In the past few years, Trusted TEFL Reviews has witnessed a significant increase in complaints from consumers who have purchased a 120-hour TEFL/TESOL course for less than US$100.

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 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.
