Education in Australia is free and primarily the responsibility of the individual states. In each state administration, the training and recruiting of teachers are centralized under an education department. Education is compulsory between the ages of 6 and 15 in all the states exclude Tasmania, where the upper age limit is 16. About 73 % of students attend state schools. In addition to the state school system there are private schools, which are usually denominational and charge tuition fees. The majority of the private schools are Catholic. Some private schools, which in some states are called public schools as in Britain, accept day students and boarders.
