I just finished my first 120-hour course with ITTT. I've been an English and Reading teacher in the US for 30 years, and I learned an enormous amount on how to present and teach English to students not familiar with the language. The course materials and videos were great.
I took an online course and look forward to taking my next two courses, one that covers teaching businessmen and another that addresses teaching children.
I plan on combining knowledge of teaching in the classroom with online.
