Reviews by Graduates
I have recently completed the 120-hour TESOL Certificate Course. I think this course is incredible and I would highly recommend it to anyone who wants to get into teaching English as a foreign or second language. Even though I’ve been teaching for sevel years, I have discovered so many useful techniques so I suggest that course even for those who think they are good at teaching English. My tutor, Aaron, is wonderful. He is a great guide who walked with me through the whole course and helped whenever I had problems and always got back to me in a timely manner. I want to thank OnTESOL for providing an unforgettable learning experience !
I have enjoyed using my OnTESOL course for the past 7 years in life, in Cambodia and in Taiwan.
The assistance I received from the kind instructors that helped me to be creative and develop the way to teach. I would recommend this course to anyone that would like to know more about Teaching English as a Second Language and developing the skill of making lesson plans.
Thank you OnTESOL for your help all these years after completing my course. I feel you have done a lot to assist me in growing and succeed in teaching English.
Excellent online course. I was a little sceptical at first that the online course would not compare favourably with the classroom course but I was pleasantly surprised. I was able to use much of my new knowledge immediately. I took the 120-hour course plus the course for business English. I applied for ESL work in the business sector immediately after completing my OnTESOL course and received a favourable answer to all my requests, finally settling with the YMCA in Montreal. I never thought the course would be so helpful especially when it comes to lesson planning.
