jce:There is no restriction or \"law\" as such, it's down to the teacher if he/she has the \"guts\" to take on a higher grade student. I think majority take on the Dip (performance) because it is \"easier\" to prepare, in the sense that one only prepares the pieces to be PERFORMED. The marking will be judged on the way pieces are performed. Whereas the teaching Dip requires one to have a portfolio, showing a wide range of students. In the exam, one is also required to show how one would teach a particular piece to a student, in other words, the teaching part is emphasised. The performance of the pieces prepared is less of an issue.I see, I see. Thanks a lot for your enlightenment.
