Diversity is a hallmark of the sector, diversity of faith, philosophy, size, students and approach. The sector is a kaleidoscope of school choice. There are schools that educate children from Prep to Year 12 and those that only cater for primary or secondary students. There are coeducational schools, single-sex schools, distance education schools and boarding schools. The majority of the state’s more than 220 independent schools have a religious affiliation, while the remainder are guided by their individual school missions and educational philosophies.
