International Relations and Organisations (BSc)
Application and admission
The Leiden University Political Science bachelor’s programme enjoys a high popularity. To assure the quality of education, the number of students it admits is limited. This is known as a 'numerus fixus'. If there are more applications than this ‘numerus fixus’, a selection and placement procedure will determine which applicants will be offered a place in the programme. This means that we cannot guarantee all applicants enrollment, even if they meet all entry requirements. Furthermore, applicants must register their application by an earlier deadline (15 January) and meet several strict deadlines.

Sorry, applications for the coming academic year (starting in September 2023) are closed.
As of 1 October 2023 you can register for 2024-2025.

The procedures and deadlines mentioned below were valid for applications for the academic year 2023-2024.
In Spring 2023 we will update this section.
Numerus fixus: general
For specific programmes, universities in the Netherlands set a quota for the number of students who can be allocated a place. This quota is called numerus fixus. In practice, it means that you are not assured of a place if you apply for such a numerus fixus programme. If there are more applications than available places, a ranking list of applications will be established through a selection procedure. This ranking determines which applicants will be offered one of the available places first. If a place is not accepted within the set term, it will be offered to the next applicant on the ranking list. In other words: the higher your ranking, the greater your chance of being offered a place and the sooner you will be offered one of the available places. The placement procedure runs from 15 April to 31 August.
Numerus fixus: Leiden University
Leiden University maintains a numerus fixus for programmes that are very popular and would otherwise be oversubscribed. Limiting student numbers is one of the ways in which Leiden University guarantees its students the best possible education.
A set of rules applies to all numerus fixus programmes taught in the Netherlands and at Leiden University (deadlines, number of numerus fixus programmes you can apply for per academic year, how often you can apply for a particular numerus fixus programme, etc.). Please make sure to familiarise yourself with these general rules:

Numerus fixus: Political Science
Leiden University’s BSc programme in Political Science usually receive far more applications than it can accommodate. Therefore, a numerus fixus applies to this programme. It has been set at a total of 600 students for all the Political Science BSc programme tracks combined: the BSc Politicologie, the specialisation Internationale Politiek (both taught in Leiden, partially in Dutch) and the specialisation International Relations and Organisations (based in The Hague and fully English-taught).
Numerus fixus: selection criteria
The selection procedure for Political Science is based on three criteria:
- the average grades of your previous education/GPA (40% of the ranking score),
- a motivation letter (40% of the ranking score), and
- your score in an online assessment (20% of the ranking score).
Numerus fixus: details
You can find all you need to know about the selection and placement procedure on this website. Please make sure to familiarise yourself with the
- admission requirements (are you eligible for a place in the programme?);
- deadlines (when to submit what?);
- required documents (what does Leiden University need in order to process my application?)'; and the
- selection and placement procedure (how to plan my application and the next steps?).

- Login.
While setting up your Studielink account, please make sure to use an e-mail account that you regularly access and check.

A ranking number higher than 600 may also give you access to the programme
On 15 April, all applicants in the selection and placement procedure receive a ranking number. The 600 available places in the bachelor programme tracks Politicologie, Internationale Politiek and International Relations and Organisations are then initially offered to the participants with the top ranking numbers.
Each place that is not accepted within two weeks, is automatically offered to the next highest applicant. Also, when applicants withdraw from the selection and placement procedure, the free spot is directly offered to the next candidate on the ranking list. Places are offered (and have to be accepted) via Studielink until all available places have been accepted, which may continue until very shortly before the actual start of the programme.
In practice, this means that
- ranking numbers higher than 600 may very well give access to the programme;
- it is difficult to predict how many places will be freed up and reallocated from one applicant to another;
- you will have to assess yourself whether and how long you would like to wait for a place offer, if you haven’t received one yet
- you may have to apply for visa and residence permit before having been offered a place.
Below you can see which ranking number has been received an offer for placement. This information is updated bi-weekly. Please note: Because some applicants on the waiting withdraw their application, these figures present a somewhat distorted picture.

Placement updates:
