CIEE TEFL review, submitted by Ned.

I did my TEFL/TESOL certification with CIEE TEFL in September 2025. It’s a very comprehensive course, and consists of a logical series of gradient steps (modules, tests, lesson plans, and written tasks). I found the information was consistently straightforward and understandable. The course has obviously been designed by experienced teachers who know their subject in and out, as it tells you exactly what you need to know and how to apply it in real-life teaching situations. I also appreciated the clear, concise content of the course, which made the previously intimidating subject of grammar seem quite simple to understand and teach to others. I now feel confident to successfully begin teaching English to speakers of other languages and nations. I’ll begin teaching online and progress to in-person classes once I’ve a few months’ experience under my belt.

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 Sarah.

I completed the 150-hour course online with 20 practicum training hours (also online) in August. As a native speaker, I still found some sections difficult; notably the grammar sections. I’m convinced this is because no one taught me grammar when I was a kid at school. I can’t understand why they don’t teach grammar in schools. For this reason, I think non-native speakers will have an easier time taking a TEFL certification course. CIEE TEFL is one of the 5 best-recommended companies to TEFL train with and I could tell it was an excellent program because of the way everything was so well organized and because of how attentive the tutors were. I did pass the course (distinction) and I’ve been teaching English online ever since. Five stars!

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, submitted by Ursula.

My experience studying the TEFL qualification online with CIEE has been enjoyable. The level of education and the support I have received through this online program has been nothing short of wonderful. It’s great to see that this company cares and doesn’t just treat its student teachers like an inconvenience or a source of extracting as much money as possible from them. I would like to take time out to thank Tutor Annette for doing a great job in providing the support I couldn’t have managed without. Both Annette and other members of the CIEE admin made themselves completely available and gave the impression of genuinely caring about my course success. Also, CIEE has been working with me on my TEFL job options since completing the course. I would highly recommend CIEE to anyone who wants to earn a TEFL certificate while managing a busy lifestyle.

CIEE TEFL review, submitted by Jose.

If you want to work in the EFL industry, this course is a good choice. It only took me 4 weeks to complete it in total. Found teaching work online easy with the certification. My only critical point is they don’t offer many further training courses. When they do, I’ll be signing up for one. This is a very organized company and their online tutors know what they are discussing. You can’t go wrong!

I recently completed the CIEE TEFL course and had a very positive experience. The content was clear, well-structured, and easy to follow, even for someone new to teaching. I especially appreciated the support from the tutors. They were responsive, encouraging, and provided thoughtful feedback on assignments.

The course gave me a strong foundation in teaching methods, lesson planning, and classroom management. It also included a practicum, which was a great way to apply what I learned in a real setting.

While it’s a bit more expensive than some other courses, I feel the quality and support made it worth it. I’d definitely recommend CIEE TEFL to anyone looking for a reliable and professional certification.

150-Hour TEFL Certification CIEE TEFL review (https://www.ciee.org/) submitted by Christine.

150-Hour TEFL Certification.

The CIEE TEFL program was the only one offering the 150-hour course with 20 hours of real-world teaching practice. The price was a little steep, but when I compared all the fees with the in-class ones it still came out as being significantly more affordable.

I taught my 20 hours to students online. This was something that I preferred doing, as opposed to teaching in person. The 100% online format suited me just fine. Teaching the training classes online also meant that I gained that experience of the online teaching English side of things. I have been teaching online since and this course prepared me very well for that.

A little about the course now.

It is designed nicely and obviously has been created with the student teacher in mind. There aren’t lots of fillers, so all of the information conveyed is absolutely relevant for the given module you are on at the time. I had the support of an online tutor, who was great throughout. I couldn’t have imagined taking the course without this tutor’s help. Some of the parts are difficult (especially the grammar modules) so these were times when having someone on the other end to guide me was a great reassurance.

I consider CIEE TEFL to be an excellent company for online teacher training.

I highly recommend them and I also highly recommend teaching English online.

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 (https://www.ciee.org/) submitted by Drew.

This was a really great TEFL option for me. I didn’t have the money to travel overseas for an in-class TEFL course, and I didn’t really have the time for it either. Plus, the costs of taking the TEFL in class are prohibitively expensive. I searched online for in-class courses and they want $2,000 just for the course. Then, there are the travel and accommodation expenses, and I know that I always spend more money in a country where I am new in. So, when I found out that this option existed online I went ahead with my online search and CIEE TEFL was the school that kept showing at the top of Google search. It isn’t an online/in-class course per se, because you teach the in-class segment online, but it’s the closest thing you’ll get to a fully in-class course and the price of the course was significantly lower than if I had taken one in a bricks and mortar facility overseas. As far as I can tell, the certificate issued through the CIEE program is practically identical to the in-class certificate examples I’ve seen on Google Images. When I interview for jobs now, I write that I have an in-class TEFL certificate and this hasn’t been at all questioned. I recommended this course to friends.

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

I recently completed the English as a Second Language (ESOL) teaching program online with CIEE and it was one of the best things I have ever done for myself. The convenience of completing the study section of the course at your own pace made the whole thing possible for a busy person like me. The “in-person” teaching classes were arranged via Zoom. These were a lot less flexible but I was prepared for this as I understood that I would have to take into account the available schedules of my students. It was not easy. Between work, family, friends, and downtime it was tough. But the ability to start and stop when you want/can as opposed to having to travel in-person for the training was a no-brainer to choose CIEE. Best of all, it is affordable. In total, I paid $1,100 for the entire training program. If you are planning on changing career paths and switching to teaching ESOL but don’t have the time, I would recommend CIEE. Just be prepared though that like any online program you are responsible for yourself, only you can get it done for you. I had support from my family and this helped me through the days when I was finding it difficult to juggle work and study. I haven’t used the certification yet but I do plan on using it in the not-so-distant future. I enjoyed my CIEE TESOL experience and I know the certification will come in useful for later adventures.

I am very glad I took the CIEE Certification course and I highly recommend it. I didn’t have any prior experience as a teacher before I took the course, but my amazing instructor guided me through the learning process and was always there for me. She helped me understand the different aspects of teaching and the importance of my students’ cultural and personal differences. I liked that the course is structured in a way that allows the students to finish their assignments on their own time. I was able to balance my full-time job and the online classes.

CIEE TEFL review, submitted by Stanley.

I just finished the Tefl course from Ciee Tefl. I’m probably quite a lot older (in my mid-50s) than the average age of a Tefl student I guess. Despite this, I managed to make my way through the course without coming up against any significant challenges. There was a tutor available online who gave great support anyway, so if I weren’t sure about something I would email them and ask for their advice or recommendations. I completed the course with a high final grade. If I can do it then anyone can. I wouldn’t say the course is that difficult. There were moments – mainly to do with grammar topics – when I felt out of my depth, but it was never so complicated that I felt I couldn’t work out how to understand the information. It also helped that I could apply the new knowledge when I created the lesson plans because this showed me how I was improving in real-world metrics.

I am 100% satisfied with my CIEE course purchase and feel lucky I found this online program.
