Our courses include the Cambridge CELTA Certificate course as well as a range of other courses, from English for English Language Teachers & Grammar for English Language Teachers preparatory programmes for TEFL teachers to the post-graduate Cambridge Delta Diploma. But apart from these two flagship courses which have built our great reputation as a centre, we also offer a variety of shorter course options as well as workshops and consultation services for language centres.

CELT trainees come from many countries (the United States, the United Kingdom, Australia, S.Africa and more) as well as from Greece. They come to CELT to start or develop their teaching careers; many currently hold posts of responsibility in Greece and overseas.
