Start your teaching career for the prestigious Trinity College London CertTESOL by completing our fully online course from the comfort of your own home, or combine it with teaching in Thailand on our blended course.
Our 200-hour course (130 hours of guided learning and 70 hours of self-study), gives you training in effective, communicative language teaching methodology for both online and face-to-face teaching. The first stage of our online component allows you to set a daily study timetable to suit your lifestyle. You can then decide whether to complete all of your teaching practice online or join one of our onsite courses to complete your teaching practice in a real classroom environment in Thailand.
The Trinity CertTESOL is a benchmark qualification in the TEFL industry. It is accepted by employers worldwide as a professional qualification and opens teaching doors to you worldwide.

Teaching Practice in real classrooms on our blended course
As teachers we appreciate that hands on teaching practice in the environment of a real classroom is a key skill for new teachers to experience. While your teaching practice can be done fully online without needing to travel to Thailand, our blended courses allow teachers the opportunity to experience the thrill of a live, authentic classroom, either at a school or business organization here in Thailand. Gaining valuable experience in a live classroom will also help with acquiring the confidence to teach in real classrooms once you complete the course.

The Trinity CertTESOL (Ofqual Level 5) is recognised globally as a seal of quality for language teaching. The stringent checks and moderation process undertaken by Trinity College London for each course ensures the ongoing quality.
Better job prospects
The Trinity CertTESOL is recognised and accepted by employers around the world including the British Council and International schools.
