How long does a TEFL course take? Most people finish the standard 120-hour course in two to eight weeks, depending on how many hours a week they put in, while a 180-hour Level 5 diploma typically takes six to ten weeks. Both are self-paced online, so the real answer is: as long as you need, up to a generous six-month access window.
Which is a relief, because “how long is this actually going to take” is usually the question people are too embarrassed to ask until they’ve already paid for the course and are staring at the login screen wondering if they’ve made a horrible mistake. You haven’t. Let’s break down the actual timelines.
How long does a TEFL course take: the master comparison table
The honest answer to how long does a TEFL course take depends entirely on which course you pick and how many hours a week you can realistically commit. Here’s the breakdown by course length and study pace.
| Course | Fast-track pace | Typical part-time pace | Maximum access window | Accepted where |
|---|---|---|---|---|
| 120-hour TEFL | 2-4 weeks | 4-8 weeks | 6 months | Global minimum standard: most of Asia, Latin America, online teaching platforms |
| 180-hour Level 5 TEFL Diploma | 4-6 weeks | 6-10 weeks | 6 months | Competitive markets and higher-paying roles: Middle East, some European school contracts |
| 240-hour TEFL | 5-7 weeks | 8-12 weeks | 6 months | Same markets as 120-hour, plus specialist modules (business English, young learners) |
| 300/310-hour Advanced Level 5 Diploma | 6-9 weeks | 8-14 weeks | 6 months | Highest-tier roles, international school preference, strongest CV signal |
Source and methodology: timelines reflect typical completion patterns reported by students on self-paced online TEFL courses as of 2026, based on an average study commitment of 3-6 hours per week for part-time pace and 15-20 hours per week for fast-track pace. Individual pace will vary.
Why the same course takes some people two weeks and others two months
Course length on paper is a fixed number of hours. Course length in practice is about your actual free time, and those are two very different things. A 120-hour course is, unsurprisingly, 120 hours of material. Do fifteen hours a week (roughly two evenings plus a chunk of Saturday) and you’re done in two months. Clear a free week of annual leave and dedicate it entirely to the course, and plenty of people finish in seven to ten days flat.
What actually eats up the time
It’s rarely the reading that slows people down. It’s the assessments at the end of each module, since most courses require you to pass each one before moving to the next, and the practical teaching components on the higher-hour diplomas. Build in extra time for those rather than assuming you’ll fly through module quizzes the way you skim a Netflix recap.
“I am currently doing the Teaching Business module and I am thoroughly enjoying the training course… As the module is available online, I can work on the course in my free time, so I greatly appreciate the flexibility built into the courses.” – Sean R, Trustpilot review
120-hour vs 180-hour vs 300-hour: which length should you actually pick
If you’re only going to teach online or in a country with a low bar to entry, 120 hours covers you and gets you working faster. If you want Middle East contracts, higher pay, or you just like having the stronger qualification on paper before you’ve even applied anywhere, the 180-hour Level 5 Diploma is worth the extra few weeks. I knew someone who did the 120-hour course purely to “test the water,” loved teaching within a month of starting, and went straight back to add the Level 5 diploma on top once she’d already landed a job, which meant paying for and studying two courses instead of one from the start. If there’s a lesson in that, it’s: decide on your target market before you enrol, not after.
Studying with a related qualification already in hand
Having a degree, especially in English, education or linguistics, doesn’t shorten the course itself, but it does tend to speed up how quickly you move through the content, since a lot of the grammar and language-analysis sections will already be familiar. It won’t turn an eight-week course into a two-week one by itself, but paired with a genuinely free week, it helps.
Studying while working full time: realistic weekly plans
| Weekly hours available | Best suited course | Realistic finish time | Study pattern that tends to work |
|---|---|---|---|
| 2-4 hours/week | 120-hour TEFL | 3-4 months | One weekday evening + a Sunday afternoon |
| 5-8 hours/week | 120 or 180-hour | 6-8 weeks | Two evenings + most of one weekend day |
| 15-20 hours/week | Any length, including 300-hour | 2-6 weeks | A dedicated week off, or daily 2-3 hour blocks |
Choosing your course length before you enrol
Before you commit, it helps to actually look at where you want to teach and check the minimum hours employers there expect. Our TEFL courses page breaks down course options in more detail, and if budget is part of your decision, our cost of becoming a TEFL teacher guide lays out what each course length actually costs once you add extras. If you’re switching from a completely different career, our TEFL for career changers guide covers how the timeline fits around a working life. And once you’re certified, our teach English abroad page is a good next stop for internship and placement options.

How Long Does a TEFL Course Take? Course Lengths Compared
One of our graduates in Ho Chi Minh City told us she nearly talked herself out of the 180-hour diploma because “ten extra weeks” sounded intimidating on the course page, then finished it in six because she batched her assessments on Sunday mornings instead of trying to do a little bit every single day. How long does a TEFL course take often comes down more to your weekly rhythm than the headline number of hours.
Frequently Asked Questions
Most people complete the standard 120-hour TEFL course in two to eight weeks, and the 180-hour Level 5 Diploma in six to ten weeks, depending on how many hours a week they study. Courses are self-paced online with up to six months of access, so you can go faster or slower as needed.
It is possible on the 120-hour course if you can dedicate fifteen to twenty hours across that week, but most people studying alongside work or college take several weeks rather than one.
Yes, in some markets. The 120-hour course meets the global minimum most employers ask for, but the 180-hour Level 5 Diploma or higher can open up better-paid roles and is sometimes required in more competitive regions such as parts of the Middle East.
Most online TEFL courses give you a generous access window, often around six months, so there is no need to rush. If you are close to a deadline, course providers will usually let you request an extension.
A 120-hour course is fully accredited and accepted by most employers worldwide. It is not “worse,” it simply covers less ground than a 180-hour or 300-hour diploma, which include extra modules like teaching young learners or exam preparation.
