I am interested in guaging peoples' opinion on the consistency of ABRSM examiners. ABRSM claims to be very professional in its examination system and ensures that grades awarded are consistent across examiners. I found this was not the case. At one series of exams I was awarded 97/150 and the next series (same exam, new pieces and six months later) I was awarded 117/150. I know that the standard was not that different between the two performances and yet the marks differed by 20 points. Have others had similar experiences?
