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 Delft and Rotterdam

Leiden University, Delft University of Technology and Erasmus University Rotterdam collaborate closely on a range of educational matters, including minors. All three universities reserve a third of their minor places for each other's 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'.
