International and national studies have revealed a sharp decline in student science engagement during the middle years of schooling. In Aotearoa New Zealand, over 20 years of cross-sectional evidence has repeatedly shown high levels of student engagement with science in primary school and lower levels in high school, but very little evidence in-between. In this study, we conducted an engagement survey (n = 429) across Years 7-10 (11-15 yo) to better understand this gap. We found that decreasing engagement with science was only apparent when considering school science, but not in other contexts like choosing science careers or science outside of school. Contrary to common rhetoric of a 'decline' in student engagement with science, we suggest that the middle years are marked with uncertainty about the role of science in students' lives, which would benefit from a shift toward contextualised curricula.
