Prospect Heights High School, formerly The Girls' Commercial High School, is a defunct comprehensive high school that served the Prospect Heights neighborhood of Brooklyn, New York City from the 1920s to 2006. Prospect Heights Campus is the collection of educational buildings that housed Prospect Heights High School until its closure in 2006. Despite its name, the school was south of Eastern Parkway, the commonly accepted southern border of the Prospect Heights. History The Girls' Commercial High School, later to become Prospect Heights High School, was built in the 1920s. The school's exterior was designed to harmonize with the environment, while the interior was made to accommodate 3,500 students in fifty regular classrooms and other specialized laboratories and working rooms. Around 1947, it was renamed Prospect Heights High School as the curriculum encompassed college preparatory academic courses as well as those in fine arts and fashion along with the traditional commercial course. Later the all-girls high school became coeducational. After many years of decline and falling academic levels, the school graduated its last class in June 2006 and was closed. The Prospect Heights building now houses four small high schools: the Brooklyn School for Music and Theater, Brooklyn Academy for Science and the Environment, International High School at Prospect Heights, and the High School for Global Citizenship. The main reasons for Prospect Heights High school's closure were overcrowding and consistently low performance grades received from the New York City Department of Education. The building was broken down into four smaller high schools, each with a specific focus and a cap on students. Violence was also an issue within Prospect Heights High School. Its neighborhood saw a rise in gang activities in the 1980s, which seeped into the school and caused problems. Prospect Heights High School was ranked the twelfth most violent high school among New York City's 125 high schools in 1990 by the Board of Education, and became an example used by advocates for more metal detectors in New York City schools. Recently police involvement in the neighborhood has reduced the violence.
