In 2014, The Record writer Hannan Adely wrote that, since John F. Kennedy High School is an inner city school, it has faced problems of violence and other unmonitored hallway misbehavior from students. Accusations about mayhem at the school have come from not only its teachers and students but also representatives at the Paterson Education Association, including its former president, Peter Tirri,

On February 14, 2008, John F. Kennedy instructors and the Paterson Education Association filed a complaint against the school to the New Jersey Department of Labor and Workforce Development's Office of Public Employee Safety, citing lack of discipline on students using vulgar language towards personnel, physically assaulting teachers, urinating in non-bathroom areas, and protesting the school's schedules by pulling fire alarms. In 2014, Ted McNulty, a former metal shop teacher who retired from the school in July 2014, has expressed his testimonies through interviews by sources such as the talk show Chasing News and education reform news service Choice Media; and a book he wrote and self-published on January 11, 2017 titled RUINING a NATION and Nobody Cares. Superintendent officials have denied McNulty's claims.

In New Jersey Monthly magazine's yearly lists of the state's "Top Public High Schools," the school has been ranked 304th out of 328 schools in 2012, 290th out of 322 schools in 2010, 314th out of 316 schools in 2008, and 306th out of 316 schools in 2006.
