The research specialisation is a 120 EC programme consisting of advanced courses and a substantial research project. The research project (minimum 40 EC) takes place in the second year; you may also choose up to 20 EC of electives from any field. The remainder of the 120 EC is completed with advanced mathematics courses. The programme offers considerable flexibility to tailor your track to your interests.

Find out more about the Research-oriented specialisations:

• Algebra, Geometry and Number Theory 
• Applied Mathematics

With the Education, Science Communication or Business Studies specialisations, 30–60 EC of your programme is devoted to modules in that field. This means your research track is smaller, consisting of compulsory mathematics components (54 EC) and electives (6–36 EC). Within the compulsory part you complete a 30 EC research training project and four core MSc mathematics courses (24 EC).

The High-Tech Innovation (HTI) specialisation combines mathematics with innovation-focused training. The curriculum includes 40 EC of mathematics courses (including courses from the national Mastermath programme) and a 20 EC mathematics research project. In addition, you take a 3 EC orientation course in High-Tech Innovation, 27 EC of HTI core electives, and complete a 30 EC research project within the high-tech innovation industry.

Leiden University reserves a limited number of rooms each year for international students. However, as the number of housing requests always greatly exceeds the number of rooms available, we strongly recommend that you also look into other housing options at the same time. Read more about how and when to arrange housing. If you want to request accommodation via Leiden University, submit both your application for admission and your housing request well before the deadlines! Accommodation is offered on a first-come first-served basis and is not guaranteed. You don’t have to await admission before requesting housing.

If you want to apply for a scholarship, grant or loan, please bear in mind that different deadlines apply, and these deadlines can often be earlier. Deadlines vary per scholarship. Visit the scholarship website for more details.

You can apply for admission before receiving the results of your English language test. However, a sufficient result will then be a condition of your eventual admission. Of course, if you already have your English language test results, you can upload them directly.

• Digital copies of diplomas and transcripts are initially required. Once you have been admitted, we will inform you how to submit certified copies.
• The documents must be in the original language. If they are not in English, Dutch, German or French, they must be accompanied by official translations into one of these languages.
• If you have not yet completed your current programme, state your expected graduation date and submit copies of all transcripts obtained to date plus a list of subjects still to be completed.

Application Form Programme (‘’aanmeldformulier opleiding’’): placement letter

In the application system you will be asked to upload an ''Application Form Programme''  (‘’aanmeldformulier opleiding’’). For this programme, that means a placement letter. In this letter you are asked to explain in writing that you possess the same level of knowledge, understanding and skills as applicants who are holding a Bachelor’s degree in Mathematics (Wiskunde) from a research university in the Netherlands.

1. Go to Studielink and enter your details according to the instructions provided. For this step you will need:

• a copy of your valid passport or European ID card, or
• if you are a Dutch resident, your DigiD. 

Be aware! If you wish to apply for a specialisation of a master's programme: first select the master’s programme in Studielink, then select the specialisation for which you wish to apply in Step 4 (Institutional Questions) in Studielink.

2. Within two days you will receive:

• an email with information on the next steps you'll need to take;
• your university ULCN student account details (unless, of course, you already have a ULCN account)
• the link to Leiden University’s online application portal (uSis)

After receiving your ULCN student account details, log into Leiden University’s online application portal (uSis), using the link provided. Here you can view the status of your application, which will be one of two possibilities.

1. You can be directly admitted
If your (Dutch) diploma grants you direct admission, Leiden University's online application portal (uSis) will let you know. The portal provides an overview of what you have to do to complete your application, for example arranging housing, scholarships, applying for a visa/residence permit and insurances. Please follow the instructions carefully and proceed to step 3 Student registration.

2. You cannot be directly admitted: additional action is required
If you do not have a (Dutch) diploma that grants you direct admission, we will require additional documents to allow us to decide about your application. The online application portal (uSis) will tell you this and explain how to do so. See also Part 2: Admission to Leiden University.

In our online application portal (uSis) you can finalise your application by uploading the necessary documents and answering a few questions. This portal provides an overview of what you need to do to complete your admission application. Please follow the instructions carefully and make sure to include all the items that are asked for. We strongly recommend that you complete your application well in advance of the application deadline.

All applicants with an international degree must pay a non-refundable €100 application fee, which entitles you to apply for up to three programmes/specialisations in the same academic year. We cannot start processing your application until we receive this application fee, so please pay it as soon as possible. The online application system explains how you can pay it.

Can I be exempted from paying the application fee?
You do not have to pay the application fee if:

• You are following, or have completed, a bachelor’s degree at a Dutch university (of applied sciences). 
• You have previously registered as an exchange, bachelor’s, master’s or pre-master’s student at Leiden University.
• You have previously been admitted to the same degree programme at Leiden University, but you decided to postpone your studies. This does not apply if you are applying for a different study programme or specialisation.
• You have refugee status in the Netherlands (with a residence permit for asylum).

Exemptions cannot be granted for any other reasons.

After you have submitted your application, the online application portal (uSis) will, if applicable, ask you if you want to apply for student housing, a visa/residence permit or a scholarship. Be sure to make a careful note of the relevant deadlines for these options.  

After receiving your application fee payment (if applicable), the Admissions Office will check whether all the necessary documents have been uploaded and they will inform you by email whether any further items are required. The Board of Admissions of the faculty will then:

• decide whether you meet the admission requirements for the programme; 
• strive to issue a decision on your completed application within four to six weeks of the University receiving it.

Once a decision has been reached you will be informed by email. You can view your admission status in the online application portal (uSis).

There are three possible outcomes:

1. You are admitted
   You have met all conditions for admission.
2. You are conditionally admitted
   You will be admitted, provided that you meet certain conditions. These conditions will be specified in the online application portal (uSis).
3. You are not admitted

The reason(s) for non-admission will be clearly stated in the online application portal (uSis). If you are informed that you have been (conditionally) admitted, you will have to take a number of additional steps.

If you are (conditionally) admitted, the Admissions Office will ask you to confirm whether you will join the study programme. You can do so in the online application portal (uSis).

1.    Go to ‘Application study programme’ in the online application portal (uSis).
2.    Open the ‘Confirm’ screen. Here you will see three options:

• Yes, I want to study at Leiden University.
• No, I no longer wish to study at Leiden University and hereby withdraw my application.
• Maybe later; I do not wish to start this semester/academic year. I would like to receive further instructions by email.

The sooner the better
Confirm attendance as soon as possible, to avoid missing other important deadlines and information about your study programme.

Changing your mind
You can still change your mind if necessary, either in uSis or by contacting the Admissions Office master team.  

Deadline final decision 
Do you need a student visa or residence permit? You can only request one after confirming attendance. So make sure to confirm attendance before the visa/residence permit deadline. 

If you don’t need a visa or residence permit, the latest deadline for confirming attendance is before the start date of your study programme.

Check in the online application portal (uSis) whether you need to submit any documents to meet the conditions of your admission. Instructions on how to do so will be provided in uSis.

Arrange the payment of your tuition fee before the official start date of your programme. You will receive instructions and information on the available payment methods by email.
