Plans were made in 1924 to make a separate high school in Brea; some parents pushed back and insisted that their children remain at
Fullerton Union High School. Construction commenced in 1926; despite some shortcomings by the original contractor, the $400,000 project was finished in time for the 1927–1928 school year. The school's initial enrollment was approximately 200 students and at the original location the school had a working farm as part of Future Farmers of America (FFA). By 1989, the school population had grown and the high school needed major renovations. The school district decided to construct the new Brea Olinda High School at 789 Wildcat Way, and it opened in September 1989. The new school location would not include a working farm as part of Future Farmers of America (FFA). ==Athletics==
