Virtually all state-funded primary schools – almost 97 percent – are under church control. Irish law allows schools under church control to consider religion the main factor in admissions. Oversubscribed schools often choose to admit Catholics over non-Catholics, a situation that has created difficulty for non-Catholic families. The United Nations Committee on the Rights of the Child in Geneva asked James Reilly, the Minister for Children at that time, to explain the continuation of preferential access to state-funded schools on the basis of religion. He said that the laws probably needed to change, but noted it may take a referendum because the Irish constitution gives protections to religious institutions. The issue is most problematic in the Dublin area. A petition initiated by a Dublin attorney, Paddy Monahan, has received almost 20,000 signatures in favour of overturning the preference given to Catholic children. A recently formed advocacy group, Education Equality, is planning a legal challenge.
