vietnam and thailand, the upgrade question
the short answer
For Vietnam, a 120-hour course covers most language-centre jobs and Level 5 is a nice-to-have for bilingual schools or crowded cities. For Thailand, Level 5 matters slightly more because it strengthens the teaching-licence waiver paperwork and opens international and kindergarten roles. Neither market strictly requires it, but Thailand rewards the upgrade a bit more consistently than Vietnam does.
| Vietnam hiring bar | 120 hours accepted at most language centres |
|---|---|
| Thailand hiring bar | 100-120 hours tied to licence waiver system |
| Where Level 5 helps most | Bilingual/international schools in both countries |
| Where it barely matters | Standard local language centres, either country |
| Cost difference | 120-hour from ~£149; Level 5 from ~£299 |
| Time difference | Usually 1-3 extra weeks of coursework |
| Combined verdict | Level 5 helps Thailand slightly more than Vietnam |

Local language centre vs bilingual/international school changes the answer.
Covers most Vietnam centres and standard Thai schools.
Worth it for Thai licence-waiver strength or Vietnam bilingual schools.
Both markets hire fairly continuously with seasonal peaks.
Common in both countries regardless of course level.
Vietnam peaks Aug-Sep and after Tet; Thailand peaks May and November.
Vietnam's language-centre market, especially in Hanoi and Ho Chi Minh City, hires heavily on a 120-hour accredited certificate, and that's genuinely enough for the majority of no-degree teaching jobs at local centres. Level 5 mainly earns its cost back in Vietnam if you're specifically targeting bilingual schools, better-paying centre chains, or trying to stand out in the more saturated HCMC market — it's an edge, not a requirement.
Thailand ties TEFL certification more directly to its teacher's licence waiver system, and some schools — particularly government programme placements, international schools, and kindergarten roles — prefer to see a course with an assessed or practical component rather than a bare-minimum online certificate. That gives Level 5 a slightly stronger, more consistent case in Thailand than in Vietnam, even though a 120-hour course still clears the basic waiver requirement for most standard local schools.
If you're choosing one course to use in both countries — a common plan for teachers who want to keep options open across Southeast Asia — Level 5 is the safer single investment, since it clears the bar comfortably in both and gives you access to Thailand's international and kindergarten niche plus Vietnam's bilingual-school tier. If your budget is genuinely tight and you're committing to standard local language-centre work in either country, a 120-hour accredited course remains a legitimate, honest choice — just don't expect it to open every door in Thailand's stricter school types.
what people actually ask
No, neither country strictly requires it — a 120-hour accredited course clears the standard hiring bar in both. Level 5 is an upgrade that helps with bilingual schools in Vietnam and international/kindergarten roles in Thailand, not a legal minimum.
Thailand, slightly, because its teacher's licence waiver system and some school types prefer a course with an assessed component, which Level 5 typically has. Vietnam's language-centre market is more relaxed about this specific point.
Yes, a single accredited Level 5 course works across both markets and is a sensible choice if you're not sure yet which country you'll end up in, or plan to work in both over time.
It can limit access to international schools, some kindergarten programmes, and stricter government placements, though it's fine for most standard local language schools. Check the specific school type you're targeting before deciding.
Generally no — CELTA is priced for a different tier of job than typical Vietnam or Thailand language-centre and bilingual-school roles, and neither market's mainstream hiring expects it. Save it for a later move into Europe or the Middle East if that's on your radar.
