Earning a TEFL certificate is your first step to career freedom, opening the door to traveling and teaching in practically any country in the world. But before you jump head first into verbs, vocabulary, and visualizing yourself kicking back on a Thai beach after a day’s teaching, there’s an important decision to be made: exactly how many hours of TEFL course study should you go for?
Why choose a 160+ hour course over a 120-hour course?
TEFL and TESOL courses come in all shapes and sizes. 120 hours is the standard length of most courses, generally because this is the traditional amount of contact time if you sit the internationally-recognized CELTA course. So why dedicate more of your precious hours towards your qualification?
- More hours of study means you can take a deeper dive into important grammatical points which can be tricky to explain even for native English speakers.
- You can gain more thorough and comprehensive training in areas beyond the traditional nuts and bolts of TEFL tuition, such as business English, teaching young learners, and preparing students for official English language exams.
- You may find that these extended courses help you to stand out when compared to the standard 120-hour TEFL certificate every other teacher is applying with on their resume.
With that in mind, we pulled together a list of the most highly-rated TEFL and TESOL courses that give you a substantial boost in the number of hours you'll spend on the course.

If you’re an interactive learner, the 310-hour TEFL Advanced Diploma from Premier TEFL is what your TEFL training dreams are made of. It prides itself on the dynamism of its lessons, which run the full gamut from videos through to podcasts and quizzes, all with the goal of helping you expand your learning.

The 10 modules are comprehensive, to say the least, covering everything from the principles of teaching English as a foreign language, to lesson planning and even how to make the most of resources in your classroom. The 10 hours of teaching practice will help you stand out from other teachers with no practicum experience.
You will also be assigned an academic tutor who’s on hand via email for any queries and can give you expert guidance on securing that post-course job.
This 310-hour TEFL certification is regulated by Ofqual, a governmental body from the UK that oversees exams and qualifications, and is equivalent to both the CELTA and Trinity CertTESOL qualifications.
