Summary:
ZIP code 95746 has one high school, Granite Bay High, serving grades 9–12 and enrolling 2,036 students. Its 2025–2026 proficiency was higher than California’s in all three reported subjects: 79% in English language arts, 67% in math and 61% in science, compared with 49%, 38% and 36% statewide. The most important finding is that the school’s advantage over the state was consistent across subjects, ranging from 25 to 30 percentage points.
There is no school-to-school top or bottom comparison in this ZIP because Granite Bay is the only school listed; it is therefore both the group leader and trailer by default. Against the state, it led by 30 points in English, 29 in math and 25 in science; compared with the Roseville Joint Union High district, its margins were 13, 23 and 12 points, respectively. Other reported outcomes also compare favorably with state figures: graduation was 98% versus 88%, while dropout was 1% versus 8% and chronic absenteeism was 7% versus 18%. These figures describe comparisons with state and district averages, not with other schools in the ZIP.
Scores rose in every subject from 2024–2025 to 2025–2026, and the school’s average advantage over the state widened: Granite Bay gained 1 point in English, 6 in math and 6 in science, while state gains were 0, 1 and 3 points; the average school–state gap grew from 25 to 28 points. SchoolDigger ranks Granite Bay 124th of 2,137 schools, in the 94th percentile, with 5 stars. Its student-teacher ratio was 23.8 in 2024–2025, and 25% of students were free/reduced lunch eligible that school year; these are contextual measures, not explanations for outcomes. Because the ZIP contains only one high school, the data cannot show how schools compare with one another or how these measures relate to results across schools.
