you are correct, and for top flight international schools in bkk, for example, they may well require more-- not just a degree in any old thing, but a degree specific to the subject taught and previous teaching experience. I have several friends working at ISB and a other at Pattana. some, again, think to the many years ago, when just speaking English was enough-well that day has passed. Yes, maybe, and often illegally without work permit, and for very low salary, one might find an English teacher job in a distant rural school.
