Our verdict

Our verdict9.0/10

For a regulated TEFL qualification at an online-course price, The TEFL Institute's 180-hour Level 5 Diploma is hard to beat: $365 (October 30, 2026) for a Highfield qualification on the UK's Ofqual register, assessor-marked written work and 26 hours of live Zoom classes.

Choose it if you want a Level 5 to show employers in Europe, the Middle East or competitive Asian markets and can keep to written deadlines. If all you need is a basic 120-hour certificate for an online platform, Premier TEFL's $175 course is enough. The catch is the assessment rules: a third attempt at any assignment costs $35, a missed resubmission deadline can fail the course, and access ends for good at 18 months.

Best for: aspiring English teachers who want an Ofqual-regulated Level 5 TEFL qualification online, with assessor-marked written work, for a few hundred dollars.

Somewhere in your job search, a better ad turned up. A language school in Madrid, a corporate English contract in Dubai, or a well-paid online academy, and instead of “120-hour TEFL” it asked for a “Level 5 TEFL” or a “regulated qualification”. That one line splits the TEFL market in two. Most cheap courses sell a provider’s own certificate. A Level 5 is a qualification listed on the UK government’s register, with assignments marked by assessors.

The TEFL Institute, an Irish company founded in 2017, sells one of the cheapest routes to that second kind. Its 180-Hour Level 5 TEFL Diploma was $365 on October 30, 2026, and it leads to the Highfield Level 5 Diploma in TEFL, qualification number 610/1571/4 on the Ofqual register. You can check that number yourself.

How we reviewed it: on October 30, 2026, we read the US course page, the full terms and conditions, and the Ofqual register entry, and compared the course with the other TEFL options on our site. We first checked it on October 7. We haven’t taken the course.

Pros & cons

✓What we like
  • Highfield Level 5 Diploma on the Ofqual register (610/1571/4), at $365
  • Written answers marked by assessors and returned within 3 working days
  • 26 hours of free live Zoom classes and two 60-hour Level 5 Awards included
  • 3-day free trial of real course modules before you pay
  • Two interest-free payments if you can't pay at once
!Watch out for
  • No teaching practice in the online diploma; the hybrid version adds 10 hours of live practical training
  • A third submission of any assessment costs $35, and assessment fees are non-refundable
  • Missing a resubmission deadline without arranging an extension fails the course
  • Access ends for good at 18 months, extensions included, and your progress is deleted
  • On the two-payment plan, you can't pass Module 3 until the balance is paid
  • 14-day refund carries a $35 fee and ends once you reach Module 3

Price, and what comes with it

$365, shown against an “original price” of $655 with a countdown that we’d ignore: the price was the same on October 7. You can pay in full or in two interest-free payments, the second 30 days later. On the two-payment plan, the terms say you can’t pass Module 3 until the balance is paid.

Included: six months of study time, two 60-hour Level 5 Awards (online and one-to-one teaching, and teaching business English), 26 hours of free live Zoom classes, job coaching seminars, the jobs board and an enrolment letter. That’s a lot for the money. The provider’s own non-regulated 120-hour course cost almost the same when we first checked, which makes the Level 5 the obvious pick between the two.

There’s a three-day free trial with access to sample modules. Use it.

What studying it is like

The diploma has ten units, each with its own credit value on the register. Grammar is the biggest at 30 guided hours, then vocabulary, learners’ needs and teaching methods, reading and listening, writing and speaking, pronunciation, materials, lesson planning and online classroom management, teaching adults and teaching young learners.

A typical week might be three evenings: a unit’s text and videos on Monday, a podcast on the commute, then the module test on Thursday. Multiple-choice questions are marked automatically. The open-ended written answers go to an assessor after every three modules, and the terms commit to returning marked work within three working days. That written feedback is the real difference from a cheap certificate: someone reads your lesson plan and tells you what doesn’t work.

The catch: the assessment rules

This is the part most buyers skim and later regret. Each assessment allows two free submissions. A third costs $35, and assessment fees aren’t refundable. Fail all three and the course is recorded as a fail.

Deadlines are strict. When an assessor asks you to resubmit, you get five working days as standard. Miss a deadline without arranging an extension first and, under the terms, the course is failed. You get one free 10-day extension; after that, extensions cost $35.

Access has a hard ceiling. Six months are included, and you can buy extensions, but total access stops at 18 months. After that, it’s suspended permanently and your progress is lost.

None of this is unreasonable for a regulated qualification. But if your life is unpredictable, plan for it: start when you have three clear months, and email before a deadline, never after.

The refund window is short too: 14 days, minus a $35 fee, and only until you reach Module 3 (terms as read on October 7).

No classroom

Like most online Level 5 courses, this one has no observed teaching practice. If you want some, the provider sells a 190-hour hybrid version that adds 10 hours of live virtual practical training. Otherwise, the 26 hours of Zoom classes are the closest you’ll get to watching teaching happen.

Level 5 against Level 5

The obvious question is why pay $365 when i-to-i’s 180-hour Level 5 was on sale at $189 the same day. Both are regulated Level 5 qualifications, so an employer who asks for “Level 5” will accept either. The difference is in what surrounds it: here you get two extra 60-hour awards, 26 hours of live classes and the written feedback process described above. If those extras matter to you, $176 is a fair premium. If you just want the qualification on paper, the cheaper one does the job. Whichever you pick, check the register number on the provider’s page against the Ofqual register before paying.

Who it suits

People who want the qualification that better-paying schools ask for, without paying for a classroom course or travelling. Self-disciplined learners who can write coherent answers and meet a five-day resubmission deadline. Non-native speakers with C1-level English, which is the stated requirement.

Who should pick something else

If you’re only teaching on an online platform that asks for 120 hours, Premier TEFL at $175 covers it. If you want a classroom, an in-person course like Essential TEFL in Bangkok gives you real students.

FAQ

Is The TEFL Institute Level 5 worth it?

For most people who want more than a basic certificate, yes. At $365 (October 30, 2026) it's an Ofqual-regulated Highfield qualification with assessor-marked work, which is what employers asking for 'Level 5' mean. If you only need a 120-hour certificate for online teaching, a cheaper non-regulated course will do.

How long does The TEFL Institute Level 5 take?

It's 180 guided learning hours, self-paced, with six months of access included. At 8 to 10 hours a week, most of that window is enough. Extensions can be bought, but total access stops at 18 months and your progress is lost after that.

What happens if I fail an assessment at The TEFL Institute?

You get two free submissions for each assessment, with feedback within three working days. A third submission costs $35. If you fail all three, the course is recorded as a fail, so read the assessor's comments carefully before resubmitting.
