Quality and integrity

Leiden University stands for high quality research. Integrity and reliability in the way we conduct research are core beliefs in Leiden.

The research at Leiden University must be beyond doubt. We therefore expect our scientists to adhere to the codes that apply to ethical scientific practice. It is important that it is clear to everyone whether, and if so, which positions our academic staff hold in addition to their appointment as a researcher at Leiden University.

The quality of our research can be seen, among other things, from the results of the evaluations external committees carry out at our research institutes. Rankings also provide a picture of the quality of our research.

Responsible science also means that animal testing, which unfortunately is unavoidable in certain cases, is carried out in the most careful and humane way possible. We therefore fully comply with the rules and want to communicate clearly about this subject.
