Welcome to the heart of Grand Valley State University, the College of Liberal Arts and Sciences! CLAS is the largest of Grand Valley's colleges. Our students choose from more than 50 bachelor degrees (and a growing number of advanced degrees) in the natural and mathematical sciences, the fine arts and humanities, and the social sciences. In fact, all GVSU undergraduates build the foundation for their major studies in general education courses offered by our College. It all starts here.
