According to Polish regulations any scientific degree obtained abroad has to be validated in the country in which it was issued and then presented to a Polish higher education institution in order to be recognized (nostrified).
Bodies which can nostrify academic degrees are the councils of faculties which are entitled to award the degree of habilitated doctor (doktor habilitowany).
Different rules of recognition apply to the academic degrees issued in the countries which have signed bilateral agreements on the recognition of educational credentials with Poland. The information on bilateral agreements is available on the website ( Legal frames) of Bureau for Academic Recognition and International Exchange.
