AVO Language & Examination Centre
Worldwide recognised intensive TEFL certificate courses - gain real-life teaching experience and develop your teaching skills.
AVO Language & Examination Centre is authorised by Cambridge University Press & Assessment. The school has 35 years’ experience in teaching English and 22 years’ experience in running Cambridge CELTA & DELTA courses. It is centrally located in Sofia, the capital city of Bulgaria.
Our courses are run by consistent team of highly-qualified and experienced trainers, providing trainees with guidance, support and encouragement throughout the course.
Trainees on our courses get plenty of one-to-one help and individual attention as we provide a low trainee/tutor ratio (maximum of 4 trainees to 1 tutor).
AVO offers a real classroom experience: trainees do their teaching practice on-site (except for the fully online course) .
