You can also expect to spend an additional 15-25 hours studying at your own pace via our online learning platform as well as interacting with your teaching colleagues and the training team through the discussion forum.Training to teach English online is a hugely fulfilling and enriching learning experience. You are being trained in the medium that is quickly becoming the most popular way of learning.


Throughout the course, you will attend practical training sessions online, led by our team of experienced CertTESOL tutors. During these training sessions, you will work in pairs and small groups and collaborate to make the most of the digital environment as well as providing transferable techniques and skills to use in physical classrooms. We believe in learning through involvement and many sessions will involve a workshop approach, where your tutor acts as a ‘facilitator’ rather than as a lecturer.


As you work through the modular content on our online platform, you’ll learn more about how to teach English. We will look at areas such as teaching methodologies, classroom management and how to appropriately select and adapt materials, amongst others.

Teaching practice is the heart of the course where you will teach real students in online classes, again via Zoom. You will teach a minimum of 6 hours and will work in small groups with a tutor who will guide you through each lesson encouraging increased independence as you move through the course. Your tutor will give you support planning your classes, observe the lesson and give you feedback. You will also spend a significant amount of time observing your colleagues, providing you with the opportunity to learn from each other.

Over the eleven weeks you will teach two levels giving you a broad set of experiences. You will also observe a minimum of four hours’ of lessons delivered by experienced teachers. These will include observing your tutors teaching the learners you’ll work with on the course, as well as pre-recorded lessons.

Teaching practice is where you grow as a teacher. By the end of the course you’ll feel confident in planning, delivering and reflecting on teaching. You’ll learn through both your tutors and your colleagues and put into practice what you learn.

Here at Active Language we’ve been training teachers on the CertTESOL course since 2005, so you’re in experienced hands.

The CertTESOL course will give you the skills and understanding you need to be confident of accessing good jobs and to be confident in any classroom in the world whether that is a physical or an online classroom.

Reputable organisations, such as the Britich Council, will only accept accredited teaching qualifications and the Trinity Certificate in TESOL is one of the two main qualifications which are accepted worldwide. There are a bewildering number of TEFL, TESOL or CELTA courses available and it can be difficult to see the differences between them.

TESOL stands for ‘Teaching English to Speakers of Other Languages’ and TEFL stands for ‘Teaching English as a Foreign Language’ they are generic names for the same thing rather than courses. The Trinity CertTESOL is an official qualification in TEFL provided by Trinity College London. CELTA is accredited by Cambridge University and enjoys equal standing to the Trinity CertTESOL. There are many other courses available too, though they vary wildly in cost, depth and, importantly, recognition within the profession.

With our Trinity CertTESOL you are getting international accreditation and an internationally recognised certificate you can be proud of as well as live tutor time in small groups, teaching practice with real students, a personal approach and on-going, career-long support.

The course is delivered and assessed through five units. The work for Units 1, 2, 3 and 5 is marked by your tutors and checked by a member of the Trinity moderation panel at the end of every course. The moderator externally assesses the work for Unit 4.

The units are as follows and rest assured, the tutors are here to help you every step of the way. A large factor in our high pass rate is the dedication and professionalism of the training team. The tutors’ job is to help you through the course.

Unit 1: Teaching Skills – assessed through your tutors’ evaluations, your teaching journal and reflections. Professional awareness and development are also evaluated as part of Unit 1.

Unit 2: Language Awareness – including grammar, lexis and phonology, assessed through a short exam. Our unique pre-course Language Awareness course will help you prepare thoroughly for the exam, as well as setting you in good stead for teaching grammar, lexis and phonology during your observed lessons.

Unit 3: Learner Profile – assessed through your evaluation of an individual learner’s strengths and weaknesses and a series of planned lessons for that learner.

Unit 4: Materials Assignment – assessed through a written rationale and evaluation of a piece of teaching material and an interview with the Trinity moderator

Unit 5: Unknown Language Journal – assessed through a reflective journal following four hours spent learning an unknown language.

As soon as you have completed the qualification you’ll be able to start teaching and with the CertTESOL, you should have your pick of the jobs.

There is a huge demand for English teachers both worldwide and online, it is a global growth industry in our connected, international world. Millions of people all over the world need to learn English and there are a huge number of different opportunities and different ways to work. We will help you during and after our courses to be successful in the TEFL job market.

There are two main ways teachers work, often combining the two. Many teachers work in private language schools, teaching adult or young learner students around the world. Others teach online and the online teaching market is the biggest growth area internationally within our profession. Teachers can work online from anywhere in the world, often having students from many different countries. Teachers are increasingly combining work in the physical classroom with online teaching to create their own ideal balance.

Upon successful completion of the course, you will be awarded the certified level 5-teaching qualification from Trinity College London that will give you the upper hand when searching for teaching positions worldwide. You’ll also receive a full Trinity Report to give your applications in-depth information. Your potential employers can also contact us for references.

Active Language is regularly contacted by employers specifically interested in reaching graduates from our courses. We collaborate with these employers and help you find a job by putting you in contact with them.

During the course you’ll receive guidance on how and where to apply for TEFL jobs worldwide and online as well as the opportunity to talk about your personal situation one-to-one. You’ll get tips on CV-writing to help you prepare a new resume that is fit for purpose, as well as interview preparation and links to jobs online. You’ll finish your course knowing everything you need to secure work.

Continuing professional development is an important part of teaching. As a graduate you automatically enjoy a year’s free membership to “the TEFL Development Hub”, a members-only online community where you can access insights from English teaching professionals around the world.

You can also take advantage of exclusive discounts on our teacher development courses to deepen your knowledge and qualification in a number of different ways. We are always here for you, it’s a commitment we make to all graduates, we pride ourselves on our ongoing relationships with the teachers we train.

You do not need to have a university degree, to speak English as your first language, to speak a foreign language, or to have any previous teaching experience.

To be considered for this course, you will need to:

– be at least 18 years old

– be educated to the standard required for entry into higher education

– be in good enough physical and mental health to deal with the demands of an intensive training course

– have a minimum C1 level of English. As your level of English will be assessed through the interview, we do not require you to hold a certificate but do accept the following: Trinity ISE III or GESE 10, Cambridge CAE or CPE, IELTS 7.5 or TOEFL 105. In fact, approximately 40% of our recent graduates from the CertTESOL speak English as a second or third language

– demonstrate your ability to cope with the academic demands of the course. There will be a short written assignment to complete following your interview

As a pre-service qualification, through the CertTESOL course you’ll learn how to teach English and so you don’t need to have any previous experience of teaching.

Many people for whom English is a first language or those who have acquired English informally feel that their grammatical knowledge is poor: “I speak the language but I can’t explain why. How can I teach it?” is a common concern.

We are unique in offering a pre-CertTESOL Language Awareness course to help prepare you, should you feel you need it, in addition to the required 20 hour pre-course task. This course is available on payment of the 400€ deposit and we strongly recommend that all trainees complete it before starting the course. It will take you through the basics of English grammar and phonology and help to prepare you for the exam you will take to assess Unit 2: Language Awareness. You will also learn more about language and grammar as you move through the CertTESOL course.

First, complete our application form. We will check your application and get in touch to organise your interview which will take place on Zoom.

During the online interview, we will ask you about your motivations for doing the course, your teaching and learning experience, your plans after the course and your expectations of the course. We will also complete a short language awareness exercise. Our aim is to make sure that the course is the right course for you to do. If accepted, you will receive a full place offer and information about how to secure your place on the course via email.

After paying your deposit, you’ll be given access to our unique Language Awareness course, which we strongly recommend all trainees complete before starting the CertTESOL course. You will also be sent access to our online pre-course task. This is based on the required reading of the course, Trinity CertTESOL Companion (J, Anderson, DELTA Teacher Education and Preparation 2017). This book will give you a comprehensive background to the five assessed units of the course.
