Letter of Recommendation for Graduate School – Guide and How to Request It

Time to read: 5 Minutes

Letters of recommendation are a critical part of a graduate’s school application. A student should be cautious when deciding whom to contact for a recommendation letter.

Letter of Recommendation – In a Nutshell

  • A letter of recommendation is a referral that speaks well of a student’s character and qualifications.
  • A university or college student should get a letter of recommendation from supervisors or professors they have worked with outside a classroom environment.
  • The recommender should be well-versed in the student’s capabilities.

Definition: Letter of recommendation

A recommendation letter is written by an academic or professional supervisor vouching for the applicant’s good character.1 A student should ask for a recommendation letter if they are considered for a certain educational program.

Letter of recommendation: Whom to ask

The most fundamental process of asking for a recommendation letter is deciding who will write it. The best person to write a letter of recommendation is someone the student has worked with away from the class environment—for example, a former supervisor.

An admissions committee wants someone that can vouch for the student’s ability to perform well in the program. The recommender should, therefore, know the student well.

Before choosing a recommender, the student must consider the qualities that align with their specific program.

Research programs, including MPhil, DPhil, Ph.D., and Research Master’s, want to admit a student that has demonstrated their passion for research.2 Such qualities can barely be verified using academic documents.

The letter of recommendation plays a huge role in the admission of students to a graduate research program.


  • A student who wants to join a research program should get a letter of recommendation from someone who can vouch for their research skills.
  • They should get if from a professor they worked with during an autonomous research test.
  • Also, they could get it from the lab supervisor the student worked with during their undergraduate program.
  • Another option for a student that wants to join a research program is to ask for a letter of recommendation from their work supervisor—if they worked as a lab assistant or a researcher.
  • The student could also ask the managers in their previous job, who are researchers, since they understand the qualities required for a good researcher.

Letter of recommendation: Request a meeting

The second step is to request a meeting with the recommender. A student can request an appointment with a supervisor they last talked to a long time ago.

Their email should include a quick reminder of the student’s interaction with their potential recommender and it should reflect a balance between friendliness and directness.

The ideal option for the student is to arrange a meeting with the recommender in person.3 However, this may not be practical due to distance or other factors. In this situation, a simple email should suffice.


Ask for the letter of recommendation

A student should request a recommendation letter in an email or in-person meeting with the recommender. For this, the student should follow these guidelines:

  • Discuss the programs they hope to pursue and their deadlines with the recommender
  • During this process, they need to give the recommender adequate time.
  • They should seek a good offer when asking for a recommendation.
  • A letter of recommendation should be positive rather than neutral to help a student’s application.
  • If the preferred recommender cannot give a strong recommendation, the student should look for a new person for a positive recommendation.
  • The student should attach documents such as their resume, statement of purpose, writing samples, or personal statement in their email requesting a letter of recommendation.

Different programs may have specific tips that the recommenders should follow. In the case of research programs, the recommender should include any publications or projects the students have completed.

Letter of recommendation: Send a reminder

A student should email the recommender a few weeks before the deadline to remind them of the letter of recommendation. They should only send a few emails as the recommenders may be busy.

Example of an email reminder:

Dear Supervisor Alfred,

I hope you had a great week. Thank you for agreeing to write my letter of recommendation. I am writing to remind you that my letter of recommendation for Research Program Q is due in two weeks, on 10th January.
Kindly inform me if you need any other documents from me, and thank you again.

Best Regards,


A letter of recommendation shows that the writer believes the student has the skills and ability to join a program.

A former supervisor or professor.

Yes, if the recommender is available and willing to meet.

Yes, a student can take a recommendation from a non-professor—if the recommender is an expert in a particular field.
