Summary:
Six high schools in Fremont Union High serve grades 9–12. Five comprehensive schools enroll 1,630 to 2,224 students, while Community Day enrolls 6; the area’s reported proficiency results are generally well above California’s, but differ substantially from school to school. The most important takeaway is that a district-wide picture can hide a wide gap between schools, especially in math.
Lynbrook High is the clear academic leader, with 93% proficient in ELA, 89% in math, and 87% in science in 2025–2026; it leads the next-highest school by 8, 2, and 5 percentage points, respectively. Cupertino High is another strong performer, particularly in science, at 82%. At the other end, Fremont High scored 58% in ELA, 42% in math, and 42% in science—about 23, 32, and 29 points below the five-school averages, though still above state results in each subject. Community Day’s test scores are suppressed, so it cannot be compared with the other schools on proficiency; its reported chronic absenteeism is 64%.
Recent changes are mixed: the five-school average was nearly flat in ELA from 2024–2025 to 2025–2026, fell about 1 point in math, and rose about 2 points in science. Homestead High improved in all three subjects, while Fremont fell in all three; Monta Vista High also improved in each. SchoolDigger’s statewide ranks shifted from 14 to 12 for Lynbrook and from 362 to 592 for Fremont, though ranks show relative standing, not score changes. Enrollment and student–teacher ratios do not neatly track proficiency: Lynbrook leads with a ratio of 23.1, while Fremont’s is 21.1. The schools’ reported free/reduced lunch eligible shares for 2024–2025 ranged from 6% at Monta Vista to 24% at Fremont; these figures describe context, not a reason for score differences.
