Letters of recommendation are an important part of college applications. Colleges are a place to learn, and so they want to hear from your current teachers what kind of student you are, and how you contribute to an academic environment. We’ve written before about how important these letters are, and how to go about getting one that represents you well. Some colleges, however, accept letters of recommendation from other sources, particularly from mentors you have had. This, in turn, raises the important question of how important these letters are, whether or not you need one, and where you can get one. In this article, we’re going to explore the subject of supplemental letters of recommendation, so you can fully understand what colleges want from you.Ìý
Colleges That Accept Supplemental Letters of Recommendation
College applications are already quite long, and admissions officers spend months reading them. It’s not surprising then that not all colleges want supplemental letters of recommendation (indeed, there are some schools that don’t want rec letters at all). For your convenience, here is a chart of top colleges in the US, and their policies on letters of recommendation.
We have color coded this chart for ease of reading:
- Green means that additional letters of recommendation are accepted
- Yellow means that additional letters are allowed, but discouraged
- Red means that the college does not accept letter of recommendation at all
- No colors means that the school has a typical desire for recommendation letters; 1-2 teacher letters and a counselor letter, and does not accept supplemental letters

This is a lot of information, but we hope it’s clear enough. Now come the more important questions: where should you get a supplemental letter of recommendation, and how can having one benefit your application?
Who Should Write Your Supplemental Letter of Recommendation?
This is going to be highly dependent on your own circumstances, and what kinds of mentors you have access to. We’re going to first go over the traits you want for these letters generally, and then cover where these can come from.Ìý
What these letters need to do is provide a perspective on you that colleges could not otherwise get from your application. They need to add context, to explain who you are as a person and scholar in ways that go beyond what your teachers are able to say. This person needs to know you well, to be able to speak to your character, and to have seen you do things that your teachers haven’t.Ìý
Research Mentors
If you have pursued a research project, be it in a lab internship, a summer program, or overseen by a research mentor as you pursue an independent project, then this can be quite good to have a letter discussing. Colleges like to see that students have completed research, but are increasingly wary of students taking on non-credible research projects. We discuss this more in this article, but to sum up, many providers who claim to provide a research experience significantly under-deliver, and colleges are growing increasingly aware of this.Ìý
A letter from a research mentor both assuages these concerns from admissions officers, and gives confirmation of the work you did on a research project. Colleges trust you of course, but additional verification is always good. Research mentors are also able to speak to your performance in the act of research itself, just as teachers can speak to your performance in the classroom.
Employers
Work is separate from school, be it a highly competitive internship or simply working at a local restaurant. In both cases, however, how you perform at a job can be seen as a good indicator of how you will handle yourself in college when dealing with increased independence and responsibilities.
Many of the questions asked by colleges serve as a proxy to evaluate your maturity and ability to take responsibility. While an employer may or may not be able to speak well on your academic prowess (though some internships certainly can), they can certainly discuss your maturity and readiness for the responsibilities of college.Ìý
Coaches
The final core group you can turn to for additional letters of recommendation are coaches, be they athletic or overseeing you in debate or quizbowl. In most cases, this is unnecessary, but if you have an extracurricular you devote most or all of your time to outside of school, then an additional perspective and added context on what that entails can help admissions officers understand what you are doing there.Ìý
This is not necessary in most cases, only if there is something in what you have done that cannot be adequately described elsewhere in your application. As with employers, these are a good way to show off your character, maturity, and ability to take responsibility, especially under pressure.Ìý
Do You Need a Supplemental Letter of Recommendation for Your Application?
This is perhaps the most important question. Before you go out and start asking for supplemental letters, you should determine how they would benefit your application specifically. Here is our process for doing this with the students we work with:Ìý
Finalize their college list. We want to know which schools they’re applying to (if any) will accept these letters before we go looking for them. Applying to college is a lot of work, and we don’t want to saddle our students with any work they don’t need to do.
Plan out the narrative of their application. A college application tells the story of you, what you have done, and what your accomplishments mean to you. We then see if there’s any aspects of your narrative which would benefit from additional context. This is most common for students who have completed research, or for students with a significant extracurricular commitment which isn’t tied to their school.Ìý
Assess potential letter writers. If the student’s narrative would significantly benefit from the inclusion of a letter, then we assess who might be able to write one. Professors and research supervisors are well used to writing these, but even bosses may be amenable to serve as a reference. We help students determine how to ask, and how to fit this letter into the broader application.Ìý
When Not to Include a Letter
Do not include a letter just to highlight a connection to a somewhat famous or notable person. If you are a junior volunteer on a political campaign and shook hands with the candidate once, they cannot write you a letter of recommendation that means anything. This is also generally true for CEOs of companies, or important people your parents may know.Ìý
Also do not include a letter simply for the sake of including one. If it is going to repeat information already contained elsewhere in your application, then admissions officers won’t gain anything from reading it. Only include one of these letters if it adds something meaningful to what admissions officers will know about you.Ìý
Final Thoughts
Letters of recommendation are often overlooked by students, but are a key way for schools to gain an understanding of who you are as a person, the one piece of the application they get that you do not write. In certain circumstances, an additional letter of recommendation can add greatly to your application’s impact. We hope that this article has helped you understand how this works, and when you might want to include one of these letters.Ìý
The college application process is incredibly complicated, with many moving pieces to track, and many circumstantial occurrences which many students never consider. This all feels very overwhelming, and that’s where an expert guide can help. ³Ô¹Ï¹ÙÍø mentors have a deep understanding of the entire application process, and are experts at helping students tell their unique stories to admissions officers.
