ABSTRACT Since the publication of the Education for People with Special Educational Needs Act in 2004, inclusion in Ireland has become a priority for the educational system. Despite the promotion of physical education (PE) as a key setting for facilitating inclusion in schools, research has shown that the children with special educational needs and disabilities are still excluded from PE. Research evidence shows that teachers’ attitudes and self-efficacy and the broader school context within which teachers work are among the most important factors facilitating inclusion in PE. Therefore, the aim of this study was to explore teachers’ attitudes towards inclusion, self-efficacy in delivering inclusive pedagogies, and perceptions about whether inclusion was supported within the schools. A cross-sectional design was used, and a questionnaire was sent to Irish PE teachers. Results of this study showed that teachers’ attitudes were positively correlated to the number of different types of disabilities in PE class. It was found that secondary school teachers had higher self-efficacy levels than their primary school colleagues. Findings from this study revealed that teachers who had frequent personal contact with SEND people showed more positive perceptions about the extent to which inclusion was supported in the school within which they worked.
