PhD Position Netherlands: Motivation Letter Guide

PhD Position Netherlands: Motivation Letter Guide

A PhD position in the Netherlands is employment for four years, split in both ads below into a first contract with a go/no-go assessment and an extension. The motivation letter is a job letter for one advertised project. Keep it to one page unless the ad says otherwise, and state your affiliations exactly, because at TU Delft the letter and CV feed a knowledge-security assessment.

Our existing Dutch motivation-letter guides are written for master's applications. That is a different reader. A master's committee admits you to a programme; a PhD panel hires you for a funded project and must justify the hire. If you are writing for an MSc, use the guide to Dutch master's motivation letters instead. If you already have a draft for a vacancy, choose the PhD position cover letter rubric for a free review.

Every TU Delft, University of Amsterdam and NWO page quoted below was checked on 31 October 2026. The TU Delft vacancy closes on 1 November 2026, and the UvA vacancy closed on 6 September 2025. We use both as examples of what Dutch ads ask for, not as positions to apply to.

A Dutch PhD is a job: what the ad is telling you

Two Dutch ads, two universities, the same structure.

Sources: the TU Delft vacancy and the UvA ILLC vacancy.

What this means for the letter:

• The reader is a hiring panel for a fixed project. It needs to know you can do this project, not that you love research in general.
• The go/no-go is a progress test within 15 months at TU Delft. Our reading: a panel hiring under that rule is asking whether you can produce results early. Evidence that you finished a piece of research on time is worth more than ambition.
• Teaching may be part of the job. If the ad says so, one line on teaching or tutoring you have done answers a real requirement.

What the documents and limits actually are

The ad is the contract. TU Delft says: "You can apply online. We will not process applications sent by email and/or post." The UvA ad says "all files besides your cv should be submitted in one single pdf file". An emailed letter is not processed at TU Delft, whatever it says.

On length, the UvA ad sets "Motivation letter (max 1 page)". The TU Delft ad sets no length. Our recommendation: when no length is stated, write one page. The UvA cap is one Dutch ad's rule, not a national standard, and a second page gives the panel nothing the first could not.

Where an ad asks for a research proposal, as UvA's did ("An one-page research proposal outlining a possible focus for your PhD project within the theme"), the proposal carries your research idea and the letter does not repeat it. The letter says why you, the proposal says what.

The knowledge-security check reads your letter

The rule that changes the letter is in the ad's small print. The TU Delft vacancy says:

"As part of knowledge security, TU Delft conducts a risk assessment during the recruitment of personnel. We do this, among other things, to prevent the unwanted transfer of sensitive knowledge and technology. The assessment is based on information provided by the candidates themselves, such as their motivation letter and CV, and takes place at the final stages of the selection process."

TU Delft's knowledge security page adds that the assessment "looks at the sensitivity of the research area and the candidates' affiliations from work and study." Its listed questions include: "Does the collaboration fall under EU Sanctions Regulations?", "Does the collaboration fall under export control regulations?" and "Is the institution or person (indirectly) affiliated with a military organization outside the EU or NATO?"

The UvA ad is shorter: "A knowledge security check can be part of the selection procedure". Nationally, NWO's knowledge security page describes the government's National Knowledge Security Guidelines as "country-neutral".

Our view: treat the letter as a record, not only a pitch. Three writing rules follow.

1. Name every institution by its full, official name. Do not shorten or soften a name.
2. List current affiliations once, plainly. Employer, research post, funder. If you hold none besides your university, say so.
3. Describe your past research at the level it was done. Overstating your role in a sensitive project creates a risk you did not have.

The countercase: do not write the letter defensively. The assessment runs on final candidates only, and neither page says how often it changes a decision. Accurate facts cost nothing; a paragraph defending your nationality or politics costs space the research case needs. If your university or funder may be on a sanctions or restricted list, read the guide to sanctions and PhD application letters before you write.

One page: a paragraph plan that fits

By our estimate, one A4 page at 11-point type holds about 400 to 450 words. That is four short paragraphs and one line of facts.

Cut these: the salary, the 30% ruling (the UvA ad says only that it "may apply to non-Dutch applicants"), the university's ranking, your childhood, and any list of tools without a use.

Constructed example: one-page letter for a TU Delft-style AI vacancy

Constructed example, written by us, not a real applicant statement. Context (invented): Ayesha Malik has an MS in Computer Science from a university in Lahore. She writes against the requirement lines of the TU Delft ad quoted above. The letter is 301 words, so it fits one page with room to spare.

Dear Dr. [name given in the ad],

I am applying for the PhD position in Sustainable Generative AI for Digital Sovereignty (job ID 3871). The task that matches my preparation is the first one in the ad: evaluating foundation models for use in specific domains, including healthcare.

My MS thesis compared three open-weight language models for summarising hospital discharge notes on a single 24 GB GPU. I built the evaluation set of 600 notes with two clinicians, wrote the scoring scripts, and measured quality, memory use and energy per summary. The smallest model, quantised to 4 bits, kept 91% of the largest model's quality on our metric at 38% of its energy. I submitted the thesis in July 2025, two months ahead of schedule. The thesis is attached.

The gap is inference across the computing continuum. I have run models on one machine, never split them between edge devices and a server. In my first months I would reproduce one published offloading result before designing my own.

I want this position because the project asks how organisations keep control of AI they depend on, not only how to make it faster. That question came up in my thesis: the hospital would not send notes to an external service, which is why we tested local models. Working with the consortium partners would let me test that constraint outside one hospital. I already work across disciplines: my thesis group included two clinicians and a hospital IT officer. I also taught two lab sections of an undergraduate machine learning course as a teaching assistant.

My current and past affiliations are: MS student, then teaching assistant, Department of Computer Science, [full official university name], Lahore (2023 to 2025). My thesis was unfunded. I have no other employer, research post or funder.

Yours sincerely, Ayesha Malik

How each paragraph maps to the ad:

• Paragraph 1 names the job ID and the ad's first responsibility, "an in-depth evaluation of existing foundation models".
• Paragraph 2 answers "Strong analytical skills" with her own measurements, not the adjective.
• Paragraph 3 is the honest gap. It answers "Ability to work independently" with a plan.
• Paragraph 4 answers "A strong interest in interdisciplinary research, and the use of AI in inter-oranisational context" [sic] with a reason from her own work.
• Paragraph 4 also answers "Ability to work independently and collaboratively within a dynamic, multidisciplinary environment" with the people she worked with.
• Paragraph 5 is the affiliations line: facts only, with no defence and no politics.

The 91% and 38% figures are part of the invented thesis, not real results. Your own numbers must come from your own work.

Before you upload

1. Read the ad's document list and file rules. Online only? One PDF?
2. Check the length: the ad's cap, or one page if none is stated.
3. Name the vacancy and job ID in the first line.
4. Give one piece of evidence per requirement you claim, with your own role.
5. State one real gap and how you would close it.
6. Write the affiliations sentence with full official names.
7. Check every date and name against your CV and transcripts.
8. Remove salary, tax, ranking and praise.

Questions about Dutch PhD motivation letters

Once you hold an offer, what a Dutch PhD offer fixes and what you can ask for covers the CAO scale, the start date and declining.

Is a PhD motivation letter the same as an MSc motivation letter?

No. The MSc letter asks a programme to admit you. The PhD letter asks a panel to employ you on one project. For MSc letters, see the TU Delft MSc motivation letter guide.

Do I address the supervisor by name?

Yes, if the ad names one. The TU Delft ad says "You can address your application to" a named supervisor. If no name is given, address the hiring committee.

Should I mention the 30% ruling or the salary?

No. The ad already states the salary. Neither tells the panel anything about your fit.

Can I reuse the letter for two vacancies?

Reuse your evidence, not the letter. Each ad has a different project and requirement list. The PhD cover letter sample and method shows how to rebuild the letter from each ad's list. For Doctoral Network posts, check the MSCA Doctoral Network cover letter guide first, because a mobility rule applies.

Who can I ask about knowledge security?

NWO says the government's Contact Point for Knowledge Security is available "to anyone working, researching or studying in a knowledge institution". As an applicant, start with the contact person in the ad. Before you name referees, read how European PhD calls handle references.

Get a free Quick Review of your PhD cover letter against GradPilot's PhD position cover letter rubric. It checks what a Dutch vacancy committee reads first: your reason for this group and project, the evidence from your own research, and how that preparation matches the vacancy text. If the ad also asks for a proposal, use the PhD research proposal rubric; if it asks for a statement of purpose instead of a letter, use the PhD adviser-fit rubric.
