The purpose of this review study was to conduct a thematic exploration of prior studies related to the transition between primary and secondary school. The aim of the paper was to discover (1) the extent of earlier research, (2) how earlier research thematises social and emotional issues, and (3) suggestions of those studies concerning how to improve schools. Searches were conducted across four international databases of peer-reviewed research to identify articles published in the last decade on the topic 'transition between primary and secondary school'. Articles related to social and emotional issues were further selected, and thematic analysis was conducted on the selected 29 articles to identify the topical focus. This review study draws attention to the importance of understanding challenges related to the transition between primary and secondary school. Overall, the analysed studies indicate that this is an important focus for educational research. Key issues related to support and wellbeing/bullying have emerged, which clarify the importance of further research in this field. The present study may also contribute to increasing awareness among policy makers and school leaders of the challenges related to the transition between primary and secondary school.
