What is the hierarchical ranking system for academics in your country?

I am in Australia and here we have a ranked system with Professor being right at the top (Level E), Associate Professors (Level D), Senior Lecturer (Level C), Lecturer (Level B) and then Assistant or Associate Lecturers (Level A) (No PhD. May be post-doctoral students). There are also research only positions.

You don’t automatically move up through the rankings, you have to be promoted to move out of your tier. So an academic might stay at the same level for years and never meet the criteria to move to the next tier. They may be employed on a continuing basis (often serving a three-five year probationary period) or on a casual/fixed term basis.

Those who work for universities around the world (or know the system), how does it work in your country?
