A PhD programme at Utrecht University always concludes with the writing of a thesis, or dissertation.
Once the thesis is complete, your supervisor determines whether or not it is ready for submission and defence. A committee of professors is appointed to read and approve the thesis and to question the candidate during an oral defence.
Dissertations from Dutch universities are held in high regard
The thesis will be made public (parts of it may have already been published as articles in international journals during the PhD). Dissertations from Dutch universities generally meet the highest academic standards and are therefore held in high regard.
Digital scientific archive
PhD candidates of Utrecht University are required to offer a digital version of their thesis to the university library. The thesis will then be incorporated in the Utrecht University Repository (formerly known as the Igitur Archive). This is the digital scientific archive of the university. This provision is part of the Doctoral Degree Regulations.
The Utrecht University Repository can be accessed through NARCIS, the Dutch portal for scientific information. Theses in the repository are easy to find worldwide because they have a unique and permanent URL and the more recent dissertations will also have a DOI from mid-2020.
