Guide for students writing supplements
Supplemental Essay Examples and How to Write Yours
A short example of each kind of supplement, how to write a why us essay that fits one college, and 21 colleges' 2026–27 prompts in one table.
A supplemental essay is a short answer a college asks for on top of your Common App personal essay. Most are 50 to 250 words, and nearly all fall into four kinds: why us, community, academic interest and short takes. Harvard asks five 150-word answers, Duke asks two of 250 words, and UVA asks most applicants none at all.
Below is a short example of each kind, written for this page so you can see the moves without copying anyone's real essay. Then come the steps for a why us essay, how to reuse a story without repeating yourself, and a table of 21 colleges with what each asks in 2026–27.
To draft yours, the supplemental essay writer plans every college on your list from your own stories, and the why this college essay writer handles the why us question on its own.
The four kinds of supplemental essay, with examples
Colleges word their prompts differently, but each one is asking one of four things. Name the kind first and you know what the answer has to prove. Each example below was written for this guide by a made-up student; none is a real applicant's essay.
The four kinds at a glance
| Kind | What it really asks | Real 2026–27 prompt | Typical length |
|---|---|---|---|
| Why us | Why this college, and why you fit it | Columbia: "Why are you interested in attending Columbia University?" | 150 to 300 words |
| Community | Which group shaped you, and what you would bring | Duke: "Tell us about a community that has shaped who you are" | 150 to 250 words |
| Academic interest | What you want to study, and the proof you already care | Princeton, Yale, UIUC, Michigan's college essay | 150 to 550 words |
| Short takes | Who you are in a few words | Stanford's five 50-word questions, USC's Quick Takes, Yale's short takes | A list to 50 words |

My grandmother ran a pharmacy counter in Kinston for thirty years, and half her customers asked her, not their doctor, what their pills were for. I want to spend a summer like hers, so DukeEngage is the first thing I looked up. A program that funds students to work with a community for eight weeks is the closest thing I've found to her counter.
- What it does. It starts with the student, not the college, then names one real program and says why this student needs it.
- Check it. Swap "Duke" for another college's name. If the paragraph still works, it isn't specific enough yet. DukeEngage is a real Duke program; check that every program you name exists and still runs.
Every Sunday at 6 a.m., eleven of us unload the food bank truck behind St. Mark's. Nobody talks until the second pallet. I joined because my brother had to, for community service hours. I stayed because Mr. Alvarez, who has driven that truck for nine years, taught me to stack cans by expiration date and to remember the names of the families who come early.
- What it does. It shows the community at work before saying what it means. The last sentences of the full answer would say what the student brings to the college's version of that room.
I got into linguistics through a bug. Our school's reading app kept marking my cousin's Spanglish answers wrong, and I wanted to know why a program could read "I'm going to the tienda" but not understand it. Two summers of free online courses later, I'm still asking.
- What it does. One concrete question carries the whole answer, and the proof of interest is something the student did, not a claim of passion.
Saturday pancakes, my brother's bad jokes, the 4:15 bus being on time, a library card with no fines, and getting the last word in Scrabble.
- What it does. Five specific items, under the 50-word limit, that add up to a person. A list of virtues ("honesty, family, hard work") tells a reader nothing new.
How to write a why us essay that fits only one college
A why us essay proves two things at once: that you know what is different about this college, and that you need exactly that. Colleges say so in the prompt. Duke asks why it is "a good match for your goals, values, and interests", and UChicago asks you to "address with some specificity your own wishes and how they relate to UChicago" (Duke, UChicago).
Start with what you want
Write one sentence about what you hope to do in college, from something you have already done. That sentence decides which details about the college matter.
Find three specifics
Look on the college's own site for a course, a program, a research group or a tradition that serves that goal. Skip rankings, weather and anything every college has.
Tie each one to you
For every detail, add why you in particular would use it, ideally with a line from your past. A detail with no link to you is a brochure.
Run the swap test
Replace the college's name with a rival's. Any sentence that still reads true needs a more specific detail or should go.
Fit the limit
Columbia allows 150 words and Michigan's college essay up to 550, so one draft rarely fits two colleges. Cut to the limit with the essay shortener.
The wrong college name
Pasting a why us answer between colleges and missing one name is a common, avoidable error. The Common App final check looks for another college's name in each answer before you submit.
Reusing stories across colleges without repeating yourself
Most students apply to several colleges with similar prompts, and reusing a good story is normal. Every college reads its own file, so it's fine to send the same community story to Duke and Northwestern. Repeating a story within one application is the problem: each answer a college reads should show something new about you.
- Make a story bank first: eight to twelve moments, each with what it shows about you. The college application organizer has a page for it.
- Assign one story to each prompt at each college, and use each story once per application, counting your personal essay and activities list.
- Reuse community and academic answers freely, then rewrite the last two or three sentences for each college.
- Write a fresh why us answer for every college. Only the paragraph about you can carry over.
- Put context that fits no prompt, such as a school change or a grade dip, in the Common App's Additional information section, not in a supplement.
Before you paste an answer into another college's application
- The college's name, programs and places are the right ones throughout.
- The answer responds to this college's exact prompt, not a similar one.
- It fits this college's limit, in words or characters.
- It doesn't repeat a story from your personal essay or another answer to this college.
