What is the Trinity College London DipTESOL?

The Trinity College London Diploma in Teaching English to Speakers of Other Languages (DipTESOL) is an English Language Teaching qualification rated at a Level 7 on Ofqual’s Regulated Qualifications Framework which makes it comparable to a Master’s degree or any other post-graduate qualification. It is ideal for experienced practitioners wishing to progress to positions in management, teacher education and examining. It’s also suitable for teachers wanting to advance their knowledge and skills for their own personal development, or to support and guide less experienced colleagues. The Trinity College London DipTESOL is accepted by the British Council and other international teaching organisations around the world as a full English language teaching certification.

Do you have any further questions? Here are some FAQs!

About the DipTESOL

If you had to google this question, you’d perhaps get multiple sources stating that, just like the CertTESOL and the CELTA, the key difference between these courses is the awarding body – the DipTESOL is awarded by Trinity College London while the DELTA is awarded by the University of Cambridge – and all other differences are minor, leading participants of both courses to similar outcomes.

Now, this is certainly true for the Level 5 qualifications, but it’s a bit more complicated for the Level 7 qualifications. While the Trinity College London DipTESOL and the Cambridge DELTA both have an equal standing in the world of EFL teaching, the differences in the individual modules should be considered before making a decision.

The DipTESOL has 4 units – an extra unit focused mainly on integrating phonology into teaching. The research element of the DipTESOL, as well as the teaching practice sessions allow course participants more flexibility and autonomy. The DipTESOL has 3 types of research projects – allowing participants complete freedom of choice within the purview of each specific type. Teaching practice sessions in the DipTESOL include constant guidance and feedback from tutors through pre- and post- lesson discussions with facilitators.

On the other hand, with 3 modules, the DELTA does not have a phonology-focused module, and requires only a post-lesson written reflection after every teaching practice lesson, with no pre- or post- lesson discussions. The research element of the DELTA allows for only 1 of 2 types of projects – focused on either course design or teaching management.

While professionally the DipTESOL and the DELTA open similar doors, a participant’s choice should be made based on what they wish to gain from the course – what skills they want to develop and what they feel would benefit them more in the future.

You can read more in detail about the differences between the DipTESOL and the DELTA on our blog here.

You can also look at the articles on the topic by Dublin TEFL here and here, which we believe to be quite insightful.

The DipTESOL opens up positions in management, teacher education and examining – holders are eligible to apply to positions for senior teachers, academic managers, course directors, CertTESOL tutors, etc.

For native speakers of English, the possibilities are endless; the opportunities for non-native speakers are slightly more limited, as some employers prefer hiring native speakers in such roles; however, countries in Asia and South America like Japan, the UAE, India, Vietnam, Thailand, Cambodia, Columbia, Nepal and Ecuador are very welcoming to non-native speaking Trinity College London DipTESOL holders.

It is important to be realistic about the fact that the passport you hold may open or close certain doors for you; however, if you’re open to adventures and taking chances, there is a plethora of opportunities waiting for you, both online and offline.

You are required to hold a degree or equivalent qualification, an initial teaching qualification and have a minimum English language proficiency of CEFR level C1 or above to take the course. However, you may be considered eligible if you have enough professional experience to stand in for the lack of a degree.

An initial TEFL qualification such as the Trinity College London CertTESOL or the Cambridge CELTA is highly desirable but not essential.

The total minimum amount of ESOL teaching experience required is 960 hours (this amounts to approximately 2 years of full-time teaching experience), whether this has been completed full-time or part-time. A minimum of 75% of claimed teaching experience must be with classes while 25% may have been with one-to-one learners. All claimed ESOL teaching experience must have occurred within the five years prior to the interview for the course and the candidate must have had no more than one year’s break from ESOL teaching immediately prior to the start of the course. The teaching of all subjects other than ESOL is normally excluded from claimable teaching experience.

We advise our participants to completely commit themselves to the journey – it is an intensive course and needs your 100%. We recommend that you have no other academic or professional commitments during the time that you choose to take up the course so that you can get the most out of the experience. It is an enriching learning experience and you can have a lot of fun on the way, but you also have to be prepared for the longest roller coaster of your life! Don’t worry though, we have very supportive tutors who will guide you every step of the way. As long as you come with an open mind and no other distractions, you’ll be good to go.

CILA has multiple desktop computers with active internet connections that can be used to complete your assignments, should you need to; however, these will only be available from 9 am to 5 pm and are for the perusal of the staff and students alike – as such, we cannot promise that these will always be available to participants for use as per their convenience.

Right at CILA! You can print up to 500 sheets for free. However, there are several print shops at a stone’s throw from the main gate of INKEL Business Park that are open from Monday to Saturday – you can also visit these if you need anything printed after working hours.

Initially, I was sceptical about opting the course in CILA but I must confess being a learner there is one of the best decisions of my professional life. Starting from tutors to management to services to infrastructure everything was at par my expectations. I have experienced a noticeable difference in my performance and I highly recommend CILA to everyone who wishes to perform well in his career or in various examinations related to English language.

I truly had a fabulous experience at this course! The entire course is brilliantly designed. The faculty John Duthie and Mayank are amazing and we have indeed learnt a lot from them. They have not left any stone unturned in providing us the best of everything. Sufficient material, practical application made this entire journey a value add! A must for all the English teachers who want to deliver their best!

Dipti Kenia

CILA is one of the best language institutes that I have come across in Kerala. They have partnership with Trinity College London and they do a wonderful job with CertTESOL and Diploma in TESOL. All the teachers are well experienced. I am happy to do my CertTESOL from CILA and it was an incredible journey from the beginning to the end. I would recommend any who are interested in joining their team as a trainer or join the TESOL programs

It was an insightful journey at CILA, completing TESOL certification, the only authentic TESOL certification course in India. Kudos to the team that brought the best in me.

Sowmya Varadharajan

Nice atmosphere. Efficient Management. I did my TESOL here at CILA and had fun the entire time I spent here. You might want to come here and be part of a worthwhile experience with the tutors and students!

Jerome Vadackel

I swear by CILA for the Trinity Tesol course. It was a transformational experience for me. My peers in my batch and I learnt and practised many new teaching-learning strategies during the course. A combination of acquisition of new skills and unlearning outdated practices happened at every stage of the course. My tutors, Mr. John Duthie, Mr. Mayank and Mr. Jaimon were quite warm and extremely supportive throughout the course. Their mentoring was highly effective. If you want to become a learner-centric English teacher who is ready to work hard, get updated and is open to critical feedback, then TESOL at CILA is the right choice.
