The Common Data Set is published annually by every accredited US college and contains standardised admissions, enrollment, and financial aid data. It is the single most reliable source of college statistics and is freely available online — but most students have never heard of it. This guide shows exactly which sections to use and how to extract the numbers that matter most for your college research.

How to Use the Common Data Set for College Research in 2026

The Common Data Set is a standardised annual publication from every accredited US college. It is produced through a cooperative agreement between College Board, Peterson's, and US News. Because every school uses the same format, you can compare data across schools on equal terms. Find it by searching '[School Name] Common Data Set 2024' — the most recent complete cycle is typically published by spring of the following year.
