Most Bachelor’s programmes at Leiden University have a major-minor structure, with 15 to 30 study credits (EC) reserved for elective credits. One way to earn elective credits is by doing a minor. You can register for a minor via eduXchange.

New registration method for minors

From 2023 onwards, you will no longer register for minors via uSis. Instead, you will use eduXchange. In March 2023 you will find a film on this page demonstrating how to use eduXchange.

What is a minor?

A minor is a cohesive, carefully-compiled set of courses with introductory courses followed by more in-depth study, 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.

The best time to do a minor is in the third year of your Bachelor’s programme. 

Minors in Leiden

Leiden University offers around 50 minors:

•    Leiden University minors

Minors at TU Delft and Erasmus University Rotterdam

Leiden University, Delft University of Technology and Erasmus University Rotterdam collaborate closely on a range of educational matters, thus making it easy to follow a minor at TU Delft or the Erasmus University. During the application period for Leiden students, in April and May, TU Delft and the Erasmus University reserve a third of their minor places for Leiden University students. Just like studying abroad and internships, following a minor elsewhere can enrich your studies, your student life and your CV.

Multidisciplinary minors Leiden-Delft-Erasmus Universities

Leiden, Delft and Rotterdam also offer multidisciplinary 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.

  • You must be registered as a bachelor's student at Leiden University.
  • Your minor may not overlap with your regular studies. Are you unsure? In your study programme's Course and Examination Regulations (OER) you can read which minors you are not allowed to follow due to overlap. Don't see your minor but still not sure? Ask your board of examiners about the overlap between your minor and your programme(s) to be sure. 
  • If you only want to follow part of a minor, you need permission from the Board of Examiners
  • For some minors there are additional admission requirements, such as a specific study programme or a selection procedure. See the Prospectus for the requirements for Leiden minors. For Delft and Rotterdam minors see the websites of TU Delft and the Erasmus University. You can find an overview of the programme requirements for minors in Delft and Rotterdam in the admission matrix for TU Delft (pdf) and the admission matrix for Erasmus (pdf)

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.

* A minor with admission requirements is a minor with a different selection procedure. You can check which minors have admission requirements in the Prospectus or on the website of TU Delft and Erasmus.


  • Every minor has a limited number of places. These are allocated on a first come, first served basis (with the exception of TU Delft and Erasmus minors with admission requirements*). So apply on time.
  • You may only apply for one minor with admission requirements. 
  • You may only apply for one TUD/EUR/LDE minor.
  • If you are placed on a waiting list, you may apply for another Leiden minor (without admission requirements). Please note: you can only follow one minor. Are you placed on two waiting lists? Deregister from one of the two minors and apply for a different one. 
  • You can change or cancel your applications right up to the end of the application period. Be sure to deregister from any minor that you do not plan to follow. This way you won't block a spot that your fellow students could be using. 

Steps to take

Important: are you doing a bachelor's in Clinical Technology or Life Science & Technology? If so, select TU Delft as your current place of study in EduXchange.

If you would like to deepen your knowledge and skills in a certain area, you can choose to do a minor or electives. A minor is a predefined set of courses worth 15 or 30 ECTS. An elective is a single course of another bachelor’s programme open to external students. You can choose your minor or electives from FGGA, another faculty of Leiden University, or another university in the Netherlands.

Can I choose any minor I want?

You are allowed to choose almost all minors and electives at Leiden University, Erasmus University and Delft University and all official electives courses at Leiden University. The Minor Security, Safety and Justice is not available for Security Studies students.

Are you interested in the minor Global Affairs? You are not allowed to take part in the courses Terrorism and Counterterrorism and Humanitarian Intervention and Peacebuilding since the content is similar, fully or in part, to compulsory components of the BaSS programme. Even without these courses it remains possible to obtain 30 EC's within the minor Global Affairs.

In case you would like to do a minor or elective at another University in the Netherlands, you will need approval from the Board of Examiners.


Students are required to obtain all 60 ECTS in year one by the time of application. There must be no overlap with the BSc Security Studies content and only academic courses are allowed. This implies that courses offered by a university of applied sciences are not allowed. Additional requirements set by the minor or elective might apply.

The Board of Examiners has set the following additional requirements:

  • In principle, students are allowed to take part in all academic level electives and minors they desire, unless they overlap with BSc Security Studies content.
  • The ECTS for the minor and/or electives should in principle be obtained during the enrolment in the BSc Security Studies programme. This implies the following:
    • Students may not use ECTS obtained prior to their enrolment in the BSc Security Studies.
    • Students who are simultaneously enrolled in a second bachelor’s programme may use ECTS obtained in their second programme.
    • Students who have completed an academic level bachelor’s programme (180 ECTS) may be exempted from the elective space.
