The primary education sector includes state-funded primary schools, special schools and private primary schools. The state-funded schools include religious schools, non-denominational schools, multi-denominational schools and Gaelscoileanna (Irish-medium schools). For historical reasons, most primary schools are state-aided parish schools, although this pattern is changing. The state pays the bulk of the building and running costs of state-funded primary schools, but a local contribution is made towards their running costs. Teachers’ salaries are paid by the Department of Education and Skills, and the schools are inspected by the Department’s Inspectorate.
