The participation of multilingual children in minority language immersion programmes is under-researched internationally. The Republic of Ireland (RoI) has become a linguistically and culturally diverse society. In the RoI, parents have the opportunity to educate their child in English-medium or Irish-medium (IM) schools. However, the cohort of multilingual children attending IM schools is very small. This study investigated the reasons why parents who spoke a home language other than Irish or English chose to enrol their children in IM primary education. It also investigated parents’ perceptions of the benefits of this form of education. Semi-structured interviews were undertaken with 15 parents from a variety of language backgrounds. It was found that parents were motivated to enrol their child in IM primary schools to provide them with the opportunity to learn a variety of languages at an early age. Benefits associated with learning multiple languages and immersion in Irish culture and heritage were seen as the main advantages of IM education. A minority of parents chose an IM school when there was no space for their child in an English-medium school. Parents reported that they did not experience significant challenges in IM immersion. Recommendations arise to support the participation of multilingual families in immersion education.
