After completing my degree I qualified as a high school Geography teacher in the UK. After one year of teaching I moved to South Korea, due to the poor job market. I intend to move to Vietnam in around a year. At that stage, I will have had two and a half years experience teaching ESL. I have been teaching middle school and have taught very low level students, up to high level TOEFL and an advanced class including such activities as debate and mock trials.
I intend to travel for a month or so before moving to Vietnam to begin my job search. My question is, do I need a CELTA qualification to be in with a chance of finding employment? If it is not necessary I would rather not for financial reasons and also the fact that it would not really impact my qualification at home.
I have found varying opinions on message boards but a number of the posts are older and could possibly be out of date.
Is it too much of a risk to go without first taking the CELTA? Would I only be able to find less reputable jobs with my qualification and experience?
Thank you
