An internship recommendation letter is a short, specific endorsement that explains why a student or early-career applicant is suited to an internship. Use the blank template below as a starting point, then tailor it with accurate examples of the applicant’s work, strengths, and readiness for the role.
What an Internship Recommendation Letter Does
A recommendation letter gives an internship decision-maker another perspective on an applicant’s abilities and work habits. It is usually written by someone who has seen the applicant perform in a relevant setting, such as a class, research project, volunteer role, part-time job, or previous internship. The letter should complement the resume and application rather than repeat them.
A useful letter makes a clear case: it identifies the relationship between recommender and applicant, describes relevant skills with evidence, and explains why those skills fit the opportunity. It does not need dramatic praise or a long account of every achievement. A focused page with credible examples is often more persuasive than several pages of general compliments.
Internship requirements vary. Some employers ask for a formal signed letter, while others collect references through a form or request a recommendation only after an interview. The applicant should confirm the requested format, deadline, delivery method, and any prompt before asking someone to write. A letter drafted for one role may not answer another role’s questions.
Before You Agree to Write One
A recommender should accept only if they can honestly and specifically support the applicant. Being asked is not an obligation to provide an unreserved endorsement. If you know the applicant only slightly, have not observed the relevant skills, or cannot meet the deadline, a courteous explanation gives them time to find a better reference.
First, consider what you can speak to firsthand. A professor may be able to discuss analytical work, reliability in a course, and contributions to a project. A supervisor might address follow-through, communication, and how the applicant handled feedback. Avoid claiming knowledge of qualities you have not observed or predicting that the applicant will excel in a setting you do not understand.
Before starting, ask the applicant for the information needed to write accurately:
- The internship description, organization, team, and any stated selection criteria.
- The application deadline, submission instructions, recipient name if available, and requested length or format.
- A current resume or concise summary of relevant experience, projects, coursework, and accomplishments.
- How you know each other, including the dates or setting in which you worked together.
- Any particular skill or example they hope you can address, while making clear that you will use your own judgment.
Keep the applicant’s materials private and use them only for the recommendation. If you cannot support the request strongly, say so promptly and respectfully rather than writing faint praise that could mislead the applicant about how helpful the letter will be.
Gather Specific Details Before Drafting
Strong recommendations rely on observable details. Before writing, review the work you supervised or taught and make brief notes about concrete moments. For example, “prepared a clear weekly summary” is more informative than “has excellent communication skills.” A project result can be useful, but describe the applicant’s own contribution rather than assigning them credit for a team’s entire achievement.
Choose one or two examples that connect to the internship. A design applicant might have revised a prototype after user feedback; a research applicant might have organized records carefully and explained a finding to classmates; an operations applicant might have managed a recurring task without needing reminders. The example does not have to be extraordinary. It should be relevant, accurate, and detailed enough to show what the applicant did.
Check names, dates, titles, and pronouns with the applicant or reliable records. Do not include confidential grades, health information, personal circumstances, or sensitive details unless the applicant has clearly asked you to share them and they are appropriate to the request. In most cases, the letter can discuss performance without disclosing private information.
Recommended Structure and Tone
Most internship recommendation letters can be organized into a few short parts. The opening identifies the recommender and states the recommendation. The middle explains the relationship and gives evidence of relevant strengths. The closing summarizes the endorsement and provides a way to follow up. A formal letter may include the date, recipient details, and a signature block; an online form may need only the body text.
- Greeting and purpose: Address a named recipient when the applicant provides one. Otherwise, use a neutral greeting such as “Dear Internship Selection Committee.” State who you recommend and, if known, for which opportunity.
- Relationship and context: Explain your role, how you know the applicant, and the period or setting in which you observed their work.
- Evidence: Describe a small number of relevant strengths and support them with examples. Include a clear comparison only if you have a fair basis for it.
- Fit and closing: Link the evidence to the internship’s stated needs, restate your level of support, and offer contact details if you are comfortable receiving follow-up.
Use a professional, natural tone. “I recommend Maya for this research internship” is clearer than a string of exaggerated adjectives. Be direct about the strength of your endorsement; do not imply a stronger relationship or level of certainty than you actually have. A letter can be warm while remaining measured and truthful.

Short Filled-In Sample
Sample — all names and details below are fictional.
Dear Internship Selection Committee,
I am pleased to recommend Jordan Lee for the summer materials research internship at Northstar Materials Lab, a fictional organization. I teach introductory chemistry at Cedar Ridge College and supervised Jordan’s class research project during the spring term.
Jordan stood out for careful record-keeping and a willingness to revise work in response to evidence. In the project, Jordan noticed that two measurements had been recorded under different conditions, flagged the inconsistency, and repeated the comparison before presenting the results. Jordan also explained the limitation clearly to the group rather than overstating what the data showed.
These habits—attention to detail, thoughtful communication, and openness to feedback—would be useful in a supervised research setting. I recommend Jordan for the internship. Please contact me at recommender@example.test if further information would be helpful.
Sincerely,
Alex Morgan
Science Instructor, Cedar Ridge College
The sample illustrates the role of evidence: it describes a specific action and explains why that action matters. Replace its fictional details with observations you can verify, and do not copy claims that do not fit the applicant.
Tailoring the Letter to the Internship
Read the internship description and identify its actual requirements. If it emphasizes collaboration, discuss a real example of working with others. If it calls for careful documentation, use an example that demonstrates accuracy and consistency. Avoid guessing at hidden preferences or claiming the applicant meets a technical requirement unless you have a sound basis for saying so.
Tailoring does not mean reshaping the facts. It means selecting the most relevant true details and explaining the connection. An applicant may have many strengths, but a letter becomes clearer when it focuses on two or three that matter for this particular role. If the opportunity is in a field outside your expertise, be candid about the limits of your knowledge and concentrate on qualities you have directly observed.
When an applicant is applying to several internships, ask whether separate letters are required. If a general letter is appropriate, keep it broad enough to remain accurate, but avoid naming a particular role that does not apply. For different opportunities with different criteria, a tailored version is usually more useful than a single letter with mismatched details.
Common Problems to Avoid
- Generic praise: Claims such as “hardworking” or “bright” need context. Add a brief example showing the quality in action.
- Unsupported comparisons: Do not call someone the best student or employee you have ever known unless you can honestly substantiate that comparison.
- Overstatement: Avoid promises about future performance. Describe observed preparation and explain why it is relevant instead.
- Unclear relationship: State your role and how you know the applicant so the reader can understand the basis of your perspective.
- Too much background: A long biography can bury the recommendation. Keep the focus on evidence connected to the internship.
- Errors or inconsistencies: Verify names, role titles, dates, and the recipient’s instructions before sending.
A related misconception is that a recommendation is more convincing when it sounds grand or uses formal language. In practice, clarity and credibility matter more than inflated wording. A modest, specific account of a real contribution is more useful than a sweeping claim with no supporting example.
Formatting, Sending, and Follow-Up
Follow the recipient’s instructions first. If the request specifies a web form, file type, subject line, or direct submission, use that method rather than sending an extra copy elsewhere. If no format is specified, a concise letter on professional letterhead, where appropriate, can include the date, recommender’s contact information, greeting, body, and signature. Use a readable font and check that the final file opens and is legible.
Confirm whether the applicant or recommender is responsible for submission. Some processes ask recommenders to send a letter directly; others ask the applicant to upload it. Do not assume that handing the applicant a copy satisfies the instructions. If a confidential submission is requested, follow the stated process and do not promise confidentiality beyond what the process provides.
Agree on a realistic deadline with enough time to review the final version. Submit early when possible, then notify the applicant that it has been sent. If you encounter a delay or cannot complete the letter, tell the applicant promptly so they can make another arrangement. Keep a copy for your records only in line with your workplace or institution’s policies.
Frequently Asked Questions
Who should write an internship recommendation letter?
Choose someone who has directly observed relevant work, learning, or conduct and can provide specific examples. A teacher, project supervisor, employer, or volunteer coordinator may be suitable. A prestigious title alone does not make a reference useful if the person barely knows the applicant.
How long should an internship recommendation letter be?
Follow the application instructions if they set a limit. Otherwise, a focused letter of roughly one page is a practical target, though the right length depends on the form and the evidence available. Remove repetition rather than adding material simply to make the letter longer.
What if I cannot recommend the applicant strongly?
Tell the applicant promptly and privately that you may not be the best person to write the letter. You can explain that you are unable to provide a sufficiently specific endorsement without criticizing them. An honest refusal gives them a chance to ask someone better positioned to support their application.
Can an applicant draft their own recommendation letter?
Some recommenders may ask for a resume, examples, or a factual summary to make drafting easier. If asked to prepare a draft, provide accurate information and leave the recommender free to edit, reject, or rewrite it. The recommender should approve the final wording and submit it as required.
Should the letter include a weakness?
Usually, the letter should focus on relevant strengths rather than volunteering unrelated criticism. If the application asks about development areas, answer honestly and constructively, with appropriate context. Do not conceal a material issue when the prompt directly asks about it, and do not speculate about matters you have not observed.
