Criteria other than that wich can be directly measuered and quantified is subject to the individual biases of the panelists. It wouldn't be that fair.
You are assuming there is a panel, a committee of some sorts that hand out the grades. I think this kind of "justice" thinking gets more abundant then. If the rank is seen as something between the student and the teacher who gives the rank, it will always be biassed - if you do not like your teacher's way of beign biassed, find a new teacher.
