Diamond Bar High School was founded in 1982 and was the growing city's first high school. Diamond Bar High School is part of the Walnut Valley Unified School District, which was established in 1970. Diamond Bar High's first students were residents that lived in south Diamond Bar (specifically residents that lived south of Diamond Bar's Grand Avenue). It is a dividing line that still exists today. Prior to the opening of DBHS, the area's students were bused from Diamond Bar to Walnut High School. Some of the teachers came from Suzanne Middle School, Chaparral Middle School and Walnut High School. The first principal of the school was Walt Holmes, who came to DBHS from North Monterey County High School in Castroville, California, where he also served as principal.
Diamond Bar High School has a relatively rigorous and competitive atmosphere for a public high school. It is ranked 219 on the US News's Best High Schools in the nation and ranked 39 on the best California high schools.
In March 2013, the Diamond Bar High Symphony Orchestra placed second at the National Orchestra Cup in New York. With the music piece called "Swan Lake," the symphony orchestra amazed the audience, winning several minor awards excluding overall placement.
In April 2013, the Diamond Bar concert percussion ensemble were the Southern California Percussion Alliance PSCO champions (placing first) in San Bernardino, CA, and placed second at the Winter Guard International world championships in Dayton, Ohio. They performed the show, "Star-Crossed Lovers," an arrangement of music surrounding the story of Romeo & Juliet. It was arranged by instructor Gabriel Cobas. In addition, in the same year, the Diamond Bar indoor drumline placed third at the Southern California Percussion Alliance PSA finals, with a show named "Bushido."  
Diamond Bar High School has an award-winning choral program, in which students both compete in show choir competitions around California, and also travel to local colleges and universities to share their vocal skills in festivals. Choirs include Marquis (advanced mixed show choir), Solitaire (intermediate women's show choir), Chamber Choir (advanced mixed chamber), and Diamondtones (concert choir/beginning show choir). Diamond Bar High School has been recognized as the 2014 National Grammy Signature School, thanks to the choral and instrumental music programs at DBHS. 
Pathways is an alternate program offered to students. The program offers different courses and class schedules. The curriculum includes a broad range of college preparatory courses and work experience classes.
