They are apparently post graduate studies BUT not cycle 3 doctorates. As you note Tadj said Poland doesn't have a DBA. My concern is you are doing a year worth of work and according to the site's English translation a min of 60 page dissertation on top of the writing in the modules. What is the point of the DBA, EdD, DPhil that is not a recognized cycle 3 doctorate but a year of post graduate studies. In the US it would lead people to believe that you had a standard DBA, EdD and so on. The DSc is a lofty degree in some parts of Europe but in this case it is also a one year post graduate studies program. Perhaps that is the point?
