LOR for Study Abroad – Quick Reference

Question	Answer
What is an LOR?	A Letter of Recommendation is a formal document written by someone who has directly worked with or supervised you – a professor, manager, or supervisor – endorsing your abilities and potential for the program you are applying to.
How many LORs do I need?	Most universities require 2-3 LORs. MS/MBA programs typically want 1-2 academic + 1 professional. Check each program’s specific requirements.
Who should write it?	Someone who knows your work directly – a professor who taught your coursework or supervised research, or a manager/supervisor from an internship or job. Never a family member or friend.
How long should it be?	400-600 words, one page maximum. On official letterhead where possible.
Academic vs Professional LOR?	Academic: written by a professor, focuses on intellectual ability and academic performance. Professional: written by a manager/supervisor, focuses on workplace skills and leadership.

What is a Letter of Recommendation (LOR)?

A Letter of Recommendation is a formal endorsement written by someone who has supervised, taught, or worked closely with you. It tells the admissions committee things your SOP and transcript cannot – how you perform under pressure, how you work with others, and what you are like to have in a classroom or on a team.

Global universities consider LORs a core qualitative factor in admissions, contributing 15-30% collectively to the overall evaluation, especially for postgraduate, MBA, and PhD programs. A strong LOR can tip a borderline application in your favor. A weak or generic one can undermine an otherwise strong profile.

The key word is credibility. The LOR works precisely because it comes from someone other than you. This is why the relationship between recommender and applicant matters as much as what the letter says.

Academic LOR vs Professional LOR – Key Differences

Element	Academic LOR	Professional LOR
Written by	Professor, department head, research supervisor, academic advisor	Manager, team lead, internship supervisor, senior colleague
Focuses on	Intellectual ability, academic performance, research potential, classroom contributions	Work performance, leadership, teamwork, problem-solving, professional growth
Best for	MS, PhD programs, research-heavy applications	MBA, management programs, career-focused Masters, any program where you have work experience
Key evidence	Coursework grades, thesis/project quality, research contributions, classroom engagement	Project outcomes, team contributions, quantified results, leadership moments
Tone	Academic, intellectual, research-oriented	Professional, performance-driven, outcome-focused
When to use	Always required for MS/PhD – typically 1-2 academic LORs	Required for MBA almost always – helpful for MS if you have relevant work experience

Most MS programs require 2 academic LORs and allow 1 professional. MBA programs typically require 2 professional LORs and may ask for 1 academic. Always check each program’s specific LOR requirements before approaching recommenders.

Who Should Write Your LOR?

Choosing the right recommender is as important as the content of the letter. The wrong choice – even from a prestigious name – can hurt your application.

Best choices	Why they work	Avoid
Professor who taught a core course in your major	Subject knowledge directly relevant to your application, can speak to academic depth	Professor who gave you a high grade but barely knows you
Research supervisor or thesis guide	Knows your independent work, analytical ability, and intellectual approach	HOD or Dean who knows you only administratively
Internship or job manager (professional LOR)	Directly observed your work, can cite specific projects and outcomes with numbers	A colleague or peer – perceived as less authoritative
Lab supervisor or project guide	Can speak to hands-on skills and technical contributions	Family members or friends – never accepted as objective
Senior professional you worked with significantly	Can provide context about your professional environment and specific contributions	Anyone who needs you to write the entire letter without input

The single most important criterion: choose someone who genuinely knows your work and can write specific, detailed examples – not just someone with an impressive title.

LOR Format for Study Abroad – Section by Section

A strong LOR follows a clear six-part structure. Here is exactly what each section should cover:

Section	What to Include	Length
1. Header	Recommender’s name, designation, organization, official email, and date. On official company or university letterhead if possible.	4-5 lines
2. Salutation	“Dear Admissions Committee” or “To the Admissions Committee of [Program Name]”. Formal, not casual.	1 line
3. Introduction	Who the recommender is, their relationship with the applicant, how long they have known them and in what capacity. Must establish credibility immediately.	60-80 words
4. Body – Strengths and Examples	The most important section. Specific examples of the applicant’s abilities, contributions, and outcomes. Use numbers wherever possible. Cover 2-3 key qualities with evidence, not a generic list of virtues.	200-250 words
5. Program Fit and Recommendation	Connect the applicant’s strengths to the specific program they are applying to. State clearly that you recommend them without reservation.	60-80 words
6. Closing	Offer to provide additional information. Recommender’s signature, name, designation, and official contact.	30-40 words

How to Write a Strong LOR – Step by Step

Most students share a draft with their recommender. Here is the process that works:

Choose your recommender at least 6-8 weeks before the deadline. Professors and managers are busy. A rushed recommender writes a generic letter. A recommender with time writes a specific, compelling one.
Approach them personally – email or in person. Explain the program, the deadline, and why you are asking them specifically. Share your SOP or resume so they have context about what you are applying for.
Give them a brief document: your key projects or achievements they witnessed, the program requirements, and 2-3 qualities you would like highlighted. Do not write the letter for them – but make their job easier.
If your recommender asks you to draft a letter, do so – but write it from their perspective. Use their tone, reference your work from their vantage point, and include only things they genuinely witnessed.
Remind them once, politely, a week before the deadline. Most recommenders appreciate a gentle nudge – not as a sign of distrust, but as a practical scheduling aid.
After the letter is submitted, send a thank you. If you receive an offer, tell them. Recommenders appreciate knowing the outcome of their effort.

Dear Admissions Committee,

It is with genuine enthusiasm that I recommend Arjun Mehta for admission to your MS in Data Science program. I have been Arjun’s direct manager at Infosys for the past 22 months, during which he has worked as a Data Analyst on our retail analytics team. In that time, I have observed him in high-pressure project environments, cross-functional collaborations, and independent research assignments – and I can say without reservation that he is among the most technically capable and intellectually driven analysts I have managed in over a decade.

Arjun’s most significant contribution during his time at Infosys was rebuilding our customer churn prediction model. The existing model was producing 68% accuracy on our telecom client’s dataset. Arjun independently identified that the feature engineering process was not capturing recency of service interactions – a gap that had gone unnoticed for two years. He redesigned the pipeline using Python and XGBoost, and tested multiple feature sets over six weeks. The final model achieved 84% accuracy and has since been deployed into production, reducing our client’s churn intervention costs by approximately 19%. This project was completed outside his regular responsibilities, and he drove it from problem identification to deployment entirely on his own initiative.

Beyond his technical skills, Arjun brings a quality that is harder to teach: he asks the right questions. In team meetings, he consistently pushes back on assumptions – respectfully and with evidence – in a way that has improved the quality of our outputs significantly. He is also a generous colleague who has mentored two junior analysts on data visualization tools, improving their delivery times measurably. These qualities – intellectual curiosity, initiative, and collaborative generosity – are exactly what research-intensive programs reward.

I am confident that Arjun will bring the same rigor and drive to your MS program that he has demonstrated here. I recommend him without reservation and am happy to provide additional details about his work at Infosys if useful.

Sincerely,
Priya Krishnamurthy
Senior Manager, Analytics

Sample Academic LOR – Professor for MS in Computer Science Application

[SAMPLE – Academic LOR, Professor to MS in CS Admissions Committee]

Dr. Raghav Srinivasan
Associate Professor, Department of Computer Science
NIT Trichy

10 June 2026

Dear Admissions Committee,

I write to strongly recommend Kavya Iyer for admission to your MS in Computer Science program. I have known Kavya for three years as her professor in Advanced Algorithms and Database Systems, and as the guide for her final year thesis on distributed caching mechanisms for high-frequency trading systems. She is one of the most technically capable students I have supervised in my fifteen years at this institution.

In Advanced Algorithms, Kavya’s final examination was the second-highest in a cohort of 120 students. But what distinguished her more than her score was her curiosity beyond the syllabus. She approached me after class to discuss the practical limitations of the algorithm approximation methods we covered – a level of intellectual engagement that is rare in undergraduate students. When I invited her to work on a supplementary research problem about cache eviction policies, she produced a comparative analysis in three weeks that demonstrated genuine independent research capability.

Her thesis work confirmed this potential. Working on distributed caching with consistency guarantees, Kavya navigated a technically complex problem with minimal guidance. She independently reviewed 12 papers on the RAFT and Paxos consensus protocols, designed her own experimental framework, and produced results that compared favorably to published benchmarks. The thesis received the department’s best undergraduate research award for 2025-26.

I am confident that Kavya has the intellectual capacity and research drive to excel in your MS program. I recommend her with full confidence and am available for further discussion if useful.

Sincerely,
Dr. Raghav Srinivasan
Associate Professor, CSE Department
NIT Trichy
