these issues in order to facilitate the implementation and development of SBA in future.
