The concept of 'pedagogic voice' emphasises the capacity of children to express their views on matters related to teaching, learning and curriculum. 'Pedagogic voice' aligns with children's rights to be listened to and the extent to which their views are fully considered and acted upon. Combined, these rights based approaches positively shape children's learning experiences. This paper draws on quantitative and qualitative data from the longitudinal mixed methods cohort study Children's School Lives to explore children's voice. Grounded in the sociology of pedagogic voice literature and building upon research on children's participatory rights, the paper explores children's experiences of being heard and actively participating in decision-making processes in diverse primary school settings in Ireland. It analyses children's voice by looking at their capacity to influence their own learning, contrasting their experiences and perspectives, to those of their teachers. Findings illustrate the interplay between children's and teachers' narratives regarding children's voice and their pedagogical encounters to explore the impact on teaching and learning processes, highlighting structural challenges to the realisation of children's voice in primary classrooms in Ireland.
