The John Jay College of Criminal Justice is a senior college of the City University of New York in midtown, Manhattan, New York City and is the only liberal arts college with a criminal justice focus in the United States. It has about 14,000 FTE (full-time equivalent) students, including traditional, pre-career undergraduate students and those pursuing master’s degrees in several disciplines. John Jay College of Criminal Justice was founded in 1964 and was originally called the College of Police Science (COPS). Classes were held at the Police Academy on East 20th Street. Eventually, the school was expanded to incorporate many liberal arts disciplines and was renamed John Jay College of Criminal Justice.
It moved to its current location in the former Charles B. J. Snyder-designed De Witt Clinton High School in 1988. After Clinton moved to the Bronx the building became Haaren High School. The building is now Haaren Hall on the campus.
Internationally recognized as a leader in criminal justice education and research, it is also a major training facility for local, state, and federal law enforcement personnel. The college regularly invites distinguished speakers such as Janet Reno and Supreme Court Justice Ruth Bader Ginsburg.
The school's namesake, John Jay, was the first chief justice of the United States Supreme Court and one of the founding fathers of the United States. Jay was a native of New York City, and a New York State governor.
The school also boasts a Forensic Science program, one of the few schools in the nation which offers the undergraduate degree.
The campus consists of five buildings: Haaren Hall (also known as the Tenth Avenue building or, simply, the T building), which also contains the Lloyd George Sealy Library, gym and pool; North Hall (N building); newly constructed Westport Building (W building) where John Jay College rents the first two floors; one floor of the BMW building (6th floor) and one floor of 619 West 54th Street (54th St Annex). Administration offices are on the top floor of the T building, while the departmental offices are spread across the N building with the exceptions of Foreign Language and English, which are now located on 54th Street.
The college also has a student government consisting of the Student Council, the Judicial Board, and various student organizations known collectively as "Clubs". On April 1, 2008, the student body ratified amendments to the Charter of the Student Government via a referendum during the annual Student Government elections--something that has not been attempted in nearly 30 years. These amendments were authored by the Student Council's 37th president, Francis J. Balducci, and were ratified by the members of the 2007-2008 Student Council.
"Club Row" is the nickname in the college for a series of hallways where the student clubs are given space. Student organizations that are given the title "Essential Service" by the City University of New York include The John Jay Times, the school's theater group known as the "John Jay Players", and the campus radio station known as WJJC.
The school is working on a project known as "Phase II", which involves the construction of an additional building on 11th Avenue between West 58th and West 59th Streets in New York City. It is anticipated that construction will be completed by 2012 at which time the N building will be relinquished to the State of New York.
JJC does not have its own dorms and is considered a "commuter college" as most students still live at home. Ninety-three percent of JJC students are in-state students. Many graduate students come from out of state and often live in the City College dorm called the Towers at City College.
