How to Find Colleges With Small Class Sizes

Many students say they want small classes. They imagine a seminar table where the professor knows their name, rather than a lecture hall of several hundred people. That is a reasonable goal, but the claim "small class sizes" appears in almost every college brochure, and the numbers behind it vary a lot.

This guide shows you how to look past the slogan, where to find real figures and how to get a small-class experience even at a larger school.

What "small" means in practice

There is no official definition, but these bands are a useful guide:

What matters is not the school's average but the mix of classes you will take. A student who spends two years in intro courses of 200 and two years in majors of 15 has a different experience from one in classes of 25 throughout.

Student-faculty ratio is not class size

Rankings and brochures often highlight the student-faculty ratio, such as 10 to 1. It sounds like a promise of small classes, but it is only the number of students divided by the number of faculty. It includes faculty who mostly do research, teach graduate courses or have small sections, so the ratio can be low while undergraduates still sit in large lectures.

If you want to know about classes you will attend, look for the distribution of class sizes instead.

Where to find real data

The Common Data Set

Many US colleges publish a Common Data Set, a standard report in a fixed format. Section I-3 lists the number of class sections in each size band for undergraduate courses, along with the number of subsections such as labs and discussion groups. Search the college's name plus "Common Data Set" to find it, usually on the institutional research page. Our glossary explains the Common Data Set in more detail.

How to read it:

1. Add the totals for the smaller bands, such as 2 to 9 and 10 to 19.
2. Compare them with the total sections to see the share that are small.
3. Check the bands for 50 and above to see how many large classes there are.
4. Compare two or three schools in the same way, using the same year.

The school's own pages

Some schools post average class size, or the share of classes under 20, on their admissions or fact pages. Treat the figure as a starting point and check the definition. Some exclude labs, discussion sections or graduate courses, and some count only certain years.

Course schedules

For a real picture, open the online course search for the next term and look at the enrollment limits for the courses in the major you are considering. Seeing "cap 18" or "cap 250" tells you more than a brochure.

Outside the US

In the UK, universities often describe teaching in lectures, seminars and tutorials. Seminar groups are usually 10 to 20 students, and Oxford and Cambridge use very small tutorials. In Canada, some universities publish class size distributions, and Maclean's separates primarily undergraduate universities, which tend to be smaller. Ask each school for typical group sizes for your course.

Which kinds of schools tend to have small classes

Large public research universities usually have big introductory lectures, but their upper-level classes and labs can be small. See our guide to liberal arts colleges for one common route.

Questions to ask on a visit or call

Class size is easy to ask about, and the answers show whether the claim is real.

• What share of first-year classes have fewer than 20 students?
• Who teaches introductory courses, professors or graduate assistants?
• Are there discussion sections, and how big are they?
• How large are classes in my intended major in the third and fourth years?
• Does the honors program have its own small sections?
• Are there first-year seminars?
• How easy is it to get into the small classes? Are they capped and do they fill early?

What small classes give you

• More feedback. Instructors can read your work and comment in detail.
• More chances to speak. Participation often counts toward the grade.
• Easier relationships. Letters of recommendation and research invitations are more natural when a professor knows your work.
• Accountability. It is harder to hide, which helps some students and stresses others.

They also have costs. A small school may offer fewer majors, narrower electives and fewer advanced facilities, and a poor match with an instructor is more noticeable.

Getting small classes at a larger school

You can create a small-class experience wherever you study.

1. Apply to an honors program at your university, which often offers seminars and priority registration.
2. Choose seminars and upper-level courses early in your degree, not only large lectures.
3. Use discussion sections and labs, where groups are smaller.
4. Go to office hours. One-to-one time makes a large class feel smaller.
5. Join research projects, learning communities or clubs in your department.
6. Register as early as you can, because small courses fill quickly.

Warning signs in marketing

• A class size figure with no definition or year.
• A student-faculty ratio presented as if it were class size.
• "Average class size" without the share of very large classes. Averages hide a few huge lectures.
• Photos of seminars as the main image while the data shows mostly lectures.
• A refusal to give figures when asked.

How much does it matter?

For many students, a few large first-year classes are fine, especially when upper-level courses are smaller. If you need close feedback, struggle to speak up in big rooms or want to build relationships with faculty, small classes can be worth paying for. If you value variety, research facilities or a large community, a bigger school may suit you better even with some big lectures.

A simple scoring method

If you are comparing three or four schools, a short scorecard keeps the process fair. For each school record the following and compare them side by side.

Give each school a score from one to five on each row, then add the totals. The result will not decide your choice, but it shows whether the small-class claim holds up.

Questions about fit

Small classes suit some students more than others. If you like to think aloud, want detailed feedback and enjoy knowing your classmates, they can be a big advantage. If you prefer to listen first, enjoy anonymity or want the widest range of courses, a mix of large and small may be better. Think about how you learn best in a class today and how you would feel if every course expected you to speak in every session.

The bottom line

"Small class sizes" is a claim you can test. Look at the Common Data Set or class size bands, ignore the student-faculty ratio as a proxy, check the actual course caps in your major and ask direct questions on a visit. If the numbers do not match the pitch, you have learned something important before you commit.
