How to Ask for Letters of Recommendation (and Get Great Ones)

Letters of recommendation are one of the most overlooked parts of the college application. A strong, specific letter from a teacher who knows you well can meaningfully lift your application, while a generic letter — even a positive one — does little. The good news is that getting great letters is largely within your control.

This guide covers who to ask, when to ask, and how to make it easy for your recommenders to write you something genuinely strong.

Who to Ask

Choose teachers who know you well and can speak specifically about your work, your thinking, and your character — not just the teachers whose classes you got the highest grades in. A junior-year teacher in a core academic subject (English, math, science, history, or a foreign language) is usually ideal, because they taught you recently and in a substantive course.

Many selective schools ask for recommendations from teachers in different subject areas, so a humanities and a STEM teacher together often work well. If you intend to study a particular field, a letter from a teacher in that area can reinforce your direction. The most important factor is not the subject but how well the teacher knows you and how specifically they can write about you.

When to Ask

Ask early — ideally in the spring of junior year, before teachers are inundated with requests in the fall. Teachers write many letters, and the best ones take time. Asking early shows respect for their time and gives them room to write something thoughtful rather than rushed.

If you miss the spring window, ask as early as possible in the fall of senior year, well before your deadlines. Always give recommenders at least several weeks, and more if you can. Never ask a teacher to write a letter on short notice for an imminent deadline.

How to Ask

Ask in person when possible, and ask sincerely: explain why you are asking that particular teacher and what their class meant to you. A genuine, specific request is both respectful and more likely to produce a strong letter. Make it easy for them to say yes — and easy for them to decline gracefully if they cannot write a strong letter, since a lukewarm letter helps no one.

Once they agree, provide everything they need: your deadlines, the submission process (most letters go through the Common App or school system), and any relevant context about your goals and the schools you are applying to.

The Brag Sheet: Make It Easy to Write About You

Give each recommender a 'brag sheet' — a short document that reminds them of your accomplishments in their class, your broader activities and goals, and specific moments or projects they might reference. This is not bragging; it is helping a busy teacher write a specific, detailed letter instead of a generic one.

A good brag sheet includes a few specific anecdotes (a project you were proud of, a question you pursued, a moment of growth), your intended area of study, and what you hope the letter conveys. The more concrete material you provide, the more specific and compelling the letter can be.

The Counselor Letter, Following Up, and Saying Thank You

Most applications also require a letter from your school counselor, who writes about you in the context of your school and class. Even if your counselor has a large caseload, you can help them by sharing your brag sheet and meeting with them so they know who you are. This matters especially at large schools where counselors handle hundreds of students.

As deadlines approach, follow up politely to confirm letters are submitted, and always thank your recommenders — a sincere note after they submit, and an update when you hear back from schools. They invested real effort in your future; acknowledging it is both gracious and good practice.
