Our DipTESOL tutors

Who is this course for?

The Trinity Diploma in TESOL is for English Language teachers (including primary and secondary school teachers) who have at least two years of full-time teaching experience of a variety of English language levels. Ideally, you would also have an initial qualification in ELT such as the Trinity CertTESOL as well. We won’t accept teachers onto the course unless we believe that you have the necessary experience and a strong chance of passing the course.

How can I take this course?

7 months online + 4 weeks face to face at CILA, Cochin, Kerala

The online phase

You would complete seven months of online training (350 hours in total) in our virtual classroom with a group of up to 16 international fellow teachers and our team of expert tutors. You will participate in forums, webinars, live video classes and email exchanges as you progress through the course. There are twenty, week-long modules (with some rest weeks in between) lead by one of our tutors. The interaction is not scheduled (other than a 45-minute live video class), so you can log into the course throughout the week to suit your own working day to complete your weekly assignments and prepare for exams.

How will I be assessed?

There are four assessed units on The Trinity DipTESOL course.

o    Unit 2 – A coursework portfolio including three action research projects. The projects involve observation of other trained teachers, reflection on your own teaching and a research project where you collect data. The expertise of your tutor will be matched to your chosen field. Work on the portfolio will be completed throughout the course You will need to base the reflection task on teaching a group or groups of at least 6 students for 15 hours in total.

Four lessons are assessed by Oxford Tefl tutors, the fifth by a Trinity examiner. For this part of the exam, you will be teaching students in one of our centres.
