Get TEFL Certified for Thailand: Accredited 120 Hour Course
by Premier TEFL

Program Overview
Schools in Thailand typically ask for a bachelor's degree and a TEFL certificate of at least 120 hours before they will sponsor a Non-Immigrant B visa and work permit. Premier TEFL's Accredited Online TEFL Course is 120 hours, so it meets the standard most Thai employers set.
The degree matters because the work permit process and the Teachers' Council of Thailand teaching license are usually tied to it, and schools arrange that paperwork after you sign a contract. Native level English and a clean background check are expected.
The 120 hour course covers lesson planning, classroom management, and teaching grammar and skills to young learners and adults. If you want a stronger profile for international schools, the Level 5 TEFL Diploma, Ofqual reference 610/1572/6, is the step up.
You study fully online at your own pace with tutor support, receive a digital certificate on completion, and get lifetime job assistance as a graduate. Most people finish in 2 to 6 weeks, whether in Bangkok, Chiang Mai, Phuket, or at home before you fly.
Enroll online today and start the same day, or ask the team which course fits the Thai roles you want.

FAQs
Frequently Asked Questions
Get answers to all the most common questions about Premier TEFL.
Do I need to speak Thai to teach English in Thailand with this TEFL?
No. Schools in Thailand expect English only instruction in the classroom, and many actively prefer it so students get full immersion. This TEFL course trains you to teach using gestures, visuals, modeling, and simple instructions, so you can manage a class with no Thai at all. Learning a few basic phrases will still help with daily life, local colleagues, and settling in, and many teachers pick up conversational Thai once they arrive.
What qualifications do I need to join this 120 hour TEFL course?
You need to be 18 or over and have a good level of written and spoken English. A degree is not required to enroll or to earn the certificate. Keep in mind that most schools in Thailand, and the work permit process, usually expect a bachelor's degree for full time teaching roles. If you do not hold a degree yet, you can still certify now and use the qualification later, online, or in other countries with different entry rules.
How long does it take to complete the 120 hour TEFL course online?
Most people complete the course in 2 to 6 weeks. It is fully self paced with 24/7 online access, so you can move faster if you study full time or spread it out around work, college, or travel plans. There are no fixed class times to attend. Many students finish before they fly, while others complete it after arriving in Thailand, alongside the job search. Your digital certificate is issued as soon as you pass the final module.
Can I use this TEFL certificate outside Thailand in other countries?
Yes. The certificate is not tied to Thailand. The 120 hour standard is the benchmark many employers use across Asia, Latin America, and Europe, and it is also widely accepted by online teaching platforms. Each country sets its own visa and degree rules, so check those for your target destination. If you plan to move between markets or apply to international schools later, the Level 5 TEFL Diploma is a useful upgrade to consider.
Does the TEFL program include job support for teaching in Thailand?
Yes. Every graduate receives lifetime job assistance, including help with your resume, guidance on applying to schools and agencies in Thailand, and advice on interviews and contracts. We also explain the Non-Immigrant B visa and work permit steps so you know what paperwork to prepare. This course does not include a guaranteed placement, but the support stays available for as long as you need it, in Thailand and beyond.
