History
Hillside High School on Liberty Avenue was originally constructed in 1939–40 with the first graduating class in 1941, replacing the Coe Avenue School which became a grammar school. Additions were later added to accommodate the baby-boomers of the 1950s and 1960s. In the mid-sixties the high school held some 1,500 students.
Athletics
The Hillside High School Comets compete in the Union County Interscholastic Athletic Conference, which consists of public and private high schools in Union County and operates under the New Jersey State Interscholastic Athletic Association. With 658 students in grades 10-12, the school was classified by the NJSIAA for the 2015-16 school year as Central Jersey, Group II for most athletic competition purposes, which included schools with an enrollment of 498 to 750 students in that grade range. Before the 2010 realignment, the school had participated in the Mountain Valley Conference, which consisted of public and parochial high schools in Union County, Essex County and Somerset County. In 1986, the Hillside Comets football team finished with an 11–1 record and a North II Group II state championship with a win against Madison High School. After knocking off the second and third seed in the first two rounds, the seventh-seeded Hillside team won its second North II Group II state sectional championship with a 20-13 win at High Point Solutions Stadium against top-seeded and previously undefeated Point Pleasant Borough High School in the final game of the 2017 tournament playoff. The boys' basketball team won the Group II state championships in both 1990 and 1992, defeating Middle Township High School in the tournament final in both years. In 2011, the Hillside High School cheerleading team, under coach Keyla Silva, won the title of State Champions at the NJCDCA competition in Trenton in the Intermediate Varsity division. After this victory the cheerleaders held this title for three years in a row, repeating as state division champion in 2012 and 2013.
