How to Read a College's Common Data Set Before You Apply: A Class of 2027 Guide

Most families compare colleges by sticker price and a few glossy brochures. There is a free document that tells you much more, and almost nobody reads it: the Common Data Set. If your student is in the Class of 2027 and building a Fall 2027 college list right now, spending 20 minutes with this document can show you which schools tend to give real grant money and which ones tend to hand out loans and hope. This guide walks you through exactly where to look and what the numbers can and cannot tell you.

What Is the Common Data Set, and Why Should Families Care?

The Common Data Set (often shortened to CDS) is a standard set of questions that colleges answer about themselves each year. It started as a joint effort among data providers in higher education and several publishers, including the College Board, Peterson's, and U.S. News & World Report. Old Dominion University's explanation says the goal is to "improve the quality and accuracy of information provided to all involved in a student's transition into higher education" while reducing the reporting burden on colleges.

Because every school answers the same questions with the same definitions, you can put two colleges side by side. That is rare. Award letters look different at every school, and websites tell you what each college wants you to see. The CDS is closer to an apples-to-apples report card.

Many colleges do not post a CDS publicly, and the ones that do post it in different places. That is not a red flag by itself. It just means you may need to ask.

Where to Find a College's Common Data Set

Try these steps in order:

• Search the college's name plus "Common Data Set" in your browser.
• Look on the college's institutional research or "institutional effectiveness" web page, which is where many schools store it.
• Check the admissions or financial aid pages for a link to "facts and figures."
• If you cannot find it, email the admissions office and ask where to find the most recent Common Data Set.

Pick the newest year available, and note the year printed on the file. A college may post a document that is one or two years old, so treat the numbers as a recent pattern rather than a promise about next year.

Start With Section H: The Financial Aid Numbers

Section H is the financial aid section, and it is the part most useful to a family trying to figure out cost. Here is how one recent college's Section H is organized, using Geneseo's 2023-2024 file as an example. The same layout shows up at many schools.

The "Need Met" Rows

A table near the top of Section H counts students in three groups: first-time full-time freshmen, all full-time undergraduates, and less-than-full-time undergraduates. For each group, the rows work like a funnel. They count students who applied for need-based aid, students who had financial need, and students who received any aid. Further down, the table shows:

• How many students had their need fully met.
• The average percent of need that was met.
• The average total aid package.
• The average need-based scholarship or grant.
• The average need-based self-help, which means loans and work-study.

Start with the first-time full-time freshmen column. That is the group your student will join.

"Need" here means the cost of attendance minus what the family is expected to contribute, based on that college's own method. "Need met" means how much of that gap the college's package covered, and it counts loans and work-study as part of the package. The Geneseo file also notes that PLUS loans, unsubsidized loans, and private loans are left out of the need-met and self-help calculations.

The Average Package: Grants Versus Loans

A high "percent of need met" sounds great. Do not stop there. Look at the average need-based grant and the average need-based self-help line right below it. Grants and scholarships are money you do not repay. Self-help is loans and work, which you do repay or earn.

Two colleges can both say they meet most of need and still leave a family with very different bills.

Merit Aid for Students With No Need

A second table, often labeled H2A, covers non-need-based scholarships and grants. It shows how many students with no financial need received institutional aid and the average amount. If your family does not expect to qualify for need-based aid but you are hoping for a merit scholarship, this is the table to read. It also helps you spot schools where merit awards are common and large versus rare and small. For more on how schools set these discounts, see our guide on how institutional merit aid works.

A Worked Example With Made-Up Numbers

These numbers are invented to show the idea. They do not describe any real college.

Say a family has $30,000 of demonstrated need at two colleges.

• College A reports that it meets 100% of need on average, with an average need-based grant of $16,000. The other $14,000 is loans and work.
• College B reports that it meets 85% of need on average, with an average need-based grant of $21,000. That leaves $4,500 in loans and work and $4,500 of unmet need.

College A sounds more generous. But after grants, the family at College A has $14,000 to cover through loans and work. At College B, the same family has $9,000 left to cover ($4,500 in self-help plus $4,500 in unmet need). This is one reason grant dollars matter more than the headline percentage.

These are averages across many students, so your own package can land above or below them.

What Section H Cannot Tell You

The Common Data Set is a useful starting point, and it has limits. Keep these in mind:

• It reports enrolled students. The numbers describe students who chose to enroll, not everyone who was admitted. Students who got weak offers may have gone elsewhere.
• It shows averages. A family with very high need may see a very different package from the average.
• It uses the college's own definition of need. One school's "need" is not identical to another's.
• It is a year or more old. Policies can change, especially at colleges that adjust their aid budgets.
• It does not break out income. The CDS does not tell you what a family at your income level pays.

To close that last gap, run each college's net price calculator and compare the results. You can also look up a college's average net price by income range on the federal College Navigator tool. Our guide to using award letters to decide between colleges shows how to compare real offers once they arrive.

Check the Policy Rows: Forms, Deadlines, and Award Criteria

Further down Section H are questions about process rather than totals. These are easy to skim and can save you from a missed deadline:

• H8 lists which forms first-year applicants must submit, such as the FAFSA, the CSS Profile, or a state or institutional form.
• H9 and H10 list priority and filing deadlines, plus when students are notified.
• H12 lists the factors a college uses when awarding its own aid, such as academics, leadership, or athletics.

If a college requires the CSS Profile, read our 2027-28 CSS Profile checklist. Then confirm any date you plan to rely on on the college's current financial aid page, because the CDS may be a year old. We also built a calendar of regular decision financial aid deadlines for the Class of 2027 to help you line these up.

Other Sections Worth a Quick Look

You do not need to read the whole document. These parts add helpful context for a cost-focused family:

• Admissions (Section C): how many students applied, were admitted, and enrolled. Many colleges also report early decision and early action numbers here.
• Enrollment and persistence (Section B): graduation and retention rates. A school that gives a generous first-year package but loses many students before year two may not be a good value. Our resource on retention rate explains why.
• Transfer admission (Section D): useful if a student plans to transfer later.
• Expenses (Section G): the published tuition, fees, and room and board.

A 20-Minute Routine for Your College List

Here is a simple plan you can follow this month for a list of six to eight schools. Use a spreadsheet or a sheet of paper with one row per college.

1. Find each school's most recent Common Data Set and write down its year.
2. In Section H, copy the percent of need met, the average need-based grant, the average self-help amount, and the number of students whose need was fully met, all from the first-time full-time freshmen column.
3. If you do not expect need-based aid, copy the H2A merit numbers instead.
4. Write down the forms and deadlines from H8 to H10.
5. Rank the schools by average grant, not by percent of need met.
6. Run each school's net price calculator and compare the results to your notes.

If you want to organize the results alongside your other options, you can create your free CollegeLens plan and keep your net cost comparisons in one place. To check how affordable colleges in your state are for low- and moderate-income families, read our summary of the NCAN affordability report.

If You Are Starting in Spring 2027 or Transferring

The CDS tables for aid focus mostly on first-time freshmen and all full-time undergraduates. If you plan to start in January or transfer in, the numbers are still helpful as a general signal of how a college treats aid. But your own package will depend on your situation, so call the financial aid office and ask how aid works for spring starters or transfers. Spring 2027 starters can still use the 2026-27 FAFSA, and our Spring 2027 aid guide covers the details.

Questions to Ask After You Read It

The Common Data Set often raises good questions. Consider asking the financial aid office:

• Is the average need-based grant in your Common Data Set typical for a student like me?
• Does your school meet full need for students admitted in early decision and regular decision alike?
• Do merit scholarships renew automatically, and what GPA is required?
• How often do your aid policies change from one year to the next?

Asking is not rude. Aid offices answer these questions all the time, and a clear answer tells you a lot about how the school treats families.

The Bottom Line

The Common Data Set will not give you your own price. It can help you tell which colleges on your list lean on grants and which lean on loans, and it can do that before you spend application fees or a campus visit. Read Section H first, compare grant dollars rather than headline percentages, confirm deadlines on each college's current page, and then use net price calculators to see what your own family might pay. Paying for college is stressful, and small steps like this one can make the decision feel more manageable.
