Hamilton High School is a public high school in Hamilton, Ohio. It is the only high school in the Hamilton City School District. It was the school in which then-President George W. Bush signed the No Child Left Behind Act on January 8, 2002.
The present building on Eaton Avenue opened as Taft High School in 1959. Taft served the west side of Hamilton while Garfield High School on Fair Avenue served the east. Both were consolidated to form Hamilton High School in 1980.
In 2002, an addition was built across the school's front, giving it new entrances, a new façade, a new library/media center, and six new classrooms. A new fine arts wing was finished in 2004. A recent bond issue approved the construction of a new gymnasium and to convert the old gym into a larger cafeteria. In 2012, the school began construction on the new gymnasium and lunch room. It concluded in 2013.
Hamilton had a high school at the corner of S. Second and Ludlow Streets downtown until 1915 when a new building was constructed at N. Sixth and Dayton Streets. The high school remained there until 1959, when Hamilton's population swelled and two high schools became necessary.
The Hamilton Big Blue compete in the Greater Miami Conference. The Big Blue have captured over 80 conference championships since 1966.
Hamilton has three competitive show choirs: the mixed-gender Prestige, the all-female Vocal Elegance and the all-male CrescenDudes.[6] The school also hosts its own competition, the Double H Showcase.[7]
