Summary:
ZIP code 92346 has one listed high school, San Andreas High, serving grades 10–12 and enrolling 420 students. With no other high schools in the list, there is no local school-to-school comparison. In 2025–2026, chronic absenteeism was 80%, compared with 18% statewide. The most important concern is that test proficiency was far below state results in every reported subject: 7% in ELA, 2% in math and 10% in science, versus 49%, 38% and 36% statewide.
San Andreas High is both the highest- and lowest-scoring school in this ZIP-code list by default; its results were below those of San Bernardino City Unified and the state in all three all-grades subjects. Science was closest to the state, with a 26-point gap, while ELA had the largest gap at 42 points; the math gap was 36 points. The 11th-grade ELA gap was larger still, at 50 points. Completion measures are more favorable: the school’s graduation rate was 92%, above the state’s 88%, and its dropout rate was 4%, below the state’s 8%. These results contrast with absenteeism, which was 51 points above the district and 62 points above the state.
Results improved in ELA and science from 2024–2025 to 2025–2026, while math slipped slightly: ELA rose from 6% to 7%, science from 5% to 10%, and math edged down from 2.3% to 2.2%. SchoolDigger places the school at the 15th percentile and gives it one star for 2025–2026, up from the 10th percentile the year before and the 12th percentile in 2023–2024. The school had a 12.4 student-teacher ratio in 2024–2025, and 96% of students were free/reduced lunch eligible that year. These figures offer context, but the available list cannot show how the school compares with local peers.
