Rosemont High School, one of the district's newest schools, is located along Kiefer Boulevard in the heart of Rosemont. The school focuses on preparing students for life after graduation, and requires each student to enter a freshman academy and then choose one of six small learning communities. Each is centered on an area of study, a trade or public service.
The school opened with a freshman class in portable classrooms in 2003, and its main facility was completed in 2004. Rosemont High School's principal is Leise Martinez.
