Why prom is held in a school?

Prom is held in a school to celebrate the culmination of high school experiences and foster a sense of community among students. It provides an opportunity for students to socialize, create lasting memories, and mark the transition to adulthood. Hosting prom at the school also keeps the event accessible and familiar, allowing students to enjoy the festivities in a safe environment. Additionally, it highlights the school's role in shaping students' social experiences during their formative years.
