Our goal is to make online education work for everyone.

Class Central is a listing of online courses. We aggregate courses from many providers to make it easy to find the best courses on almost any subject, wherever they exist. Whatever you are interested in learning, it is more than likely that our catalog includes a course that will meet your needs.

Through Class Central, you can find courses; review courses you’ve taken (and read other people’s reviews); follow universities, subjects and courses to receive personalized updates; and also plan and track your learning.

Community driven

Class Central is a remote company with no physical offices. Our team consists of learners whose lives have been impacted by online education. Between us, we have done 400+ online courses and 3 online degrees. If our names look familiar, it may be because you have read articles we have written or even because one of us has been a mentor in a course you took.

Our goal is to make online education work for everyone, so we’re constantly working on new features. If you have an idea for how to make Class Central more useful, please let us know.

The Report

We are in the business of educating people about education. In addition to our catalog, The Report by Class Central keeps tabs on the overall state of the online education landscape. We especially like to uncover overlooked stories and ascertain trends that others haven’t yet reported.

How do we make money?

Class Central makes money through advertising and affiliate links. We’ve tried to clearly denote ads and sponsored search results. We stand to earn a commission when someone clicks through to a course provider and upgrades to a paid offering. For a substantial portion of our catalog we do not have any affiliate partnerships. Our affiliate and advertising relationships don’t influence the course listing, nor do they affect user reviews. The most important thing to us is to maintain a relationship of trust with our users, so we want to be transparent about how the bills get paid.
