[3][4][5][6] While serving in New Jersey General Assembly from 1964 to 1972, Kenneth T. Wilson was also employed as a teacher at East Orange High School, where he taught civics and American history.

[8] In 1896, East Orange was one of the founding member schools of the New Jersey Interscholastic Athletic Association, the state's first athletic conference; created and operated by students, the conference consisted of nine public and private high schools located across the state, competing in track and field, football and tennis.

[9] Begun in 1897, East Orange had an annual Thanksgiving Day football rivalry with Barringer High School that had been the nation's longest-running continuous rivalry, played for 91 consecutive years until 2006, when scheduling conflicts interfered with the annual tradition; traditionally, the Left-Footed Kicker trophy is awarded to the winning team, with games attracting as many as 13,000 fans until the 1970s, when both teams saw their football programs deteriorate.

[10] In March 1930, Gordon Chalmers won the title in the 100-yard backstroke at the national interscholastic aquatic champions at Columbia University, leading East Orange High School to a second-place team finish.

[12] The girls' basketball team won the Group IV state championship in 1980 vs. Atlantic City High School.
