High-school balls, also known as proms, are formal dances held by high schools in the United States and Canada. They are typically held at the end of the school year and are attended by students in their junior or senior year. Proms are usually organized by the school's student council and involve a variety of activities such as dinner, dancing, and entertainment. The event is often seen as a rite of passage for high school students and is an important part of the high school experience.
