The school opened in 1973. In 2009 Penn had 633 students. That year, the school district proposed closing Penn, because its declining enrollment was far below the building capacity and because the building was in poor condition. The district proposed rezoning Penn zone residents who were also in the Clymer School zone to
Simon Gratz High School, and it proposed rezoning Penn zoned residents who were also in the zones of Dunbar, Ferguson, Harrison, and Hartranft to
Benjamin Franklin High School. Some individuals opposed to the closing argued that if Penn was closed and its students were moved to Franklin, students would engage in "turf warfare" and the abandoned school building would become a haven for criminal activity. The closing was approved. In February 2015 the Philadelphia City Planning Commission approved the demolition of the school. Demolition began in December 2015, with demolition of the campus's east side scheduled to end in February of the following year, Temple planned to install an athletic center on the east side. Athletic activities were scheduled to begin on the former Penn site in October 2016. ==Campus==
