Northern Ireland is regarded as the most traditionally Christian country within the UK. Publicly funded Schools in Northern Ireland are either State or Catholic maintained schools. State schools can be classed as: Controlled (by the Education Authority), Voluntary Grammar, Integrated and Special Schools. Irish-Medium Schools are operated by both the State and the Catholic Church. Despite the common notion of 'Protestant' and 'Catholic' Schools among many citizens, all State schools accept all religions without bias, with the exception of Integrated schools which require a set ratio of 40:40:20 Protestant, Catholic and Other(Mixed or non-Christian Religious). An identification with the "Protestant" or "Roman Catholic" community is sought on equal opportunities-monitoring forms regardless of actual personal religious beliefs; as the primary purpose is to monitor cultural discrimination by employers. Atheists should select which community they come from, however participation is not compulsory. Religious Education is compulsory for all children up to the age of 16, with the four major Church denominational bodies (The Catholic Church, The Presbyterian Church in Ireland, The Church of Ireland and the Methodist Church) agreeing on the content of the syllabus, focussing on Christianity and Secular Ethics. World Religions have to be introduced between the ages of 11 and 14. An act of collective Christian worship is mandatory in all Northern Irish schools, usually consisting of a short Bible reading, lesson or dramatisation and a prayer during morning assembly.
