In principle, external PhD students have the same rights and obligations as internal PhD students. They likewise have to submit their personnel data in Hora Finita, including a plan for doing trainings, as soon they start the PhD trajectory.
External PhD students also have to meet the 30-credit requirement as otherwise they will not be allowed to take their degree. External PhD students can also apply for exemption from education. This must be approved by the Doctorate Board of the relevant research institute.
