ACE TEFL is a teacher development centre – a place where teachers can learn, develop and qualify. We aim to improve the quality of English Language Teaching (ELT) in Greece and abroad, by offering training and consultancy services to ELT professionals, such as teachers, trainers, teachers’ associations, schools and publishers. ACE TEFL was founded by two experienced teacher educators, Alexander Makarios and George Vassilakis, in January 2021, right in the middle of a COVID-19 lockdown in Greece,  and was granted authorisation by Cambridge to run CELTA and DELTA courses in April 2021. In addition to our Cambridge teaching qualification programmes, we offer a range of short courses for teachers and trainers, and support foreign language schools with syllabus and course design, teacher observation and evaluation, as well as in-service seminars, workshops and courses. In our first year of operation:

  • we have trained 112 teachers from nine different countries on CELTA, DELTA and Train the Trainer courses.
  • we have conducted 14 online training workshops, with more than 500 teachers taking part.
  • we have participated in 6 ELT conferences with talks and workshops.

The feedback we have received so far from participants in our workshops and courses has been excellent; our rating, based on verified trainee evaluations, on the independent site is 99%.

ACE TEFL is committed to continuing to offer high quality training and consultancy services, both online and face to face. We have planned a range of full time and part time courses for teachers for 2022, including CELTA and DELTA courses.
