It is the fourth-oldest institution of higher education in the United States and one of the nine colonial colleges established before the American Revolution. The university moved to its current campus in 1756 and was renamed Princeton University in 1896.
Princeton offers undergraduate and graduate programs across various disciplines, including humanities, social sciences, natural sciences, and engineering, with approximately 8,500 students. It is known for its high research activity, particularly in fields such as physics, public policy, and finance.

Understanding Princeton’s Acceptance Rate
Princeton’s acceptance rate has remained below 6% for several years, making it one of the most selective universities in the United States.
Recent data shows:
- Class of 2027: 4.5% acceptance rate
- Class of 2026: 5.7% acceptance rate
- Class of 2025: 4.38% (a historic low)
The decline in acceptance rates coincides with a surge in applications, partly due to Princeton’s test-optional policy, introduced during the COVID-19 pandemic. Unlike some peer institutions (such as MIT and Harvard), Princeton has extended its test-optional policy through the 2025–26 academic year, leaving future applicants uncertain about long-term testing requirements.
Recent Admission Trends
- Record-high applications: The Class of 2025 saw a sharp increase in applicants, contributing to the lowest acceptance rate in Princeton’s history.
- Expansion plans: The university has been gradually increasing enrolment as part of a four-year expansion strategy, yet selectivity remains high.
- Impact of affirmative action ruling: The Supreme Court’s 2023 decision to strike down race-conscious admissions has influenced admission policies, though Princeton has not yet released detailed data on its effects.
