Interesting TEFL Course

I took the ITTT 120 hour TEFL course about a month ago and I found it most interesting. I have previously taught one on one but never in a classroom setting. This course is most useful in teaching you practically and theoretically how to teach an ESL class. I found that some units required more time to learn and understand than the time given in the course. I feel I should take this course once again before I would master its content even though I passed the course with grade A.

I took a master package TEFL course. The first certificate I got was 120 hour TEFL certificate during which I had maximum support from a tutor who provided me detailed feedback during the last phase of my course. I refreshed my knowledge of English grammar (since I have BA in English and I learnt most of those units before) but also learnt some new interesting and very useful things for the classroom teaching which I can also apply to my online English teaching. I am very satisfied and currently I’m taking Business course. After it, I’ll be taking TEFL course for teaching young learners. I recommend taking TEFL course to anyone!

Good experience

I taught and I’m teaching English as a second language now . After taking my TESOL with you , I feel more professional, my colleagues and friends asked me how creative and talented I’ve become recently in teaching, lesson plans making , timings, activities, I laughed and told them that I took an online TESOL,, and the program was so fascinating. My boss just told me a few weeks ago that I’ve become more and more efficient and he wished I could become a full time teacher at his school, unfortunately I can’t cause I follow a master degree at university at the moment . I have less time. I just recommended the ITTT program to two of my friends .
I’m glad for my training from ITTT International.
Thank you

I was definitely nervous to start my online training, as I am not the best virtual student. I emailed prior to purchasing the Master TEFL Course, to assure myself I’d checked all my skeptical boxes.

With all due reassurances in place, I began immediately.

I was impressed with the timing of the delivery of my log in details, course materials as well as the structure of the units. While discussing how to build a lesson plan, they are essentially taking you through one on a personal experience-basis. I found it very rewarding.

My uncertainty now comes from the initial butterflies of finishing a course and embarking on the experience. I was successfully satisfied with the learning aspect of ITTT, now I’m hopeful for the guidance and job-placement aspect they offer.

All and all, successfully certified and pleased to be starting a new journey!
