What our graduates say

"The course was extensive and was a fantastic way to recap meta linguistic rules and learn the best techniques for teaching. I learned a number of useful techniques and was able to adjust my teaching style accordingly."

Tshego Nyoka

40 Hour TEFL, August, 2021

“I am currently working for one of the most progressive English institutions, and this is all thanks to English for Asia. They empowered me with both the confidence and knowledge to conduct English lessons. Therefore, should anyone wish to further your knowledge, I strongly recommend English for Asia”. 

Thomas Komane, Online Teacher JHB, EF Teach Online

40 Hour TEFL, February, 2022

"As a person who had little teaching experience, the TEFL course helped guide me in developing my skills and improving my teaching method. It also taught me practical teaching techniques that will be beneficial for both me and my students. With a TEFL certificate that is internationally recognized, it provides lots of opportunities."
