This 120 TEFL course was very efficient to those working persons giving a specific timeframe to complete. The resources for additional information was very useful especially for teachers to use in the future. The course was effective and easy to follow and prompt responses were given from the tutors if needed. It gave a broad overview of content that is essential for English learning that I did not know existed. The information was clear and concise going straight to the point to help the reader understand. Many examples were given to help in future if any issues is to occur and how you can relate to them to the students.

TEFL Online is great

ITTT 170-hour TEFL course was a challenge for me. I was surprised by how dense and informative the course is, therefore useful when starting your teaching career. In the beginning, I was worried if I am up to this challenge, but after some time I understood that I am getting a needed foundation to become a professional. While refreshing grammar was an inevitable element that was expected, an upgrade with teaching methods, tips and tricks created an ensemble that is at the highest level. It was motivating and given through a pleasant user interface. From one unit to another I felt more confident that I am building knowledge that I will use and return to from time to time to enforce my career and overcome any possible obstacles. Great work, ITTT!

  • Steep learning curve
  • Easy to use user interface
  • A wonderful support
  • Give us more online games and activities

The best course ever

I’m currently teaching English in the countryside of São Paulo in Brazil.
I’ve just taken the one hundred seventh hour TEFL course. I can absolutely recommend ITTT for anybody who already teach and who wants to improve your skills as a teacher. This is the course you are going to need if you would like to teach abroad or online.
Now I have more knowledge for planning my lessons and new activities. I enjoyed everything about the course, but my favorite one was ESA methodology.
As a result, my students are enjoying learning English. So, GO FOR IT!

What was the most surprising thing you saw or did?
The best thing about this course is the ESA methodology. Now I have more knowledge for planning my lessons and new activities.

Harder than you think; better than you think!

I chose ITTT because I have a US Bachelor's and Master's degree, but many of the overseas teaching courses wanted a TEFL certification. It wasn't the cheapest program, and I'm happy I paid the extra for it. To me, though some of the terms were different, I don't really differentiate between British English and American English. To me, English is English. So while I had to spend a little extra time absorbing some of the different terms - the explanations and concepts were the same. The links they provided were excellent. I didn't need any support because I'm a good learner and simply reviewed again what I'd missed on previous tests. I also downloaded and printed each chapter to make a workbook that I can take with me. It's a good course.

What was your funniest moment?
When I realized the my lesson planning was all messed up and that I had never actually used more than a straight arrow plan - sorta sad, and funny all at once.

My experience

I would like to let you know that what motivated me to do the Diploma course was originally to up´date my qualifications and to receive an international recognition for my teaching experience and qualification, which is national. This goal has been achieved.I would like to outstand the role of my tutor, who was always ready and willing to give me advice.
Although I graduated in 1982, I have always been involved in teaching English as a Foreign Language to all-age-groups or classes and this course has shown me that, all the courses i have done since 1982, and congresses or lectures I have attended or taken part in, have kept me up-to-date in different educational areas.
I would recommend adding or designing a course suitable for TEFL online or blend´learning. I have been doing many courses since I finished my Diploma, and all of them were related to TICs. Forunately our own platform was ready for March, when all the COVID 19 local lockout started, but I have found that I am not an expert at that, and this online or blended learning method will be the future in education. Thank you for your interest in our experience

What would you improve about this program?
I would add or design material for e and blend teaching EFL as this is the coming trend and it would be very important to incorporate practical knowlege regarding this aspect. I am sure that most of the teachers from all over the world would benefir from it.

TEFL better than TESOL

I've enjoyed TEFL more because I was provided with all the theory that was necessary to complete the course. With TESOL, I had to search for all the information by myself. I do understand that self-studying is required in any case but I could've done the same thing without paying $400. Still, I have to admit that the information I was encouraged to research was very interesting and I enjoyed it, and the format of tests was very nice and even engaging. I also appreciate the short summative tasks in TEFL that helped me to remember how to write essays, so I was prepared for a bigger essay at the end of the TESOL course

What would you improve about this program?
Providing sources where I can find the information that I need to complete the tests would be very helpful. I would still spend time reading it through and learning it but I wouldn't have to waste hours on trying to find a good source that will definitely give me an answer to the question in the test.

Good course it opens up for new opportunities

I liked the freedom to study at my own pace and where I wanted through the online courses. The support was good and the platform for studying as well. I enjoyed the videos. The online course is not too expensive. Doing this course opens up new opportunities around the world. It would be nice if the course managers would pair up students somehow to create a social network among the students even if it is just with another student only. It would be nice if the school had contact with employers and could also cooperate with employers and future and current TESOL teachers.

What would you improve about this program?
Some job adds don´t accept TESOL teachers with just an online Diploma. If there is a way you can solve this. This issue exists, you could be more clear about it and how to solve it from the teacher's end as well.
