What it is

A piece of your scholarly writing submitted as evidence of your research and writing capability. For PhD programs especially in humanities, social sciences, and CS theory, the writing sample is one of the most weighted parts of the application.

Why it matters

Faculty want concrete evidence you can reason at the level required for graduate study. The CV says you wrote things; the writing sample lets them read your thinking directly.

How to get it

  1. 1

    Identify your strongest piece of academic writing. Best options in order: a published paper → a long-form thesis chapter → a graded final paper for a relevant course.

  2. 2

    Confirm length requirements per program. Most ask 10-25 pages; some cap at 15.

  3. 3

    Edit ruthlessly for clarity. Submit the strongest, tightest version — not your longest.

  4. 4

    If submitting a thesis chapter, include a 1-paragraph framing note ("This is Chapter 3 of my undergraduate thesis on X; full thesis available on request").

  5. 5

    Submit as a clean, paginated PDF with a clear title page.

Tips & best practices

  • Quality > length. A tight 12-page paper beats a sprawling 25-page one.
  • Submit work in or close to the field you want to study. A philosophy writing sample for a CS PhD application is a poor fit.
  • For applicants without a long thesis or published paper: a strong term paper (graded A or A+) with the professor's comments addressed in your revision is acceptable.

Common mistakes to avoid

  • Submitting a paper in a totally different field. Even brilliant writing in the wrong subject doesn't help much.
  • Submitting raw, ungroomed coursework with red-ink comments still visible.
  • Going over the page limit. Reviewers will stop reading at the cap.
