UPenn's Trickiest Essay: The Thank You That Wins

UPenn's application includes a prompt that appears deceptively simple: write a thank you note to someone you have not yet thanked. Students read this prompt and immediately start writing about their favorite teacher, their coach, or a mentor who changed their trajectory. Those essays almost always underperform. Here's why — and what works instead.

Why Obvious Recipients Fail

Writing about a teacher, coach, or mentor is not wrong. It is predictable. UPenn's admissions team reads hundreds of essays thanking beloved high school teachers and inspiring coaches. These essays are difficult to distinguish from each other because the fundamental structure is the same: important person, meaningful guidance, gratitude. Without an unexpected element, the essay disappears into the crowd.

More importantly, writing about an expected mentor reveals something about your perception of who in your life has been valuable. Someone who immediately thinks of a teacher is thinking about people in positions of authority over them. Someone who thinks of a custodian, a neighbor, a barista, or a classmate no one else noticed is revealing that they pay attention to people across the full spectrum of their social world — not just the people above them in the hierarchy.

What the Choice of Recipient Reveals

Your choice of recipient tells UPenn two things: who you notice in your life, and what you value in other people. An unexpected recipient signals that you see humans holistically rather than by status or position. It suggests that you extract lessons from unlikely sources, which is exactly the quality UPenn's entrepreneurial culture prizes.

The quality of attention you pay to people who have no power over you — who cannot give you a grade, a recommendation, or a connection — is a more honest signal of your character than the attention you pay to people who can. UPenn understands this. The unexpected recipient is often the more revealing choice precisely because you have no strategic reason to have paid attention to them.

The Four Things the Essay Must Do

The essay is not just an expression of gratitude. It needs to do four specific things to succeed. First, identify an unexpected recipient and explain specifically what they did — not in general terms, but with a specific scene or moment. Second, explain what you learned from that interaction or relationship — not a universal lesson, but something specific to what that particular person showed you. Third, explain how you have applied or will apply that lesson. Fourth, connect it to who you are becoming and who you want to be.

The most common failure is stopping after the gratitude. Students describe what the person did and how they feel about it, but they don't explain what they learned or how they applied it. UPenn's culture is about extracting insight from experience and turning it into action. An essay that stays in the feeling rather than moving to the application is not fully demonstrating the UPenn mindset.

A Real Example of What Works

A student who thanks the custodian at her school who worked the overnight shift and whom she encountered during late-night study sessions. She describes a specific conversation where the custodian asked her why she was working so hard and listened to her answer with genuine interest — the kind of full, unhurried attention she rarely received from the adults in her life who were supposed to be her supporters. She explains what that quality of listening taught her about how to be present with people. She explains how she now applies that quality of attention in her work with younger students she mentors. That is a UPenn essay.

The UPenn DNA Connection

UPenn's culture — particularly Wharton, but across the university — is built around the idea of extracting value from unexpected sources, seeing opportunity where others see routine, and learning from every interaction regardless of the status of the person you're interacting with. The thank you essay is a test of whether you have that quality naturally. If you pick someone unexpected and explain specifically what you learned from them and how you applied it, you're demonstrating exactly the observant, entrepreneurially-minded character that UPenn is looking for.
