Ireland’s education system at primary level is renowned for its lack of diversity, with most schools falling under the patronage of the Catholic Church. This homogeneity of school type is problematic from a number of perspectives, not least the changed demographics in terms of religious affiliation in Ireland. There is a desire for change by all; however, the pace of change is slow. Whilst the National Council for Curriculum and Assessment (NCCA) determines the curriculum for all subject areas in primary schools, this body has no remit over the subject of religious education (RE). The responsibility for the provision of RE has rested with the patrons of schools since the inception of the national school system. This review focuses on the provision of early years’ Catholic RE in schools and pre-schools in the Republic of Ireland. In recent years, the importance afforded to the subject of RE and its status in schools has been eroded. The impact on early childhood religious education of this diminution is outlined. The review also addresses the training and support of teachers to work in the Catholic school sector and concurs with other writers in the field that current programmes of preparation require reform.
