In Australia, academic ranks for a balanced position is usually broken down into 5 pay-scales (A Associate lecturer, B Lecturer, C Senior Lecturer, D Associate Professor, and E Professor), which somehow shows the level of seniority as well as the leadership responsibilities. There might be a few exceptions to this.
I noticed some Australian Level C academics translate their title to a North American Associate Professor title. This is really confusing to me as there is already a more senior Australian title with the same name. The assertion made here is that an Australian level D is similar to a full professorship in a North American country while an Australian level E is similar to a titled Professor in a North American country. I don't understand that as there are already many titled professors, senior professors and distinguished professors in Australia.
What is a correct comparison between the academic ranks in Australia and the North American countries? Is making a comparison even correct?
