 The Elmwood Park High School Crusaders compete in the North Jersey Interscholastic Conference (NJIC), made up of private and public high schools located in Bergen County, Hudson County and Passaic County, following a reorganization of sports leagues in Northern New Jersey by the New Jersey State Interscholastic Athletic Association (NJSIAA).With 533 students in grades 10–12, the school was classified by the NJSIAA for the 2015-16 school year as North I, Group II for most athletic competition purposes, which included schools with an enrollment of 495 to 762 students in that grade range.Prior to realignment that took effect in the fall of 2010, Elmwood Park was a member of the smaller Bergen-Passaic Scholastic League (BPSL).
