i to i Tefl Certification Review

A Full Review of i-to-i TEFL 180-hour TEFL Certification Course

I-to-I TEFL History and Accreditation

i-to-i TEFL is one of the longest-operating TEFL certification providers in existence, having been established in 1994. They were also one of the first companies to establish an online certification program at the beginning of the millennium. To date, over 182,000 teachers have gained their TEFL certification through i-to-i TEFL by completing one of their online or in-person TEFL courses.

Note: This review is based on our own audit of the i-to-i TEFL 180-hour certification course. Like our other TEFL course reviews, we have personally reviewed the course and feel confident that this information will help you decide if obtaining your TEFL Certification from i-to-i TEFL is the best choice for you.

Their courses are regulated by the Office of Qualifications and Examinations Regulation (Ofqual), the United Kingdom’s regulating body for qualifications, exams, and tests. They also hold an accreditation from the Open & Distance Learning Quality Council (ODLQC), an independent body for overseeing education and training standards and originally set up at the request of, and with support from, the UK Government in 1968.

Their Ofqual Level 5 certification, for which we are recommending, means that the course meets minimum standards to make it equivalent to a diploma of higher education.

Course Basics

The 180-hour online-only course is meant to introduce you to the basics of teaching English as a foreign or second language and to prepare you for classroom teaching. The course can be taken at your leisure, so long as you complete it within 180-days of purchasing it. 

There are ten units to the course which are each broken down into different sections further elaborating on the primary topic of the unit. Within each unit are multiple tests which you must periodically complete in order to ensure understanding and retention of the information presented. 

The units are:

Unit 1: Introduction to TEFL

Unit 2: Initial Lesson Planning

Unit 3: Structuring Your Lesson

Unit 4: Making it Work in the Classroom

Unit 5: Teaching Vocabulary

Unit 6: Teaching Pronunciation

Unit 7: Teaching Grammar

Unit 8: Teaching Young Learners

Unit 9: Teaching the Four Skills

Unit 10: External Resources and Next Steps

Aside from the information in each unit, there are also links to supplementary information which you can read to further your understanding of teaching ESL and EFL. Each course ends with a test that must be passed in order to proceed to the next unit. Tests must be passed with a score of at least 75% in order to proceed. There is also a lesson planning assignment that must be completed in order to pass the course and obtain your certification.

What to Expect

You can expect to be challenged. The 180-hour certification program is extremely detailed and the information presented in-depth. We have been through numerous certification programs for the purpose of review and this is one of the most information-dense programs that we have come across. 

Expect this course to take time to get through, especially if you are completely new to teaching English as a second or foreign language. If you are new, you will most likely have to review each unit more than once in order to fully absorb the information and pass the test at the end of each unit.

You can expect that at the end of the course, you will be fully prepared to plan and teach your first class. Great importance is placed on understanding your students and their individual needs and taking this into consideration when you are creating lesson plans which should prepare you for any situation you find yourself in. You should also develop an understanding of different teaching styles and techniques which you can employ in various settings. 

Upon completion of the course, you will receive a certification which you can present to employers online and abroad.

Who Should Take the Course


This course is a great option if you are planning on teaching online or if you want to teach abroad in countries across Asia, Europe, and the Americas. The exception to this will be Middle Eastern countries. If you are planning on teaching in the middle east, you will need to take one of the combined courses which offer both the online learning as well as an in-class component (often referred to as a practicum). 


If you are completely new to teaching English as a foreign or second language this is a great course as it provides extensive background information on both the development of the industry as well as teaching grammar, pronunciation, and vocabulary, and how to prepare lessons for different levels of students. Teachers with more experience should also benefit from the course, even if it is just review.


The Ofqual Level 5 certification program is regularly priced at $1495, although i-to-i TEFL regularly discounts their courses to an affordable price range between $400 – $600.
