Quick answer: Send an additional recommendation letter only when the college accepts one and the writer offers a new perspective, such as a coach, employer, research mentor, or arts instructor who knows a side of you your teachers can’t describe. Most admitted students submit only the required letters, so choose an extra recommender carefully.
Should You Ask for an Additional Recommendation Letter?
Your letters of recommendation for college are an integral piece of your application. This part of the process is often overlooked, as it does not require work from your end. But every recommendation letter deserves thoughtful reflection!
Your college recommendations are the only time that admissions officers will hear from an objective third party about who you are. Finding a recommender who will vouch for you is crucial.
When it comes to college recommendations, students often stress about whom to ask. Most colleges ask for one letter from the student’s counselor, and two from their teachers. [1] But what if you feel like these teachers don’t really know you? Or can’t speak to what you’re interested in?
Many colleges allow you to submit one additional recommendation from someone who knows you well, not necessarily another teacher. Yale, for example, notes that an optional recommender should know you well personally or have mentored you closely in some capacity. [2] This additional perspective can shed more light on your character and interests, but only when it adds something new. Read below to learn when an additional recommendation letter makes sense and when the required letters already tell your story.
When an Additional Recommendation Letter Helps
1. You’ve had significant involvement in an activity outside of school:
Many students do remarkable things outside of the classroom, whether it’s a job, research, or a significant volunteer experience. That in itself can be covered in the Common App activities list, but if there is an adult that knows you well personally, academically, and professionally in said activity, then consider asking them for a recommendation letter. If you’re still unsure, consider how MIT describes a useful supplemental recommendation: one that provides different or additional context beyond the two teacher letters it already requests. [3]
2. You don’t know your academic recommenders that well
Most schools are pretty explicit about the main recommenders being high school teachers (MIT, for example, asks for one letter from a math or science teacher and one from a humanities, social science, or language teacher) [3]. However, you might have legitimate reasons to believe that your recommenders might not paint the whole picture of you in their recommendation letter. Maybe you’ve switched schools 4 times throughout your high school career or you attend a school with an average class size of 40 students, with little opportunity to build a rapport with your teachers. Of course, this is a special case as there are steps you can take to start building relationships with your teachers to get a glowing recommendation letter. But if you feel like your teachers cannot speak about you in a personal way, it is worth considering an additional recommendation letter.
3. The school requests or encourages an additional letter:
Some colleges invite a specific kind of extra letter. Dartmouth, for example, encourages a peer recommendation from a teammate, classmate, coworker, or friend, as long as that person isn’t in a supervisory role in your life. [4] Our guide to the peer letter of recommendation explains what it should say. Be sure to do your best to submit materials that a school “highly encourages” or “highly recommends.”
When the Required Letters Are Enough
1. The person is impressive, but doesn’t know you very well:
Remember that the purpose of these letters is for admissions officers to get a sense of you as a person, how you behave in the classroom, and what type of impact you have in your community. A generic letter from the superintendent of your school district, for example, adds little because the writer can’t describe you in detail. A thoughtful letter from someone who sees you regularly, like a coach or mentor, often says far more than a famous name. What matters is how well the writer knows you.
2. The school doesn’t use them or asks you to be selective:
Policies vary widely. Some universities don’t use recommendation letters at all, while UT Austin, for example, accepts up to two optional letters from mentors or people who know you well. [5] Others don’t outright ban extra letters, but want the student to be critical about the additional materials they submit. [2] Yale, for example, notes that most successful applicants submit only the required letters, and that an extra letter should add new information rather than repeat what appears elsewhere. [2] MIT makes a similar point: most applicants and most admitted students don’t submit any supplemental recommendations. [3]
In short, an additional letter helps when the writer knows you well and can share new, detailed information.
3. There’s no new, valuable information to add
Application readers review a large amount of material in a short period of time. Consequently, they’ve become experts in identifying fluff material. Keep your file focused so that every piece adds something new.
When it comes to an additional recommendation letter, one-size-fits-all advice will not apply. Ultimately, you’ll have to make a decision based on your own experiences and the school’s specific requirements.
Who to Ask for an Additional Recommendation Letter
The best additional recommender is someone who has watched you work over time and can describe specific moments, not someone chosen for a title. Think about the adults who have seen you take on responsibility, recover from a mistake, or grow in a skill over months or years. Good options include:
- A research mentor or lab supervisor who can describe how you approach problems and handle setbacks.
- A coach who has seen your commitment, leadership, and growth over several seasons.
- An employer or internship supervisor who can speak to your reliability and how you work with others.
- An arts, music, or theater instructor outside school who knows your creative work well.
- A community leader who has worked alongside you on a sustained service project.
Before you ask, consider whether the letter would repeat what your teachers or counselor will already say. If your English teacher will describe your writing, a second humanities teacher adds little. A mentor who supervised your independent research, on the other hand, can show a side of you that no classroom letter covers.

What a Helpful Additional Letter Includes
A helpful additional letter is specific. It explains how long the writer has known you and in what role, then offers one or two concrete stories: the week you rebuilt an experiment that didn’t work, the season you mentored younger teammates, or the shift you trained a new coworker. It connects those stories to qualities colleges care about, such as curiosity, persistence, and how you treat other people. It also stays focused, so admissions readers can take in the new perspective quickly. You can make this easier by reminding your recommender of the moments you remember best and letting them decide what to include.
Questions to Ask Yourself Before You Add a Letter
Run through a quick check before you invite anyone beyond your required recommenders:
- Does this person know me in a setting my teachers and counselor haven’t seen?
- Can they describe specific things I did, rather than general praise?
- Does the college accept additional letters, and in what form?
- Would this letter support the story told by my essays and activities, or pull attention away from it?
If you can answer yes to the first three questions and the letter reinforces your story, it is likely worth including. If not, put that energy into your essays and your conversations with your required recommenders, where it will make a bigger difference.
How to Request and Submit an Additional Recommendation Letter
Once you decide an extra letter makes sense, give your recommender time and context. A few steps help the process go smoothly:
- Confirm each college’s policy. Check whether the school accepts an additional letter, how many it accepts, and whether it prefers a particular type, such as a peer recommendation.
- Ask early, and in person when you can. Give your recommender several weeks before your first deadline so the letter never feels rushed.
- Share a short brief. Include your activities list, the specific projects or moments you shared, and the qualities you hope the letter can illustrate.
- Send the invitation through the right system. On the Common App, your recommender can create an account only after you invite them from your application. [1]
- Follow up with thanks. A handwritten note, plus an update when you hear back from colleges, shows appreciation for their time.
Timing rules for extra letters can differ from those for required materials. Dartmouth, for instance, accepts peer recommendations after the application deadline and asks that they arrive within ten days of it. [4] Read each school’s instructions closely, note any separate dates on your calendar, and let your recommender know exactly when and where the letter should be submitted so nothing slips through the cracks during a busy fall.
Each additional letter is optional. Your counselor and teacher letters remain the core of this part of your application, so put the most care into choosing and preparing those recommenders first. InGenius Prep counselors often help students decide whether an extra letter would bring a new perspective to their file.
