How do you write a cover letter for an internship?

The short answer: three paragraphs, one page

An internship cover letter is a short letter that goes with your CV and argues why you fit one internship. The career services we read agree on the shape: an opening that names the role, a middle that proves you can do the work, and a close that asks for a conversation.

What an internship letter does differently

Prospects, the UK graduate careers service, says employers do not expect previous experience from interns, but they do expect you to show what your degree has given you, the motivation to benefit from the internship and a reason for choosing that company. So the weight moves from past jobs to coursework, projects, societies and part-time work, and to why this employer.

Three questions the letter answers

Princeton's Center for Career Development frames every cover letter as three questions: who you are and what you are applying for, what value you can add, and why this particular opportunity interests you.

Princeton also notes that not every employer asks for or reads a cover letter. Send one when the posting asks, or when the form has a field for it; skip it when the posting says not to.

In the first minute: pair three requirements with three things you did

Open the internship posting and a blank note. Princeton's job-description worksheet pairs what the posting asks for with what you have done; this is a shortened version of it.

1. Copy three requirements or duties from the posting, in its own words.
2. Beside each, write one thing you did that shows it: a module project, a society role, a shift at a part-time job, a volunteer task.
3. Beside each of those, write one detail you could prove: a result, a number, a date, a link or a person who saw it.
4. Write one fact about the employer that you found yourself, such as a named project, service or programme, and why it interests you.

The letter, paragraph by paragraph

Paragraph 1: the internship and one real reason

Prospects says the opening states the position, where it was advertised and when you are available. Georgetown suggests adding your major and year of study. Princeton warns against the fill-in-the-blank opening (I am a ___ major applying for ___) and prefers something specific, such as how a course drew you to the field, or a contact you made at an information session.

Paragraph 2: evidence from what you have actually done

Prospects' advice for a letter with no experience is to list what you have rather than what you lack: relevant modules and what they taught you, any part-time work, and societies, teams or personal projects, with the skill each shows. Its page says all experience is transferable in some way. MIT adds that you should say what you learned from an experience, not just what you did.

Georgetown suggests three or four achievements and MIT at least two body paragraphs. On one page, two or three examples fit.

Paragraph 3: availability, a request and contact details

Princeton's sample inquiry gives exact dates: when exams end and the weeks the student can work. Prospects also puts availability in the letter. End by thanking the reader, asking for an interview or a conversation, and giving your phone number and email. Princeton says the ending should restate your interest, and MIT says the conclusion should reinforce your fit and thank the reader.

Illustrative skeleton to adapt, not copy. Square brackets mark what only you can fill in. Dear [name of the internship coordinator or hiring manager]: I am applying for the [internship title] for [season and year], which I saw on [site]. [One specific reason this employer or its work interests you.] In [module or project], I [what you did], which [a result you can show]. In [society, part-time job or volunteering], I [what you did] for [scope]. Both are the kind of work your posting lists under [requirement]. I am available from [date] to [date] and would welcome a conversation about the role. You can reach me on [phone] or [email]. Thank you for your time. Yours sincerely, [your name].

Weak lines and stronger lines

The right-hand column is our own illustration of the form, not text from a source. Every bracket is a fact only you can supply, and any number you write must be one you can explain in an interview.

Princeton and Georgetown both say employers can tell a template when they see one. Prospects says to avoid copying and pasting.

Where the sources disagree, and what to do

Sending it: email, upload or form

• Email with the letter in the body: Princeton says to drop the address block and start with the greeting, and to add a clear subject line such as Candidate for [job title].
• Upload: Prospects says to save the letter as a PDF so it opens the same everywhere, in the same font and size as your CV.
• Form with no letter field: some internships use forms, interviews or assessment centres instead of a letter, Prospects says. Put the two examples closest to the posting into the free-text answers.

When no internship is advertised

Prospects says speculative applications can work: research the company first and find the right person to send it to. The National Careers Service says to tell them what sort of job you are looking for and show your enthusiasm for the organisation. Princeton publishes a sample inquiry that says plainly that no internship was posted, shares the student's background, and gives the weeks the student is free.

1. Say in the first sentence that no internship was posted and what work you want.
2. Give one reason for this organisation, from something you read.
3. Offer two examples and your exact availability.
4. Name a person in the greeting.

Applying in Turkey

Kariyer.net, the Turkish job site, says in its internship guide that adding a cover letter strengthens your hand, and that for bank internships a letter is generally expected and welcomed. The page was last updated on 11 June 2025. The Gebze Technical University bioengineering internship committee's guide shows a short Turkish internship letter that opens with the department and year, asks for a summer internship, mentions projects and clubs, states a career goal and asks for an interview.

Proof: what we read and when

We read each page below on 8 October 2026. The date column is the update date the page itself shows, or where it shows none.

A checklist before you send it

1. The internship title and the employer name are spelled as in the posting.
2. Each example answers a requirement the posting actually lists.
3. Every number and date matches something you can show.
4. It gives your availability in dates.
5. It is about 300 words, or fits on one page.
6. You read it aloud, as MIT suggests, and cut what you would not say to the interviewer.

Where CitedCV fits

CitedCV is a CV builder that writes only from the facts you give it, and it writes cover letters the same way. Letters need a credit pack, any pack, and cost 4 credits each. A free account cannot write one.

• Before any credit moves, it checks that you have at least one role on file and something you did: an achievement, a number or a project. With none, it says so and writes nothing, at no cost.
• Code, not the language model, matches the posting's requirements to your facts and plans up to four paragraphs: one on fit, up to two stories, and a motivation paragraph only when you have answered the questions about the employer.
• A requirement that nothing on file answers is left out of the letter, not claimed.
• If you have only education and coursework on file, the worksheet above is the better route, and your own sentences will be more accurate than any draft.

The guide to AI cover letters explains how each paragraph is checked against your facts and where that check stops.

Who this guide is not for

• You are applying for a research or academic placement. Those letters follow the conventions of the lab or department; ask your supervisor or career office.
• You want a letter to copy. The skeleton shows a shape; every source here asks for a letter written for one internship.
• The posting says not to send a letter, or the form has no place for one.
