I'm contemplating taking on an external examiner role for a post-grad qualification. I've done PhD external examining before, but not for a whole qualification. Obviously it would be a good thing for my CV but it's not an essential for my particular situation, so I'm trying to work out whether the fee they are offering (£500 p.a.) would counterbalance the need for nights away from the kids and/or general disruption of working somewhere away from home a few more days a year (I presume they pay expenses on top of that, but don't know that for sure). And part of that is - is this the going rate? I don't have any further info at this stage about how much work it would be, but my impression is that there's very little relationship between the amount of work and the fee anyway for all these kinds of academic extras.
So, any external examiners out there, especially for post-grad quals (Masters level), how much do you earn and how does it relate to the amount of work it is?
