Do I require a university degree? I don't currently hold a degree.
Would my Glaswegian accent kill my dream of teaching English in China? I don't have a strong Glasgow accent however.
But I know that there is TEFL teachers in China without degrees, how did they do this?
I'm 20 and have no experience in English teaching. Am I too young?
I've been teaching part time in a provincial capital. I have an American colleague who, like you, is 20 & doesn't have a degree - or TEFL certification. He's earning USD1000+/m & spending only about 10% of his salary on accommodation. On the -ve side his legal situation probably isn't 100% above board (work permit obtained in a different city).
The foreign teacher who wrote a lot of the materials for the school, has a pretty strong Birmingham accent - I know because he appears in the adverts for the school.
So if you're prepared to work in a private school in a less popular location it should be possible - particularly if you're white*. But you might need to apply to quite a few places first.
* Not being racist, but from what I've heard - & seen - it does make a difference, unfortunately.
