How to Ask a Teacher for a Recommendation Letter
The A, or the teacher who knows you
It is late April, and Leo, a junior, is about to email his chemistry teacher. He earned an A in her class, so asking her feels like the obvious choice. But Leo sat near the back all year, rarely spoke, and has never talked with her outside class.
His history teacher gave him a B+. She also watched him get a weak grade on his first research paper, come to her after school to understand why, and rewrite his next one from the ground up. Later in the year she saw him organize the class's mock trial and coach two classmates who were nervous about speaking. If each teacher were asked to describe Leo in a page, only one of them would have something real to say.
Why these letters matter
Almost everything else in an application is written by the student. A teacher letter is one of the few places where an adult who has watched the student up close describes them in their own words. Readers use it to see how the student learns, how they treat others, and whether the person in the essays is the same person who shows up in class.
MIT puts it plainly: "the best recommendations are written by teachers who know an applicant well as both a student and a person." A short letter full of specific moments does more than a long letter full of general praise.
How many letters colleges ask for
It varies, so check each college on the list. Some examples:
- Stanford asks for letters from two academic teachers, plus a letter from the school counselor.
- MIT asks for two teachers: one in math or science, and one in the humanities, social science or a language. It also allows one optional extra recommender.
- Many colleges ask for one or two teacher letters, and some do not ask for any.
The counselor letter is separate. It comes from the school counselor, who writes about the student in the context of the whole school. Students do not choose a teacher for it, but it helps to meet the counselor during junior year so the letter is not written about a stranger.
Who to ask
Think of the two letters as two different views of the same student.
The teacher who knows how you think. A teacher from a core academic subject (English, math, science, social studies or a language), ideally from 11th grade, because that teacher has seen the student at their most recent and most demanding level. If the student has a clear direction, this letter should come from that area when possible. A future engineer is usually best served by a math or physics teacher; a future journalist, by an English or history teacher.
The teacher who knows who you are. A teacher who has seen the student outside the routine of tests and homework: leading a group, helping a classmate, handling a setback, or making the class better in a way the teacher noticed. Many colleges require both letters to come from academic teachers, so for most students this is an academic teacher who has also seen them in another setting, such as the adviser of a club they lead. Where a college accepts an optional extra letter, a coach, director or employer who knows the student well can fill that role.
Choose by how well they know you, not by the grade. A teacher who gave a B and watched the student grow can write a far stronger letter than one who gave an A and barely knows them. A simple test: could this teacher tell a story about you without looking at your grades? If not, look further.
When to ask
Ask in the spring of junior year, before summer break. Many teachers write most of their letters over the summer or early in the fall, and some limit how many letters they will write each year, so students who ask early get the time and attention they need. Asking in person first, then confirming by email, is the most natural way to do it. Applying through Early Decision or Early Action makes asking early even more important, because those deadlines usually fall in November.
What to give your teacher
A teacher cannot write a specific letter from memory alone, especially when they have taught a hundred students that year. The student's job is not to write the letter, but to hand the teacher the raw material. Four things help most:
- Two or three specific moments from their class. Stories, not achievements. A question that changed a discussion, a project where the student took on the hardest part, a time they struggled and worked their way through it.
- A one-page summary of the student's classes, activities, jobs and responsibilities, so the teacher can add context.
- The story the application is telling, in one or two plain sentences. The teacher should not repeat it, but knowing it lets the letter support it from a different angle.
- The colleges and their deadlines, earliest first, and how the request will arrive (usually an email from the Common App or a college's own portal).
The line to hold: give the teacher evidence, not phrases to copy. Describe what happened and let the teacher decide what it shows. If the student mentions qualities at all, they should offer them gently, as something the teacher can use only if it matches their own experience.
Following up
About three weeks before the first deadline, send each teacher a short, friendly reminder with the date, and offer to resend the request or answer any questions. This is normal and expected. Teachers are writing many letters at the same time, and most appreciate the nudge.
After the letters are in
When the applications are submitted, send each teacher a real thank-you note, handwritten if possible. In the spring, let them know where you were admitted and where you decided to go. Teachers rarely hear how the story ends, and they remember the students who tell them.
Two practical details along the way. The Common App asks students whether they waive their right to see their letters later; most counselors recommend waiving it, because colleges tend to trust letters the student will not read. And the student never submits the letter themselves: the teacher uploads it directly.
Pursiva's recommendation
- Ask two academic teachers who know you well,one who has seen how you think and one who has seen who you are, and check each college's rules before deciding.
- Choose by how well the teacher knows you,not by the grade they gave you.
- Ask in the spring of junior year,in person first, then by email.
- Send a short packet of specific moments,with your one-page summary, your theme and your deadlines.
- Give evidence, not the letterLet the teacher draw their own conclusions.
- Send a reminder three weeks before the first deadline, and a thank-you note at the end
Five mistakes to avoid
- Choosing the teacher who gave the highest gradeA letter is only as strong as the teacher's knowledge of the student.
- Waiting until senior fallThe teacher may already have more letters than they can write well.
- Sending only a resumeIt lists what the student did, but gives the teacher no stories to tell.
- Writing the letter for the teacherReady-made phrases make the letter sound like the student, and readers notice.
- Disappearing after the requestNo reminder, no thank-you, and no news in the spring.
How Pursiva helps
Pursiva's Recommendations module supports the student through the whole process. It helps them decide whom to ask by looking at which classes and teachers have seen them grow, lead or take on something hard. It gives examples of how to ask a teacher for a letter, what to send with the request and how to follow up, which the student adapts in their own words. When it is time to prepare the materials, it asks questions that help the student recall specific moments from each class and see how those moments connect to the theme of their application (Pursiva calls it a Core Narrative). And it keeps the colleges, deadlines and reminder dates in the plan, so nothing is left to the last week.
Leo asked his history teacher. Her letter described the student who came back after a C+, and that was the student Leo wanted colleges to meet.
