Summary:
Cupertino Union has 23 schools—18 elementary and five middle schools, with no high schools—and its 2025–26 results show strong proficiency overall alongside meaningful differences among schools. The unweighted average across its schools was 77% in ELA, 82% in math and 73% in science, compared with California’s 49%, 38% and 36%, respectively. Every school’s reported all-grades rate was above the state rate in all three subjects, but school-to-school spreads reached 38 percentage points in ELA, 40 in math and 42 in science. The most important takeaway is that the area performs well above state levels, but the school a family considers can make a substantial difference.
William Faria Elementary is the clearest standout, leading all 23 schools with 93% ELA, 97% math and 93% science; its scores were 44, 58 and 57 percentage points above state rates. SchoolDigger ranks Faria 4th of 5,804 California elementary schools. The lowest results are spread across different schools: Manuel De Vargas Elementary had the lowest ELA at 55%, Chester W. Nimitz Elementary the lowest math at 57%, and Dwight D. Eisenhower Elementary the lowest science at 51%. Among middle schools, John F. Kennedy Middle led in ELA and math, while Joaquin Miller Middle led in science.
Recent results are mixed: from 2024–25 to 2025–26, the school averages fell 2 percentage points in ELA and 1 in math, while science rose 2; the area’s lead over California narrowed in all three subjects. Individual schools also varied: ELA rose at five schools and fell at 18, while science rose at 12 and fell at 11. Other indicators add context, but do not neatly predict scores: Joaquin Miller Middle and Cupertino Middle each enrolled 1,067 students, yet Miller scored 86% in ELA and 91% in math compared with Cupertino’s 74% in both. In 2024–25, the share eligible for free or reduced-price lunch was 13% at Faria and 51% at Nimitz; these figures describe school circumstances, not the cause of results. The data also show that grade-level results can differ from a school’s overall picture: De Vargas’s 3rd-grade ELA was 37%, below the state’s 44%.
