What Are Current Penn's Supplemental Essay Prompts?
Penn requires three supplemental essays for all applicants. Two are universal; the third depends on which undergraduate school you're applying to. All three have a strict 150-200 word limit.
Here are the exact prompts:
Prompt 1 (All applicants)
Write a short thank-you note to someone you have not yet thanked and would like to acknowledge. (We encourage you to share this note with that person, if possible, and reflect on the experience!)
Prompt 2 (All applicants)
How will you explore community at Penn? Consider how Penn will help shape your perspective, and how your experiences and perspective will help shape Penn.
Prompt 3, School-specific (choose one based on your school)
- College of Arts & Sciences: The flexible structure of The College of Arts and Sciences' curriculum is designed to inspire exploration, foster connections, and help you create a path of study through general education courses and a major. What are you curious about, and how would you take advantage of opportunities in the arts and sciences?
- Wharton: Wharton prepares its students to make an impact by applying business methods and economic theory to real-world problems, including economic, political, and social issues. Please reflect on a current issue of importance to you and share how you hope a Wharton education would help you to explore it.
- Penn Engineering (SEAS): Penn Engineering prepares its students to become leaders in technology by combining a strong foundation in the natural sciences and mathematics with depth of study in focused disciplinary majors. Please share how you plan to pursue your engineering interests at Penn, particularly within the intended major you selected.
- Penn Nursing: Penn Nursing intends to meet the health needs of a global and multicultural society by preparing its students to advance science that impacts healthcare. Why have you decided to apply to Nursing? Where do you see yourself professionally in the future, and how will you contribute to our mission of promoting equity in healthcare?
That's three essays, each under 200 words. But each one needs to do real work in your application.
Penn is one of the most selective schools in the country; you're probably applying to several Ivies at once. If you're also working on Harvard supplemental essays, note that this school has very different prompt structures and tone expectations.
Penn's essays are shorter and more specific than Harvard's, and less thematic than Yale's supplemental essays.
Writing Penn's Supplemental Essays Prompt 1: The Thank-You Note
Penn's first prompt is different from anything else you'll write this cycle. You're writing an actual letter to someone who made a difference but hasn't heard about it yet.
What Penn is really looking for
The thank-you note comes from positive psychology research on gratitude. Penn isn't just collecting polite letters. They want to see whether you can recognize impact in your own life, reflect honestly on a relationship, and write something genuine rather than formulaic.
Four things that separate a great thank-you note from a forgettable one
1. Pick someone unexpected.
The prompt says "someone you have not yet thanked", that's a signal. Your parents have probably been thanked. Your coaches, too. Think about the people who shaped you without realizing it: a librarian who handed you the right book, a classmate who challenged your thinking without trying to, a neighbor who asked the right question at the right time. |
2. Anchor it in a specific moment.
Don't write "you always believed in me." That's generic. Write about the Wednesday afternoon in tenth grade when you froze up during a presentation, and this person did one concrete thing that changed how you felt about yourself. |
3. Name what actually changed.
The payoff is the effect, not the affection. How did this person change how you think, what you try, and what you believe about yourself? That's the chain of cause and effect Penn wants to see. |
4. Write it like a real note.
Read it aloud. If it sounds like a college application, rewrite it. The format is a letter, your voice should be in it. |
Full Example: Thank-You Note (College of Arts & Sciences Applicant)
Dear Mr. Reyes,
You probably don't remember the day you handed me The Dispossessed and said, "I think you'll argue with it." I was a sophomore who thought science fiction was for people who didn't read real books. I was wrong.
That novel broke something open for me. I started asking whether the systems I live inside, economic, social, and scientific, were chosen or just inherited. It led me to Ursula Le Guin, then to political philosophy, then to the question I've been chasing since: why do societies build the boundaries they do?
You didn't tell me what to think. You trusted me to argue my way to something. That's the best thing a teacher can do.
I did share this with you before I sent it in. You told me to keep going. I will.
With gratitude, [Name]
Why This Works
It opens on a specific moment, not a vague tribute. It names the exact book and explains the chain of effect that followed. The reflection is genuine ("I was wrong"), the ending is tight, and it sounds like a person wrote it, not a college application.
Full Example: Thank-You Note (Wharton Applicant)
Dear Mrs. Okafor,
You were the first person who told me that my obsession with why our corner store kept failing wasn't annoying, it was economics.
I was twelve, and the family that ran it kept changing their prices in ways that made no sense to me. You sat with me for two hours on your porch, teaching me about demand elasticity and sunk costs. You weren't a teacher. You worked in logistics. But you treated my questions like they were worth answering carefully.
That conversation is why I started reading about small business credit gaps in underserved neighborhoods. It's why I'm applying to Wharton. The question you helped me take seriously, why do some businesses survive and others don't, and what does that say about who gets resources, is still the one I'm trying to answer.
Thank you for taking a twelve-year-old's curiosity seriously.
[Name]
Why This Works
The specificity (age, the porch, logistics background) makes it vivid. The chain from that conversation to Wharton's application is clear. It says something new about this applicant, something the rest of the application probably doesn't cover.
This same principle, one real moment tied to a real effect, applies across Ivy essays. If you're writing Columbia supplemental essays alongside Penn, Columbia's "Why Columbia?" prompt rewards exactly the same kind of specificity: a genuine experience tied to a genuine resource, not a generic pitch.
How to Write Prompt 2: Community at Penn
Most students answer half of this prompt. Don't do that.
The prompt has two parts: How will you explore community at Penn? AND how will Penn shape your perspective while your experiences shape Penn?
That second part is a two-way exchange. Penn isn't asking what you'll get from them. They're asking what you'll bring, and they want both in 150-200 words.
The Structure that Works
|
What to Avoid
Listing five clubs you read about online without explaining why they matter to you is the most common mistake. So is writing only about what you'll gain, or using lines like "I want to contribute to Penn's diverse community." Those phrases are invisible. Penn reads thousands of them.
Schools like MIT and Northwestern have community-style prompts too, but they each look for something slightly different. MIT wants to see what you'll build alongside others. Northwestern wants to see why its specific environment is the right one for you. Penn's unique angle is the explicit two-way exchange: what you'll take and what you'll give back. |
Full Example: Community Prompt (SEAS Applicant)
Growing up, I was often the only person in the room who saw a broken system as an invitation rather than a wall. When our school's internet went down during finals week, my classmates vented. I mapped the network, found the single-point failure, and got it back up. That instinct, treat every failure as data, is how I've always learned.
At Penn Engineering, I want to bring that same orientation into the Penn Electric Racing team, where problems don't just need solutions, they need teammates who know when to scrap an assumption. I also plan to connect with Penn First Plus. Being a first-generation student, I've learned to navigate systems without a map. I want to offer that navigational knowledge to students who are starting where I started.
Penn will push my technical thinking through the depth I can't build alone. What I'll give back is a stubborn belief that failure is just underexplored data.
Why this Works
The opening image (fixing the network) is specific and tells us something real about this person. The Penn connections (Electric Racing, Penn First Plus) are researched and tied to actual experiences. The closing exchange is genuine and concise.
Full Example: Community Prompt (CAS Applicant)
In my grandmother's kitchen, I learned that translation isn't just about words, it's about making someone feel heard in a language that wasn't built for them. I spent two years translating at free legal clinics for Spanish-speaking immigrants in our county, and what I learned wasn't just vocabulary. It was how much meaning gets lost when systems don't account for who's actually in the room.
At Penn, I want to take that into La Casa Latina and the College Houses, where interdisciplinary conversations happen across different lived experiences. I'm also interested in Professor Mary Frances Berry's work on civil rights policy. I want to understand the legislative architecture behind the moments I've already seen up close.
Penn's flexibility in CAS means I don't have to choose between studying language, law, and history. That intersection is exactly where I want to be. And what I'm bringing with me is two years of knowing what's lost when we don't listen carefully enough.
Why this Works
Specific experience, specific Penn resources (La Casa Latina, College Houses, a named professor), and a clear two-way exchange. It doesn't feel like research; it feels like a person who's thought this through.

How to Write Prompt 3: Your School-Specific Essay
This is where your application diverges based on which school you're applying to. You only write one of the four below.
College of Arts & Sciences: The Curiosity Essay
The prompt asks: What are you curious about, and how would you take advantage of opportunities in the arts and sciences?
This isn't a simple "why CAS?" prompt; it's asking about the intersection of your curiosity and Penn's specific curriculum structure. CAS is built around interdisciplinary exploration. The best answers name two departments or fields and show how Penn's flexibility lets you pursue the question at their intersection.
The structure that works:
|
If you're also applying to other liberal arts-oriented schools, Brown's supplemental essays ask a similar curiosity question, but Brown specifically wants to see open curriculum thinking, while Penn CAS wants to see how two disciplines intersect around a real question you're already carrying.
Full Example: CAS School-Specific Essay
Why do some people remember trauma in vivid sensory detail while others rebuild it into a narrative? That question has been following me since I read Oliver Sacks at fifteen and couldn't stop thinking about the gap between what the brain records and what the mind tells itself.
At CAS, I want to bridge the Psychology Department's cognitive neuroscience research, particularly the work on memory reconsolidation, with the English Department's focus on life writing and autobiographical narrative. I'm drawn to the College Houses as a space to continue those conversations outside the classroom, and I'd want to explore the Biological Basis of Behavior program as a way to stay grounded in the science while I read theory.
The question I'm carrying to Penn isn't one discipline's to answer. It lives at the intersection. CAS is the only place I've found where that's treated as a feature rather than a problem.
Why this Works
Specific question, two named departments, two specific Penn resources, and an ending that explains why CAS specifically, not just Penn in general.
Wharton: The Issue + Education Essay
The prompt asks: Please reflect on a current issue of importance to you and share how you hope a Wharton education would help you to explore it.
This is a hybrid: issue + fit. Most students pick an issue that's too broad ("income inequality," "climate change") or too vague to anchor a Wharton argument. Pick something specific enough that Wharton's actual resources, courses, labs, programs, and the Public Policy Initiative are the natural next step.
The structure that works:
|
Students applying to both Wharton and other business-adjacent programs often ask how Penn compares to other schools. Cornell supplemental essays, particularly for Dyson or ILR, also reward issue-based specificity, but Cornell tends to want to see how you'd act on the problem. Wharton wants to see how you'd analyze it first.
Full Example: Wharton School-Specific Essay
Small business lending in immigrant communities operates on trust, and almost nothing else. When my uncle's restaurant couldn't qualify for a traditional SBA loan after COVID, he borrowed from a lending circle organized by a neighbor. That informal credit system saved the restaurant. It also left no paper trail, no credit history, and no path to growth financing.
I want to understand why formal credit markets fail specific communities and whether alternative lending models can scale without losing what makes them work. At Wharton, the Public Policy Initiative and the Social Impact Consulting Group are the places where that question gets taken seriously, not just as a social problem but as a market design problem. I'm also drawn to Professor Keith Weigelt's game theory research, which I think applies directly to how trust-based systems compete with formal institutions.
Wharton gives me the economic tools to ask this question rigorously. The question came from my family's kitchen table.
Why this Works
The issue is specific (informal credit in immigrant communities), the personal connection is grounded in a real moment, and the Wharton resources are named with actual reasoning, not just dropped in for effect.
Penn Engineering (SEAS): The Engineering Focus Essay
The prompt asks: Please share how you plan to pursue your engineering interests at Penn, particularly within the intended major you selected.
SEAS wants three things: your specific engineering passion, your intended major, and how Penn's particular resources connect to both. "I've always loved engineering" is not an answer. A specific problem you want to solve and a clear path to solving it through Penn's resources is.
The structure that works:
|
If you're also applying to Stanford for engineering, the approach shifts noticeably.
Stanford's supplemental essays are more about your values and how you think about your work. Penn SEAS is the most explicitly "show me your technical path" of the three: name your major, name your problem, name your Penn resource.
Full Example: SEAS School-Specific Essay
I want to design neural interfaces that restore motor function in patients with incomplete spinal cord injuries, people who have movement potential that current rehabilitation technology can't unlock.
My interest in bioengineering started when I volunteered at a rehabilitation center and watched a patient spend six months relearning to lift a spoon. The technology in the room was decades old. That gap between what neuroscience knows and what rehabilitation engineers have built is where I want to work.
At Penn Engineering, I'm drawn to Dr. Brian Litt's neural engineering lab, which works at exactly the intersection of neural signal processing and therapeutic application I'm trying to reach. The SEAS curriculum's emphasis on combining mathematical fundamentals with depth in a focused major means I can build both the signal processing fluency and the biological understanding this work requires.
The patient I watched that day eventually got the spoon to his mouth. I want to build the tools that get there faster.
Why this Works
Specific problem, specific major (bioengineering), specific Penn resource (Dr. Litt's lab), and a closing image that circles back to the opening. It sounds like an engineer who's already thinking about impact.
Penn Nursing: The Healthcare Mission Essay
The prompt asks: Why have you decided to apply to Nursing? Where do you see yourself professionally in the future, and how will you contribute to our mission of promoting equity in healthcare?
Penn Nursing wants to see two things: a grounded origin story and a future-facing vision. "I want to help people" is not either of those things. A specific moment where you encountered a healthcare gap, and a clear idea of the professional path that flows from it, is what makes this essay work.
The structure that works:
|
If healthcare equity is central to your application, you may also be looking at NYU supplemental essays. NYU has a strong nursing and global health program, too.
The key difference is that Penn Nursing explicitly asks you to address science and equity together, which requires a more research-forward framing than NYU typically expects.
Full Example: Penn Nursing School-Specific Essay
When I was fourteen, I sat in a waiting room with my grandmother while a doctor explained her diagnosis in English she didn't fully understand. I translated as best I could. But I missed the part about side effects. She stopped taking the medication three weeks later because she thought she was fine.
That waiting room is why I want to become a family nurse practitioner specializing in geriatric care for Spanish-speaking communities. Nurses are often the people who catch what gets lost in translation, not just language, but cultural context, family structure, economic constraints.
At Penn Nursing, I want to work with the NewCourtland Center for Transitions and Health, which focuses on aging populations and community-based models of care. I'm also drawn to Penn's global health programs, which take seriously the idea that healthcare equity isn't just a local problem.
I'm bringing a specific kind of knowledge to Penn Nursing, what it costs when patients don't fully understand what they've been told.
Why this Works
The opening moment is specific and vivid. The professional direction is named clearly. The Penn Nursing resources are tied to the experience, not just listed. The closing line is precise and quotable.
Common Penn Supplemental Essay Mistakes to Avoid
These patterns show up in weak Penn supplements every year.
Going generic on the thank-you note.
- The prompt says "someone you have not yet thanked", that's a hint to go unexpected. A note that could have been written by any applicant to any school won't land.
Only answering half the community prompt.
- Penn asks for a two-way exchange. If your essay is 90% about what you'll gain from Penn and nothing about what you'll bring, you've missed the point of the prompt.
Name-dropping without connection.
- Listing clubs and professors without explaining why they matter to your specific experience reads like research, not fit. Every Penn resource you mention should connect back to something real about you.
Treating the word limit as an obstacle.
- 150-200 words is a design. It forces clarity. Write to 220, then cut to 190. The cuts usually improve the essay.
Repeating your personal statement themes.
- Penn reads all your essays as a set. If your personal statement, thank-you note, and community essay are all about the same experience, you've given admissions officers one dimension. Use the supplements to add different angles.
How to Think About All Three Penn Supplemental Essays Together
Penn's essays are a package. Before you submit, read them as a set.
Ask yourself: Do these three essays, plus my personal statement, show different parts of who I am?
A strong set might cover a relationship that shaped you (thank-you note), how you engage with communities (Prompt 2), and what you're intellectually driven to pursue (school-specific). They don't have to be dramatically different, but they shouldn't all be saying the same thing.
| The test: Could someone else submit your three essays? If yes, they're not specific enough. Penn should be able to read all three and picture you specifically, not a type of student. |
A Note on Penn Supplemental Essays 150-200 Word Limit
Penn will see if you go over. Stay within the limit.
| The cleanest approach: write to 220 words, then edit down to 185-195. The cuts almost always make the essay better. Every sentence you cut was probably a hedge or a repeat. |
Read your drafts aloud. Your ear catches things your eye skips, especially sentences that sound like an application instead of a person.
