By shifting professional courses to postgraduate level, the University of Melbourne claims to put students from all backgrounds on an even footing (HES, July 6). The nationwide ranking system (ATAR) is an objective and scaled measure, and takes into account various factors such as the difficulty of subjects, teachers' marking leniency, and so on. If the highly subjective undergraduate grade point average is used instead, it just becomes a dog's breakfast.
It is well known that the effort and ability required to obtain a certain grade varies enormously between universities and within different subjects and faculties of a university, and there is no means of standardising it.
The real reason for the Melbourne model is to increase income by keeping students at university longer and being able to charge full fees.
