Princeton’s Letters of Recommendation Requirements and Deadlines

Princeton asks for one recommendation from your school counselor and two teacher recommendations.

The counselor recommendation is usually written by someone like your guidance counselor or a school official who knows you well. They’ll talk about your academic growth, your character, and how you’ve contributed to your school. It also gives Princeton some background on what your high school is like—what kind of classes are offered, how tough they are, and how you stack up compared to your classmates.

You’ll also need two teacher recommendations. These should come from teachers who’ve taught you in higher-level classes, like AP, IB, or A-Levels. Make sure they’re from two different core subjects—like math, science, English, social studies, or a foreign language.

Take note of the following deadlines:

• Single-Choice Early Action: November 1
• Regular Decision: January 1

Remember, these letters give Princeton a chance to see the real you—the version that doesn’t always show up in grades or test scores. They help the admissions team understand how you show up in class, how you handle challenges, how you work with others, and the kind of energy you bring to your school or community. At a competitive place like Princeton, where a lot of applicants are strong on paper, that kind of insight really matters.

What Princeton is looking for are letters that feel personal and genuine—not something that sounds like it could be written for just anyone. Strong recommendation letters highlight real qualities, like your curiosity, resilience, leadership, or creativity. They tell a story about who you are and what makes you different, often through specific examples. Instead of repeating your résumé, a great letter adds something new and helps bring your application to life.

Who Should Write Your Princeton Recommendation Letter?

Choosing the right recommenders for your Princeton application is just as important. The university asks for two teacher recommendations and one counselor recommendation.

Two teacher recommendations

The most effective recommendations come from people who truly know you. A teacher who saw you take on a challenge, contribute in class, or grow over time will have a lot more to say than someone who barely remembers your name. Don’t worry about titles. Go for substance.

Look for teachers who:

• Taught you in a core subject, such as English, foreign language, humanities, social sciences, natural sciences, or math
• Had you in junior or senior year, so they can speak to your recent academic performance and growth
• Saw you in action, like when you overcame challenges or lead a group project or took initiative
• Can describe your personal strengths, such as intellectual curiosity, creativity, and grit
• Know you as a person, not just your grades or test scores

If you already know what you want to study at Princeton, it’s smart to ask a teacher from that subject to write your recommendation. So, if you’re applying to the School of Engineering and Applied Science, go with a math or science teacher who’s seen you solve tough problems or think through complex ideas.

Picking someone who understands your academic goals makes it easier for the admissions team to see how ready you are for the path you’re aiming for.

Counselor recommendation

Alongside your teacher recommendations, Princeton also requires a letter from your school counselor. This letter gives the admissions team a broader view of your high school experience, how you’ve grown over the years, your school environment, and how you’ve stood out among your peers.

Your school counselor should be the one to write this letter. If your school doesn’t have an official counselor, someone in a similar role—like a guidance coordinator, academic adviser, or even the principal—can step in.

Quick tip: Take a little time to chat with your counselor so they can add something personal and meaningful to your letter.

Tips for Getting a Strong Recommendation for Princeton

Asking someone to write you a recommendation for Princeton might feel a bit intimidating at first, but it doesn’t have to be. Once you understand what makes a strong letter and how to approach your recommenders, it becomes a lot easier. 

Letters of recommendation aren’t just something to check off your list. Admissions officers at selective schools like Princeton do pay attention to them. In fact, according to a survey by the National Association for College Admission Counseling, about 40% of college admissions officers say recommendation letters are “moderately important” when reviewing applications. 

These letters offer real insight into how you show up in the classroom, how you interact with others, and what kind of student and person you are. So, here’s how to make sure the ones you submit actually add value to your application:

1. Ask ahead of time.

Don’t wait until deadlines are creeping up. Reach out at least a month in advance. Teachers and counselors have busy schedules, especially in application season, and early notice gives them time to write something thoughtful and personal.

2. Go with teachers who really know you.

Choose teachers from core subjects who’ve seen your effort, growth, or unique qualities in class. Even if you didn’t ace their class, a teacher who knows your work ethic or the way you contribute can write something meaningful.

3. Help them help you.

Make things easier for your recommender by giving them a short packet or email with useful details. Include your résumé, a list of activities, a copy of your transcript, and maybe a quick paragraph about why you’re excited to apply to Princeton. That way, they can better connect their letter to your goals and interests.

4. Suggest a few talking points.

It’s totally okay to mention a few things they might focus on—like how you led a group project, stayed engaged in discussions, or bounced back from a challenge. These small prompts can help your recommender add detail that makes your letter stand out.

5. Avoid the “Just Okay” letters.

If someone seems unsure or too busy to write you a strong letter, don’t take it personally—it’s better to ask someone else who’s genuinely enthusiastic about supporting you. A generic letter doesn’t do much for your application.

6. Don’t forget to say thanks.

Once your letters are in, send a thank-you note. It doesn’t have to be long—just sincere. A little appreciation goes a long way, and it’s a great way to close the loop with someone who’s helped you take a big step toward your future.

Princeton Recommendation Letter Request (Email Template)

Not quite sure how to ask your teacher or counselor for a recommendation? Totally normal. A clear and polite message can go a long way, and having a simple structure to follow makes it way easier. Just make sure to personalize your note so it feels genuine and specific to your experience.

When you’re reaching out, don’t be shy about sharing why you chose them specifically. Maybe they saw your progress, how you contributed to the class, or how you handled a challenge.

That little bit of guidance can make their job easier and help you get a more powerful, personal letter.
