Princeton University Paper Format & Writing Requirements

Princeton University at a glance

The undergraduate-focused Ivy famous for the required junior paper (JP) and senior thesis — every student does original research twice.

The campus sits in Princeton, New Jersey, operates as a private (ivy) institution, and enrolls about 9,000 students — a scale that directly shapes how writing support works. Founded in 1746 with an acceptance rate around 4%, Princeton University pairs selective admissions with the large-course writing loads typical of its category.

Citation styles Princeton University actually requires

Princeton University courses predominantly require Chicago or MLA 9 or APA 7. That is not a trivial preference: it decides your title page, heading levels, in-text punctuation and reference format on every graded document.

• Chicago: used across history, fine arts and some social science seminars
• MLA 9: used across humanities and writing-sequence courses
• APA 7: used across social science, nursing and business courses

Verify against the specific course syllabus anyway — instructors can override departmental defaults, and the first paper is where they enforce it.

The writing requirement, decoded

The Writing Seminar (WRI) requirement plus departmental JP and senior thesis requirements.

Plan the sequence early: composition requirements compound, and students who defer them discover the advanced seminars — where the writing-intensity lives — conflict with major courses later. The registrar's degree audit shows exactly which flags remain; check it each semester.

Three things about Princeton University papers that surprise new students

• Every Princeton senior completes a thesis — from SPIA policy analysis to studio art.
• The junior paper (JP) is a dress rehearsal: graded, defended and often later published.
• WRI seminars' topics are published as a catalog; 'Crime & Punishment in America' recurs annually.

None of these appear in the course description. All of them appear in the rubric. Students who learn them in week one report smoother first-semesters than students who meet them at the deadline.
