What United States universities are on the semester system?

The vast majority of universities in the United States operate on either a semester or quarter system. There isn't a readily available, comprehensive list of *only* those on the semester system because it's the more common arrangement. To find out if a specific university uses semesters, you'd need to check its academic calendar on its official website.

However, it's easier to identify universities that are *not* on the semester system (i.e., those on the quarter system or trimester system), as those are less frequent. Many prominent universities in the US are on the semester system, including most of the Ivy League schools and large public universities.

To find out if a *specific* university uses semesters, go to its website and look for an "Academics," "Calendar," or "Registrar" section. Their academic calendar will clearly state whether they use semesters, quarters, or another system.
