A recommendation letter plays a key role in jobs, internships, and academic applications, as it provides third-party insights that resumes and cover letters don't offer. A strong letter can set someone apart and help reviewers grasp their suitability for a position or program.
This article explains in more detail what a letter of recommendation is, when it is needed, how to write one effectively, and common mistakes to avoid. We also provide examples and a versatile template that you can adapt to your needs.
Key Takeaways
A recommendation letter is written by someone (usually a past employer or professor) who can vouch for your experience, expertise, and character.
These “testimonials” usually accompany applications for jobs, internships, fellowships, and higher education opportunities.
To write one, start by introducing yourself and your relationship with the applicant; this establishes your perspective and the weight of your letter.
In the body of your letter, clearly highlight the applicant’s hard and soft skills, achievements, and traits with examples and anecdotes.
You can conclude with a firm endorsement, like “I wholeheartedly recommend [Applicant’s name]” and your contact details, including your email and phone number.
What Is a Letter of Recommendation and When Is It Needed?
A recommendation letter is a formal document written by someone who knows you professionally, academically, or personally, vouching for your character, skills, and achievements.
Unlike a resume, which lists facts, a recommendation letter provides personal insight about your qualifications. It can increase callbacks by 60% and support your credibility and suitability for:
Job applications. Employers may request a letter of recommendation to assess your experience and expertise. Sometimes, this is reviewed alongside a job reference letter, which serves a similar role as your "testimonial" but isn't tailored to a specific opportunity.
Internships and fellowships. These programs typically require recommendations to evaluate your potential in a professional setting. They also gauge your commitment and overall character.
Higher education admissions. Students submit recommendation letters from their teachers or academic advisors to universities and colleges for applications, scholarships, or graduate programs. These help admissions committees contextualize students' academic performance and determine fit.
Professional certifications. To earn certain professional certifications, you will need to provide proof of your character or competency through letters of recommendation. For example, to become a Certified Business Analysis Professional (CBAP), you need two references to confirm your 7,500 hours of experience.
Immigration applications. In the U.S., recommendation letters aren’t usually legally required, however, they can strengthen your case in immigration cases. They are often critical supporting evidence for EB-1, O-1, or EB-2 National Interest Waiver (NIW).
Volunteer roles. Some organizations will want a letter of recommendation to confirm your work ethic, skill set, and personality. It is common if the role involves high levels of trust, safety risks, or specialized skills.

How to Write a Letter of Recommendation
Follow these four steps to write a letter of recommendation:
#1. Introduce Yourself and Your Relationship
Start your letter by clearly introducing yourself and your connection to the applicant; this includes:
Stating your job title, position, organization, and relevant experience to establish credibility
Explaining how you know the applicant and for how long
This context helps the reader understand your perspective and the weight of your recommendation. So, you should be specific about the nature of your relationship, such as overseeing their work on projects or collaborating with them in a team.
This doesn’t have to be long; it just needs to set the stage for the rest of the letter and reassure the reader that your insights are informed.
#2. Highlight Key Skills and Achievements
The goal is to support the applicant's case, so focus on their standout skills, accomplishments, and qualities that relate directly to the opportunity they are seeking. You should avoid vague praises and use concrete examples instead. It helps to use the STAR method to structure these examples. Mention projects they led or ways they went above and beyond in their work.
Your examples should highlight the applicant's hard and soft skills. If these align with what they wrote in the resume and cover letter, even better! This way, a reviewer can see consistency across the applicant’s materials, which makes the recommendation more convincing. Specific anecdotes also make the applicant more memorable.
#3. End with a Strong Recommendation
A strong closing reinforces the impact of the letter and ties together the examples and unique skills you highlighted.
You should conclude with a clear, confident statement of your endorsement. This means avoiding ambiguous language and directly affirming that you recommend the applicant for the opportunity.
This section should leave no doubt in the reader’s mind about your support. Therefore, use phrases like “I wholeheartedly recommend” or “I am confident they will excel” to show conviction.
#4. Leave Your Contact Information
Finally, provide your contact details to let the reader follow up with any questions. You should include your email and phone number, and mention you are happy to discuss the applicant further if needed.
This adds credibility to your letter and demonstrates your transparency, showing that you stand behind your recommendation. It also makes it easy for the person reviewing the letter to verify details or gain additional insights.
4 Common Mistakes to Avoid When Writing a Letter of Recommendation
Avoid these four common mistakes to write a stellar letter of recommendation:
Being too vague. Making empty praises like "They are a great person" without backing them up doesn't give the reviewer a clear sense of why the applicant stands out or is suited for the role. Therefore, you should always concentrate on concrete examples of achievements, skills, and behaviors.
Not tailoring the letter. Unlike a reference letter, a recommendation letter should address the specific opportunity. Talk about skills and experiences that are directly relevant to the applicant's position, program, or scholarships. This signals that you have considered the applicant’s abilities and the expectations of the position, which adds weight to your endorsement.
Overloading the letter. While examples are important, packing in too many details can overwhelm the reader. You should focus on the most impressive or relevant achievements and keep the letter concise. Three to five strong examples usually provide enough evidence.
Writing hesitantly. Avoid qualifiers like “I think they might be good” or pointing out weaknesses. The goal is to support the applicant. If you cannot give a strong recommendation, it is better to politely decline than risk a lukewarm letter.
How to Request a Letter of Recommendation Professionally
To request a letter of recommendation, start by explaining why you are asking them and what the opportunity is. Be clear about deadlines and any specific points you would like them to address. You can request in person or by email:
In person. Approach the person politely and ask if they have time to discuss a recommendation. You must respect their time and ask if they feel comfortable writing a strong, tailored letter. Bring any relevant materials, like your resume or a summary of achievements, so they have context.
Over email. Politely ask if they are willing to write a recommendation and offer to provide any additional information. You should provide them with context about the opportunity and attach supporting documents along with the deadline, so they can make their decision. At the end, thank them for their time and consideration.
