Australians start going to school at the age of six. The following six years they are in primary school, which is run by the state or in a private school which is almost always run by a church. The schoolday is from am to pm. After primary school there is secondary school which takes another six years. School is mandatory until the age of fifteen. Most children leave school at this age. For students who live far outside a city, there is an institution called School on the Air. This school is conducted over the two-way radios.
Since dictionaries adopted the new spellings early on, there is no currently in-print, standard reference work available for traditional spellings. However, Theodor Ickler ( de ) , a Professor of German at the University of Erlangen , has produced a new dictionary that aims to meet the demands of simplification without the need to impose any new spellings. [ clarification needed ] It has not been reprinted since 2004. The commerce in used copies of the older Duden dictionaries has dwindled. As of the 2004 edition, the Duden dictionary includes the most recent changes proposed by the ministers of education.
