I am a qualified registered English/ESL high-school teacher. I have a Bachelor Degree and a Dip.Ed. I have worked as an ESL teacher in Sydney, but now that I am trying to go back to teaching English after having a child, I am told that I need another qualification - TESOL/Celta. It seems really unnecessary and expensive, besides the fact that I ALREADY KNOW HOW TO TEACH, ENJOY IT AND WANT TO GET BACK IN THERE!
