Letters of Recommendation: Who to Ask and How
Who should write your recommendation letters, when to ask, what to give your recommenders, and how U.S. admission readers actually use them.
Recommendation letters are the only part of the application written by someone with no obligation to flatter you. Readers use them for context the transcript cannot give: how you behave in a room, how you respond to difficulty, and whether the numbers on the file match the person.
Who to ask
Teachers from core academic subjects, preferably from junior or senior year, and preferably from the subject area closest to your intended major. A recent teacher remembers specifics; a teacher from ninth grade remembers a child.
The counselor letter is different in kind. It describes your school, your course load relative to what was available, and any circumstances that shaped your record. It is institutional context rather than personal testimony.
Supplemental letters — from a research supervisor, employer, coach or community leader — are accepted by some universities and help only when the writer can describe something no teacher could. One well-chosen additional letter is worth more than three generic ones.
The best recommender is not the most senior person who knows your name. It is the person who can describe a specific afternoon in which you did something notable.
When to ask
Ask in person, in the spring of junior year or at the very start of senior year, and follow up in writing. Recommenders write dozens of letters each autumn, and the ones written in October are better than the ones written on 30 December.
Give at least four weeks before the earliest deadline. For Early Action and Early Decision, that means asking in September at the latest.
How to ask
Ask a question rather than issuing a request: "Do you feel you know my work well enough to write a strong letter of recommendation?" This gives a teacher who cannot write a strong one a graceful way to say so, which is a gift — a lukewarm letter does real damage.
Then supply a short packet:
- A résumé or activity list
- Your transcript
- The list of universities and their deadlines, with submission instructions
- A paragraph on what you hope to study and why
- Two or three specific moments from their class you remember: a project, a question, a turning point
That last item is the one most students skip and the one that produces the best letters. Teachers are not trying to write vaguely; they simply do not have the details in front of them.
Submission mechanics
Letters are almost always submitted electronically. On the Common Application you invite recommenders through the Recommenders and FERPA section, after which each receives a link. You must complete the FERPA release before invitations can be sent, and you should waive your right of access.
Track submission status in the portal. If a letter is missing a week before the deadline, send a polite reminder. Universities are used to late letters and rarely penalise the applicant, but the file will not be read until it is complete.
After the deadline
Write a thank-you note. Tell each recommender where you were admitted and where you decided to enrol. They wrote for free, on their own evenings, and hearing the outcome is the only return they get.
Frequently asked questions
How many recommendation letters do I need?
Selective private universities typically ask for one counselor letter and two teacher letters. Most public universities require none at all. Sending more than requested rarely helps and sometimes annoys the reader.
Should I waive my right to see the letter?
Yes. Waiving access under FERPA signals to the reader that the letter was written candidly, and most recommenders expect it. A non-waived letter is discounted.
Can I ask a teacher who gave me a B?
Often that is the better choice. A teacher who watched you struggle with hard material and improve can write something far more specific than one who watched you coast to an A.
What if my school does not assign counselors?
Any school official who can verify your record and context works: a principal, a head of year, a programme coordinator. Explain the situation in the additional information section.
