Almost every selective school asks a version of it. Why Penn, why Northwestern, why Michigan, why Tufts, why Rice. The prompt looks like the easiest thing on the application and it is where the most applications go quietly generic.
The reason is simple. Students write these last, at volume, in December, and the fastest way to fill 200 words about a school you have not researched is to praise it.
What is the “Why us” essay actually testing?
Whether you know what you applied to. That is close to the whole thing.
Admissions officers read thousands of these, and the ones that stand out are not the most enthusiastic. They are the ones that could only have been written by someone who opened the course catalog. Enthusiasm is cheap and every applicant has it. Specific knowledge of a program takes an hour and almost nobody spends it.
The name-swap test
Here is the only editing tool you need for this essay. Take your draft, replace every instance of the school name with a different school, and read it again. If it still makes sense, you have not written a Why us essay. You have written a description of college.
Most first drafts fail this test completely. Mine did. The sentences that survive it are the ones naming a course number, a specific requirement, a lab, a named program, a professor whose work you can actually describe. Everything that does not survive is filler, and you can cut it without losing anything.
How do you research a college without just reading the admissions page?
The admissions page is marketing, and every applicant reads it, so anything you find there is by definition not distinguishing. Go where the marketing is not.
- The course catalog. Find three courses you would actually take and read their descriptions, not just their titles.
- The degree requirements for your major. These tell you what the department believes matters, and they differ sharply between schools that look identical from the outside.
- Department pages and faculty listings. Not to name-drop a professor, but to find out what the department is oriented around.
- The student newspaper. This is the fastest way to learn what people there are actually arguing about.
- The club directory, if you can find one. It is usually more honest than the admissions page.
What should you never write in a “Why us” essay?
Rankings. Prestige. The weather. The beautiful campus. World-class faculty. The strong alumni network. The line about how you visited and immediately felt at home. None of these are wrong, exactly, and all of them are true of a hundred schools, which is the problem. They also signal the thing you least want to signal, which is that you ran out of research.
One more: do not write about a program you are not applying to. If you applied to engineering, an essay about the creative writing department reads as a mistake rather than as range.
Why does Cornell ask a different question?
Because at Cornell you are not applying to Cornell. You are applying to one of its undergraduate colleges, and they are genuinely different institutions with different requirements, different cultures, and separate admissions. Arts and Sciences, Engineering, the Dyson School, the School of Industrial and Labor Relations, Human Ecology, and Agriculture and Life Sciences all read their own applicants.
Cornell asks you to write to the specific college, and an essay about Cornell in general is a weak answer to that question. Penn works similarly, asking you to address the specific undergraduate school. Michigan wants to know about the college within the university. If a school splits itself this way, that split is the subject of the essay.
How long should the essay be?
Anywhere from about 100 words to 650 depending on the school, and the short ones are harder. A 150 word limit means you get roughly three sentences of substance, so every sentence has to carry a specific fact. There is no room for an introduction. Start with the thing itself.
Word limits move between cycles, so check each school rather than trusting a chart.
Can you reuse one supplement across several schools?
You can reuse the structure. You cannot reuse the content, and the attempt is visible from a long way off.
What travels between schools is the half about you: what you want to study, why, and what you have already done about it. That part is stable and you should write it once and write it well. What has to be rebuilt every time is the half about them, the courses and requirements and programs that make this school a specific answer to that specific want. Roughly speaking the ratio should land near half and half, and the two halves have to actually touch. An essay that spends 100 words on you and 100 words on them without connecting the two is the most common failure mode after generic praise.
Does the “Why us” essay matter more for Early Decision?
In practice, yes. Applying Early Decision is a binding statement that this school is your first choice, and a vague Why us essay sitting inside a binding application is an odd combination that readers notice. If you cannot fill 300 specific words about a school you have committed to attend, that is worth knowing before you commit.
Note that this cuts the other way at the UCs, which do not have a Why us essay at all and do not consider demonstrated interest. If California schools are on your list, the Personal Insight Questions work on completely different rules.
How does the Narrative Method apply to supplements?
Supplements are where a throughline either proves itself or falls apart. If you know what your application is about, the Why us essay writes itself into that shape: here is what I am trying to do, here is the specific machinery at your school for doing it. If you do not, you end up writing a fresh argument for every school and none of them connect to your main essay.
That is the real cost of leaving supplements until December. Not the writing time, the fact that you are making up your reasons school by school. The Narrative Method exists to stop that.
Have a list of ten schools and ten supplements to write? Apply for mentorship and we will build the throughline first, so the supplements get easier instead of harder.
