|A TEFL course in Bangkok is one of the best ways to prepare for a teaching job in Thailand. Bangkok is home to many of Thailand's leading schools, language centres and teacher training providers, so you can gain real classroom experience before you apply for paid teaching positions.
All course prices are set and payable in Thai Baht (THB). USD and GBP figures are approximate conversions based on exchange rates at time of publication (July 2026: 1 USD = 33.5 THB | 1 GBP = 44.75 THB). Check current rates before budgeting.
An accredited in-person TEFL course in Bangkok typically runs over four weeks, includes supervised teaching practice with real students and leads to a qualification recognised by schools across Thailand. This guide explains what to look for, how accreditation works, why teaching practice matters and what a course costs.
TEFL stands for Teaching English as a Foreign Language. A TEFL course prepares you to teach English to students whose first language is not English. It is the standard qualification for English teaching jobs in Thailand, across Southeast Asia and around the world.
During an in-person course you should learn:
The best courses also include real teaching experience in genuine classrooms, not just theory. For an overview of what teaching in Thailand involves, see our Teaching in Thailand guide.

For most teaching jobs in Thailand, a TEFL or TESOL qualification is the right choice. Thai schools treat the two as interchangeable. CELTA is a strong qualification but designed for teaching adults in private language schools, not children in mainstream schools. Its teaching practice is with adult learners, so it does not prepare you for the kindergarten, primary and secondary classrooms where most Thai teaching jobs are. CELTA also costs more and has very few centres in Thailand.
See our FAQs for teachers for more on what Thai schools expect from applicants.

The biggest difference between TEFL courses is the amount of real teaching experience included. Some online courses contain no classroom practice at all. A good in-person course gives you the chance to:
Teaching practice is often the first thing schools ask about at interview. A course that includes observed teaching in real Thai classrooms gives you a clear advantage over candidates who trained online.
Before you enrol, check who awards or accredits the qualification. Questions to ask:
A TQUK Level 5 Certificate is regulated by Ofqual, the official qualifications regulator for England, which means it is externally quality-checked rather than self-issued by the training provider.
