The Best 160+ Hour TEFL Certification Courses in 2025


A man jumps in the air smiling on the Great Wall of China.

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?

Read on for a list of highly-rated level 5 TEFL and TESOL courses that give you a substantial boost not only in the classroom but also in the TEFL industry!

Why choose a 160+ hour course over a 120-hour course?

TEFL and TESOL courses come in all shapes and sizes. The standard course length is 120 hours, so why dedicate more of your precious hours towards your qualification?

  • Greater insight: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.
  • Specialized training: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.
  • Resume booster: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.
  • Accreditation: A 168-hour TEFL/TESOL course is equivalent to a UK level 5 qualification. That means it is also comparable to the CELTA and Trinity Cert TESOL teaching qualifications.

How did we pick these programs?

At Go Overseas, we want our community members to have the resources they need to find the program that best fits their travel goals! To determine the best programs, we considered the overall rating of each program and compared the verified, recent reviews left by community members. The more positive, highly-rated reviews there are, the more confident we feel to give our stamp of approval!

Lastly, we used our own industry knowledge to ensure we’re recommending programs that are vetted both by you, the community members, and us, the experts, so that we feel confident the programs included are the best of the best!

1. Premier TEFL

Best for online teaching practice

Type of study: Online with live sessions
Price point: $409
Requirements: You must be a native or fluent (C1 level) English speaker
What’s included: 26 hours of optional live classes over Zoom, specialist courses including business English and young learners, 3 eBooks, personal tutor support, access to study app, job board access, job coaching seminars

✅ Pros:

  • Premier TEFL teaches you to plan lessons that reach your students — learn how to utilize apps they use like TikTok, YouTube, and Spotify.
  • Two specialist courses are included with your tuition.

❌ Cons:

  • Live teaching sessions are held on specific days and times which may be hard for some students to plan for.
  • You only have access to the materials for 6 months after purchase so this isn’t for learners who plan to study over an extended period of time.

Premier TEFL’s 310-hour TEFL Advanced Diploma offers interactive and dynamic lessons from videos to podcasts and quizzes, with the goal of helping you expand your learning. This 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 according to its framework.

As a self-paced course, you can work through the material at your pace with six months course access. Modules cover the principles of TEFL to lesson planning, classroom resources, and much more. The 10 hours of teaching practice will help you stand out from other teachers with no practicum experience. Additionally, an academic tutor will answer any queries and provide expert guidance on securing your TEFL job.

“I selected Premier TEFL and am so glad that I did because it has so far been an excellent platform. The modules are clear and well organized, and the customer service is incredibly helpful.”

The hybrid course allows you to travel to a city in Europe, South Africa or even right here in the US where you’ll get 10 hours of real teaching practice with expert feedback. Doing your teaching practicum overseas will give you a look into TEFL as a career right where it’s happening. Accredited by Ofqual (UK) and DEAC (US), this course is another level 5 qualification.

“I’ve learned a lot of valuable information that played a large role in my getting a job shortly after qualifying. I would happily go back to the TEFL Academy to further my studies with their more specialised programs.”
