There are approximately 3,300 primary schools in Ireland. The vast majority (92%) are under the patronage of the Catholic Church. Schools run by religious organisations, but receiving public money and recognition, cannot discriminate against pupils based upon religion or lack thereof. A sanctioned system of preference does exist, where students of a particular religion may be accepted before those who do not share the ethos of the school, in a case where a school's quota has already been reached.
