I've never done it, and neither have any of my students. A polite "good morning/afternoon" is all that's required I think. And "Thank you, goodbye" when the exam is over. That's my experience..others may encourage hand-shaking.
This is what I have always done in graded exams (I think)- but as I stated, it has been some years. Teenaged then I may have shook their hand.

Perhaps if you have a couple of 50 quid notes concealed in your palm which you carefully leave in his after shaking hands....


I'm already paying them once!!

Yes - both before and after. It's probably my age and background, but it seems the most polite and natural thing to do. The first upon introduction and the second on 'completing the business'. It also helps me settle before playing. I don't think my two recent examiners have seen it as anything other than politeness. They were in both cases standing face to face. Had they been sat down writing, no eye contact, etc., then maybe there would have been no handshake.
This is what is confusing me. Having now had the benefit of interviews and auditions of all kinds, It would seem weird to meet a respected musician and not shake their hand!

I don't think it would make a difference to the marks...
I agree. In fact it would be ludicrous if it did.
I don't think it will make any difference to the mark. I would be upset if it did. It is just a matter of ol' fashioned (exam) ettiquette. I can't remember if i did when I was younger, but I probably did. Now I am

and the thought had crossed my mind. Asking seemed the best way to find out views and answers from people who are going through, or have gone through, the same process. Thank you for all the answers so far.
