Lynbrook High School is a comprehensive public high school serving approximately 1,820 students, grades 9-12, in suburban West San Jose. Opened in 1965 and named for the neighborhood in which it is located, Lynbrook was the fifth school in the Fremont Union High School District and one of three schools the district established during the 1960s. Beginning in the 1970s (not long after Lynbrook opened its doors), FUHSD graduates were instrumental in developing computer technologies that transformed the region into what we now know as the Silicon Valley. Lynbrook’s history is thus closely connected to some of the most profound social and technological developments of our time.

The values enacted by Lynbrook’s community—commitment to family, involvement in the schools, a belief in the importance of education and high academic expectations—directly contribute to the school’s excellent standing. For its part, Lynbrook works hard to meet the needs of its community, and the success of the school’s efforts is evident in our serene, safe, attractive campus; sophisticated approach to technology; collaborative faculty and staff; and extensive co-curricular and extracurricular programs, including state and national award-winning music, dance, drama, speech, and mathematics competition teams and 44 competitive athletic teams. Link Crew, an award-winning peer mentoring program, a staff-run Student Assistance Team, and more than 80 student-run clubs and organizations give all students an opportunity to be connected with Lynbrook High and provide additional support for students and parents. The Associated Student Body sponsors weekly activities during lunch and brunch, spirit weeks, a traditional homecoming week, school dances and evening events.

Lynbrook High School has been named a California Distinguished School six times, and in 2008, Lynbrook was one of 54 high schools nationwide to be recognized as a No Child Left Behind National Blue Ribbon School. In 2011, Lynbrook High School was awarded the Intel School of Distinction in high school science. According to the 2020 Best High Schools report in U.S. News & World Report  Lynbrook High is ranked 10th in STEM (Science Technology Engineering and Math) high schools, 1th within California, and #98 in the National Rankings.
