The National Technical University of Athens was evaluated as the best university in Greece. It is the only one with increasing ranking in the last 5 years! Aristotle University of Thessaloniki and National & Kapodistrian University of Athens are following.

Being the major guardian of the Greek excellence, worthy to the Greek engineers' high level and ambitions, it is an effective barrier against the Greek socio-economic crisis and the Greek brain drain.

I hope all the other Greek universities will follow its lead.
