I'm considering pursuing a career in TEFL (I don't have any TEFL qualifications yet). I'm 36, British, and I have an MA. I would like to volunteer to teach English for a few months, ideally in Crete, to see how I get on. Is that realistic? Where should I look? My perfect scenario would be teaching kids under 10 (I've never stood up in front of a class to teach, and I think teens would be way too intimidating). I have no idea where to begin.
