What is does college have prom?

No, colleges generally do not have proms. Prom is a tradition typically associated with high schools in the United States and some other countries. College students often have their own social events and formal dances, but they are usually called something different, such as a "formal," "gala," or "dance." These events are organized by student organizations, fraternities, sororities, or the college itself and are not usually referred to as "proms."
