AbstractLiterature shows that a well-organised and committed whole-school approach in supporting students’ well-being enhances learning and school performance. This study is conducted as part of the school-based action research to examine the effects of a customised group guidance programme in helping students manage their transition from primary to secondary school. The objectives are to facilitate a smooth transition and to assess students’ perceptions of the guidance and counseling unit in the school. The participants of this study involved 320 secondary one students in an all-girl, autonomous school in Singapore. The findings show that 74% of the students experience anxiety despite being in a school of their choice.
