How to Write a UN Cover Letter (With Examples)

A UN cover letter is not a personal statement. It is scored — and on several UN application systems it is not a separate letter at all but a field inside the form: the motivation statement. Get its structure right and you clear the first screen; treat it as an essay and the screening happens without you.

The rules differ by organization. The UN Secretariat requires a motivation statement, UNDP, UNICEF and WFP ask for a cover letter alongside a CV, and WHO makes one optional. Here is what each expects, what belongs in every part, and two labelled models you can adapt.

Why Is a UN Cover Letter Different From a Private-Sector One?

A private-sector letter sells a story. A UN letter answers a specification. Secretariat vacancy notices carry a Competencies section naming what the panel will assess, and UNDP tells applicants that the competencies listed for the position are assessed during selection. Inspira screens the form first, against rules on age, qualifications, length of experience, family relationships and criminal record. Your letter works on the humans — but only after the form has cleared the machine.

The vocabulary those panels share is the Secretariat’s Values and Behaviours Framework: four values — Inclusion, Integrity, Humility and Humanity — and five behaviours, including Analyse and Plan and Deliver Results with Positive Impact — and it informs recruitment.

Which Organizations Ask for a Motivation Statement — and Which Ask for a Letter?

• UN Secretariat (Inspira): a mandatory motivation statement of three to four paragraphs, customised for each job opening. The application itself is an extended online resume covering education, competencies, achievements and experience — the statement adds what the form cannot say.
• UNDP: the online application form plus a CV and a cover letter, which is a section of the application; UNDP advises a separate, relevant letter for each position.
• UNICEF: for most applications, an online recruitment profile, a CV and a cover letter of normally no more than 1 page, with a two- to three-paragraph overview of why you are suitable.
• WFP: its notices state that at the application stage the only required documents are your CV and cover letter.
• WHO: the Stellis application has an optional cover letter step, where you type or paste text specific to the vacancy.

What Goes in Each Part of the Letter?

• The opening — two or three sentences. Name the job opening: title, number, duty station, then the two or three requirements you most directly meet. Do not open with your career history.
• The competency paragraphs — the core. Take the competencies the notice names and give each one a short paragraph with a real example and a result.
• Motivation — why this organization and this duty station. Name the mandate or the country context and connect it to something you have done. A sentence that would fit any vacancy fits none.
• The closing — restate your fit, confirm your availability or notice period, and sign off, with no new claims.

Length is set by the system: three to four paragraphs in Inspira, a page at most for UNICEF.

What Do Strong Paragraphs Actually Look Like?

Both extracts are illustrative models we have written — not the words of any real applicant, and not UN templates. The brackets mark where your own detail goes.

Example 1: An Opening Paragraph

I am applying for the Programme Officer post advertised as job opening [number] at [duty station]. The notice asks for experience coordinating multi-stakeholder programmes in a post-conflict setting and for the ability to deliver results with positive impact. That is the work I have done for five years in [country]: chairing a monthly partner forum across four implementing agencies, and rebuilding a reporting cycle that had fallen behind schedule.

Example 2: A Competency Paragraph

Analyse and plan: when I inherited a four-province portfolio whose workplan had no delivery milestones, I mapped every output against the donor agreement, agreed a quarterly milestone schedule with each implementing partner, and reduced late reports from two a year to none. When one partner slipped in the third quarter, the schedule flagged it in week two rather than week ten, and I reallocated the budget line before the deadline.

Which Mistakes Sink Applications?

• Restating the CV. Inspira asks you to use the motivation statement for details not already in your application.
• Addressing the wrong competencies. A pasted letter answering a different notice is visible immediately — the panel scores what this notice names.
• Generic motivation. “I have always wanted to work for the United Nations” says nothing about the entity, the mandate or the duty station.
• The wrong length. A two-page narrative pasted into a three-paragraph field is a formatting failure before it is a writing failure.
• Treating submission as reversible. Once a Secretariat application is submitted you cannot change it, and you cannot apply to that opening again.

---

What Should You Check Before You Submit?

• Does the first paragraph name the job opening, the duty station and two requirements?
• Is every competency the notice names present, with evidence attached?
• Is there a sentence naming this organization and duty station that could not be pasted elsewhere?
• Is the length what the system asks for?
• Have you cut every line that repeats the form, and read the rest aloud once?

A cover letter will not rescue an application that fails the eligibility screen, but it decides what happens to the ones that pass. Write it against the notice, not your career, and draft it before the vacancy you want is published. You can browse every open vacancy and filter by agency, grade or duty station to find the notices worth writing for.
