Aistear: The Early Childhood Curriculum Framework, was launched in Ireland in 2009. The framework is applicable in all settings where children in the 0-6-year range are present; this includes all early years settings and the first two years of primary schools, referred to as “infant classes” in the Irish context. This article shares the findings of a local research project which sought to explore the implementation of “Aistear”, by Early Years Educators (EYEs) and Primary School Teachers (PSTs) in pre-schools and infant classes. This research, based on a qualitative case-study design, was primarily focused on those educators working with children who are between three and six years of age and was based in the North East region of Ireland. The study examined the implementation of Aistear and how educators adapted their existing curriculum and daily routine. Thirteen educators participated, including six EYEs and seven PSTs. The collected data was thematically analysed with the emerging story captured through five key themes: Emergent Curriculum, Social Development, Communication, Holistic Development, and Implementation of Aistear. Overall, the benefits for children’s social interactions, language development and cognitive development through play in a child-led environment were discussed by participants. However, training, ratios and resources were a concern and a requirement for EYEs and PSTs. The recommendations from this study indicates that further research into the implementation of Aistear on a national scale would offer greater insight into the adaptation of the curriculum framework within pre-schools and infant classes in primary schools.
