The new board held an election, was organized and soon earned its accreditation from North Central Association of Secondary Schools.
At the time, the athletic teams were known as the "Wildcats”, but in 1929, the BUHS mascot became the "Hawks", narrowly defeating the "Farmers" in a school-wide vote.
[6] The auditorium, the east and west wings, and the gymnasium were added to the original Eason Avenue facility during the summer and fall of 1929.
During the Depression years, with the assistance of the Works Progress Administration, a shop and garage were built, plus additional auditorium dressing rooms, tennis courts, and a football field with lights and bleachers.
The middle of the decade witnessed the old gymnasium torn down and a new one built while the front part of the shop area was rebuilt in 1959.
While the district's enrollment stabilized and averaged just over 800 students throughout the 1980s and the first half of the 1990s,[6] the community showed their support for the school passing bonds in 1980 and 1990.
The funds raised through the issuance of the bonds allowed BUHSD to expand and update its facilities, including the construction of a campus fully networked by computers to meet the current and future education needs of its students.
Groundbreaking for Estrella Foothills High School (EFHS) was held Sept. 20, 2000, and opening ceremonies and classes began on August 31, 2002.
[7] Foothills, as it is commonly called, opened with approximately 150 freshmen, a new mascot the “Wolf”, and is located at 13033 S. Estrella Parkway in Goodyear, Arizona.
Approximately 30 students were enrolled at the campus located in the old Masonic Lodge building on 4th Street and Narramore in Buckeye.
[3] Construction for the new facilities began on January 24, 2003, with the footprint of the new BUHS campus located just east of the football stadium.
BUHS finished the renovation of its current campus by adding a new Performing Arts Center and refurbished Ellis Baseball Field in 2008.
[6] The district continued to grow with the ground breaking of Youngker High School on April 17, 2006, located at 3000 S. Apache Road in Buckeye.
Because of Youngker's close proximity to BUHS, Buckeye Union's student enrollment decreased to 1,499 in 2009 and has since fallen to 1,136 for the 2011–12 school year.
