Most Bachelor’s programmes at Leiden University have a major-minor structure, with 15 to 30 credits (ECs) reserved for electives. One way to earn elective credits is by doing a minor.

What is a minor?

A minor is a cohesive, carefully-compiled set of courses. Minors have a logical structure and cohesion, with introductory courses followed by an overview of the most important themes within a topic, thus allowing students who are less familiar with the topic to follow the minor. 

A minor allows you to explore subjects beyond the boundaries of your own study programme. It can offer new knowledge, insight and skills, perhaps from a completely different field of study. You can also use your minor as a way of preparing for a future Master’s programme.

You can follow a minor after you have obtained your first-year (propaedeutic) diploma. The best time to do a minor is in the third year of your Bachelor’s programme. It is important that you complete your minor within one year, as the range of minors on offer changes every year.


Minors in Leiden

Leiden University offers around 50 minors:

•    Minors at Leiden University

Minors in Delft and Rotterdam

Leiden University, Delft University of Technology and Erasmus University Rotterdam collaborate closely on a range of educational matters, including minors. During the application period for Leiden students, TU Delft and Erasmus University reserve a third of their minor places for Leiden University students. Just like a period of study abroad, following a minor elsewhere can enrich your studies, your student life and your CV.

Joint minors Leiden-Delft-Rotterdam

Leiden, Delft and Rotterdam also offer joint minors, taught by lecturers from the universities involved. Students from various fields of study have the opportunity to work together on a range of multidisciplinary topics. The joint minors offered in 2019-2020 are: ‘Responsible Innovation’, ‘Security, Safety and Justice’, ‘Geo-resources for the future', 'Frugal Innovation for Sustainable Global Development’ and 'African Dynamics'.

Admission requirements

  • You must have obtained your first-year (propaedeutic) diploma;
  • Your minor may not overlap with your regular studies;
  • For a minor of 15 credits (ECs) you need permission from the Board of Examiners;
  • Certain minors are only open to students following specific study programmes or have a selection procedure in place. Check in the admission matrix whether your study programme grants you access to (the selection for) your chosen minor.
  • For some minors there are additional admission requirements, which can be found in the minor information in the prospectus.

In terms of educational level, the best time to do a minor is in the third year of your Bachelor’s programme. This is an advisory note, rather than an admission requirement.


Limited places available

There are limited places available on minors and these are allocated on a first-come, first-served basis (with the exception of selection minors*). So make sure to apply on time! 

Also remember to cancel your place if you decide not to follow the minor. This will allow another student to take your place.

(Interdisciplinairy) Minors

A minor is a coherent package of courses from another programme. Minors include 30 ec of credit; for some minors it is possible to complete a half minor for which you earn 15ec. More than half of the 50 minors offered at Leiden University are offered in the English language.

Note: Minors in Psychology add no value if you are studying psychology and are not allowed.

Interdisciplinary minors

The Institute of Psychology participates in two multidisciplinary minors, which are open to psychology students:

  • Brain and Cognition

  • Kindermishandeling en Verwaarlozing: een levensloopperspectief (in Dutch)

Prospectus - minors

Minor with overlap

Please note! The material in course Statistics in the minor Tweedetaalverwerving significantly overlaps with the statistics courses within the psychology programme. This course can therefore not be included in the electives requirement. This means students following this minor would earn a maximum of 25 ec, instead of 30 ec.

  • Minor Tweedetaalverwerving (overlap with the course, Statistics)
