TEFL、TESL、TESOLの違いが分かりません。
どれも英語教師になるための資格ですよね？
それ以外に、何か違いがあるのですか？

*TEFL - Teaching English as a Foreign Language
*TESL - Teaching English as a Second Language
*TESOL - Teachers of English to Speakers of Other Languages

I assume you know the defition for those. I just put them juts in case.

What I learned in a TESL class is that ESL students study English to SURVIVE IN an English spoken country, whereas EFL students study it to WORK WITH English (in a non-English spoken country). Therefore, although we, international students, are often defined as ”ESL stidents” here in Vancouver, we are actually EFL students unless we are immigrants.
Now you know the difference between TESL and TEFL.

I; however, don’t know what TESOL is. It looks like a little differet from other 2. I hope other people know abotu it and more and better information for TESL and TEFL as well.

This is all about your question I can answer.
Thank you.
