History Students from Butler had been sent to attend high school in Paterson before Butler High School was opened in 1903. From the time the school opened, the school served students from a area that included Jefferson Township, Kinnelon, Pequannock Township and Riverdale in Morris County, and Bloomingdale, Pompton Lakes, Ringwood, Wanaque and West Milford in Passaic County until they built their own schools or established alternate arrangements with other school districts.Fagan, Matt. "Butler High School's Hall of Honor accepting nominations", The Record, September 12, 2017. Accessed September 13, 2017. "However, between 1906 and early 1960s, Butler was the high school for vast portions of Morris County and northwestern Passaic County and even portions of Sussex County, Wall said.... At one time the high school served as the regional high school for Bloomingdale, Jefferson, Kinnelon, Pequannock, Ringwood, Riverdale, Wanaque and West Milford. Before 1903, when Butler High School first opened its doors, graduates of the Butler Grammar School attended Paterson High School, Butler school board officials said."Frelinghuysen, Rodney P.

"Butler High School graduated its first class in 1907, making the senior class of 2006 the 100th class to graduate from the school. Until 1903, graduates of the Butler Grammar School attended Paterson High School. In the early years, Butler High School was a 'regional' high school in the extreme sense of the word. Originally the school encompassed a territory of more than 200 square miles, providing secondary education to students from Bloomingdale, Jefferson, Kinnelon, Pequannock, Ringwood, Riverdale Wanaque and West Milford. Over the years the sending districts, with the exception of Bloomingdale, withdrew from Butler High School as municipalities built their own high schools or regional districts were created."

Pompton Lakes withdrew in 1933 to open their high school. In September 1954, the Butler district notified its eight sending communities that growing enrollment of borough residents would mean that there would be no space available at Butler High School and that the local districts serving students from Passaic County communities and Pequannock Township would have to make alternate arrangements by 1958.Staff.

Four of these 'sending districts' -- Riverdale, Jefferson Township, Kinnelon and Pequannock Township -- are in Morris County. The others -- Wanaque, Ringwood, West Milford and Bloomingdale -- are in Passaic County. Butler has given Pequannock Township and the four districts in Passaic until 1958 to complete withdrawal of their students." While Pequannock Township, Ringwood and Wanaque met the 1958 deadline, West Milford left four years later, Kinnelon and Riverdale left with the opening of Kinnelon High School in 1962 and Jefferson Township ended their sending relationship with the opening of Jefferson Township High School in 1964."Students Choose 'The Colts,' Colors of New Kinnelon H.S.", The News, April 18, 1962.

The original building occupied by Butler High School was built in the late 1800s and soon expanded with an annex (Still existing, "Annex Building") constructed in 1916. The school then doubled its size with an addition parallel to Bartholdi Avenue in the mid 1930s. After sections of the original Butler High School facility caught fire in January 1963, with damage focused on the portion of the building constructed in 1897, the school was shut down for renovations."Fire Damages Butler School", Courier News, January 15, 1963. Accessed April 8, 2022, via Newspapers.com. "Fire burned through a section of the Butler High School from basement to roof early today causing heavy damage to classrooms and offices. Fire departments from eight communities fought the blaze, which was brought slowly under control after more than four hours. The fire began about 3 a.m. in the janitor's room in the basement and spread throughout the older section of the two-story school. Damage was centered in the original building, which was built in 1897." The gymnasium was unusable due to water damage caused during the fighting of the fire and physical education classes were held outside for the remainder of the school year. Several classrooms in the original 1888 building were also heavily damaged and that building was town down. The school day was increased and the freshmen and some sophomores began classes later in the morning. Trailers were used for the guidance offices, freeing space in the main building for classrooms. The "Art Building" was then built to the left of the original school and opened after 1964.
