How to Write a Letter of Recommendation (With Examples)
A letter of recommendation is a formal document written by someone who can speak to your skills, character, work ethic, academic success, or career achievements. It is usually written by a manager, professor, mentor, colleague, or supervisor and used to support applications for jobs, internships, scholarships, and other opportunities.
The pressure cuts both ways. If you're the one being asked, you want to do right by the person who trusted you with something this significant. Meanwhile, if you're the one requesting the letter, you need to know how to ask, who to approach, and what to give your recommender so they can write something compelling.
This guide covers everything: what a letter of recommendation is, the different types, what to include, how to format it, and how to ask for one, even if that feels awkward.
- A letter of recommendation is written by someone who can directly speak to an applicant’s skills, character, achievements, or academic potential.
- The strongest ones are specific to the opportunity and include concrete examples, measurable achievements, and a clear endorsement.
- Different types of these letters focus on different strengths, from workplace performance and academic ability to character, integrity, and collaboration.
- Writers should only agree to provide a recommendation if they can write a genuinely strong letter, since a vague or lukewarm one can hurt the applicant.
- Anyone who asks for a recommendation should give the writer enough context, including a resume, deadline, role or program details, and key achievements to highlight.
What Is a Letter of Recommendation?
A letter of recommendation is a document written by a third party that validates a candidate's qualifications, character, and suitability for a specific role or program. It should come from someone who has directly observed their work, academic performance, or character, and is willing to vouch for them.
Recommendation letters are typically written by managers, professors, mentors, or senior colleagues. The audience ranges from hiring managers and HR departments to college admissions committees and scholarship boards, whoever is evaluating the applicant's candidacy.
It's worth distinguishing it from two documents people often confuse it with: cover and reference letters.
- A cover letter is written by the applicant themselves and makes a case for their own fit.
- A general professional reference letter isn't tied to any specific opportunity; it's more of a blanket endorsement someone might carry from employer to employer. A proper letter of recommendation is written for a particular job, program, or award.
Recommendation letters hold substantial weight in admissions decisions, as employers can use them to assess character and work ethic in ways a resume simply can't capture.
Types of Letters of Recommendation
Not all recommendation letters are the same; the right type depends on who is writing it and what the applicant is applying for. Here's a breakdown of the five most common formats.
| Type | Who Writes It | Who Reads It | Focuses On | Typical Length |
|---|---|---|---|---|
Job | Manager or supervisor | Hiring manager | Skills, results, work ethic | 1 page |
College | Teacher or counselor | Admissions committee | Academic potential, character | 1 page |
Graduate School | Professor or mentor | Admissions board | Research ability, readiness | 1–2 pages |
Character Reference | Mentor or community leader | Employer or institution | Values and integrity | 1 page |
Coworker/Employee | Peer or manager | Hiring manager | Collaboration, dependability | 1 page |
#1. Letter of Recommendation for a Job
Written by a former manager, supervisor, or senior colleague, a professional letter of recommendation focuses on measurable contributions, skills, and work ethic. Sometimes called an employment reference letter, it's commonly required for competitive roles or senior positions where character verification goes beyond the interview.
#2. Letter of Recommendation for College
These come from high school teachers, school counselors, or coaches and focus on academic potential, intellectual curiosity, and community involvement. They're typically submitted alongside transcripts and personal essays during undergraduate admissions, and admissions committees read them closely for signals that grades alone can't convey.
#3. Letter of Recommendation for Graduate School
Written by a professor or academic mentor, graduate school letters need to demonstrate research ability, critical thinking, and readiness for advanced academic work. They often run up to two pages (more detailed than job or college letters) because the audience expects evidence of scholarly potential instead of general praise.
#4. Character Reference Letter
A character reference is written by someone who knows the person personally: a community leader, mentor, or long-term family friend. It’s typically used when professional or academic references aren't available and focuses on integrity, values, and personal qualities rather than professional achievement. Courts, scholarships, and nonprofits often request this type.
#5. Letter of Recommendation for an Employee or a Coworker
This type is usually written by a peer or direct manager, and it highlights collaboration, specific workplace contributions, and dependability as part of personal leadership. It's particularly useful when a professional doesn't have a direct supervisor available, or when a team member can speak to day-to-day working dynamics more authentically than a senior leader with limited contact.
What to Include in a Letter of Recommendation
A letter of recommendation should include an introduction establishing your relationship to the applicant, examples of their skills and achievements, and a solid closing endorsement. Each component has a job to do; if you skip one, the whole letter may lose credibility or impact.
#1. Your Introduction and Relationship to the Applicant
Open by explaining who you are, your role, and how long you've known the candidate and in what capacity. This establishes credibility before anything else. Readers need to trust the source before they trust the endorsement.
#2. A Strong Opening Statement
Lead with a clear, enthusiastic endorsement without passive or reluctant openers. For instance, let’s compare these:
- Weak: "I was asked to write this letter on behalf of Sarah Chen."
- Strong: "It is my pleasure to recommend Sarah Chen for this role without reservation."
- Also strong: "I have no hesitation in saying that Marcus is one of the most capable analysts I've managed in fifteen years."
That first sentence sets the emotional tone, so you should make it count.
#3. Specific Examples and Measurable Achievements
This is the most important section of the letter. Vague praise, such as "she is a hard worker," does nothing; you need to do your best to explain how hard the person works. Yet, examples with quantified results, such as "she increased team output by 30% over two quarters while onboarding three new hires," can make a true difference.
Aim for at least two concrete examples, and if you can quantify a result, include the number. If you can't, describe the situation and outcome with enough detail that the reader can visualize it.
#4. Skills and Qualities Relevant to the Opportunity
Before writing, review the job description or program requirements and tailor what you write to that. A letter that connects the candidate's strengths to the specific role is far more persuasive than a generic one.
For example, if the job requires project leadership and you have a great story about the candidate leading a cross-functional initiative, that story belongs in this letter.
#5. A Closing Endorsement and Contact Information
End with a direct, confident summary that recommends the applicant one final time. Keep it to one or two sentences, as there’s no need to recap everything. Once you’re done, include your full name, title, email address, and phone number below.
What Format to Use for a Recommendation Letter?
The standard recommendation letter format follows a business letter structure, typically one page long, written in a 12-point professional font such as Arial or Times New Roman. Margins should be one inch on all sides, and the tone should remain formal and clear throughout.
Use official letterhead when possible, as it reflects credibility and professionalism. For job applications, keep it to one page; graduate school letters can extend to two pages if you genuinely have enough substance to fill them.
Here's the structure you should follow:
5 Steps on How to Write a Letter of Recommendation
You can write a letter of recommendation by following these easy steps:
If you can't write a genuinely enthusiastic recommendation, decline politely and without elaborate explanation, as a lukewarm letter can do as much damage as a negative one. Admissions committees and hiring managers read dozens of these letters and can spot hedging language immediately.
Alternatively, you can offer to help the applicant find someone better positioned to advocate for them.
Ask to see the applicant’s resume, the job description or program requirements, a list of achievements they'd like highlighted, the submission deadline, and the format (email, portal upload, or physical letter).
Also, ask them which qualities or stories they most want emphasized. The more context you have, the more specific and persuasive the letter will be.
Choose two or three specific stories or achievements that best represent the candidate in relation to this particular opportunity. A focused letter built around a handful of strong examples will do much better than a sprawling one that tries to cover everything.
Devote one paragraph to each key quality or achievement. It’s best to use the STAR format (Situation, Task, Action, Result) to frame each example clearly and concisely, e.g., "She managed a five-person team that delivered the product two weeks ahead of schedule".
Read the letter aloud; this will help you catch awkward phrasing that silent reading misses. Alternatively, have a colleague review it if the stakes are high, and then submit ahead of the deadline. A late recommendation reflects poorly on the applicant, not just the writer.

Dear Hiring Manager,
It is my genuine pleasure to recommend Penny Halt for the Senior Marketing Manager position at your organization. I served as Penny’s direct supervisor at Apex Digital Group for two years, and she is, without question, one of the most capable marketing professionals I've worked with in my career.
Penny joined our team as a marketing coordinator and quickly demonstrated a rare combination of creative instinct and analytical rigor. In her first year, she led a content campaign for a mid-market SaaS client that increased qualified lead generation by 40% over six months. These were the results that earned the client a renewed contract and significantly expanded our engagement scope. She managed that project independently, from strategy through execution, while simultaneously supporting two other accounts.
What set Penny apart during a particularly difficult product launch (one where the client changed requirements midway through) was her composure and her ability to rally the team. She restructured our timeline, redistributed tasks without anyone missing a deadline, and presented the revised plan to the client with confidence that turned a tense situation into a stronger working relationship. That kind of leadership isn't something you can train; she brought it in the door.
Penny is ready for a senior role, and I have no hesitation in recommending her for this position. Please feel free to contact me at the details above if you'd like to discuss her work further.
Sincerely,
Jordan Meyers
Marketing Director, Apex Digital Group

Dear Admissions Committee,
I am writing to recommend Daniel Osei for admission to your undergraduate program with my full and enthusiastic support. I've taught AP English Language and Composition at Westlake High School for sixteen years, and Daniel is among the most thoughtful and genuinely curious students I've had the privilege of teaching.
Daniel came into my class as a strong writer, but what distinguished him was his instinct for asking the harder question. When we read Joan Didion's "The Year of Magical Thinking" as part of our unit on personal narrative, Daniel submitted an essay that examined how grief distorts perception of time. It was the kind of analysis I'd expect from a college junior. He revised it twice, unprompted, because he felt his original argument wasn't precise enough.
Beyond the page, Daniel's presence in the classroom discussion raised the quality of everyone else's thinking. He challenged ideas respectfully and genuinely listened when others pushed back. Over the course of the year, I watched several quieter students become more willing to speak up, in part because Daniel made the conversation feel safe.
He has grown remarkably in the two years I've known him, and I believe he'll thrive in a rigorous academic environment. I recommend him without reservation.
Sincerely,
Patricia Connolly
AP English Teacher, Westlake High School

Dear Hiring Manager,
I'm writing to recommend my colleague, Tess Nakamura, for the Product Operations Manager role at your company. Tess and I worked together on the same product analytics team at Northgate Solutions for three years, collaborating closely on several high-priority initiatives, and I can speak directly to the quality of her work.
Our most significant joint project was a data infrastructure overhaul that affected reporting for six product lines. The project had an aggressive timeline (twelve weeks) and required coordinating across engineering, finance, and two external vendors. Tess owned the communications layer: she set the meeting cadence, tracked every dependency, surfaced blockers early, and kept all parties aligned without ever being heavy-handed about it. We delivered on time. I genuinely don't think we would have without her.
What I'd highlight most is her reliability under pressure. When requirements shifted three weeks before launch (which they did, significantly), Tess absorbed the change, reprioritized quickly, and brought the team back into focus without drama. That kind of steadiness is genuinely rare, and it's the thing our team depended on most.
She'd be a strong addition to any team that values both execution and collaboration. I recommend her without hesitation.
Sincerely,
Ramon Delgado
Senior Product Analyst, Northgate Solutions
Final Thoughts
A letter of recommendation is one of the most valuable things a trusted professional or educator can provide to a job seeker or student.
When written with care, specificity, and real enthusiasm, it can genuinely tip the balance in a competitive application process. After all, the difference between two equally qualified candidates often comes down to how well a third party can articulate what makes one of them worth taking a chance on.
For both writers and requesters, preparation is everything. The more information changes hands upfront, the stronger the final letter will be. It's a collaborative process, even if only one person's name appears at the bottom.
Once the letter is ready, make sure the rest of the application package matches its quality. Our resume builder and cover letter examples can help you put together supporting documents that complement a strong recommendation rather than undercut it. This way, you’re in for better chances when it comes to landing an interview!
