A letter of recommendation, often shortened to LOR, is one of the few parts of a university application that isn't written by the applicant. It comes from someone else, a teacher, a professor or an employer. That outside voice carries real weight. Admissions committees read hundreds of applications where grades and test scores look similar. An LOR is often what separates one candidate from another.
This guide covers how to write a letter of recommendation for both a bachelor's application and a master's application. The two are not the same. They ask for different recommenders, different content, and different lengths. We'll walk through both, then give you a ready-to-use template for each one.
What Is a Letter of Recommendation, and Why Does It Matter?
An LOR is a formal document written by someone who knows the applicant's work firsthand. It could be a teacher, a professor, a manager, or a project supervisor. The letter tells the admissions committee what that person has observed: the applicant's abilities, character, and potential for success.
Grades and test scores are numbers. A recommendation letter is a human account. These letters help admissions officers see beyond test scores and connect the dots about who you are and why you will be a strong fit for their program. That's the entire point of the exercise.
Importance for Bachelor's Applicants
A high school student doesn't have a research history or years of work experience yet. What they do have is a track record in the classroom and outside of it. For a bachelor's application, the LOR is often the only place where an admissions officer gets a sense of the applicant as a person, not just a transcript. It can speak to curiosity, resilience, and how someone behaves when things don't come easily.
Importance for Master's Applicants
At the master's level, the letter does different work. It's expected to speak to academic readiness: research aptitude, analytical thinking, and whether the applicant can handle independent, graduate-level study. A master's program is taking a bet on someone's future performance, and the LOR is one of the few pieces of evidence that isn't self-reported.
LOR for Bachelor's vs. LOR for Master's: Key Differences and Who Should Write It
Table 1: LOR for Bachelor's vs. LOR for Master's
| Factor | Bachelor's/UG | Master's |
|---|---|---|
| Typical recommender | High school teacher, counselor, or department head | Professor, project supervisor, or employer |
| Letters typically required | 1–2 | 2–3 |
| Typical word count | 400–500 words | 400–800 words |
| Main focus | Character, potential, classroom engagement, extracurriculars | Research aptitude, academic performance, analytical ability |
| Required everywhere? | No. Undergraduate admission in several countries relies mainly on transcripts, so an LOR isn't always requested | Close to universal for international master's applications |

Who should you ask?
If you're applying to a bachelor's program, go with a teacher who taught you recently, ideally in a subject connected to what you want to study, plus your school counselor. Someone who knew you years ago isn't the right choice. Colleges want to know who you are now.
If you're applying to a master's program, the right recommender is someone who supervised your work directly, a professor who guided a research project, or a manager who watched you perform on the job. Seniority alone doesn't matter here. A recommender with a big title who barely knows you produces a weak letter, no matter how impressive their name looks on the letterhead.
Academic LOR vs. Professional LOR
If you're applying to a master's program, you'll likely need to decide between two types of letters.
An Academic LOR comes from a teacher or professor at your most recent institution. It focuses on your academic performance, your analytical and research skills, and how you handled coursework or a specific project. Most research-based master's programs, MS, MSc, Meng, expect this type.
A Professional LOR comes from a supervisor in a workplace setting. Instead of grades and coursework, it covers your adaptability on the job, how you handled team projects, your problem-solving under pressure, and your expertise in your field. This type is especially common for MBA applications and other management-focused programs.
Most master's applicants will need at least one academic letter. Some programs, particularly MBAs, will also want one professional letter alongside it.
LOR Structure and Format
Every strong LOR, whatever the level, follows roughly the same three-part shape.
- Introduction: The recommender states who they are, their role, and how they know the applicant. This section should include how long they've known the person and in what context, a class, a lab, a job.
- Body: Two or three qualities, each backed by a specific example. This is not the place for vague compliments. For example, saying “She's a hard worker” says nothing. "She rewrote the team's data pipeline in two days when our original approach failed" says everything.
- Conclusion: A clear, direct endorsement, plus the recommender's contact details in case the university wants to follow up.
The letter should be on official letterhead where possible, since this adds credibility and helps the admissions committee confirm it's genuine. For length, aim for roughly 400–500 words for a bachelor's application, and 400–800 words for a master's application. Longer isn't better here, a padded letter usually means the recommender didn't have much specific to say.

Tips for Writing an LOR for Top-Ranked MS Programs
Most of what we’ve covered so far holds true across the board. But once you’re aiming at a program with a single-digit acceptance rate, the letter gets read with a different set of eyes, and it’s worth knowing what changes.
- Who is the writer: That’s the starting point. At very top schools, the recommender’s own background carries real weight, so don’t just pick anyone who is available and is willing to write you a recommendation.
You need someone who’s spent time at a comparable institution, knowing what that admission committee is looking for, in a way a stranger to that world can’t fully replicate. Its not decisive on its own, but at the margin, it counts more here than it would at a mid-tier program.
- Ranking is important: Recommendation forms frequently ask the writer to rank the candidate against others they’ve taught. In schools with a reasonable acceptance rate, checking excellent is plenty. Your recommender needs to be checking something closer to “one of the best I’ve taught in my career”. That gap matters enormously; it’s a conversation worth having with your recommender directly, rather than hoping they’ll get it right by instinct or experience.
- Number of letters: If you’re submitting more than one letter, think about them as a set, not as duplicates. Three recommenders independently praising your work ethic tells the committee nothing they didn’t already assume. So, this means that each letter should be doing separate work, pointing out evidence that you can actually bring something to the table.
- Name of recommenders isn’t everything: Don’t mistake a famous name for a strong letter. A recommender can be well-known and still write something forgettable if they didn’t really work with you. Just stating random and vague statements by a renowned professor doesn’t prove anything about you and the committee can see the writer doesn’t really know you and your potential.
The gap is impossible to hide at a school where every applicant’s LOR gets read by someone who’s seen thousands of these letters. A detailed, specific letter from someone who actually supervised your work will beat a vague one from someone impressive.
- New and genuine data about the applicant: Letters that just restate what’s already on the applicant’ resume aren’t adding anything new. The point of an LOR is to say something the rest of the applicant can’t. Opening with the general statements such as “to whomsoever it may concern” isn’t just a minor error, it can seriously have an impact. It’s better to write directly to the admissions committee.
- Timing matters: Choosing the right and appropriate time is more important than many people assume. Asking for an LOR too close to the deadline usually produces a rushed, generic letter, since the recommender doesn’t have room to think carefully. Missing the deadline altogether is worse still, plenty of universities simply won’t accept late materials, no exceptions made.
Should You Use AI to Write Letter of Recommendations?
The reality on the ground shows that its already happening on a much bigger scale than most applicans realize. Close to 31% of applicant had already turned to generative AI for help writing a college recommendation letter, mostly to save time and cut down on stress. Although the practice is common, the policy is not clear from many schools or even nonexistent, even institutions with strict rules about AI in students’ essays. So where does that leave an applicant? A few things are worth pulling apart.
Using AI to draft an outlie is fine, writing the whole letter no. If the recommender asks you to draft the letter yourself, which happens more often than people admit, AI can help you organize your achievements into a clean outline. Treat it as a structuring tool, not a replacement for the actual substance. The letter still needs real, specific detail that only you or your recommender can supply. AI can help shape the information into a raedeable format; it can’t be used to write a unique and personalized LOR based on your resume and skills.
AI can’t produce genuinely informative letters. A peer-reviewed study in a medical journal tested exactly the impact of AI on LOR. Researchers built AI version of real recommendation letters and asked program directors to tell them apart from human-written originals. The human-written letters were full of concrete, checkable details including how long the recommender had known the applicant, specific research experiences and particular things they had personally observed. The AI-generated versions read smoothly on the surface, but once you looked past the polish, they were noticeably more generic underneath.
An experienced reader notices a generic letter without needing any algorithm to flag it. This is because they’ve read hundreds of these letters and can tell when one could describe almost anyone. AI-Detection software isn’t reliable either. The actual flag is never getting caught by AI-detection software. It’s handing over a letter that reads as hollow to a real person reading it.
AI works well as a structuring tool, whether you're an applicant organizing your own outline or a recommender organizing their thoughts before writing. It becomes a problem the moment it replaces the specific, personal knowledge that's supposed to be the entire reason the letter is worth reading in the first place.
FAQs
Should I waive my right to see my letter of recommendation?
Generally, yes. Waiving your right to view the letter can make it appear more trustworthy to an admissions committee because it indicates that the recommender was able to provide their assessment independently. Harvard’s graduate school notes that students can access recommendation letters in their academic records after enrollment only when they have not waived that right. For applications, however, waiving the right is typically the standard approach.
What if I don't have anyone to ask for an academic letter of recommendation?
This is a common concern, particularly among applicants who graduated several years ago or no longer have strong relationships with their professors. In these situations, a current or former employer, manager, or professional supervisor may be able to provide a suitable recommendation, especially if they can demonstrate your abilities in areas such as research, communication, critical thinking, or analysis.
What should I do if my recommender asks me to write the letter myself?
Although it may feel unusual, this situation does occur. Instead of writing a final letter entirely on your own, consider giving your recommender a detailed summary of your accomplishments, experiences, and qualities you would like highlighted. They can then use that information to prepare the recommendation in their own words, review the final draft, make any necessary changes, and approve it before submission. The recommendation should ultimately reflect the recommender’s genuine perspective and writing style.
Can my letter of recommendation be written in a language other than English?
In many cases, yes. Some universities allow recommendation letters written in another language as long as they are accompanied by an official English translation. For example, Dartmouth’s admissions guidance states that translated letters should be signed and dated by the translator. Because requirements differ between institutions, make sure you review the specific instructions for every university you apply to. Some may also require the original letter to be submitted together with its translation.
Can a family member write my letter of recommendation?
It is usually better to choose someone outside your family. A recommendation from a relative may be viewed as less impartial because of the personal relationship. Whenever possible, select an academic, professional, or other qualified person who can provide an objective assessment of your abilities and character.
How many letters of recommendation do I actually need?
The number depends on the degree and institution. Undergraduate applications commonly request one or two recommendation letters, while master’s programs often ask for two or three. Since requirements can vary significantly, always check the application instructions for the particular university and program.
Do I need a letter of recommendation for a bachelor's degree, or only for master's?
There is no universal requirement. Recommendation letters are much more common for graduate applications, but undergraduate requirements differ depending on the country, university, and program. For instance, some Canadian universities do not require recommendation letters for undergraduate admission. Always review the official admissions requirements rather than assuming an LOR is necessary.
Does the letter of recommendation have to come from a professor or supervisor specifically?
Not necessarily. A recommendation can come from another person who has worked closely with you and can provide meaningful insight into your skills, achievements, and potential. This could include a mentor, academic advisor, or another professional. However, when a program specifically requests an academic or professional recommendation, it is important to follow those instructions and choose someone whose relationship with you matches the stated requirement.
How far in advance should I ask for a letter of recommendation?
Ideally, contact your recommender at least four to six weeks before the application deadline. Giving them sufficient notice allows them to prepare a thoughtful letter and gives you time to send a reminder or address any issues before the submission deadline.
Can I reuse the same letter of recommendation for more than one program?
You can, provided the recommendation is broad enough to apply to multiple programs and the application systems permit it. A general letter can work when it focuses on transferable strengths and accomplishments. However, recommendations that address the specific program, field, or opportunity can provide more relevant context, so customization may be preferable when possible.
Does a letter of recommendation need to be on official letterhead?
Many institutions and organizations prefer or require recommendation letters to appear on official letterhead. It can help establish the recommender’s institutional or professional affiliation and verify where the letter originated. However, this is not a universal requirement, so check the submission guidelines for each program before assuming letterhead is necessary.
What happens if my recommender misses the deadline?
A late recommendation can create a problem because universities have different policies regarding incomplete or late application materials. If your recommender misses the deadline, contact the admissions office as soon as possible and explain the circumstances. The admissions team can tell you whether the letter can still be accepted or whether any alternative arrangements are available.
