There is definitely no need to pay extra for the videos and tutors. Everything is written for a ninth-grade reading comprehension and all the concepts are kept quite shallow. No critical thinking is required to pass with a 90% or higher in all the units.
The vast majority of the theories and pedagogy are only discussed in a sentence or two, so you don't get a very rounded perspective on teaching ESL. There is only one method that is used in any detail, so that you feel you have no choice but to use that method in your own teaching because it's the only one you really understand.
If you already have a strong command of English, just be aware that the grammar and the poorly-aged content can make the units a bit of struggle. The materials clearly have not been updated in a decade or two.
Some of the units will make you do your own research because they don't cover it, but still require you to know it. This includes having to read a downright offensive piece about judging a culture based on its masculinity level (femininity is not a part of this piece as they take the view that femininity is simply the far low scale of masculinity).
Response from ITTT TEFL
Hi Amelia. Thank you for taking the time to submit a review. We’re not sure what caused your change of heart with regard to ITTT since you emailed us on 8th June 2022 after we gave you a deadline extension on your course free of charge: “Thank you so much! I greatly appreciate it and this really just goes to show what amazing and remarkable company you are. I am so happy that I chose to get my ESL certification through ITTT and I recommend your company to all my friends who are seeking the same training.”
We’re sorry to hear that you didn’t find the videos useful or that you didn’t take advantage of the tutor support that was available to you throughout the course. The feedback that we usually get for both these areas is usually very positive, but we understand that the needs of all course participants will inevitably differ. We acknowledge the comments you submitted in your unit reflections and some changes will be made.
In your YL course unit reflections you mentioned that you were frustrated that you needed to do additional research as part of the course requirements. Every task sheet (which you were advised to complete before each unit test) stated that further research from other sources may be required.
