4 Worst TEFL Courses 2026, written by Mia Williams – co-founder of Trusted TEFL Reviews.

December 8, 2025 Notice:

It has been brought to our attention that ITTT TEFL, My TEFL, and TTA The TEFL Academy have been offering their TEFL graduates free “bonus” courses (which are worthless) in return for writing a positive review on their Facebook pages and on the other review websites where they have hundreds of positive reviews.

This is the reason why ITTT TEFL, My TEFL, and TTA The TEFL Academy have such awful reviews on trustedteflreviews.com and amazing reviews on other platforms. This is a scam.

There are some excellent Online TEFL/TESOL certification course options out there, and there are some that you should avoid.

The best Online TEFL/TESOL certification courses come with excellent support and offer certificates that are Fully Accredited and internationally recognized.

The worst Online TEFL/TESOL certification courses lack sufficient student support and lack international recognition.

Here are the 4 worst TEFL courses in 2026, in all their upside down glory – starting at the 4th worst and continuing down to the worst of the worst:

4. ITTT International TEFL and TESOL Training

There are a few stand-out issues with the ITTT TEFL program:

1. It employs aggressive affiliate marketers that hype up the course on platforms such as Quora. The most prolific of these is Linda Dunsmore – Marketing Manager at (yep, you guessed right) ITTT. Linda spams Quora with helpful posts about how she was an ITTT graduate and how the course worked for her. What she doesn’t come clean about, though, is that she is on the ITTT management marketing team.
2. ITTT doesn’t just have one program website. Instead, it has more than 10 of them. They all look similar, but each contains slightly different claims and each looks different enough that the waters are muddied when it comes to pinpointing the true identity of the core company website.
3. ITTT is a company headquartered in Thailand, and they are accredited by some pretty dodgy accreditation companies. One of these is OTTSA, and another is The Teacher Training Council. Both are registered in Thailand, and both have been exposed as fake accreditation websites. The Teacher Training Council can’t even spell “Accreditation” correctly. They spell it, “AccrediDation”.

ITTT International TEFL and TESOL Training is Accredited but is not Fully Accredited.

3. MyTEFL

MyTEFL exploded into the Online TEFL training arena about 5 or 6 years ago.

It claims to have been around for a lot longer, but 5 or 6 years is a more realistic and honest assessment.

Students tend to like the course.

That’s where the positives end.

1. MyTEFL is propped up by a fake accreditation body ( Online TESOL and TEFL Standards Agency – OTTSA) and another one that they recently created: the International TEFL Accreditation Council – ITEFLAC. New! MyTEFL is now also “accredited” by the International Council for Online Educational Standards (ICOES). ICOES also accredits such bastions of international education including, but not limited to, ‘Permanent Jewelry Bestie’ and ‘spray tan class’.
2. Graduates regularly complain that they were ripped off by bait-and-switch scams on the job placements abroad that they accepted through MyTEFL and its parent company, Footprints Language Education Ltd. Teachers arrived to find that the accommodation and pay weren’t as promised, and some discovered that a percentage of their monthly salary was being deducted and paid back to MyTEFL/Footprints Language Education Ltd.
3. MyTEFL has tried to have fake reviews published on Trusted TEFL Reviews and reacted very poorly when we refused to publish these unverified “customer” reviews. Its response was to launch a campaign against us, claiming that this review website is biased toward certain TEFL programs. They even went so far as to claim that Trusted TEFL Reviews is owned by OISE University of Toronto TEFL and/or TEFL Online Pro. Yep, the true sign of a reputable company is to attack the reviews site that refused to publish its fake “customer” reviews.

MyTEFL is Accredited but is not Fully Accredited.

2. TTA The TEFL Academy

This company is a car crash waiting to happen, so go grab your popcorn and a comfy couch.

TTA The TEFL Academy claims to be “Fully Accredited” by a few organizations, with one of these being DEAC.

We sent out an inquiry to DEAC yesterday, and they responded that TTA The TEFL Academy is not accredited by them.

The helpful people at DEAC directed us to a page on their website, where the public can check whether a TEFL program is listed in their database.

Here is that link: https://www.deac.org/Student-Center/Directory-Of-Accredited-Institutions.aspx

1. TTA The TEFL Academy claims to be accredited by AQC, DEAC, QUALIFI, and even by Ofqual. It is accredited by no company. It is only regulated by Ofqual and QUALIFI, and it also appears that QUALIFI might have been created by the good folks at TTA The TEFL Academy.
2. TTA the TEFL Academy has tried to have its staff-written reviews published on Trusted TEFL Reviews. Last year, one of its full-time Brand Ambassador employees became infuriated with me because I wouldn’t publish her review that read like a TTA TEFL brochure. What was her response? She said that Trusted TEFL Reviews is biased and began writing rubbish about me and my reviews site online. Oh, and, of course, she claims that Trusted TEFL Reviews is owned by TEFL Online Pro because it is the top-rated program on this site currently. And all because we wouldn’t publish her review.
3. Despite having its headquarters in Dublin, Ireland, TTA The TEFL Academy certificates are not recognized for English teaching jobs in Ireland. In Malta neither. The one place where you are guaranteed to be able to use your TTA The TEFL Academy certificate is in the UK. Reviewers have complained about not being able to use their TTA The TEFL Academy certificates for some online teaching jobs and some overseas jobs.
4. TTA The TEFL Academy aggressively promotes itself through a network of affiliate marketers – people who may or may not have taken one of its courses. These marketing minions earn a 20% referral fee every time someone books a TTA The TEFL Academy course through their affiliate website. This is one of the reasons why we feel that TTA The TEFL Academy courses are overpriced.

TTA The TEFL Academy is Unaccredited. It is neither Accredited nor Fully Accredited.

The TEFL Academy, via its network of Brand Ambassadors, aggressively pushes the notion that it is fully accredited and aggressively pushes the notion that some of the reputable organizations that are competitors are Fully Accredited are, in fact, fake. I hear defamation lawsuit bells ringing!

1. ESLinsider

The popcorn and couch time might have already passed with this program because our research has shown that ESLinsider is not a full-time-functioning TEFL program anymore.

I spent a lazy Sunday searching through the many Reddit user names of the owner of ESLinsider TEFL (Ian Patrick Leahy) and I read how he returned from Japan to New Hampshire because his website wasn’t doing so well. In the two years since then, Ian has worked on ski and snowboarding slopes in New Hampshire and Montana.

It appears that he is now planning on working a summer season this year in Oregon.

I also read some of Ian’s Reddit questions – enquiring about traveling to either Chile or New Zealand for under-the-table paid work.

Why does ESLinsider come in at number 1 for the worst TEFL courses in 2026?

1. Ian Patrick Leahy began the ESLinsider TEFL program because he hated teaching English and wanted to earn a quick buck by running online TEFL courses, which he called TEKA courses. The problem was that he didn’t have enough experience or knowledge to even teach, never mind running a training program. This didn’t deter Ian and he soldiered on, creating linguistic minefield disasters as his objective grew.
2. He was clever in one respect. He created a blog for ESLinsider, where he tried to convey the impression that he was an ESL expert. He also “reviewed” his competitor’s TEFL programs (which he never even paid and took) and wrote critical feedback on them – all the while linking back to his blog and to his ESLinsider course. This meant that you could Google any well-known Online TEFL program and you would see ESLinsider’s take on it. The obvious reason for spending so much of his time doing this was that he hoped to convince people that his TEFL course was better and that they should pay him to take his course. His MO is to claim that such and such a course or person is a “scam”, “fake”, “fraud”, etc. He also went after reputable accreditation bodies – after all, his courses were unaccredited so he had to try and angle it that accreditation bodies are all fake.
3. Ian (ESLinsider) was the first TEFL program that we received a fake review and it was the first time that a TEFL program retaliated against us for not publishing its fake review. Ian Patrick Leahy from ESLinsider was the person who began the misinformation that Trusted TEFL Reviews is biased and owned by CIEE TEFL, OISE University of Toronto TEFL, and TEFL Online Pro. Of course, this is not true.
4. He is also alleged to have conned his paying customers out of their money. This is one example of a group of Ian Patrick Leahy’s ESLinsider TEFL students, who were left out of pocket by Ian:

ESLinsider is Unaccredited. It is neither Accredited nor Fully Accredited.

ITTT TEFL Accreditation

It was recently brought to our attention at Trusted TEFL Reviews that the ITTT TEFL Accreditation claims are questionable.

ITTT is an acronym for International TEFL and TESOL Training.

Firstly, we think it important that readers understand that ITTT TEFL runs multiple websites to sell the same bunch of its course offers.

These are:

https://www.teflcourse.net/

https://www.teflonline.net/

https://www.tefl-tesol.net/

https://www.tesolcourse.com/

https://www.tefl-certificate.net/

https://www.teflcorp.com/

There are probably more duplicate sites listed under other URLs.

This is an immediate red flag because it shows that this company is trying to muddy the waters with regard to its core business website identity.

Trusted TEFL Reviews took a screenshot of the footer of the accreditation page that lists ITTT’s apparent affiliations.

At first glance, it certainly looks impressive!

ITTT TEFL lists its Affiliations and Partners, and boy, there are many!

Here is that screenshot:

Now, let’s look at the claims and delve into the truth.

ITTT TEFL Partners

The “Partners” are just websites that ITTT TEFL pays to be listed on and pays advertising money to.

A couple of the websites are dubious forums, notorious for a lack of any oversight, and a few of the websites are TEFL review websites that earn their money from the affiliate marketing model that they operate. In other words, they earn advertising money from the TEFL companies that they promote.

This is an obvious conflict of interest scenario because it is in the interests of those TEFL review websites to hide negative reviews and let fly fake positive reviews – reviews that are often written by the TEFL school itself.

ITTT TEFL Accreditation (Affiliations)

The Paris College of International Education is an online program, which is similar in stature to the University of American Samoa – go sand crabs!

OTTSA has been written about in detail on Trusted TEFL Reviews and has been identified as being a less-than-reputable TEFL accreditation body, based in Thailand – which, btw, is where ITTT TEFL is based. Search for “OTTSA” in the Trusted TEFL Reviews search box and you will see what we mean by “less-than-reputable”.

iatefl is an organization that, for an annual fee, will allow any TEFL program or education company to display its logo on its school website.

BGS is God knows what.

The Bangkok School of Management is reputable, but in no form or way accredits ITTT TEFL.

The Teacher Training Council spells “Accreditation” with a “d” instead of a “t” – “Accredidation”.

What reputable accreditation body misspells “accreditation”?

And, what does it tell you about a company that chooses to affiliate itself with an accreditation body that can’t spell “accreditation” correctly?

It appears that the Teacher Training Council not only has issues with spelling “accreditation. They also clearly have an issue with dates.

The following are two screenshots from the Teacher Training Council accreditation website – taken on 24 March 2022 and one taken of an archived version of the same page on 19th January 2021:

Furthermore, it is my guess that both Costa Rica TEFL and Will-Excel likely never applied to the Teacher Training Council for accreditation.

It is also my guess that Costa Rica TEFL and Will-Excel’s school names were added to the “Accredited TEFL / TESOL Programs” page simply to make the page seem more believable because people would think that there is a review process to become accredited by the Teacher Training Council (which, clearly, there very likely isn’t).

Given the above information, we suggest treading with caution when pondering your ITTT TEFL/TESOL training options.

There are lots of dodgy TEFL accreditation bodies out there.

We always recommend referring to the TEFL Accreditation Guide when weighing up which TEFL/TESOL accreditation will work best for you:

https://trustedteflreviews.com/tefl-accreditation-guide/

Also,

Take a look at the TEFL Directory for guidance:

The top-rated schools in the directory are top-rated for a legitimate reason.

Stay safe out there!
