Not being paid for standardisation would be a big issue for me.
Some papers I mark on have standardisation with everyone is a room together paid by the hour, some via teleconference paid by a half day/day rate regardless of how long it takes and some online with chief examiner review paid by the script.
This is a vital part of the marking process and should definitely be paid for.
I don't get training as such so I don't know how that would normally be paid for, I remember a meeting once when the syllabus was changed significantly which was sort of training and was paid by the hour.
I've also been marking for nearly 10 years but my boards don't give me a grade, I work on the basis that if they keep asking me to mark I must be hitting the required standard.
I do worry about the future as the marking teams are well established but obviously getting older and on at least one of the papers new markers don't seem to last more than one sitting, edexecel have a very high threshold for being allowed to mark and I don't think they always give new examiners a chance to get to grips with the papers.
When I started I was given a lot of support and I'm not sure that chief axaminers are allowed the time to do that now, it's sink or swim which isn't good for the long term future as the experienced examiners start to retire.
