The skills to fluently and accurately communicate in spoken and written English. If English is not your native language, we require an IELTS score of 7.0 (or equivalent) in each of the four skills. If English is your native language, you need to have a GCSE in English (grade C minimum) or equivalent.

  • You should be interested in learning and teaching and have appropriate personal qualities for teaching.
  • If you don’t meet the specific requirements, we may need to see evidence that you have an awareness of relevant transferable skills that have been acquired through work experience


This course helped to systematise my knowledge of English grammar and phonology as well as gave me some important tips on the teaching methods and techniques. The most valuable tip was how to maintain the balance between student talking time and teacher talking time. Might sound easy, but it's not!


I now feel confident and capable to teach not only in person but in online spaces thanks to their guidance. I highly recommend the Trinity CertTESOL through the OI Digital Institute!
