Thank you for your feedback during the course. This course was a great recap/refresh on my actual English. As an older college graduate, I truly see sometimes you can forget a lot of things you actually learned in college. Many thanks for making me think about what I am teaching to other students who are not native English speakers.

  • I stumbled upon TEFL Source while I was researching the EPIK teaching program in South Korea. I didn't realize there were so many course types and companies out there. TEFL Source made it easy to browse through the different programs, although many aspects of the programs are comparable, and find a suitable course that included teaching practice. I'd tell you I'd use them again but I doubt I'll need another TEFL certification. All in all, a happy customer. Jenny Bae
  • So far so good! Enrolled in a 120hr course last week and already completed the first 2 modules. Kudos to the TEFL Source staff for walking me through the different options and taking the time to explain what I needed, and what I didn't for that matter, in order to teach over in Korea.Rhea Csergei
  • Overall I'm quite satisfied with my experience with TEFL Source. They're not the end providers of the courses but they do offer lots of useful information, more than other sites I was checking, and their staff was quick to respond to my onslaught of questions! Also saved some money on the course I wanted which was good for my wallet :) Anton G.
