Deadlines Numerus fixus (selection) courses 15 January 2026, 23:59 CET · Non-EU/EEA students (visa needed) 1 April · EU/EEA students, general programmes 1 May · Studielink opens 1 October Admit rate Leiden does not publish an official undergraduate acceptance rate. Third-party sources estimate roughly 30%, but this is not an official figure and selectivity varies sharply by programme: numerus fixus courses with capped places are much harder to enter than open-enrolment courses. Always treat aggregator numbers as rough context, not a guarantee. Prompts verified from Leiden’s official requirements ↗
Leiden does not use the US Common App or the UK's UCAS. You apply through Studielink, the Netherlands' national registration system, and then complete a programme application in Leiden's portal (uSis). Studielink opens on 1 October for the following year. For most courses, admission turns on whether your diploma and grades meet the bar, not on a personal essay, so the writing you do matters less than your transcript and more than you might expect in the few places it appears.
Where writing does count, it is usually a letter of motivation rather than a US-style life-story essay. International applicants with a non-Dutch diploma often submit a motivation letter and CV as part of the uSis application, and several selective programmes ask for one directly. The challenge for Americans is to drop the personal-narrative reflex: Leiden wants a focused, evidence-based account of why this specific programme fits you, not a story about who you became on a hard day.
Leiden rewards letters that show you have read the actual curriculum. Name the course, name modules or research themes, and explain why they match what you want to study. Generic admiration for the city or the 1575 founding date does nothing.
This is closer to a UK or European motivation letter than a Common App essay. Concrete proof of interest (a book, a project, a relevant subject you went deep on) beats a moving anecdote with no academic substance.
Dutch academic culture prizes direct, well-organised writing. A clean letter with a clear claim, supporting evidence, and a logical close reads as competence. Flowery openings and vague ambition read as filler.
Admissions and selection readers want to see you understand what the degree involves, including the parts that are hard. Showing you know what you are signing up for signals you will finish.
The single most useful move is to treat the motivation letter as an argument, not a confession. Open with a specific claim about why this programme suits you, then spend the body proving it with evidence: a relevant subject you pushed past the syllabus on, a book or paper that shaped your thinking, a project that tested the field in practice. Tie each piece back to a named feature of the Leiden course. Around 80% of a strong letter is about the subject and the programme, not about you as a person in the abstract.
Check whether your programme is numerus fixus before you over-invest in prose. Courses like Psychology and International Relations and Organisations select mainly on grade average plus an online assessment plus a draw, with a hard 15 January deadline, and may not weight a motivation letter at all. If your course selects that way, put your energy into the assessment and your transcript. If your course or your route through uSis does ask for a letter, that is where this guide pays off.
Write a letter of motivation explaining why you want to study this specific Leiden bachelor's programme, what relevant background and skills you bring, and why you are a good fit.
Leiden wants a focused, evidence-based case for why this exact programme fits you academically and practically, written in clear, direct prose. It is closer to a European motivation letter than a US personal essay.
For applicants with a non-Dutch diploma, and for several selective programmes, the letter is where you show you understand what the degree involves and have genuine, demonstrable interest. It helps readers judge fit and the likelihood you will succeed and finish.
Pull up the course page and list two or three specific modules, tracks, or research themes that genuinely interest you, then write the letter toward those named features.
Identify the single strongest piece of proof for your interest (a book, a project, a subject you took beyond the syllabus) and build the letter around it rather than around your feelings.
Write down what you want to do after the degree, then show why this exact programme is the logical route there. This frames your motivation as considered rather than vague.
“Ever since I was a child, I have been passionate about understanding the world and helping people, which is why Leiden University is my dream.”
“Leiden's International Relations and Organisations track on global governance is the reason I am applying: I want to study how institutions like the UN actually constrain state behaviour, not just whether they should.”
- 1Names the exact programme and a specific theme in the first line. No throat-clearing, no childhood, straight to a focused claim.
- 2Concrete, original evidence of interest that shows the applicant went past the syllabus and drew a specific intellectual conclusion. This is the academic substance Leiden rewards.
- 3Ties the personal evidence back to named features of the Leiden curriculum, proving genuine research into this course.
- 4Addresses the international and American angle and fit briefly and practically, without making the letter about personal identity.
- Which two or three specific modules, tracks, or research themes on this programme page genuinely excite me, and why?
- What is the single strongest concrete piece of evidence that I am interested in this subject beyond just liking it?
- What do I want to do after this degree, and how does this exact programme get me there better than alternatives?
- Have I named the specific programme and at least two of its actual features, not just the university?
- Is at least 80% of the letter about the subject and the course rather than my personal story?
- Did I cut every generic line about the city, the rankings, or being passionate since childhood?
Mistakes that sink Leiden essays
A Common App-style narrative about a setback and personal growth is the wrong genre here. Leiden's letter of motivation is an academic and practical case for fit. Lead with your interest in the field, not a scene from your life.
Saying you love the Netherlands, the rankings, or the international atmosphere wastes the letter. Reference specific modules, tracks, or research strengths from the programme page so it is obvious you researched this course and no other.
Many numerus fixus programmes select on grades, an online assessment, and a draw, with no essay weighting. Confirm your programme's actual selection criteria before pouring hours into prose that may not be read.
Selection courses close in Studielink on 15 January, far earlier than the 1 April (non-EU) and 1 May (EU) general deadlines. Missing it means no place that year, regardless of how strong your letter is.
Leiden essay FAQ
Does Leiden University require an essay or personal statement?
Not in the US sense. There is no Common App essay. Many courses admit on diploma and grades alone. Where writing is required, it is usually a letter of motivation, asked for in your uSis application (common for applicants with a non-Dutch diploma) or by certain selective programmes.
What is the Leiden letter of motivation and how long should it be?
It is a focused, evidence-based explanation of why you want to study a specific programme and why you fit it. There is no single university-wide word limit, but about one page (roughly 400-600 words) is a sensible target. Always check your programme page for specific guidance.
Do Americans apply to Leiden through UCAS or the Common App?
No. Leiden uses Studielink, the Netherlands' national registration system, followed by a programme application in Leiden's uSis portal. UCAS is for UK universities and the Common App is for US universities; neither is used here.
What are the Leiden application deadlines for 2026 entry?
Numerus fixus (selection) courses close in Studielink on 15 January. For general programmes, the deadline is 1 April for non-EU/EEA students who need a visa and 1 May for EU/EEA students. Studielink opens on 1 October. Individual programmes can differ, so confirm on the course page.
Do Leiden's competitive courses select on a motivation letter?
Often not directly. Several numerus fixus programmes, including Psychology and International Relations and Organisations, select mainly on grade average plus an online assessment plus a draw. Confirm your programme's actual selection criteria before assuming the letter is weighted.
Is there an interview or admissions test for Leiden bachelor's programmes?
Interviews are not a standard part of bachelor's admission. Some numerus fixus programmes use an online assessment (multiple-choice questions with study materials provided beforehand) as part of selection, but this is course-specific, not university-wide.
