Gahr High School opened 58 years ago in 1965 as the first high school in both the newly unified ABC Unified School District, and the recently incorporated City of Dairy Valley (the city would be renamed to its current state two years later).[3] The school was officially named after Richard Gahr, who had served as the school district's superintendent. During the 1970s, as the student population in Cerritos rapidly grew, Cerritos High School was created for district expansion, and during its construction the latter used part of the Gahr campus.



As of the school year 2021–22, there were a total of 1,828 students attending the high school.[4]

  • Hispanic or Latino - 52.5% (959)
  • Black - 14.1% (258)
  • Asian - 12.9% (236)
  • Filipino - 10.2% (186)
  • White - 6.3% (116)
  • Other/Unreported - 4.0% (73)


The school is a two-time (2007, 2021) California Distinguished School.[2]
