As for British schools, I contacted them also, but got no reply. From what I understand they are looking for people with experience in the "British" system. I have tons of experience, but I do not have that experience.
You are right about that (they also want Int Bac experience). And there's only one worth even thinking about here (the British School of Warsaw) and that one is a significant step below the American School in terms of how good it is to work for.
HARRY - I would love to talk with one of those people working at the American school, just to get some info on some specifics.
Two of them left the year before last. The other two I have no contact details for but as the football season is starting soon, no doubt I'll be seeing them, will ask for contact details to pass on to you.
