Thank goodness you're back TD
Re Grad Dips for primary teaching - I had a friend who looked into this and generally the 1 year grad dip may need to be 'topped up' with an extra subject or two in the area you are seen as lacking in. For example, someone with a science type degree would need to do a bit of extra study in English. This friend was in NSW. He had to submit his various qualifications and work experience to be assessed. As it turned out, with an arts degree and later post grad stuff in computer science etc. his education was considered broad enough and rounded out enough that he didn't need anything more than the 1 year Grad Dip.
That being said, when they made this possible for people I very much doubt they had in mind a Primary school where ALL the teachers were grad Dips. The norm would be for the vast majority to be truly teacher trained, and the 1 or 2 grad dips could get help from their colleques.
If they are ALL grad dips it seems a bit like the blind leading the blind.
You mentioned before about discipline at the school, but never given any details. Are you able to tell us more?
cheers
