This study explores principals’ attitudes towards the suitability of language immersion education (LIE) enrolment for children with dyslexia in Ireland. It also aims to examine the challenges faced by those in LIE settings working to include children with special educational needs (SEN), specifically dyslexia, in their schools. Participants include primary school principals working in Irish LIE settings across Ireland. The study follows a mixed methods approach including a focus group interview and a self-completion online questionnaire. Results indicate that principals believe that LIE enrolment is suitable for children with dyslexia and that these children can benefit from being placed in such a learning environment. However, the Irish immersion system faces considerable challenges in its aims to support children with dyslexia, namely the lack of an appropriate assessment system, the lack of sufficient research and training and negative attitudes held towards the Irish language.
