Hello!
i am from china. now i am working at a tour company. i have been studying english last 5 years . now i have a good command of english. i got 6 on IELTS exam last year. now i am thinking to be a teacher in the future. i search lots of course online. many said that thier's are the best. but i am confused about to take which one?
is CELTA ok for Non-native speakers? or do we have to take TEFL first before get CELTA?
which TEFL is the best on the base of classroom in china?
many thanks!

CELTA is fine for non-native speakers, but you will need at least an IELTS 6.5 or 7.0 to get on a course. As well as working on your language, you could take a course to prepare for the Cambridge TKT (Teaching Knowledge Test)
