Summary:
ZIP code 92019 has three high schools serving grades 9–12: Granite Hills High, Valhalla High and Elite Academy. In 2025–26, the two schools with reported results averaged 52% in English language arts (ELA), 27% in math and 33% in science, compared with state averages of 49%, 38% and 36%. Elite Academy has no reported proficiency scores, so those comparisons cover only the other two schools. The most important finding is that math is the clearest shared weakness: the two-school average was 11 percentage points below the state.
Valhalla High leads the reported results, while Granite Hills High has the lowest result in each subject. Valhalla scored 55% in ELA, 31% in math and 41% in science—6, 7 and 17 points higher than Granite Hills, respectively. Valhalla was above the state in ELA and science by 6 and 5 points, but 7 points below in math; Granite Hills was about level with the state in ELA and 15 points below in math and 12 below in science. Elite Academy stands out for attendance: chronic absenteeism was 59%, versus 21% at Granite Hills and 25% at Valhalla.
Recent score changes differ by school and subject: from 2024–25 to 2025–26, Granite Hills gained 3 points in ELA, 6 in math and 5 in science; Valhalla fell 11 points in ELA and 3 in math, but gained 5 in science. The two-school average fell 4 points in ELA and rose 1 in math and 5 in science. SchoolDigger’s statewide percentile ranking also declined over the three years shown, from 75 to 66 for Valhalla and from 53 to 46 for Granite Hills.

Elite’s low ratio does not establish academic performance, given its lack of reported proficiency results.
