One of my colleagues sent me the link to this March 5 Sydney Morning Herald article tonight: Christian schools angry over ban on teaching creationism
The SMH article reports on response to:
a decision by the South Australian Non-Government Schools Registration Board to effectively ban the teaching of creationism.
Under policies published in December, the board said it required ”teaching of science as an empirical discipline, focusing on inquiry, hypothesis, investigation, experimentation, observation and evidential analysis”.
The board said it ”does not accept as satisfactory a science curriculum in a non-government school which is based on, espouses or reflects the literal interpretation of a religious text in its treatment of either creationism or intelligent design”.
Comment from Creation Ministries: Australian Christian schools in creationism row
My colleague suggests that if Lutheran Education, a significant education provider in South Australia, threatened to withdraw from schooing over this issue that some notice may be taken by the authorities.
Firstly, I believe that whatever they say, the authorities in various education departments would be delighted if every non-state education provider did withdraw.
Secondly, I also believe that Lutheran Education probably already had a policy pretty much like this already in place, before it became official. Some within the system will have some relief that they can now point to government policy when parents come and complain about the absence of interaction with design from their curicula. Lutheran Schools are church schools, not Christian ones.
It is smaller, usually non-denominational, Christian schools that are firmly in the sights of this move.
In any case, the move should win the support of some evangelicals in Sydney.

What does registration mean? Is it compulsory, or does it just mean you receive government money? He who pays the piper, calls the tune.
All non-government schools need to have their curriculums approved by State Education departments, whether you accept money or not.
Even home schoolers who register need to demonstrate their curriculums meet those standards.
These are the sort of situations that would be leading some parents to not register their children with the education department.
It doesn’t have much to do with money, as I wrote in the post, I believe most education bureaucrats would prefer for there to be no private education at all on ideological grounds.
It doesn’t matter if you bear all costs in educating your children, what they really want is control of what they’re learning.
