Tips for MBA Letters of Support—and How They Affect Your Application

December 15, 2025

Susan Cera

MBA letters of support—sometimes called MBA endorsements or informal recommendations—are an optional but valuable part of many business school applications. Applicants often wonder whether they need them, who should write them, and how much weight admissions committees give these submissions. In this blog post, we at Stratus explain what an MBA letter of support is, when it helps, and how to use one strategically in your application.

Anyone applying to business school knows that getting great recommendations will strengthen their candidacy. When selecting recommenders, you want to ask managers and mentors who will advocate for you and share specific examples of how you have contributed to and made an impact in an organization. See “Four Steps to a Five-Star MBA Recommendation” for more guidance on selecting recommenders.

What many business school applicants don’t know is that some programs value input from members of their community (e.g., alumni, current students, professors) in the form of endorsements or letters of support. But what, exactly, is a letter of support? And, if you don’t have any, does it mean that you won’t be accepted?

What Is an MBA Letter of Support?

A letter of support (sometimes called an MBA endorsement) is input from an individual who knows you well and can share insight about you as a potential student and community member of a specific business school. The content should focus less on your achievements and accomplishments and more on how your presence in that school’s MBA community would enhance the experience for other students. 

The letter should cover how long and in what context the writer has known you. They should discuss your motivation and commitment to your professional aspirations, how you engage with others as a teammate or leader, and your ability to communicate. If the writer doesn’t know you professionally, they should not discuss your work experience. Basically, the input should be a vote of confidence that the writer would want you to be sitting next to them in a business school class or working on a project team with them, or that they would be honored to call you a fellow graduate of their MBA program in a few years.

Who Can Submit an MBA Letter of Support?

Maybe your college roommate is a current student with whom you have been discussing your MBA aspirations. Alternatively, maybe your next-door neighbor—whose kids you babysat in high school and who trusts you to house sit when they are on vacation—is a faculty member. Perhaps a client with whom you have worked late hours for several months on a strategic project is a recent graduate. All of these people might be able to speak to your personal characteristics and fit with the program and would be great options to submit incremental insight to the admissions committee. Ideally, someone who is willing to write a letter of support on your behalf would offer to do so without you having to ask. However, some prospective endorsers may not be aware that submitting a letter of support for a prospective student is even an option.

If you engage with students as you are researching the resources of an MBA program, it would NOT be appropriate to ask any of them to write an endorsement. That said, be aware that a positive interaction could sufficiently impress a current MBA student who might feel compelled to share information about you with the admissions committee. On the flip side, a negative encounter could motivate a current student or staff member to alert the admissions committee that you are not a good fit with the program.

There is little to no value in asking a public figure who doesn’t know you personally to submit a letter of support. During my time on Duke Fuqua’s admissions committee, I saw several extra letters in applications that had been written years earlier by someone who barely knew the candidate and wrote a generic letter that “endorsed” the applicant for whatever job or school to which the individual was applying. This added no value and, in fact, made me wonder why the candidate felt compelled to submit the information with their application materials when the letter clearly had not been written specifically for the program. In the end, this additional information likely had a negative impact on the applicant’s candidacy, as it demonstrated a lack of awareness.

Similarly, a friend of your parents who attended your dream MBA program 20-plus years ago and has never met you would not have any valuable insight to share with the admissions committee. Even if they WANT to write something on your behalf, perhaps to enhance their relationship with your parents, you should thank them for their willingness but discourage them from submitting anything.

How Do You Submit an MBA Letter of Support?

Individuals who want to share their insight on a business school applicant can send an email directly to the admissions committee using the email address to which you would make an inquiry about the admissions process. The email should include your name and any identifying information such as an application ID in the subject line. This will allow the MBA admissions operations team to match the letter with your electronic file. Some MBA programs, such as Duke’s Fuqua School of Business, have a form that individuals who want to endorse a potential student can fill out. Candidates who are considering the Northwestern Kellogg School of Management might ask someone who knows them well to refer them. In some instances, having a referral or endorsement will result in an application fee waiver.

You should not submit letters of support with your application. Letters of support should only be submitted by the individual who is endorsing your candidacy.

When Should Someone Submit an MBA Letter of Support?

If a school offers an application fee waiver for candidates who have an endorsement from a student or graduate, your endorser should submit their insight before the application deadline. Otherwise, you want to make sure the input is in your file before decisions regarding interview invites are made—within about two weeks of the submission deadline. If you are put on a waitlist, an additional letter of support could offer the admissions committee more insight into your candidacy that could result in an acceptance in a later round.

Do All Programs Accept MBA Letters of Support?

Not all MBA programs welcome additional input in the form of endorsements or support letters. Someone who is intimately familiar with the program should know whether an extra endorsement is acceptable or welcome. If someone you know well offers to support your candidacy, suggest that they reach out to the admissions committee to determine if their contribution would be appreciated.

MBA letters of support are a bonus for applicants who have a personal relationship with someone who is associated with the MBA program to which they are applying. Not having an additional endorsement will not adversely affect your prospects of admission. However, use caution when asking for endorsements, and don’t attempt to pad your application file with numerous letters.

MBA Application Tips for LGBTQIA+ Candidates How Will Job Hopping Look on My MBA Applications? July ##, 2024 Susan Cera If you look at the class profiles for top MBA programs, you will note that the average incoming student has four or five years of work experience. Generally, about 80% of students have between three and eight years of post-undergraduate work experience. However, each individual’s professional journey during that time is unique. Some applicants have worked for the same company the entire time and received one or two promotions. This is common for strategy consultants. Often, applicants who are engineers have stayed at a single company and may not have been promoted at all. Meanwhile, the typical pre-MBA profile for many in finance consists of two years working in investment banking followed by two years in private equity. So, how will it look if you have had three or even four jobs over five to eight years before applying to business school? As with anything related to MBA admissions, it depends. The admissions committees’ view of a candidate who has had several jobs before applying is nuanced. Through the application process, you need to explain why you transitioned from one job to another and how your current role sets you up to be successful in an MBA program. Like any other applicant, individuals who have held more than one job will need to clearly articulate why NOW is the right time to attend business school and how an MBA will position them to achieve their short- and long-term goals. Taking Steps Toward a Focused End Goal One of my clients was on her third job in five years when she applied to business school. Her first role directly out of college with a degree in computer science was as a product manager for a startup, where she wore a lot of hats. Beyond understanding the needs of a niche customer base (i.e., senior citizens using technology), she designed packaging and conducted A/B testing on marketing campaigns. Given the size and stage of her employer, she was able to work on many projects, but the scope was small and she wasn’t getting a lot of guidance. After just over two years in her first role, she moved to a product marketing role in a more established company, where she led messaging for five products with a global reach. During this time, she realized that she missed working closely with customers and leveraging her technical skills to craft solutions that addressed consumer needs. She knew that she wanted to become a tech product manager, and since she wasn’t able to make an internal pivot, she looked for a role outside of her company. Her third job was closest to her end goal—but rather than working with consumers, the product she was working on targeted businesses. However, it was through these diverse experiences in a variety of technology companies that she was able to identify and articulate why an MBA was the best next step to position herself for her career moving forward. When she lost her job due to the COVID-19 pandemic, she had already done a lot of thinking about where she wanted to take her career and what skills, knowledge, and relationships she needed to get there. She was able to take advantage of extended deadlines in 2020, applied a year before she had intended to, and she was accepted to several top 15 MBA programs and ultimately attended Berkeley Haas. Exploring Early to Uncover Passion and Fit Another client, an undergraduate business major, had worked in four roles in five years before applying to business school. Her first position out of college was as an investment analyst focused on fixed-income investments. She realized pretty quickly that this was not what she wanted to be doing long term, so she took a job as a product manager in the gaming industry, where she was able to gain exposure across functions. Despite thriving, she felt pigeonholed and realized that she wanted to be working more strategically, so she joined a big tech firm in a strategy and operations role. Unfortunately, she had expected to apply to MBA programs from this role but recognized that her manager did not support her academic ambitions and would not write a strong recommendation. Her life experience was global in nature, so as she was exploring new roles within her company, she looked for an opportunity to tap into her personal commitment to Asia. She secured a role focused on lifting up entrepreneurs in the region, reporting to a manager who had an MBA and understood the value of going back to school. By the time she applied to MBA programs, she had worn a lot of hats and knew what she did and didn’t want to do. This allowed her to craft a strong story that spoke to how the skills she had learned in each job set her up for the next—ultimately positioning her to attend Wharton. Following a Haphazard and Opportunistic Trajectory Another client of mine had worked at five jobs in just over six years and hadn’t been with any company for more than two years. He had no clear upward trajectory or consistent function or industry. Furthermore, his last position had been a six-month contract, and when he applied to business school, he was a “private investor” in blockchain who paid the bills by playing professional poker. Needless to say, his erratic work history was a red flag to admissions committees, and he wasn’t able to secure a seat in his target MBA program. Changing Jobs Just Before Applying (or During the Application Process) Many prospective applicants have asked me if they can leave their job before they apply to business school. This is not advised, as the admissions committees expect students to be able to balance schoolwork, extracurricular engagements, and recruiting. If you cannot prepare for a standardized test and work on your MBA applications while performing at your day job, it is unlikely that you will thrive in the high-pressure environment of a top business school. I also advise against switching jobs (with the exception of an internal transfer) in the months leading up to submitting applications. One of the stakeholders in the MBA admissions process is the career office, and they are responsible for ensuring that individuals graduating from the program can secure the positions to which they aspire. Recruiters don’t look favorably upon candidates who take a pre-MBA job when they are planning to leave the company in less than a year. Companies that recruit from top MBA programs invest a substantial amount of time and money in onboarding top performers. Therefore, they don’t want to make a job offer to someone who isn’t going to commit to their organization for several years post-MBA. Another challenge related to switching jobs immediately before applying to business school is securing a recommendation from your current immediate supervisor. If you have only worked with your manager for a few months, it is unlikely that you have made a significant impact or that your manager has observed your work in a meaningful way. Consequently, they won’t have much to say about your candidacy. And if you don’t have a recommendation from your manager, the admissions committee might be concerned. Every MBA aspirant has taken a unique path to submitting their applications. There is not one “correct” path to an MBA.
