TEFL certification – is 120 hours actually enough or do I need a 180-hour course for Southeast Asia?
I've been going back and forth on this for three months now. I want to teach English abroad, probably in Southeast Asia to start, and I keep getting different answers about whether a 120-hour TEFL certification will limit my job options compared to a 180-hour program. The price difference is significant — the 180-hour courses I've looked at run about $400–$600 more, which matters when I'm also budgeting for the actual move.
I'm not looking to teach in South Korea or Japan where some employers are pretty specific about accreditation and hour counts. My target is Thailand or Vietnam, and from what I've read on expat forums, most language centers there will hire with a solid 120-hour cert from a recognized provider. What I haven't been able to nail down is whether the practical teaching component hours matter as much as the total count — some 120-hour courses have 20 hours of observed teaching practice and some have only six.
I've been teaching English conversation to non-native speakers at a community center for about two years as a volunteer, so I'm not coming in completely cold. I can explain grammar concepts and I understand lesson planning basics. What I'm less sure about is whether the certification content will actually teach me anything I can't figure out on the job, or if the value is purely the credential for visa and hiring purposes. Honest takes from people who've been through this process would be genuinely useful.
If you want to move into better-paying university or corporate English training roles later, some of those do look at the hour count and accrediting body. Starting with 120 is fine but just know you might want to add a CELTA or Delta eventually if you plan to stay in EFL long-term as a career.
The credential is mostly for visa and employment paperwork in Southeast Asia. I've been teaching in Vietnam for two years on a 120-hour cert and never had it questioned once. The actual skills you develop depend way more on your first six months in the classroom than anything in the course itself.
Your two years of volunteer teaching experience will carry you further than the extra 60 course hours. Mention it prominently in your applications — directors at language centers care more about real classroom experience than whether you did 120 or 180. Just make sure your cert is from a recognized provider and you're good to go.
For Thailand and Vietnam specifically, 120 hours is enough to get hired at most private language centers. The observed teaching practice hours matter more than the total count in my experience — I had 20 hours of practicum in my 120-hour course and felt much more prepared than friends who did 180 hours with minimal supervised practice time.
Honestly, I went through the exact same spiral before settling on 120 hours, and what pushed me over the edge was realizing that most employers in Thailand and Vietnam care way more about your classroom hours and methodology background than the total certification hours. The 180-hour programs often just pad the count with extra practice teaching or elective modules that you can get on the job anyway. I'd say if you're going to prep seriously, focus on actually understanding the grammar concepts — not just what the right answer is, but why the other three options are wrong. That clicked for me when I started drilling with free tefl vocabulary terminology resources and forcing myself to explain each distractor out loud.
120 hours opened doors for me in Cambodia and got me interviews in Vietnam without any pushback. The places that require 180 are usually international schools with higher pay, but you can always add a specialized module later once you're already in country and know what you actually need.
Honestly I was in the exact same boat last year and almost just picked the cheapest 120-hour course I could find. What I ended up doing was going with a 120-hour accredited program, and I'm now teaching in Vietnam with zero problems getting hired. The 180-hour thing gets talked up a lot but in my experience most Southeast Asian schools just want to see that you're TEFL certified from a recognized provider -- the hour count mattered way less than I expected it to.
That said, I won't pretend the prep wasn't rough. There's a lot more to it than I thought -- lesson planning, phonology, grammar terminology I hadn't used since high school. I almost quit about halfway through because I felt like I wasn't retaining anything. Kept pushing, did practice tests over and over until the material actually clicked, and passed on my first attempt. Don't overthink the 120 vs 180 debate too much, just make sure whatever course you pick has solid practice materials and you actually use them.
I went through this exact debate last year before doing my TEFL in Vietnam. Honestly, the 120-hour cert got me hired at three different schools in Ho Chi Minh City without any issues. What I'd say matters way more than the hour count is how you study for the cert itself -- I didn't just memorize the right answers, I made a point of understanding why the wrong options were wrong, which made a huge difference when actual classroom situations came up that weren't in any practice material. The free tefl vocabulary terminology questions I found online helped a lot with that because they explained the reasoning behind each answer.
The 180-hour courses are mostly marketing. A few premium schools in Bangkok or Hanoi might list it as preferred, but recruiters I talked to said they care more about your practicum hours and whether you can actually explain grammar rules on the spot. Save the money, get the 120-hour cert from an accredited provider, and spend the extra cash on your first month's rent in-country.
I was in the exact same boat last year, working full-time and trying to squeeze in TEFL study on weekends and lunch breaks. I went with a 120-hour course and honestly it wasn't the limitation I thought it'd be — most schools in Thailand and Vietnam didn't even ask about hours, they just wanted to see the certificate and that I'd done some practice teaching. What helped me actually pass the grammar and methodology sections was drilling with free tefl vocabulary terminology quizzes online, because the jargon trips you up if you're not used to it.
That said, if you're targeting international schools or university positions, the 180-hour course does open more doors. But for the standard language school market in Southeast Asia? 120 hours is plenty. You'll get the job on your personality and interview more than anything else.
