No matter which topic you choose, BU sneaks in some of its core values right into the prompt: educational access, community service, diversity, and making an impact in Boston and the world. As you plan your essay, consider how your experiences relate to one or more of these themes.
Below, we’ll break down how to craft a strong response to each prompt and share examples to help inspire your own writing.
How to Write the Boston University “Community” Supplemental Essay
| Prompt |
| Reflect on a social or community issue that deeply resonates with you. Why is it important to you, and how have you been involved in addressing or raising awareness about it? (300 words) |
This prompt asks you to show values in action. Identify a specific social or community issue, explain why it matters to you personally, and describe concrete steps you’ve taken to address it or raise awareness about it. BU asks this to understand your civic engagement, initiative, and how you contribute to communities beyond yourself.

| The hallway outside the clinic smelled faintly of disinfectant and burnt coffee. A television replayed the same headlines while the receptionist turned the sign to “Fully Booked.” My brother’s appointment had been rescheduled again, for another four weeks.
That experience reshaped how I understood mental health care. I began noticing how often support depends on long waitlists, confusing referral systems, and families expected to navigate complex structures on their own. I wanted to understand why these gaps persist and how systems could be built to meet people earlier, not after they’ve reached a breaking point. This question drew me to psychology, particularly adolescent mental health and prevention-focused care. I pursued opportunities that addressed mental health from different angles. I founded Share2Care, a peer-support initiative that organizes mental health workshops and creates clear, student-friendly resource guides explaining how to seek help locally. I volunteered with Big Brothers Big Sisters, working one-on-one with middle school students navigating academic pressure and family instability. Through formal training in active listening and crisis response, I learned how early stress shapes self-concept, and why effective support depends on structure, boundaries, and knowing when referral matters more than resolution. I also became involved in student research through the Student Wellness and Burnout Study, where I assisted with survey design and statistical analysis examining links between stress, sleep deprivation, and academic burnout among high school students. Working with anonymized response data collected via Qualtrics reinforced what I’d observed firsthand: mental health challenges are rarely isolated events, but predictable outcomes of systems that neglect early prevention. Together, these experiences showed me that mental health care depends on infrastructure as much as empathy. I hope to study psychology in a setting where research, service, and advocacy work together to build systems that guide people to the support they need. (298 words) |
Essay analysis and tips
This prompt asks you to connect personal resonance with sustained action. The example begins with a specific moment close to the writer to show why the issue of systemic gaps in mental health care matters to them personally.
The essay zooms out to discuss how the student is involved in addressing mental health care or raising awareness of it. The writer doesn’t stop at founding Share2Care; they continue towards related mentorship (Big Brothers Big Sisters) and research (Student Wellness and Burnout Study). That range demonstrates commitment across service and inquiry, which are key to a university that values both community engagement and scholarship.
The essay reflects an understanding that lasting impact grows from coordinated efforts, shared responsibility, and thoughtfully designed processes rather than isolated action. This aligns with BU’s urban, service-oriented ethos and shows a mature understanding of complex social challenges.
When thinking of what issue to write about, reflect deeply on your day-to-day reality and anything you encounter that has pushed you to move towards a goal larger than yourself.
How to Write the Boston University “Why BU” Supplemental Essay
| Prompt |
| What about being a student at BU most excites you? How do you hope to contribute to our campus community? (300 words) |
BU asks this to assess fit and engagement. To answer this prompt well, you’ll need to explain why BU specifically excites you, and how you’ll actively contribute once you’re there. Highlight distinctive academic programs, research, student organizations, or Boston-based opportunities that align with your interests. Then explain how your skills, values, and experiences will shape the campus community.
| BU “Why BU” Supplemental Essay Example |
| The newsroom hummed as our deadline crept closer. I was covering an emergency school board meeting on proposed cuts to visual arts programs due to lack of funding, revising the introduction while the livestream played and the clock on the wall ticked louder by the minute. When the paragraph finally settled, accurate, balanced, and grounded in verified voices, I felt the familiar jolt of relief.
That experience clarified what excites me about journalism: the discipline of accurate reporting to uncover the ground truth when it matters. Journalism and reporting demanded patience and constant revision. Each edit revealed what was missing: a voice left out, context not yet earned, a detail that needed confirmation. Through this process, I learned to listen more closely and to treat the truth as an obligation to the students and teachers affected by the story. That commitment is what draws me to Boston University. I’m eager to take COM JO 200: Newswriting and COM JO 210: Reporting in Depth, where reporting skills are developed through hands-on work, and COM JO 350: Law and Ethics of Journalism, which examines the responsibilities journalists carry in newsgathering and dissemination. Beyond my school newsroom, JCAMP exposed me to professional reporting under pressure, ethical decision-making, and collaborative newsrooms. Its training in interviewing and fact-checking reinforced a core lesson I learned: good journalism requires preparation, humility, and respect for the people being reported on. At BU, I hope to bring that mindset to student media. I hope to contribute to The Daily Free Press and explore multimedia storytelling through BUTV10 or WTBU, reporting with precision, ethical responsibility, and an understanding of how different media platforms shape public trust.

Essay analysis and tips
This prompt asks two things: what excites you about BU, and how you’ll contribute to their community. The example above shows that the student is excited about studying journalism at BU and contributing to The Daily Free Press, among others.
The essay opens with a detailed scene that shows the writer is already deeply involved in campus journalism before BU is even mentioned. So, when courses like COM JO 200 and COM JO 350 are introduced, they feel like a natural extension of that passion.
The writer also provides concrete journalism training by referencing JCAMP and ethical reporting practices, showing they already have something to bring to The Daily Free Press, BUTV10, or WTBU, but are still excited to grow further as journalists as they explore multimedia storytelling through BUTV10 or WTBU.
As you approach this prompt, think about your passion and how it naturally fits into BU’s campus, culture, academics, or extracurriculars. Then reflect on how your habits, values, and experiences translate into contribution. Strong responses show mutual investment: why BU matters to you, and how you will actively shape the campus in return.
