Reviews by Graduates

I have recently completed the 120-hour Advanced 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 several years, I discovered so many useful techniques so I recommend the OnTESOL course even for those who already have experience teaching English. My tutor, Aaron, was wonderful. He is a great guide who walked with me through the whole course, 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!

Yana Demtsun

I have enjoyed using my OnTESOL course for the past 7 years in life, in Cambodia and in Taiwan.

The lesson plan assignments and assistance I received from the kind tutors helped me to become more creative in the classroom. I would recommend this online TESOL course to anyone that would like to know more about Teaching English as a Second Language and developing their lesson planning skills.

Thank you OnTESOL for your help all these years after completing my course. I feel you have done a lot to assist me in my career.

Patrick Meir

Excellent online course. I was a little skeptical at first that the online course would not compare favourably with the classroom course but I was pleasantly surprised. I was able to apply 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.
