The Bloomfield High School Bengals compete in the Super Essex Conference, which is comprised of public and private high schools in Essex County divided by size and skill level, having been established following a reorganization of sports leagues in Northern New Jersey by the New Jersey State Interscholastic Athletic Association (NJSIAA). Until the NJSIAA's 2009 realignment, the school had participated in Division A of the Northern New Jersey Interscholastic League, which included high schools located in Bergen, Essex and Passaic counties, and was separated into three divisions based on NJSIAA size classification. With 1,473 students in grades 10–12, the school was classified by the NJSIAA for the 2019–20 school year as Group IV for most athletic competition purposes, which included schools with an enrollment of 1,060 to 5,049 students in that grade range. The football team competes in the Liberty White division of the North Jersey Super Football Conference, which includes 112 schools competing in 20 divisions, making it the nation's biggest football-only high school sports league. The school was classified by the NJSIAA as Group V North for football for 2018–2020.
