Internship cover letter: prove you can learn the job fast.
Internship employers know you are still studying. What they want from the letter is evidence that you will be useful within weeks: a skill you already use, a project that looks like their work, and a clear reason you chose them.
An internship cover letter names the internship and your programme, shows one or two pieces of evidence that you can already do part of the work (a class project, a club role, a part-time job), and explains why this organisation's work interests you. End with your availability dates. One page, three or four short paragraphs, addressed to a named person when the posting gives one.
How to write it
- Name the internship and your programme. Position title, term (summer, fall, co-op) and your degree and year in the first two sentences.
- Pick the two duties that matter most. Read the posting and underline what the intern will actually do: research, data entry, social media, lab support.
- Match each duty with evidence. A project, assignment, club role or job where you did something similar, with what you produced.
- Say why this organisation. One specific detail: a product, a programme, a team or a cause, not a compliment.
- Give your dates and hours. Start and end dates, and whether you need academic credit.
- Close and sign. Ask for a conversation and sign with your full name.

| Version | Example |
|---|---|
| Weak | I am a motivated student looking for an internship to gain experience and develop my skills. |
