Summary:
ZIP code 95120 has eight schools—five elementary, two middle and one high—with 5,842 students served across elementary, middle and high school. In 2025–26, the schools’ average results were 78% in ELA, 76% in mathematics and 68% in science, compared with state results of 49%, 38% and 36%. The clearest overall takeaway is that every school scored above the state in all three subjects, though results vary considerably among local schools.
Williams Elementary leads in all-grade ELA and mathematics, with 86% in each; Los Alamitos Elementary leads in science at 76%. At the other end, Castillero Middle is lowest in all three subjects, at 64% in ELA, 55% in mathematics and 51% in science, though those results remain 15, 17 and 15 points above state results. Among the middle schools, Bret Harte Middle scores higher than Castillero by 11 points in ELA, 26 in mathematics and 16 in science.
Area averages rose by 3 points in ELA and 5 in science from 2024–25 to 2025–26, while mathematics changed by less than a point. The area’s lead over the state widened by 3 points in ELA and 2 in science, but narrowed by 1 point in mathematics. School trends differ: Los Alamitos gained 19 points in science, and Guadalupe Elementary gained 10 points in both ELA and science, while Leland High declined in all three subjects. SchoolDigger places all eight schools at or above the 85th percentile statewide. The two middle schools are similar in enrollment—865 at Castillero and 862 at Bret Harte—but their student-teacher ratios differ (22.8 and 21.1), as do their results, so those figures alone do not tell the full story.
