teachers' Resource Centre AVO-Bell Sofia

All our CELTA and DELTA courses take place at AVO branch at 64 Knyaz Alexander Dondukov Blvd. in the city centre of Sofia. The building is situated close to Sofia University, the Alexander Nevski Cathedral and the National Library. Within walking distance of the school you can find numerous cafes, restaurants and bars in which you can eat, drink, relax and meet friends. There is also a quiet park with free Wi-Fi internet access and open-air summer cafes next to the school. The school also has excellent public transport links.

AVO is not only a CELTA/DELTA centre, but is also a full-time fully functional English Language School. Every day the school runs General English classes for young learners, teenagers and adults as well as English for communication, Business English and Cambridge exam preparation classes. In 2009, AVO became a Cambridge Assesment English authorised exam centre and in November it ran the first computer-based FCE exam.


Doing a CELTA/DELTA course at AVO Language & Examination Centre will give you the opportunity to see what it is like to be an EFL teacher in a real training environment.
