Lancelot - was thinking the same thing, but worried in case I came across as a snob.
I believe graduate entry teaching pays about 23k per year. The only reasons I can think for a graduate to take the role is either
a) graduate is of low calibre
b) the candidate lives in Doncaster (i.e. lives rent-free with Mum+Dad and sees this as a way of saving for a deposit for a mortgage)
or c) graduate is desperate to get into aviation and see this as a way of gaining aviation credibility with a view to moving to a new role after 2 years.
