The Irish religious landscape is changing. Census data reveal that the percentage of those who identify as Catholic is in steady decline, while the proportion of those with no religion continues to rise. Christian religious practice in Ireland is also decreasing, especially among young people. Catholic schools, once the dominant provider of second level education, are now in a minority. This changing landscape has influenced Religious Education in second level schools. It is now an optional subject, and the historic tradition of denominational, confessional Religious Education has given way to an approach designed to be inclusive of students of all faith and none. Yet the surrounding discourse is unsupported by the perspectives of Religious Education teachers. This study attempts to address this knowledge gap by investigating their views and experiences, particularly with regard to inclusion. Results indicate that teachers are concerned about ‘religious students’. Whereas new to the Irish context, this reflects international research which suggests that in a rapidly secularising society, those who continue to practice any faith, especially the once-majority faith, are vulnerable. Findings signpost evidence of this, with RE teachers most concerned about the bullying of Catholic students and least concerned about the bullying of atheists.
