With the norm referenced system there is no pass mark, because each student is allocated a grade determined by where their attained mark falls on the Normal Distribution Curve. We were taught that A-levels exams were marked using norm referencing. One of the interesting characteristics of norm referencing is the relationship between the number of students attaining a particular grade, and the number of students sitting the exam. If there is a year-on-year increase in the number of students sitting a particular A-level examination, there will be a year-on-year increase in the number of students attaining A-level grade A in that examination. Like the horse and the cart one will always follow the other.
Of course one of the other interesting characteristics of this system is that year-on-year variations in examination standards have no effect on the resulting grades. Good isn't it?
