What should you write your college essay about?

SStanford's admissions committee once denied a valedictorian with a near-perfect transcript over a single page of the application, the personal essay. A reader there had opened his file: he came from one of the strongest high schools in the country, with nearly all A's in the hardest courses, warm letters, serious activities, and scores exactly where they needed to be. The committee denied him, and the reason, as the reader later told it, was the essay. He had written about breaking up with his girlfriend.

This account raises a question about the essay's purpose, beyond whether the topic was tasteful or the sentences were polished: what did the reader learn about the student?

Considering the academic audience for your college essay

A university admits students to read, argue, write and research alongside professors, people who loved school so much they arranged never to leave it. At most selective universities, professors don't choose their own students. Admissions officers choose for them. Ask that client what it wants, as Stanford's readers did, and the answer hardly changes: find me the most intellectually alive students you can, ideally ones already obsessed with my field.

Against that brief, the verdict stops looking harsh. The breakup mattered to him, and it gave the faculty nothing to want. Somewhere in the same stack sat a student with the same grades who had become so absorbed in the Nicomachean Ethics that she taught herself ancient Greek to read the rest of Aristotle in the original. When two files are equal on paper, the essay decides which student the philosophy department would rather teach.

The trait has a name

Stanford's readers called it intellectual vitality: academic energy you can feel on the page, whether it shows as raw intelligence, as visible delight in learning, or as thinking careful enough to stop a tired reader mid-paragraph. Grades show a reader that you did the work you were given. Vitality shows them what you do when nobody gives you anything.

The story can be small. The thinking has to be large.

What this changes on the page

The Common App calls the long essay "personal," and students hear "private." To the people deciding, the most personal thing about you is how your mind works. So we ask every student to write about what they hope to study, or about the habit of mind that will make them good at it. A future economist might write about why her family's restaurant changes its prices on Tuesdays. A grandmother, a job or a move still belongs in the essay, as evidence of how you think.
