How to Write Supplemental Essays for College Applications + Examples [2025]

If you’re wondering how to write supplemental essays while juggling everything else in the college application process, you’re not alone—and you’re not behind. These essays may seem like just another box to check, but each one is a chance to add something new and meaningful to your admissions story. Whether it’s a short answer or an essay that asks you to reflect on the experiences that have shaped you, schools will ask questions to see what matters to you.

In this step-by-step guide, I’ll show you how to write supplemental essays that are clear, thoughtful, and personal. With the right approach, you can write the essays you must write with more confidence and less stress.

So, What Is a Supplemental Essay?

When you apply to college in the United States—especially through the Common Application—you’ll often see additional short-answer questions or writing prompts for each school. These are the supplemental essays. They’re not meant to duplicate your personal statement. Instead, they give admissions officers a better sense of your personality, values, academic interests, and how you might fit into their campus community.

Some of the most common supplemental essay prompts include:

• “Why this school?”
• “Describe a community you’re part of.”
• “Tell us about an extracurricular activity that matters to you.”
• “How do your interests align with our program?” (especially popular in computer science and science majors)

Different colleges, like Princeton University, Stanford University, or an Ivy League school like Brown with its open curriculum, all ask different questions, but the goal is the same: to help the school see why you belong there.

How to Start: Read, Reflect, and Brainstorm

Before you even write an essay, start by reading each supplemental question carefully. Many students jump straight into writing, but taking time to understand what the school is really asking can save you a lot of frustration later. Remember: college admissions in the United States aren’t about tricking you. These questions are your opportunity to show how you think, what you value, and how you see yourself contributing to the school.

Once you’ve read the prompt, pause and reflect. This is your chance to figure out what personal experience or story fits best. Don’t aim for perfection—just aim for honesty.

Here’s how to begin your brainstorm:

• Jot down quick ideas that pop into your head. No need to write full paragraphs yet. Think about small moments—maybe an anecdote from an extracurricular, a class that changed how you see things, or a time you stood up for something important.
• Look for overlap between your own life and the college’s mission. If you’re responding to a “Why us?” prompt, ask yourself: What does this school offer that fits your goals, values, or interests? Maybe they prioritize creativity, have a strong computer science program, or support research in race and ethnicity in the United States Census. These are all potential angles to explore.
• Think specifically. For example, a prompt like “Describe that community you’re part of” could apply to your family, school club, sports team, online group, or your neighborhood. You might write about a group connected by shared geography, or your intellectual heritage as a first-generation student. Focus on how you were involved, what you learned, and how that experience shaped you.

The goal of this stage isn’t to write a perfect college application essay. It’s to figure out what you want to say, and how to say it in a way that’s personal and relevant.

Writing Tips: Make Every Word Count

Once you’ve done the hard work of brainstorming, it’s time to write an essay. At this point in the writing process, focus on being clear, personal, and specific. The best supplemental college application essays don’t try to sound impressive—they sound real.

Here’s how to approach the essay writing process:

• Answer the essay question directly. If it’s a “Why us” essay, don’t give general statements like “I want to attend an Ivy because it’s prestigious.” That won’t help. Instead, mention something school-specific—like a course you’re excited about, a professor’s research you admire, or a student group you want to join.
• Make your essay personal. This isn’t the place for a list of achievements. Instead, tell the admissions committee something meaningful about your experience or values. If you’re writing about race, an extracurricular, or an academic interest, share a moment that shaped your point of view. That anecdote could make all the difference.
• Stick to one main idea per essay. Many college essay prompts have short word limits. Use that space to focus on one specific experience or idea. If the word count is 250 words, one strong paragraph can be enough—if it’s focused and clear.
• Edit ruthlessly. Once you have a draft, cut anything that’s vague, repetitive, or off-topic. Editing is where your essay goes from decent to great. Ask yourself: Does every word help answer the prompt? Does it sound like me?

• Don’t write in vague or generic language. Phrases like “I’m passionate about helping people” won’t stand out. Instead, give concrete examples. For instance, describe that time you organized a fundraiser, tutored a younger student, or started a club. These real moments help the reader connect with you.

Your application essay is a chance to show—not just tell—how you think and what matters to you. If you’re stuck, check out supplemental essay examples online or revisit your Common App essay to avoid repeating ideas.

Common Mistakes (and What to Do Instead)

Even the strongest students make mistakes when writing supplemental college application essays. The good news? You can avoid them by knowing what not to do.

Mistake #1: Copy-pasting the same essay for every school

Don’t write one generic essay and submit it everywhere. Admissions officers already know when your answer could apply to any college. Take time to tailor your answer to each school’s values, programs, and culture. That’s what makes a strong supplemental essay.

Mistake #2: Repeating your main essay

You’ve probably already written a Common Application essay. The supplementals aren’t meant to repeat that. They’re a chance to show different sides of you. If your main essay was about a family tradition, maybe your supplemental essay can focus on an academic passion or community involvement.

Mistake #3: Waiting too long to start

College admissions deadlines come fast. Many students leave supplemental questions for last. But these essays often take just as much time (if not more) than your main essay. Start early so you have time to edit, reflect, and improve your writing.

Mistake #4: Trying to sound overly formal or complex

Many students think they have to sound academic or poetic. But big words won’t make up for weak content. Plain English is your friend. Be direct, be clear, and focus on substance over style. A simple piece of writing that answers the essay question honestly is always better than a flashy one that says little.

What to Do Instead

• Show your personality through real experiences.
• Keep your answers focused and specific.
• Use the essay to show how you think, not just what you’ve done.
• Be honest, not perfect.

Think of your college application essay as a conversation. You’re speaking directly to the people who will read your application. You’re saying: “This is what I’ve learned. This is what I care about. And here’s why your school, rather than another, is where I see myself growing.”

That’s what admissions officers want.

What Admissions Officers Are Looking For

Admissions officers reading your essays are trying to build a class of students who are curious, thoughtful, and excited about learning. Your answers help them figure out how you might contribute to their school’s culture, academics, and student life.

Some essays are a chance to show how you think (like describing your approach to a challenging question). Others are about values, identity, or your role in your community. The key is to keep it honest, specific, and personal.

They’ll notice if you’ve done your homework—if you mention a specific program, club, or professor at Stanford University, or talk about how Brown’s open curriculum fits your learning style. That kind of detail helps them see you as a real fit.

Supplemental College Essay Examples

Example 1: “Why Us?” Essay for Yale University

Prompt: What is it about Yale that has led you to apply?

Response:

When I first visited Yale in March 2023 during my junior year, I was struck by the balance between tradition and innovation across campus. Sitting in on a Global Affairs seminar taught by Professor Bonnie Jenkins, I listened as students debated international climate policy using both historical context and forward-looking models. I knew then that I wanted to be part of that level of discussion.

My interest in environmental diplomacy began during my sophomore year at Walter Payton College Prep in Chicago, when I led a community initiative to lobby our city council to increase green spaces in underfunded neighborhoods. At Yale, I’m excited by the opportunity to study under the Jackson School of Global Affairs and join the Yale International Relations Association. I also plan to participate in the Yale Undergraduate Consulting Group, where I can apply data analysis to real-world climate challenges.

It’s not just the academic opportunities that attract me—Yale’s focus on community resonates deeply. During Bulldog Days in April 2023, I stayed in Timothy Dwight College, where I was welcomed by students who spoke about their residential college as a second family. That spirit of shared curiosity and support confirmed for me that Yale is where I want to grow, learn, and lead.

Example 2: “Describe a Community” Essay for University of Michigan

Prompt: Everyone belongs to many different communities and/or groups. Describe one of your communities and your place within it.

Response:

In May 2020, as COVID-19 shut down our city, I joined a group of Somali-American students in Minneapolis to form the Dhalinyarada Writers Circle, a virtual storytelling community created to preserve our cultural narratives and support one another through isolation. What started as a weekly Zoom session quickly evolved into a space of creative energy, activism, and healing.

As one of the founding members, I proposed our first group project: to collect oral histories from Somali elders in our families and transcribe them into bilingual zines. My role was to edit these stories and ensure that the Somali dialects were preserved accurately in translation. Through this, I deepened my appreciation of the nuances of language, tradition, and generational memory.

The community has shaped me into a bridge—between generations, between cultures, and between ideas. I see the University of Michigan as an extension of this work. With programs like the Arab and Muslim American Studies Initiative and the Trotter Multicultural Center, I believe I can contribute to a larger dialogue on race, ethnicity, and shared experience within the United States.

Example 3: Short Answer Essay for Stanford University

Prompt: What historical moment or event do you wish you could have witnessed?

Response:

I wish I could have stood in the crowd outside the Lincoln Memorial on August 28, 1963, during Dr. Martin Luther King Jr.’s “I Have a Dream” speech. That moment—when words met conviction and reshaped the moral consciousness of a nation—embodies everything I believe about the power of rhetoric and peaceful resistance.

At North Springs High School in Atlanta, I’ve studied the speech not just as a historical artifact, but as a literary masterclass in structure, metaphor, and emotional resonance. I even wrote my junior thesis in 2023 on its influence on modern political communication.

Being present that day would’ve meant feeling the collective hope in the air, watching history move not through laws or battles, but through language—a reminder that words, when chosen with care, can change the course of justice.
