I have an interview for an international school I am really keen to work for. The problem is, it's the only school I've applied to in the true hope of getting a job and am keen to work there. Is it the norm to contact references before interview/offering post? I'm worried because this is the only job I've applied for so haven't told my current employer. If this falls through, I'm more than happy to stay put for a year or so. I don't want to rock the boat. Any advice?
