The blended course allows you to plan your study around your teaching work – you can even complete the Teaching Practice in your own school, with your own students, or to online classes using Zoom.

Trinity DipTESOL: are you ready? Get a teacher trainer's perspective.
Our graduates are experienced professionals, here’s what some of them had to say.
“The EFA staff were lovely. With their guidance and input, my course mates and I were able to better refine our lesson plans, which helped make the lessons more engaging and enriching for our learners. I thoroughly recommend English for Asia to English teachers seeking their Cert/DipTESOL qualifications."
"The first thing I noticed about the EfA tutors I had for my DipTESOL was that they were extremely knowledgeable and gave insightful, detailed advice about how I could improve my lessons during my practical block. I couldn’t have asked for a better team to aid me in my progress to become a teacher with a deeper awareness of the subject!"
“From providing constructive feedback on my teaching practice to arranging classes for observations, the DipTESOL team at English for Asia has been very supportive. I really appreciate how the trainers were always available to discuss questions that I may have about teaching during the practical block.”
The Trinity DipTESOL comprises four components that cover the theory and practice of English Language Teaching. Our experienced tutors will help you to deepen your theoretical knowledge of teaching and learning. You will master new approaches to teaching and have the opportunity to put them into practice as the course progresses.
You will be examined according to the four units below. Some components are assessed by Trinity's panel of examiners; others are assessed by our trainers and moderated by Trinity. Attendance to a four-week block is mandatory in order to complete unit 3 and unit 4 assessments.

Units 2, 3 and 4 are usually taken together in the first instance and you have up to three years to complete any failed units or parts of units.
The syllabus places a strong emphasis on the application of theory in the classroom and also on teachers reflecting on and evaluating their own practice.
For the online phase we use a virtual classroom to provide an interactive, supportive environment where all the course content is stored in one place.
You will be in small groups, maximum 16 participants to ensure ample tutor support. Using the latest technology you will be able to see and hear your colleagues from all over the world, as well as participate in forum discussions on weekly modules throughout the course. The interaction for the latter is not scheduled so you can log into the course to suit your own working day.
The online phase is divided into three- or four-week units with rest weeks in between. The modules help prepare you for the different assessment areas.
|Teaching and Learning 1||Teaching and Learning 2||English in the World||Phonology||Grammar|
You will have the option to complete your Teaching Practice:
A 3-HOUR WRITTEN EXAM, CONSISTING OF A GRAMMAR SECTION AND TWO FURTHER SECTIONS WITH ESSAY QUESTIONS ABOUT TEACHING AND LEARNING.
The exam can be taken on any of three dates annually, in May, August and November. To help you prepare, the modules in the online phase will cover a wide range of areas on teaching and learning and we include grammar and essay practice throughout the course with detailed written and verbal feedback from tutors, as well as two mock exams. There are four grammar modules on the course.
A PORTFOLIO OF 3 ACTION RESEARCH PROJECTS.
These involve observing other teachers, reflecting on your own teaching and a research project on an area of ELT that interests you.
To help you prepare, you will be given group and individual guidance and support from our online course director with regular Skype tutorials and plenty of guidance and feedback on how to plan and carry out the projects. There is a module dedicated to part two in the online phase to establish expectations and learn more about action research.
AN ORAL INTERVIEW ABOUT PHONOLOGY CONDUCTED BY A TRINITY EXAMINER.
To help you prepare we dedicate three modules to phonology and provide ongoing support, testing and practice. We also include further phonology workshops and mock interviews during the face to face part of the course.
CLASSROOM DEMONSTRATION OF YOUR TEACHING.
You will be assessed by our tutors on four 60 minute lessons, and then there is a further external assessed lesson observed by a Trinity examiner. You will also present a portfolio of documentation related to the four internally assessed lessons, which includes your plans, materials and profiles of the learners.
To help you prepare we make the course practical in nature giving lots of opportunities to try things out in class and reflect on outcomes with your colleagues and tutors throughout the online phase. You will be asked to create lesson plans, discuss lessons and record teaching diaries. You will have guidance, observation and feedback on your teaching from tutors before the formally assessed lessons.
Parts three and four are usually taken together and we aim to prepare you to do these parts in the face-to-face block. Part two is usually submitted at the same time but can be submitted separately.

There are only two international diplomas recognised by the British Council and by employers worldwide: the Trinity Diploma in TESOL and the DELTA offered by Cambridge ESOL.
Although similar in its content and level of demand, the two courses differ in terms of more specific components and types of moderation and assessment. For example, both courses have an exam and assess teaching practice, but the DipTESOL has an explicit unit on integrating phonology into teaching and also allows more flexibility with the research element of the course.
