How do I get my first TEFL qualification?

If you are new to TEFL, you need to get your initial TEFL certificate. If you are confused about the terms like TEFL/CELTA/TESOL, check out our handy explainer, but rest assured that the CELTA is the number 1 qualification because it is certified and moderated by Cambridge university.

There are many TEFL certificates available worldwide and for TEFL Thailand – we offer the original and most recognized, the Cambridge Certificate in Teaching English to Speakers of Other Languages (CELTA). This was originally developed by International House back in the 1950’s and is now the most widely known TEFL certificate, opening the door to teaching jobs in hundreds of countries around the world. For more information on the Cambridge CELTA, you can visit the Cambridge CELTA site.

According to a study in 2018, three out of four English language teaching jobs ask for the CELTA (source).


People who are new to teaching can take the CELTA, as well as those teachers, native speakers and non-native speakers, who have some experience but want the validation and professional training of an internationally recognized teaching qualification.

New teachers may also be interested in…

Our Grammar Refresher course – native speakers grow up with the language but don’t learn all the grammar rules. As a teacher, it’s important to have some understanding of how the language works so you can help students with their problems. If you are about to take the CELTA course this is also a great opportunity to meet the trainers and other trainees in a relaxed atmosphere before starting the course.

Our Introduction to Teaching Young Learners – there are a lot of jobs that involve teaching children and teenagers so we have developed a specialized 2-day course to give you the key techniques and activities to cope with teaching younger learners. This course is provided for free with our CELTA course.

How can I develop my teaching further after the CELTA?

If you’ve completed the CELTA or a similar TEFL certificate course, you may be interested in the Cambridge Delta – this is a diploma level course for teachers with at least 2 years’ classroom experience. It involves observed teaching practice as well as academic research and essay writing.

If you are not quite ready for the Delta, think about the popular IH Certificate in Advance Methodology. You can learn more about the underlying theories behind TEFL teaching and apply new ideas to your own teaching to take your classroom skills to the next level.

If you want to specialize in teaching Young Learners, build on your knowledge from the CELTA by doing the IH Certificate in Teaching Young Learners and Teens. This course, accredited and moderated by Cambridge Assessment, is now the leading certificate of its kind, a 2 week course with observed teaching practice with different age groups. (This course has replaced the old CELTA YL extension certificate).

Experienced non-native teachers of English who are not ready to do the CELTA may be interested in the Cambridge Teaching Knowledge Test course which prepares you for the TKT exam.
