 Hello, this is Lin from China. I took a standard 120-hour TEFL and TESL course from the ITTT, and now I got the certificate. I felt it was a rewarding experience for me. Besides the major grammatical units explained in the course, like parts of speech, present past future tenses, conditional, passive voice, pronunciation, etc., it also covers English teaching theories, methods, and techniques. It tells the teacher how to prepare lessons, choose appropriate equipment, and magic glasses. The ITTT course also provides plenty of books and online resources for teachers to refer to. However, if those resources could be categorized more clearly, it would be better and easier to choose from. Anyway, in a word, it was a smart move to choose the ITTT course for obtaining TEFL and TESL certificate that was accepted globally. And it would be especially useful for those teachers who started English teaching at early stage. Thank you.
