hope I'm not getting the wrong end of the stick here, but if your friend is considering going to work abroad, his/her Company should be able to sort out a school for their children.
Friends recently spent some years in Greece and their children were placed in the International School in Athens, this was a true International school and not the sort of thing monkey is talking about i.e. Turkish school with English lessons, which would presumably be unsuitable.
It seemed similar to a small private school over here and the Education they received was v.good.
