Trinity CertTESOL Entry Requirements

To successfully apply and participate you must be at least 18 years old and have:

    • The capability to cope with the academic requirements of the course. This may mean having a university degree, or the academic qualifications that would have enabled you to get accepted on to a degree course.
      • Please be ready to provide us with a copy of your most significant academic certificate as it is a Trinity College stipulation that proof of qualifications is rigorously checked.
    • For applicants without the above, awareness of relevant transferable skills that have been acquired through work experience may instead be considered necessary.
    • The skills to fluently and accurately communicate in spoken and written English. Applicants who do not have English as their mother tongue require an IELTS score of 7.0 (or equivalent) in each of the four skills. Applicants for whom English is their mother tongue must hold a GCSE in English (grade C minimum).
    • Interest in learning and teaching & appropriate personal qualities for teaching.
    • Adequate health to deal with the demands of an intensive course of training.


It is not essential to:

  • have English as your mother tongue
  • have knowledge of a foreign language
  • have any prior teaching experience

What to expect from the course

The Trinity CertTESOL consists of several different components:

  1. Input sessions with course tutors: These sessions take place during the morning and examine the theoretical and practical aspects of EFL teaching. You will be introduced to techniques that you can apply in lessons and dedicated sessions on the study of grammar, pronunciation and other aspects of the English language.
  2. Guided Teaching Practice: You will complete six hours of supervised classroom teaching. Classes consist of a minimum of six people and are composed of multi-lingual students.
  3. Observations of Professional Teachers: You will need to observe several lessons in order to further your ability to assess a teacher’s performance.
  4. Unknown Language Training: You will spend four hours learning an unknown language during the course to help you identify the problems faced by learners and encourage you to analyse your own reactions to the learning experience and the teaching skills on display.
  5. Learner Profile: You will spend several hours interviewing, teaching and analysing the language capabilities and study style of a student on a one-to-one basis.
  6. Written assignments: You will be asked to complete a series of journals relating to the components above to help you analyse and reflect upon your learning.
  7. Assessment of Language Awareness: There is no external exam at the end of the course. However, trainees take an internal Language Awareness Test in the final week and speak with a Trinity Moderator about various aspects of the Trinity CertTESOL course.

The course will help you:

  • Become aware of a learner’s needs and motivation
  • Create and maintain learner interest
  • Prepare lessons plans with achievable aims
  • Stimulate and maintain active participation in a class
  • Develop knowledge of phonological, lexical and syntactic features of contemporary English
