This system has been in place now for about twenty three years - to begin with, it was very biased to the left, but over time with governments from both left and right in power, the bias is less - and with care, you can keep away from most of what is there.
In the two years before these two years (Grades 9 and 10), while we have curriculum guidelines from the state, as a private school, we don't have to follow them. All we really use it for is broad topic outlines - so in Grade 9, we study European and Australian history from 1750-1918 (and the First World War in some detail), and in Grade 10, mid twentieth century history. We also do units on Ancient History (Sumer, Egypt, Crete, Greece, Rome) in Grade 9 and Medieval history (primarily English, but with some Europe and the Crusades) in Grade 10, but that's outside the curriculum guidelines. It means our students do quite a bit more work than the curriculum requires - but certainly not more than they can handle with effort and diligence.
We also intergrate to some extent with other subjects - all boys have to take at least one year of Latin, and those who continue it beyond that point have it interacting with their Roman history studies, for example. We'd probably do more of that if the History teachers (including me) remembered more of our own Latin - but I only did it as a schoolboy myself and it's been a long time since I was a schoolboy now.
Thank you for such a thorough response. I’ve heard somewhere in the distant past that Australia tends to run about 40 years behind the USA in terms of social norms. Whoever said that may have been totally uninformed for all I know, but I do tend to think of Australia as less advanced in a good way when it comes to leftist thought and practice.
I trust you are not unaware that public schools in the USA in certain places are obsessed with psychology at early ages as opposed to the more straightforward matters that should attend to an educated population. What I mean is, we have areas where it is impossible to fire teachers who think it is more important to know how to put a condom on a cucumber than it is to know who George Washington is, and what he stands for.
