Summary:
ZIP code 90604 has 11 schools: seven elementary schools, three middle schools and one high school. In 2025–26, the average school result was above the state figure in all three subjects—by 6 percentage points in ELA, 5 in math and 2 in science—and 7 of 11 schools were above the state in ELA, 8 in math and 7 in science. The most important finding is how widely results vary: school-to-school ranges were 42 points in ELA, 46 in math and 43 in science.
Meadow Green Elementary led elementary schools in all-grades ELA, math and science, with 70%, 65% and 52%, respectively; its grade 4 results were especially strong at 73% in both ELA and math. Granada Middle led middle schools in all-grades ELA and math, at 68% and 56%, and had 50% in science, close to Hillview Middle at 50%. California High had the highest all-grades ELA result, 71%, and a 99% graduation rate versus 88% statewide, though its math result was just below the state figure. At the other end, Los Altos Elementary had the lowest results in all three subjects: 29% ELA, 19% math and 10% science. Because schools serve different grades, all-grades results are a broad overview; shared-grade comparisons are more useful for choosing between schools serving similar ages.
Recent changes were mixed: the schools’ average ELA result was essentially flat from 2024–25 to 2025–26, while math rose by about 1 point and science by about 1 point; the state’s science result rose by 3 points, narrowing the local average’s lead. Hillview and Howard J. McKibben Elementary improved in all three subjects, while La Colima Elementary declined in all three. SchoolDigger ranked Meadow Green at the 87th percentile statewide and Los Altos at the 15th; McKibben’s rank rose from the 47th to the 52nd percentile. Context measures do not make a simple results ladder: Meadow Green’s student–teacher ratio was 24.7, compared with 20.8 at La Colima, and 2024–25 free/reduced lunch eligible figures were 86% at McKibben and 91% at Los Altos, alongside different test and chronic absenteeism results.
