NESTs VS NNESTs

Well, I think that not only Native English Speaking Teachers can teach ESL, because I know that there are many good Non-Native English Speaking Teachers around the world that are well prepared for teaching ESL. I think that if someone knows a lot about grammar structures and has a good pronunciation, accuracy, fluency and many other skills they can perfectly teach ESL.

I think that the advantages that a Native English Speaking Teacher has is that he or she can make use of his English language experience. I think that a NEST has all the English vocabulary.

I think that Non-Native English Speaking Teachers can use their mother tongue when they are teaching English as a Second Language. Well, I think it´s better to manage more than a language, because it helps to a better teaching.
