EPIK Review: Teaching English in South Korea with EPIK

Teaching English Online as Full-Time Student

“Reflecting on my overall experience, I am so grateful for the OnTESOL course that laid the foundation for my success. Its curriculum and detailed assignments not only honed my skills but also equipped me with the necessary tools to dive head-first into teaching. From using the lesson plans from my course assignments with my current students to receiving invaluable feedback and tips from my tutor, OnTESOL was a crucial step in my ESL teaching career.

EPIK Review: Teaching English in South Korea with EPIK

From Lebanon to Canada

“Moving to Canada, I had to keep my teaching skills up to date and OnTESOL was a great opportunity to polish that. The 120-hour TESOL course refreshed the methodology I used and taught me new concepts about lesson planning that I haven’t seen before. The assignments are devised to teach future ESL teachers the skills they need to plan lessons and stand in front of a classroom.

“I highly recommended taking this course to anyone venturing into pursuing TESOL as a career in Canada or internationally. OnTESOL will prepare you as a skilled English teacher who knows how to plan lessons outside of the ESL textbook, and it will also empower you to do so with any level of students.”

EPIK Review: Teaching English in South Korea with EPIK

Teaching With EPIK in South Korea

“The OnTESOL course gave me the background knowledge of teaching English to kids and understanding how they learn a new language. It also provided me with the tools to create a lesson plan from start to finish and how to carry out that lesson in reality.”


K-12 English Teacher in South Korea

Teaching English in Hubei, China

OnTESOL’s courses did a great deal to support my teaching career in China.

The program provided me with a deep understanding of teaching, especially in the areas of lesson planning, teaching approaches, and methods. It also has a strong grammar focus.

The course helped me to use the right terminology in the classroom. The 20-hour TEYL course was in-depth as well and it showed me how to manage kids in a classroom setting.”

120-hour Advanced TESOL Certificate

Teaching English in the UAE

 “TESOL training can improve your classroom practice, helping you make your curriculum more accessible to a broader range of learners. To this end, the 250-hour TESOL Diploma can be transformative, as it provides a clear, well-structured framework for developing lessons that support holistic language learning, and ELLs in the UAE need teachers sensitive to the importance of building lessons around sound ESL approaches”.

TESOL certification review Toronto

Teaching English in Toronto, Canada

“I took the TESOL course with OnTESOL  because I needed a credential that is recognized in Canada. I already did the whole teaching abroad thing and now I was looking to settle down in my home country. I wish I had known about OnTESOL before going abroad! Taking the TESOL course with OnTESOL allowed me to study on my own terms. I loved the support that I received from my tutor during the online course and the Practicum“.

120-hour Advanced TESOL Certificate

Teaching English in Madrid, Spain

“OnTESOL was my first and only choice and they haven’t disappointed me. The course work is laid out logically and tackles the most important elements. While I went into the course largely to formalize my experience, I came away much stronger than before I did the 250 hour diploma. I’m the sort of person that likes to learn at my own pace, but I must say OnTESOL certainly provided me with perspectives and grounding that really pointed me in the right direction“.

Robert Siliniez 

250-hour TESOL Diploma

Teaching English in Thailand 

“The 120-hour Advanced TESOL and the 20-hour TEYL specialist certificate courses offered by OnTESOL prepared me to teach kindergarten at my private academy. I’m thankful for the lesson planning practice and insight on different teaching styles. While my academy provides all of the lesson plans, I can comprehend how the instructors wrote the lesson.

I decided to go with OnTESOL because of the flexibility to work online and at my own pace. My tutor was amazing, responsive, and provided constructive feedback to help me improve. The course was challenging, but I’m thankful for the support.”

More Reviews from our TESOL Graduates:

I took the online course and completed the practicum afterwards. I took this course after teaching in Korea for over 6 years. I expected to gain little, thinking that after being in the classroom for over six years, they probably couldn’t tell me too many new things. Boy, was I wrong! I can’t believe the difference between my classes now and in the past. I am enjoying teaching even more and my students are responding to my new techniques. Not to mention that they are talking so much more. We’re all being so productive. The work was hard, but the lessons, assignments, exams, and in-class teaching were unbelievably helpful. I can honestly say that when I studied a lesson at night, I could take what I learned and apply it with great results the next day. Not to mention the great support and feedback you get from your tutor. I will always be thankful for the advice, patience, and influence she gave me. Thank you again! I highly recommend this course to anyone with a love for teaching English. Cheers!

I really enjoyed it and I learned a lot. My tutor was very helpful in working with my concepts and simply teaching me how to improve on my assignments. All my questions were always answered. This has been a fantastic experience.



Thank you so much for giving me such a wonderful experience. Teachers were nice and patient. I treasure my learning experience at OnTESOL.


Hong Kong

I have really enjoyed the whole ONTESOL experience. I spent a long time researching different online courses and the ONTESOL course was the most comprehensive. I had no prior teaching experience and felt that this was a good way to get an insight into what TESL is all about without having to commit myself to perhaps a year or more of formal teacher training. I feel that the course has a balanced approach to different teaching techniques and the Grammar and Phonology modules are well thought out and detailed.

My tutor, Carl, was incredibly dedicated and responded quickly to my many questions, even when I interrupted his weekends. His answers were always concise and instructive as well encouraging and I really feel that I have learnt a lot, both from the course and from Carl´s comments and guidance. For anyone new to teaching who can’t afford to have a sudden career change by going back to college full-time, I think this course will be entirely suitable, especially as it provides the practicum option which will provide the full “teaching experience”. I can’t wait to put it all into practice.

I found this online course to be incredibly helpful. I liked the fact that it was so hands on and that it gave me so much practice with designing different kinds of lesson plans. I also liked the course’s emphasis on grammar and phonology, which are areas of teaching that many TEFL teachers don’t know much about but are extremely important nonetheless.

Justin DeFerbrache

United States

I really enjoyed taking this course. My instructor did an excellent job with advice and suggestions. He clearly knows his stuff. The course material has exactly what I was looking for: good explanations, lots of examples and quality information. Maybe it’s just a 100hr class, but I feel like I’ve got a good foundation to dive into ESL teaching. Thanks for everything!

Charles McDougal

United States

I was very pleased with the whole experience. The grammar and phonology modules were great in-depth reviews. The methodology module was an excellent step-by-step guide of how to plan a lesson. I have a better understanding of how students learn and feel much better prepared now to teach a class. My tutor, Aaron Marques, gave very insightful comments from his personal teaching experience. He was a great tutor, always responded quickly and like I said, gave very insightful comments and was always very encouraging. He really made the program! Ontesol was a great course for me as it gave me the flexibility to work from home and in my own hours.

Monika Robertson

United States

Before beginning the TESOL program I assumed it would be a no-brainer, upon beginning I realized I would have to put a bit of effort into this in order to receive my TESOL certification. Upon finishing the program my self-esteem has been boosted like I never imagined. My tutor Danielle was great, a true asset to ONTESOL. I highly recommend this program! A+

Tammy Schmidt


The tutor was so helpful and gave very useful comments on my work. The assignments were excellent and very practical because they gave me good practice in creating my own lesson plans. The TESOL course has definitely given me more confidence in planning lessons and conducting English classes.
