Although the systems of public schools differ among Australia, South Africa and the USA, all three countries recognize that religion plays a significant role in determining values. All three countries have written constitutions but only South Africa and the USA have a Bill of Rights that protects persons' exercise of religious beliefs. In Australia, the place of religion in education has largely been shaped by state legislatures, administrative regulations and interpretations of the national constitution. In the USA, the long tradition of religious values being represented in public education has been severely restricted over the past 60 years, resulting in artificial judicial lines being drawn between private religious expression and government expression. However, even private expression can be prohibited if it interferes with the educational mission of a school. South Africa had a long tradition of Christian religious practices in government schools under apartheid. However, the post-apartheid 1996 Constitution and 1996 South African Schools Act still give these schools considerable latitude in investing religious values into the educational process. In Australia, values, religion and education have always been a preoccupation of those providing education, although the blurring of public and private education in Australia has resulted in a different direction for the role of religion than in the USA.
