Knowing how to ask for a letter of recommendation comes down to three things: ask the right person, ask early enough, and hand over everything they need in one place. The letter is a part of your application that someone else writes. What you control is the request: who gets it, when it arrives, and what comes with it.
Key Takeaways
- Ask before you add anyone to an application. Common App says asking in person is best, though email is fine.
- Common App’s suggested minimum is three weeks before a deadline. Other offices ask for more: 30 days at Bellaire High School in Houston, five to six weeks at Union College’s career center.
- Applying to college? Common App’s 11th-grade guide says to line up recommenders in the spring of junior year.
- After someone says yes, send one email with your resume, your deadlines, how the letter is submitted, and what you hope they can speak to.
Who to Ask for a Letter of Recommendation
Start with what the application asks for, then choose the person. Many colleges ask for letters, and Common App’s first-year application guide says every college “gets to choose their own recommendation requirements.” Before you approach anyone, check each college’s information page for how many letters it wants and from whom.
Then pick people who know your work well. Common App’s recommender types are counselors, teachers, advisors (who submit no forms) and other recommenders, which its guide describes as “usually non academic recommenders like coaches, employers, and peers.” Union College’s Becker Career Center, writing about graduate school and job letters, says to choose professors or supervisors “who know you well and can speak to your capabilities.”
Graduate, law and MBA programs set letter rules of their own, and asking a professor for a graduate school letter comes with its own etiquette. Medical school letters differ again, so who to ask for medical school letters is a separate decision.
When to Ask for Letters of Recommendation
No single rule covers every application, and the sources that publish a lead time do not agree. Here is who says what, as of October 2026.
| Source | Who it covers | How far ahead to ask |
|---|---|---|
| Common App, "Understanding the Recommendation Process" (revised July 2025) | Common App first-year applicants | At least three weeks before a deadline |
| Common App, 11th-grade planning guide | High school juniors | Spring of 11th grade, to line up one or two teachers |
| Bellaire High School counseling office, Houston | Its students' teacher and counselor letters | 30 days' notice |
| Union College, Becker Career Center | Graduate school and job applications | At least five to six weeks before the due date |
Common App’s recommendation guide says to ask “at least three weeks in advance of a deadline.” That is Common App’s figure for its own applicants, and some offices set a longer one.
When a longer rule applies to you, it is the one that counts. Bellaire High School in Houston tells students to ask teachers and counselors in person, with 30 days’ notice. Its counselors will not process a Common App request until the student has visited and submitted a brag sheet.
Union College’s Becker Career Center asks for at least five to six weeks before the due date, “so they have plenty of time to complete it.”
When College Applicants Should Ask
For college applicants, Common App’s guides, read together, point to two moments. Its 11th-grade planning guide says “Don’t wait until senior year to secure your recommenders” and suggests asking one or two teachers in the spring of junior year. The formal request, with your materials, follows in senior year, at least three weeks before each deadline. Count back from your earliest one, including any early action or early decision date.
If Your Deadline Is Less Than Three Weeks Away
Ask anyway, and put the date in your first sentence so the person can judge whether they have time. Some colleges also give letters more room than the application itself:
- MIT says you do not have to wait for your recommenders before you submit, and that recommender materials arriving after the deadline “are still accepted and attached to your application.”
- Cornell wants Early Decision applications by November 1 and “All other required materials” by November 13, for fall 2027 entry.
Check each college’s own page before you count on extra time.
How to Ask for a Letter of Recommendation: In Person or by Email
Ask the question before you enter anyone’s name in an application. Common App’s recommendation guide says to confirm a recommender is willing before you invite them, and it puts the format plainly: “It’s best to ask in person, but an email is ok too.”
If you can, ask in person, at a time that suits them. Union College’s career center suggests scheduling a time to ask whether they are willing to write a positive letter. That phrasing gives them room to decline, and a decline now leaves you time to ask someone else.
Keep the ask short: what you are applying to, your earliest deadline, and why you chose them. If you ask in person, send a short email the same day so the details are in writing.
What to Send Your Recommender
Once someone says yes, send everything in one email. Common App’s guides and Union College’s list overlap on most of it:
- Your resume. Common App’s guide for transfer applicants suggests “a copy of your current resume or written examples of experiences you have had with them.” Union lists a resume too, plus a transcript and a personal statement.
- What you hope they can speak to. The same Common App guide says to tell a recommender if there is something about a program you would like highlighted. Union asks for “any qualities or experiences that you want highlighted.”
- Every deadline, earliest first, with the name of each program.
- How the letter is submitted. For an online form, Union’s instruction is that “you provide the link to the online form to your recommender.”
In Common App, the link comes from the system. Assigning a teacher or other recommender to at least one college “generates the invitation email to be sent to the recommender,” according to Common App’s help article on assigning recommenders. So tell your recommender to expect an email from Common App, and check the address you entered.
If your high school uses one of Common App’s partner systems, counselor and teacher invitations go through that system instead.
Common App’s first-year toolkit includes a Counselor Brag Sheet and a Teacher Brag Sheet, questionnaires you fill in so your recommenders have more to draw on.
When you invite recommenders, Common App prompts you to complete a FERPA release, which asks whether you waive your right to review your letters. Common App’s FERPA guide says waiving “lets colleges know that you don’t plan to read your recommendations.” It adds that some recommenders “may only write a letter if you have waived your rights.”
What the letter says is the recommender’s call. If a recommender asks what a strong letter contains, our letter of reference template breaks it into four paragraphs, each with one job.

Email Examples for Asking for a Letter of Recommendation
The three emails below are ours, written for this article. No school or application system publishes them, so change every bracket and put them in your own words.
Example 1: Asking by Email
Use this when you cannot ask in person.
Subject: Letter of recommendation request, [program], due [date]
Dear [title and last name],
I am applying to [program or colleges] [this fall], and my earliest deadline is [date]. Your [class, team, job or project] mattered a great deal to me, especially [one specific moment]. Would you be willing to write a letter of recommendation for me? If your schedule is too full, I understand completely.
If you can, I will send my resume, my deadlines and the submission details in one email.
Thank you,
[Your full name]
Example 2: Sending the Details After a Yes
Subject: Details for my letter of recommendation
Dear [title and last name],
Thank you for agreeing to write for me. Everything is below, and my resume is attached.
– Programs and deadlines: [program, date]; [program, date] – How to submit: [an invitation email from Common App / the link below / the attached form] – What I hope you can speak to: [one or two specific experiences with you] – Also attached: [a draft of my personal statement]
Please tell me if anything else would help.
Best,
[Your full name]
Example 3: A Reminder Before the Due Date
Union College’s career center suggests a reminder if a letter is not done two weeks before it is due. Check the status first, since Common App lets you track each recommendation inside your application.
Subject: Reminder: letter of recommendation due [date]
Dear [title and last name],
A short reminder that my first letter is due on [date]. [The invitation came from Common App on (date). / The link is below again.] Thank you again for your help.
Best,
[Your full name]
After the Letter Is In
Common App’s guide says it directly: “Don’t forget to thank your recommenders.” Union College adds one more step. Tell them how it turned out, because “they will want to know!”
Your recommender writes the letter from what they remember and what you hand them. That packet is the part you can still shape: the resume, the examples you name, the dates. If you want an advisor to look over it, or the rest of your file, book a free consultation this application cycle.
Frequently Asked Questions
Is it okay to ask for a letter of recommendation via email?
Yes. Common App’s own guide says asking in person is best but email is fine. Email is a fair choice when the person knows you, if your message names the program, your earliest deadline and why you chose them. After an in-person ask, follow up by email the same day.
How far in advance should you ask for a letter of recommendation?
At least three weeks before your earliest deadline by Common App’s count, and five to six weeks by Union College’s career center. For a November 1 deadline, that means asking by October 11 under Common App’s guidance, or by September 20 to 27 under Union’s. Your school may set its own minimum.
Is it too late to ask for a letter of recommendation?
Not necessarily. Under three weeks is below Common App’s suggested minimum, so ask now, name the date in your first sentence, and send your materials the same day. If they decline, thank them and ask someone else. Some colleges take recommender materials late; MIT says materials arriving after its deadline are still attached.
What should you send when asking for a letter of recommendation?
One email with four things: your resume, each program and deadline in date order, how the letter is submitted, and one or two experiences you hope they mention. Some schools want more; Bellaire High School asks students to email a brag sheet along with their resume. Attach a draft personal statement if you have one.
