Firstly, I would like to clarify that I do not think poorly of teachers' intellect. I never wrote that, I never thought that and I don't think that. I was commenting on the course of study not the person taking the course of study and there is a difference. I feel that, by and large, teachers are let down by the system. I feel they're let down by a lot of people actually but that's getting away from the point at hand.
There are many tertiary education courses currently available and they vary widely. I should have stipulated which ones I meant (primary and BEds and in which streams, online v offline etc) as they are not uniform, are not consistent and do change depending on which state or territory you're studying in. Again, I should have been explicit about the requirements in Qld as states and territories do vary in their requirements and, again, they are not uniform. Yes, of course, a teaching degree has exams, assignments, essays, pracs etc like other degrees but not every degree is the same and I have come across quite a few that do not offer units in the areas I mentioned.
I also agree that a national registration body is necessary.
Hope that clears things up.
