Increased migration over the last two decades has resulted in greater diversity within Irish society. There is much debate around multiculturalism, diversity and integration, and how this is best achieved. As microcosms of society, schools have also experienced substantial growth in diversity. Over 90 per cent of second-level schools in Ireland record migrant students on their roll, with between 2 and 9 per cent of the school populations being migrant students. Moreover, research indicates that not only do teachers often struggle with increased diversity in the classroom but racism and inclusion are also not adequately addressed through the curriculum. Although Ireland sometimes prides itself on being a friendly and welcoming nation, racism is noted as a persistent issue. This article explores the topic of racism with teenagers in an Irish school, using the social work Dialogue Approach. This co-created study examines how students and teachers conceptualise racism and its impact. It is argued that exploring attitudes and encouraging dialogue among young people about the impact of racism and exclusion is fundamental to social work values.
