Reading the Common Data Set to Find Real Admit Rates, Merit Aid, and Test Score Ranges
By Muntasir • Published May 28, 2026 • Updated Aug 08, 2026 • Guides
The Common Data Set is a free standardized report most colleges publish every year with unfiltered numbers on admit rate, test score ranges, and merit aid, straight from the registrar rather than the marketing office. Find one by searching the college's name plus "common data set" and the year.
🎓 Section C covers admission stats: applicants, admits, enrolled, and the middle 50% test score range
Section H covers financial aid, including the percent of students without need who got merit aid
The same section numbers line up across every school's report, so comparisons are apples to apples
Search "[college name] common data set [year]" to find the PDF, or check the school's institutional research page
Data comes straight from each college's own office of institutional research, not admissions marketing copy
What the Common Data Set is
The Common Data Set (CDS) is a standardized survey format developed jointly by the College Board, Peterson's, and U.S. News and World Report, described at commondataset.org . Most four-year colleges fill out the same set of numbered questions every year and publish the results, usually as a PDF on their institutional research or planning office page. Because every school answers the same fields in the same format, you can pull identical categories across schools and compare them directly, instead of relying on each admissions office's own marketing language.
How to find a school's CDS
Search the college name plus "common data set" and the most recent academic year, for example "common data set 2025-2026."
If the PDF does not appear in search results, look for the school's office of institutional research, institutional effectiveness, or planning and assessment page, where CDS files are usually archived by year.
If neither works, email the institutional research office directly and ask for the most recent CDS filing. Public colleges in particular are used to this request.
What each section tells you
The CDS breaks the college into lettered sections. The ones worth checking first are:
| Section | What it covers |
|---|---|
| B | Enrollment and first-year student retention rate |
| C | First-time, first-year admission: applicants, admits, enrolled, and test score ranges |
| H | Financial aid, including merit aid to students without financial need |
Reading admit rate and test scores correctly (Section C)
Section C shows the raw count of applicants, admits, and enrolled first-year students, which lets you calculate the real admit rate yourself rather than trust a rounded number from a ranking site. It also lists the 25th and 75th percentile SAT and ACT scores among admitted, enrolled students. That middle 50% range tells you more about where you realistically fit than a single "average" score, since half of enrolled students scored outside that range in either direction.
Reading merit aid data (Section H)
Section H separates need-based aid from merit aid. Look for the line showing the percentage of students without financial need who still received a non-need-based (merit) scholarship, along with the average award amount for that group. A school that reports a high percentage of non-need students receiving merit aid is more likely to offer you a scholarship even if your family does not qualify for need-based grants.
Where the CDS differs from a college's own website
Admissions marketing pages tend to show the most favorable framing of a number. A website might publicize the test score range for admitted students overall, while the CDS breaks out enrolled students specifically in Section C, a figure that often runs lower since students with the highest scores frequently enroll elsewhere after being admitted to several schools. Because the CDS format is standardized across colleges, there is far less room to cherry-pick a flattering subgroup than on a page written by an admissions marketing team.
The same standardization applies to merit aid. A college's financial aid page might highlight its single largest scholarship, while the CDS reports the actual share of non-need students who received any merit award and the average dollar amount across that whole group, a more honest picture of your real odds.
What to do if a school doesn't publish a CDS
Not every college, particularly some smaller private and for-profit schools, publishes a CDS. If you cannot find one after checking the institutional research page and emailing the office directly, fall back on NCES College Navigator , which pulls the same underlying IPEDS data every Title IV school must report, including admissions statistics, retention, and financial aid figures.
Common mistakes when reading a CDS
Comparing an old CDS filing for one school against a current filing for another. Always check the academic year printed at the top of each document before comparing numbers.
Reading the overall admit rate without checking if the school also reports separate rates for early decision, early action, and regular decision, which sometimes differ by a wide margin within Section C.
Treating the middle 50% test score range as scores needed for admission, when it actually reflects the range among students who were both admitted and chose to enroll, a narrower group than all admits.
Skipping Section B, which shows the actual first-to-second-year retention rate, a number that says more about whether students are satisfied once enrolled than admissions statistics alone.
Using CDS numbers across schools
Because every school files the same lettered sections, build a simple spreadsheet with the same fields side by side for each college on your list: admit rate, middle 50% test scores, retention rate, and merit aid percentage. Pulling three years of a single school's CDS filings also shows whether admit rate and merit aid patterns are trending up or down. For national context on how admissions offices weigh these numbers, the National Association for College Admission Counseling publishes an annual State of College Admission report.
