How to Ask for a Grad School Letter of Recommendation

How to Ask for a Grad School Letter of Recommendation

Ask by email at least a month before your earliest deadline, ask whether they can write a strong letter, and attach a packet: CV, SOP draft, program list with deadlines, and a summary of the work they saw. Enter them in each portal only after they say yes.

Much of the advice on the ask is etiquette. The more useful fact is what your recommender will be asked to do. Stanford's graduate recommendation form, for example, asks each writer to pick a comparison group, say how many people are in it and place you in a percentile from "Top 1-2%" down. An email that only says "would you write me a letter?" leaves them to rebuild that judgment from memory. This page builds the ask around those questions, with four constructed email templates and a reminder. If you need the full letter process first (how many letters, who to choose, portals and the confidentiality waiver), read our grad school letters of recommendation guide.

Every program page quoted below was checked on October 30, 2026. The two faculty advice pages are dated by their authors (2002 and 2014) and are cited as one professor's view each.

What your recommender will be asked

Stanford Graduate Admissions publishes its whole form. Each recommender is asked to respond to:

Please identify the most selective group to which you are comparing the applicant

How many years have you evaluated people in this group?

Approximately how many people are in this group, totaled over those years?

In overall ability (as appropriate to graduate studies) this candidate is among the:

The ranking choices run "Top 1-2%", "Top 5%", "Top 10%", "Top 25%", "Second quarter", "Third quarter", "Bottom quarter" and "No basis for judgment". The form then asks for a recommendation from "Strongly recommended" to "NOT recommended", and a letter. The general letter prompt asks the writer to "write candidly about the applicant’s qualifications, potential to carry on advanced study in the field specified, intellectual independence, capability for analytical thinking, ability to organize and express ideas clearly, and potential for teaching." Stanford adds: "The exact prompt displayed to the recommender may differ depending on the graduate program you select."

Other programs say what they want from writers in their own words:

Our view: the ask email's job is to make that ranking easy to fill in honestly. Give the writer the comparison facts (which course or project, when, how many students or colleagues they saw you alongside), the evidence for each quality the form names, and the deadline list. A writer who has to reconstruct those facts may default to a vague letter or a cautious rating.

The countercase: a PI who supervised you for two years does not need a dossier. Send them the short version: the program list, deadlines and your SOP draft. Over-briefing a writer who knows your work can read as scripting their letter.

The packet: what to attach and why

Michael Ernst, a University of Washington computer science professor, wrote his request advice in October 2002. Mor Harchol-Balter's Applying to Ph.D. Programs in Computer Science was last updated in 2014 and describes itself as expressing "only the opinions of the author". Both are dated, but the packet advice matches what current forms ask. Harchol-Balter's warning still applies: "Be careful not to make the packet too large." One page per project is enough.

Timing. Ernst: "Give letter-writers a minimum of two weeks, and preferably a month or more, to write letters." Our recommendation: treat a month as the floor and ask earlier for a long program list, because each portal sends the writer a separate request. Berkeley asks you to "Be sure to inform your recommenders of the program’s application deadline."

Four ask-email templates

Four constructed templates, written by us. Replace every bracketed item. Each is under 150 words. Harchol-Balter suggests the core question: "Do you feel comfortable writing a strong letter of recommendation for me to graduate school?" Phrasing it this way gives the writer a polite way to say no.

Constructed template: a professor from a recent course

Constructed template, written by us, not a real email. 124 words.

Subject: Recommendation request: PhD applications, first deadline December 1

Dear Professor [Name],

I took your [course] in [term] and wrote my final paper on [topic], which you supervised in office hours. I am applying to PhD programs in [field] this fall, with deadlines from December 1 to December 15.

Would you feel comfortable writing a strong letter of recommendation for me? I would especially value your view of my analytical writing, which the paper and two problem sets showed most.

If yes, I will send a one-page packet by [date]: my CV, my statement of purpose draft, the program list with deadlines, and a summary of my work in your course. If the timing does not work, I completely understand.

Thank you, [Your name]

Constructed template: a professor you have not seen for years

Constructed template, written by us, not a real email. 132 words.

Subject: Former student asking about a recommendation for a master's program

Dear Professor [Name],

I was in your [course] in [year] and worked with you on [project]. Since graduating I have worked as [role] at [employer], where [one concrete thing related to the field].

I am applying to master's programs in [field] for fall 2027, with deadlines in January. Would you feel comfortable writing a strong letter based on my work in your course? I know it has been some time, so I have attached my old paper, my grade and a short update on what I have done since.

If you would prefer not to, or feel you cannot speak to my current work, I understand. A short call is also fine if that would be easier.

Best regards, [Your name]

Ernst's page covers this case directly: "If you have not been in recent contact with the letter writer, you should provide an update on what you have been up to recently." He also suggests that, in that case, you consider getting letters from people who know you better.

Constructed template: a manager or work supervisor

Constructed template, written by us, not a real email. 114 words.

Subject: Request: recommendation for my master's application

Hi [Name],

I am applying to master's programs in [field], starting fall 2027. Each asks for [number] letters, and you have supervised more of my work than anyone.

Would you be comfortable writing a strong letter? The programs ask recommenders about [quality from the program's page, e.g. collaboration and handling setbacks]. The [project] we shipped in [quarter] is the clearest example I can think of.

If yes, I will send a short packet with my résumé, statement of purpose draft, the program list and deadlines, and a summary of that project. Each school will email you a separate upload link.

Thank you for considering it, [Your name]

Subject: PhD applications: letter request and program list

Dear Dr. [Name],

I have decided to apply to PhD programs in [field] this cycle. My list is attached, with eleven programs and deadlines between December 1 and December 15.

Would you be willing to write a strong letter for me? I have attached my CV and statement of purpose draft so the two can tell the same story about the [project] work. If it helps, I can also send a one-page summary of what I did on the project and when.

Could we talk for ten minutes this week about which programs fit best?

Thank you, [Your name]

After they say yes: portals, timing, reminders

Register each writer in each portal as soon as they agree. Stanford explains the mechanics: "After you enter your recommender’s information, the application system sends a personalized link to that individual to submit the recommendation online." You can manage writers afterwards: "This includes sending reminder emails and changing recommenders."

Read each program's rules on timing and delivery. Three examples, checked October 30, 2026:

• CMU MHCI accepts letters after you submit: "Your recommenders can upload a letter after you have submitted your application up until the 3:00 p.m. EST deadline." It does not accept mailed letters: "Letters received by post will not be considered with a student's application."
• MIT Economics requires letters by the application deadline: "Letters must be submitted/uploaded by the letter writers by December 15." (MIT Economics; December 15, 2026 is a Tuesday.)
• UCLA Sociology warns about letter services: "Use of Interfolio to submit letters of recommendation is not recommended, as rating data may not transmit correctly through the system." (UCLA Sociology) Our guide to Interfolio and graduate rating forms covers the workaround.

Constructed template: the two-week reminder

Constructed template, written by us, not a real email. 67 words.

Subject: Reminder: first recommendation due December 1

Dear Professor [Name],

Thank you again for agreeing to write for me. A quick reminder that the first deadline is December 1. The portals show letters received for [programs] so far; [programs] are still open. Each school sent its own link, and I can resend any that are missing.

The full list with deadlines is below.

Thank you, [Your name]

Harchol-Balter also suggests giving writers a date earlier than the real deadline. Use that only if you can still meet the real one if they are late.

Reading the reply

• A clear yes with a question about your work is the best sign. Send the packet the same day.
• A hedge ("I could write you a letter, but I didn't see much of your research") is a signal to line up another writer.
• A no is useful information. Thank them and move on. Harchol-Balter, on a writer who declines: "This is much better than getting a weak letter."

Do not drop an obvious writer to avoid an awkward ask. Ernst: "Don't omit obvious people such as past supervisors and advisors from your list". He also says "it's better to have 3 very strong letters than to have 4 letters, only 3 of which are very strong." UCLA Sociology allows more than three letters, "but note that quantity does not substitute for quality."

If you are asked to draft it yourself

Some writers ask the applicant for a first draft. Some programs prohibit it. Stanford's rule, quoted in full: "Your recommenders must be the sole authors of your letters of recommendation. Drafting, writing, translating, or submitting your own reference, even if asked to do so by a recommender, is a violation of our application terms. You are responsible for informing your recommenders of this policy."

UC Berkeley's Graduate Division states: "The Graduate Division may verify the authenticity of academic letters of recommendation with the school or recommender."

Read each program's rule before you respond to that request. Our guide on being asked to write your own letter of recommendation covers the options. GradPilot's letter reviews aren't for a letter you drafted for a recommender to submit as their own.

Questions about asking for grad school recommendation letters

How far in advance should I ask for a letter of recommendation for grad school?

At least a month before your earliest deadline. Ernst's minimum is two weeks, "and preferably a month or more". Earlier is better when you have many programs, because each portal sends its own request.

Should I ask by email or in person?

Either works. Email gives the writer something to refer back to, so send one even after an in-person conversation, with the packet attached or promised by a date.

How many people should I ask?

Ask for the number each program requires. Every program on this page that states a number asks for three, including Stanford. UCLA Sociology accepts more but says "quantity does not substitute for quality". Having one more willing writer in reserve protects you if someone goes silent.

Can I ask a TA or graduate student for a letter?

Check the program's page first. Stanford wants "academic or professional references who know you well" and strongly recommends at least one professor. Harchol-Balter's view is blunt: "Please do not get a letter from a graduate student." She suggests asking the professor they work for to co-write the letter instead.

Should I thank my recommenders, and how?

Yes, and tell them the outcome. Ernst: "tell your letter-writers the outcome." On gifts the two professors disagree. Ernst: "Don't give gifts. It is not appropriate." Harchol-Balter suggests "a thank you card (or chocolate!)". A written thank-you note works under both. If a letter still shows as missing after your deadline, here is how to email grad admissions after applying without sending a status check.

Get a free review of your statement of purpose

The SOP draft is the one packet document you write, and your writers will read it before they write. Get a free Quick Review of your statement of purpose against GradPilot's MS statement of purpose rubric before you send it. It reads for clear academic interests, preparation and goals, and whether your experiences support your plans. Applying to PhD programs? Use the PhD statement of purpose rubric. If your recommender wants a second read of the letter they are writing, the graduate recommendation letter rubric is built for the writer, and the recommendation letter review page explains it.

• LOR format and sample for MS and PhD recommenders: send this to a writer who asks what a graduate letter looks like.
• PhD letters of recommendation: what committees want: how to choose your three writers.
