While inclusion has generally been accepted as orthodoxy, a knowledge-practice gap remains which indicates a need to focus on inclusive pedagogy. This paper explores how teachers in the Republic of Ireland primary school were supported to develop inclusive pedagogy to meet the needs of learners with special educational needs (SEN). It is underpinned by a conceptual framework which combines an inclusive pedagogical approach and key principles of effective professional development (PD) arising from the literature, which informed the development of a professional learning community (PLC) for inclusive practice in a primary school. The impact of the PD on teachers' professional practice was explored using an evidence-based evaluation framework. Analysis of interview and observation data evidenced that engagement with inclusive pedagogy in a PLC, underpinned by critical dialogue and public sharing of work, positively impacted teacher attitudes, beliefs, efficacy and inclusive practice. This research offers a model of support for enacting inclusive pedagogy.
