Signing up for a TEFL course is one of the first big steps toward a life of teaching, exploring, and connecting across cultures. But as soon as you start looking into certification, one question comes up again and again: how long does it actually take to finish?
Whether you’re aiming to teach English online from your laptop or jet off to a classroom in Thailand, knowing what kind of time commitment you're in for helps you plan your next move. Some people want to fast-track their certification over a few intense weeks. Others want to pace it out while working or traveling. And some just want to make sure they’re not wasting time (or money) on a course that looks good on paper but teaches very little in practice.
Let’s unpack what “120 hours” really means, how long different course types take, and how to pick the right pace for your lifestyle and goals.
What Does “120-Hour TEFL” Actually Mean?
You’ll see it everywhere: “120-hour TEFL course.” But what does that number really refer to?
In the TEFL world, course names usually reflect the estimated study time it takes the average person to complete the material. So a 120-hour course should offer enough content—readings, assignments, quizzes, videos, and practice activities—to reasonably fill about 120 hours of learning. It’s not tied to calendar days, and it’s definitely not the same as showing up to a physical classroom for 120 hours straight.
That’s why a self-paced 120-hour online TEFL course might take one person four weeks and another person four months. The number is there to help set expectations for how comprehensive the course is—not how fast you’ll finish it.
But here’s the catch: not all “120-hour” TEFL courses are created equal. Some budget platforms slap the label on a course that barely has 20 hours of material. These often skip grammar instruction, real assessments, or practical teaching techniques. Reputable providers, on the other hand, build out the full 120 hours with meaningful content and tutor support—so you’re actually learning, not just ticking boxes.
If you’re serious about teaching abroad or online, stick with a course that earns its hours. Employers can often tell the difference.
Course Types and Time Commitment
How long your TEFL course takes depends heavily on the format you choose. Some people want the flexibility to study after work or on weekends, while others want to knock it out in one go. Here’s how the main types compare:
Online TEFL (Self-Paced)
These are by far the most popular option—especially for people working or traveling. You can log in anytime, study at your own pace, and finish on a schedule that fits your life. Some people power through in a month. Others chip away slowly over 3–6 months.
- ✅ Best for flexibility and affordability
- 📍 Often includes quizzes, written assignments, and optional teaching practice
- 🕐 Time commitment: 3 weeks to 6 months, depending on your pace
In-Person or Hybrid TEFL Courses
These are more structured, with set start/end dates, daily classes, and real-time teaching practice. A hybrid model might combine online theory with an in-person practicum.
- ✅ Best for people who want live feedback and in-class experience
- 📍 Often required for CELTA or more formal ESL settings
- 🕐 Time commitment: 4–6 weeks full-time
Level 5 and Advanced TEFL Courses
These are more in-depth and often regulated by formal bodies (like Ofqual in the UK). Expect additional modules, assessments, and a deeper academic focus. They’re ideal for anyone aiming for higher-end jobs or who wants to stand out.
- ✅ Best for competitive job markets or visa-qualified roles
- 📍 Includes grammar deep dives, teaching methods, and feedback
- 🕐 Time commitment: 2–6 months, depending on the provider and your pace
Average Completion Times (Real Examples)
Let’s get specific. While every learner is different, here’s what most people experience:
-
🎯 Standard 120-hour TEFL (online, self-paced):
→ 6–12 weeks is typical
→ 3–4 weeks if you're studying full-time
→ 2–6 months if you're balancing it with work, travel, or school -
📅 Most reputable TEFL providers give you 6–12 months of course access, so you’re not rushed.
-
⚠️ Red flag: If a course claims you can finish a 120-hour TEFL in 2 or 3 days, it’s not legit. Real TEFL courses take time, especially if you want a certificate that employers respect.
Ultimately, you control the timeline. Just make sure you’re choosing a provider that gives you the flexibility—and quality—you need to succeed.
Factors That Affect How Long It Takes
Even with a "120-hour" label, the actual time it takes to complete your TEFL course can vary a lot from person to person. Here’s what makes the difference:
Study Habits
Are you someone who knocks out a module every evening—or do you cram on weekends? A steady, consistent pace tends to lead to better results (and less stress), but everyone works differently.
Learning Style
Some people fly through grammar modules; others need extra time to absorb tricky concepts like tense usage or phonology. Whether you're a visual learner, a note-taker, or someone who prefers video lectures, your style affects how quickly you move through the content.
Course Structure
Not all TEFL courses are built the same:
- Modular setups let you move around and skip ahead—faster for self-starters.
- Linear courses guide you step-by-step, which can be great for structure but slower overall.
- Some providers have assignments that require tutor feedback, which adds waiting time.
Personal Schedule
Life happens. Whether you're juggling a full-time job, traveling, parenting, or other commitments, the time you can devote each week plays a major role. That’s why flexible, self-paced options are so popular among first-time TEFL students.
Do You Really Need 120 Hours?
In almost every case, yes. A 120-hour TEFL certificate is the industry standard—it’s the minimum most employers and visa authorities accept.
Why 120 Hours Matters:
- ✅ Meets global expectations: Most schools and online platforms list 120 hours as their baseline requirement.
- ✅ Visa compliance: Countries like South Korea, China, Thailand, and Vietnam often require 120 hours for visa eligibility.
- ✅ Looks legitimate: Anything less tends to raise red flags, especially among reputable employers.
When More Than 120 Hours Might Help:
While 120 is enough for most teaching jobs, you might consider 180, 250, or even 300+ hours if:
- You don’t have a degree and want to boost your qualifications
- You're applying to competitive markets or higher-end schools
- You want to specialize in areas like Business English, Young Learners, or Online Teaching
Remember, though: more hours ≠ better if the course itself is low quality. Focus on well-reviewed, accredited programs before signing up for anything that sounds bloated or vague.

Can You Work While Taking a TEFL Course?
Absolutely—and that’s one of the biggest reasons people choose online, self-paced TEFL courses. You can study from anywhere, at any time, and fit it around your current schedule.
Tips for Balancing Work and Study:
- Set a Schedule: Block off regular hours—like 1 hour every evening or 4 hours every weekend—to stay consistent.
- Pick a Realistic Goal: Want to finish in 8 weeks? Great. Write that down, set milestones, and track your progress.
- Use the Support Tools: Choose a course that includes tutor guidance, automated progress tracking, and downloadable resources. These small tools make a big difference in keeping you motivated.
Whether you're teaching part-time already, working full-time, or bouncing between hostels, the flexibility of a TEFL course means you can keep moving forward—at your pace.
Is It Possible to Finish TEFL in Less Than a Month?
Yes—but it depends on the course format, your availability, and your motivation.
If you’ve got time to study full-time (think 4–6 hours a day), it’s completely possible to finish a 120-hour course in under four weeks. Some people even do it in two. But just because you can doesn’t always mean you should.
If you’re brand new to teaching, grammar, or lesson planning, rushing through the material might leave you feeling unprepared when it’s time to teach. TEFL isn’t just about checking off modules—it’s about building real confidence in the classroom or online.
Take the time to absorb the material, reflect on the practice activities, and reach out to tutors if something doesn’t make sense. The more solid your foundation, the easier it’ll be to land a job and thrive in your first few weeks of teaching.
After the Course: How Soon Can You Get a Job?
Here’s the exciting part—many schools and online platforms don’t even wait for your certificate to be in hand. You can start applying while you’re still wrapping up the course.
In fact, around 80% of new TEFL teachers find work within 2–3 months of finishing their certification. Some even have job offers lined up before they graduate.
High-Demand Markets Include:
- Asia (Thailand, Vietnam, China, South Korea, Taiwan, Japan, Cambodia)
- Latin America (Mexico, Colombia, Costa Rica)
- Online Teaching Platforms (Preply, Cambly, AmazingTalker)
To speed up your job search:
- Build a simple but polished CV focused on teaching
- Practice a short demo video or lesson
- Join job boards or apply to agencies that work with new teachers
Final Thoughts: Focus on Learning, Not Just the Clock
Getting TEFL-certified isn’t just about finishing fast—it’s about being ready. Ready to lead your first class, ready to explain English clearly, and ready to handle curveballs with confidence.
Yes, the time it takes to complete your course matters. But what matters more is how prepared you feel once it's done.
Pick a course that fits your lifestyle, but also gives you the training and support to succeed. Whether you finish in a month or stretch it over six, make it count. The real adventure starts when you step into the classroom—wherever in the world that may be.
