Certificate Course Details

The Trinity Certificate in TESOL is for people who want an internationally recognised qualification and practical course of teacher training.

A really good course. The teachers are professional and approachable and the attendance of the moderator from Trinity gives the whole thing validity. A tough but rewarding few weeks. A credible course needs an element of stress; we have all survived and all feel as if we’ve achieved something big.

Below is an outline of the main features of our TESOL course. If you have any other questions please contact us or check our Frequently Asked Questions

Choosing a course

At Active Language, we currently offer online Trinity Certificate in TESOL courses. The course content for the 5-week full-time course and 11-week part-time course is the same so you can choose the course which best suits your timeframe. You can find information about dates and prices for both courses here.

Before the TESOL Course starts

When you enrol for one of our TESOL courses (following a successful face-to-face or telephone interview), you will be asked to buy CertTESOL Companion by Jason Anderson (DELTA Publishing). This book provides an excellent introduction to the course, and from it, you will complete some tasks which will be handed in (but not assessed). 
When you pay your deposit, you’ll be given access to our Language Awareness course, which we strongly recommend you complete before the CertTESOL starts. This gives you a solid introduction to the grammar and phonology of English, and helps you to prepare for Unit 2: Language Awareness, which is assessed through an exam during the CertTESOL course. 

The modules in this Language Awareness course cover areas of grammar and phonology and are designed to provide TESOL course trainees with a basic working knowledge of these TEFL subjects and how to teach them effectively. Some trainees find these sessions particularly rewarding (and challenging!), especially as many speakers of English as a first language have had very little previous opportunity of studying the nuts and bolts of their own language.

Teaching Practice

The practical nature of the TESOL course is emphasised from the very beginning. On the full-time TESOL course, trainees are divided into teaching practice groups on the first day and begin their teaching practice on the second day. Each group is assigned a practice class of real Spanish students and a teaching practice tutor. Teaching practice includes guidance on planning your lessons and feedback where the teaching practice tutor discusses the lesson with you and your peers. Halfway through the TESOL course the teaching practice groups change class. In this way, trainees have an opportunity to teach students whose English is at a different level.

Observations of both peers and tutors of the Active Language teaching staff provide further insights into lesson planning, staging and classroom management.

Input Sessions

We believe in learning through involvement, and trainees are expected to participate in different ways during the modular input. Each module of the TESOL course addresses specific language areas and ELT techniques. 

There are videos and recorded presentations to introduce you to the content and follow-up activities such as quizzes, discussions and tasks to consolidate your learning. During the onlne course, you’ll also have regular check-ins with your tutors to clarify any doubts.

Language Awareness

Having looked at the ins and outs of grammar and phonology during the Language Awareness course, the sessions during the CertTESOL course will focus on the practical aspect of teaching different linguistic points in the classroom. We’ll analyse how points can be presented in different ways and look at a variety of materials.

Language Awareness Exam

You will sit a written exam during the TESOL course, which will test your knowledge of grammar and phonology.

Written Assignments

During the TESOL course three assignments are given. These include a record of your experience learning the unknown language, a case study of one of your students with a diagnosis of their language difficulties and a project where you create original material to be used with your learners.

Learning an Unknown Language

You will participate in four language lessons in a language you have no prior experience of, taught completely in the language itself without recourse to English. This helps you put yourself in the position of a basic level learner of English and to experience communicative language teaching at first hand.


Your teaching practice, your three written assignments and your language awareness exam will all be graded. These can be pass, pass with merit and pass with distinction. If the quality of work does not reach a pass level, it will be referred. You must achieve at least a pass grade in all five assessed components of the TESOL course to be awarded a Trinity TESOL certificate. If an assignment or your language exam is refereed, you will be given an opportunity to resubmit the assignment before the TESOL course ends, with advice on what you need to do to achieve a pass grade.

Assessment on teaching practice is continuous and is based on both your classroom teaching and your ability to reflect effectively on your own and others’ teaching.

You will receive your grades on the Monday after the course has finished.

TESOL Certificates

You will receive two certificates. Trinity College awards a certificate to all successful candidates on completion of the TESOL course. In addition, we will award you a certificate with details of your grades, which employers sometimes ask for.

Careers Service

The Careers Service team will be on-hand during your course to help you get the best start in your ELT career.you
