CIEE TEFL review, submitted by Aster.

Overall the course is excellent. Very easy to navigate and they assist you if you need help. I needed a lot of help due to not being versed in any form previously in TEFL or TESOL. I literally went in blind. I think you do need to prepare yourself for a course like this because it is for the TEFL certification and there are sections of the course which are very difficult. Or at least there are sections that require you to stop relying on muscle memory alone. It was also the first time I’ve sat down and studied since college and that was a sharp shock when I began. My advice is prepare yourself that some of the course will be fun and easy and some of it will be difficult and laborious. I’m sure all TEFL courses must be like this because I don’t see any way you could teach the subject without it being the way it is. I’m applying for jobs currently in Thailand, and the support is still there for me. I have interviews lined up next week. Wish me luck!

Online TEFL/TESOL course scams exist- be wary of any programs not listed on Trusted TEFL Reviews. A program not listed on Trusted TEFL Reviews might be a scam.

If an Online TEFL/TESOL certification course program doesn’t have a company Facebook page, or if it does and has the Reviews tab disabled, be likewise wary.

The Online TEFL/TESOL industry (yes, it is an industry) is highly competitive. Online TEFL/TESOL schools writing misleading trash about their competition online is a common occurrence. Verified customer reviews are your friend. Anything else is probably just mudslinging by a business competitor.

Online and abroad employers expect you to have either a 120-hour TEFL/TESOL certificate or a 140-hour TEFL/TESOL certificate if it includes 20 hours of teaching practice.

You do not need more.

Some TEFL/TESOL programs offer 168-hour TEFL courses and even courses with 170+ hours. These course lengths are unnecessary and will not increase your chances of employment.

If you already have TEFL teaching experience, a 60-hour refresher course will be enough.

If you don’t have TEFL teaching experience, a 120-hour or 140-hour course will be enough.

CIEE TEFL review, submitted by Marc.

This online course was easy to navigate, and I could log in and study at times that suited me and my schedule. The course presentation and content were excellent, and there were fun tests to ensure you understood the content before moving forward. There is an additional fee for the issue of the TEFL certificate, which I thought was very reasonably priced when considering that this is a fully accredited program. Immediately after my certificate was issued, I started applying for jobs online.

It has taken a while to get my hours up to nearing a full-time teaching schedule. I’m nearly there now and before long I’ll be having to turn down offers from new students because I don’t want to teach more than 30 hours a week. Teaching online has so many advantages, but it is also exhausting teaching some students. This might not be specific to teaching online but might be the same as teaching in-person classes. I do plan to transition to in-person teaching this fall, and the certificate from CIEE will help me reach my next goal. I would say the course is well worth it.

CIEE TEFL review (https://www.ciee.org/) submitted by Rosie.

For the most part, I enjoyed online learning with this program. I have recommended CIEE TEFL to others. My tutors were engaging and interactive. They gave valuable feedback on lesson preparation and on how to manage students in a classroom and were willing to go out of their way to help increase understanding. The part I had the most difficult time with was the grammar section. It took me repeated attempts to fully understand the nuanced differences between the various time tenses and I’m still finding it difficult to explain these to students. The students I teach don’t have Perfect tense structures in their language, so it’s tough going trying to explain to them when and why they should use the Present Perfect instead of the Past Simple. This isn’t being critical of the program. They just don’t teach us this in school, so it’s made much more difficult when we are required to teach our mother tongue All of this taken into account, for the most part, I enjoyed the course.

CIEE TEFL review, submitted by Christian.

I found the CIEE 150-Hour TEFL course (online) to be good value for money and instrumental in enabling me to teach English to online learners. Communication with the school has been very good; both during the course and since completing it and earning my TEFL certificate. CIEE run an internal messaging board, where you can chat with their other teachers, and this has been so helpful when seeking up-to-date information on which countries have been opening their borders to foreign teachers. For the time being though I’m pretty content teaching online. I’ve been working for Palfish for a while now. They pay a fairly decent hourly rate, and I’ve had my pay bumped up twice now as they get to see that I’m a dependable teacher to have on their books. What’s really the benefit of teaching online though is the complete flexibility that comes with this line of work; no travel time and I’m now able to (by mutual agreement) move my students around so I don’t have gaping time slots between classes. Teaching through a computer does take a bit of getting used to, but after a week or so I settled into it and began realizing what does and what doesn’t work. I think I’ve been lucky because (so far) I haven’t experienced any of the classroom management issues which I’ve seen some other teachers sometimes experience teaching distance learning (young) students. After this, I’ll probably head over the ocean to teach somewhere in S E Asia. If the world ever gets back to pre-Covid normality again that is. But for the time being, I’m very content with the current arrangement.
