PhD Regulations Leiden University

Target Audience
Leiden University | Faculties

The PhD Regulations are established by the Doctorate Board. The regulations set out who is eligible to be a PhD candidate, what the tasks of the supervisor and co-supervisor are and which criteria the dissertation has to meet.

2021 PhD Regulations 

The 2021 PhD Regulations became effective on 8 February 2021.

In the video above, the Doctorate Board explains the new PhD regulations and the revised guidelines for PhD trajectories.

2018 PhD Regulations 

The Leiden University PhD Regulations 2018 will then be withdrawn. As of 8 February 2021, the 2021 PhD Regulations of Leiden University will apply to all doctorates for which the manuscript has not yet been approved by the supervisor at that time. In exceptional cases, a substantiated request for dispensation can be submitted to the Doctorate Board via the Dean.

Overview of PhD Procedure 

It is important that the dean and the Graduate School of the faculty where the PhD research takes place and the beadle of the University have all the information needed for the PhD procedure. A number of appendices to the PhD Regulations are therefore available that should be submitted at the points in time described in the Overview of PhD Procedure.    


  • Appendix A Request for exemption from the educational requirements relating to admission to the PhD programme.
  • Appendix B Licensing agreement for the inclusion of the dissertation in the Leiden University Institutional Repository.
  • Appendix C Letter from the dean to the PhD candidate regarding admission to the defence of the dissertation.
  • Appendix D Cum laude regulations.
  • Appendix E Ius Promovendi for senior lecturers (UHDs)
