Alot of the time a 'propper' pre school is often run by the dept of ed. and are attached to primary schools. They are open from 9-3 like a school and have a very structured day like Sarah mentioned. They employ early childhood teachers and are 'pre' school, meaning that the set up and structure is made to get kids ready for school. You might find that alot of places that are called preschools are not actual 'propper' pre schools, but are set up how the owner/director would like the program to be. Although long day care centres and other styles of childcare centres must document all of the developmental areas you mentioned above, they are more free in their programs, often still meeting the same outcomes for children going to school, but not actually teaching them like pre school would. Does that make sense?? They also employ teachers, but not all staff members are trained, some are untrained and some are tafe trained, some uni trained.
