I am currently a PhD student in a EU country and recently I was advised to pursue a European Doctorate Programme.
I thought that, being "European", it was some kind of regulated, inter-country program with specific rules, but I cannot find any "official" documentation from any European institution. The only things I can find by searching on google are doctorate programs from various universities that claim to be "European".
I am aware that some EU students are encouraged to do 3-6 months of their PhD (or more) abroad, but I don't know if by doing this their PhD qualifies to be a European Doctorate.
So, what is a European Doctorate Program? Is there any regulation for it by a European institution? How does it relate with doctorate programs where students decide to spend some months abroad?
