The DipTESOL is an advanced qualification for experienced teachers, allowing career progression to senior teaching, management and teacher training roles.

What is the DipTESOL?

The DipTESOL is an internationally respected and recognised qualification for experienced teachers in ESOL/EFL. The qualification is accepted as a full TEFL qualification by the British Council, so it can be used in any British Council school in the UK or abroad.

The DipTESOL is accredited by the Qualifications and Curriculum Authority at level 7 of the Qualifications and Credit Framework (QCF), which is equivalent in difficulty to a Master’s Degree in a similar subject field.

Q |: Who is the qualification suitable for?
A |: The Dip is suitable for teachers who have been teaching in the industry for a number of years. Teaching experience is essential, as the course aims to build on existing knowledge and places significant
demands on the trainees time and workloads.
Q |: What is my earning potential?
A |: You could expect to earn a minimum of around £16 per hour in the UK. Schools that offer English classes for professionals can pay up to £30 per hour and teachers who progress to academic management may expect to earn in the region of £30,000 per year.
Q |: DipTESOL Vs DELTA: What’s the difference?
A |: The DipTESOL is acredited by Trinity College London.  The DELTA is acredited by Cambridge ESOL.  Essentially there is not much difference between the two qualifications.

They share similar content and provide the same level of qualification.  There are a few differences in terms of specific components and moderation, but these are the two leading qualifications in the industry and both will allow you to work in a British Council school in the UK or abroad.

Teach English Abroad
The DipTESOL is a part-time course, designed to work around your employment.  The DipTESOL has a minimum of 150 timetabled hours, plus another 450 hours of self-study.  It is designed around four different units.

Unit Title Unit Description
Unit 1 Language, Teaching and Learning (the written paper) Essays focus on theoretical and practical integration using current ELT thinking. Candidates will be able to use their continuing professional development and background reading to contribute to this unit.
Unit 2 The Teacher as a Developmental, Reflective Practitioner (the portfolio) Trainees will have the opportunity to observe teachers in their workplace. The portfolio consists of three assignments. Two assignments are based around aspects of classroom practice. The third assignment is in the form of an independent research project. The candidate can choose their area of interest within TESOL to base their research, which will assist in their own professional development for their future career.
Unit 3 Phonological Theory in Classroom Practice (the interview) The interview lasts for 30 minutes and will cover phomological aspects of teaching and learning. The interview is an opportunity for the candidate to address the issues of speaking and listening skills in class and how an awareness of phonology can enhance or impede teaching and learning in these two skill areas.
Unit 4 Teaching to include Learner Analysis, Preparation, Delivery, and Self-Evaluation (teaching practice) Candidates are required to complete a minimum of four lessons, each lasting 60 minutes, all of which will be internally observed and assessed using Trinity criteria. These will cover the candidate’s pedagogic, communicative, reflective and analytical skills.
Candidates are given the opportunity to explore specific aspects of English language teaching, i.e:

  • English for Special Purposes (ESP)
  • English for young learners
  • Business English
  • ICT in the classroom
  • Lifelong learning or bilingual learning

The course takes place twice a week in the evenings and on one Saturday per month. Take a look below to see how your weeks might look (please note the tables below are for illustrative purposes only and may be subject to change).
