The most important part of your TEFL course has to be its certification. There are different levels of TEFL certification to choose from. With the rise in the international market for online ESL teaching jobs and with over a million people enrolling for it, the competition has never been easier out there. But with the right course and the right choice of certification, you might just crack it and be out there living your dream.

Now because you’re here, I assume you already did your part of the research on TEFL and are firm with your decision but the problem rises with the right choice of certification for your course. No worries because we are here to explain all the different levels of TEFL certification.


But before let us understand what is TEFL certification and why is it the most essential part of the course:

TEFL known as Teaching English as a Foreign Language is a course that trains you as an instructor and allows you to teach English in non-native countries to the speakers of the foreign language. For example, teaching English to Korean people in Korea.

TEFL courses qualify you to be able to teach English online with or without a degree but here’s where the certification comes in. There are certain International TEFL Standards that must meet your course and the certification.

But as per the International Standards for English language teaching, the certificate must meet 120 hours of the course training period.

International Standards for TEFL Certification:

  1. The minimum hour requirement for any TEFL course is minimum of 120 hours of training. Numerous TEFL course providers train you for as minimum as 20 hours or 60 hours for the beginners and it might seem affordable. 

But as per the International Standards for English language teaching, the certificate must meet 120 hours of the course training period.

  1. The course must include a minimum of 6 hours of live in-class teaching practice to authentic English students. The 120 hours TEFL course training often consists of 100 hours of online teaching practice and 20 hours of in-class live teaching practice. However, this may not always be the same and may vary from course to course

  1. All your instructors or trainers should be highly professionals and must have either of the following qualifications: Diploma in TEFL or Diploma in TESOL/ DELTA/ a Masters degree. Your instructor or trainer must have at least 8 years of minimum experience in Training, Linguistics and ESL.

  1. The instructor must provide you with the training resources and materials that should include: Learning and language skills and awareness, classroom management, phonetics and methodologies.

  1. The most important part of your TEFL course is its accreditation. The accreditation must be verified with the university and the standards set. The accreditation provided with your course may have a quality assessment and assurance but, it may not always prove to be suitable.

This set of standards further decide the different levels of TEFL certification. Which brings us to our title and the reason you are here.

Levels of TEFL Certification:

The Office of Qualifications and Examinations Regulation was established in 2010. Ofqual is a UK government-regulated body. Ofqual has a standardized framework of qualification and assessment. The qualifications for Ofqual includes different levels of Tefl certification based on learners level, calculation of hours, quality assurance.

There are a variety of levels of TEFL certification based on their difficulty level. Higher the course level more the level of difficulty, work and time for completion of your work.

Level 0/ Unregulated:

Level zero TEFL qualification or unregulated TEFL course is a basic entry-level course that only covers basic knowledge about teaching skills. Most of the unregulated TEFL courses do not qualify under the Ofqual set of standards. These TEFL courses are the cheapest and hence tempting to go for but it does not cover the standards for a TEFL course.

Level 1:

Level 1 is a grade 3 to 1 under GCSE ( The General Certificate of Secondary Education ) which is an academic qualification in a particular subject. A GCSE grade 3 is a minimum pass grade under England, UK grading qualification. This level also covers a minimum key teaching and learning skill and may qualify for level 1 NVQ ( National Vocational Qualification).

Level 2:

Level 2 is a grade 4 to 9 under GCSE ( The General Certificate of Secondary Education ) which is an intermediate pass. At level 2 you learn language and learning skills, enhance your ability to perform a task and also get supervised. This qualifies you for a level 2 NVQ ( National Vocational Qualification ) and OCR ( Optical Character Recognition ).

Level 3:

A Level 3 TEFL qualification is the most cost-effective certification that covers all the set of standards that fall under Ofqual quality assurance. Level 3 is also equal to AS and A level certification and recognised all over the world. This level covers the minimum training hours requirement that is 120 hours to  320 hours. With level 3 certification you can get both a job abroad and also get to volunteer for it. 

A level 3 course covers in detail your knowledge, teaching and language skills, lesson planning strategies and methodologies to apply your teaching. It also upskills classroom management skill. Online live teaching practice and supervision is done. Level 3 certification is a great choice for entry-level or beginners to qualify for teaching or ESL jobs online abroad.

Some of the recognized sites that provide Level 3 TEFL courses are:

1. i-to-i :

I-to-i has over 25 years of experience in training students to teach English abroad. They provide both level 3 and level 5 TEFL qualification. All their Level 3 courses have the UK government stamp of approval.

Level 4 TEFL course covers 140 hours of training period which includes 20 hours of practical teaching experience. The course includes lexis and phonology, grammar awareness, lesson planning and classroom management.

Level 4 is more preferable when it comes to English teaching opportunities in competitive international markets. A Level 4 certification qualifies for an HNC ( Higher National Certificate ), level 4 NVQ ( National Vocational Qualification ).

Level 5:

The most highly recognised and preferred certification worldwide is a Level 5 qualification. A level 5 TEFL certificate meets the same assessment and regulatory standards as CELTA and Trinity CertTESOL qualifications. Level 5 TEFL certification is best for people who wish to apply for a high level of teaching positions abroad or online. Although this level course is a bit expensive it will help you meet your higher salary expectations.

The level 5 course includes 160 hours to 300 hours of training. The TEFL level 5 course will include an in-depth study of vocabulary and pronunciation, language skills, phonetics. The course also covers strategies and methodologies for classroom management and lesson planning.
