Primary–secondary school transitions are widely recognised as pivotal developmental periods, which can have positive and negative longitudinal implications on the education, wellbeing and mental health of children. Yet few studies have sought the voice of children through interviews, and especially children in receipt of pupil premium funding (PPF) (a government grant given to schools in England to support disadvantaged pupils from low socio‐economic status [SES] backgrounds). This is concerning, given that children who receive PPF are at greater risk of poorer academic, social and emotional outcomes and exclusion during this time. Our study aims to explore the perspectives of such children to better understand their lived experience of primary–secondary school transitions. The sample consisted of nine Year 6 (last year of primary school in England) children who received PPF, recruited from two schools in Greater Manchester. The children participated in semi‐structured Zoom interviews. Transcribed audio‐recordings were analysed using reflexive thematic analysis. The children discussed a mixture of contrasting feelings towards the emotional, social, academic and practical aspects of primary–secondary school transitions. In addition, children highlighted the supportive value of having older siblings, cousins and friends already at secondary school and discussed the range of support that had been offered by their schools and how this could be improved. The study makes a unique empirical contribution to understanding the lived experiences of children in receipt of PPF leading up to primary–secondary school transitions. In doing so, we make a unique theoretical contribution to multiple and multi‐dimensional transitions theory in exploring the impact of wider social factors, such as SES, on primary–secondary school transitions experiences. This understanding has important implications for educational policy and practice, in addition to further research, especially given the methodological, theoretical and conceptual considerations discussed.
