Summary:
ZIP code 93667 has four schools: two high schools, one middle school and one K–12 alternative school, with no elementary schools. Among the three schools with published 2025–2026 all-grades results, the average was 55% in English language arts (ELA), above the state’s 49%, but 26% in math and 24% in science, below state results of 38% and 36%. The clearest takeaway is that performance varies considerably by school and subject, rather than reflecting one shared level across the area.
Sierra High leads in ELA, with 74% proficient—25 percentage points above the state and 42 points above Sierra@Home, at 33%. Sierra Junior High is between them at 58%. Math is weaker across the schools: Junior High has the highest result at 35%, followed closely by High at 34%, while Sierra@Home is at 10%; all are below the state’s 38%. In science, High is at 35%, close to the state’s 36%, compared with 24% at Junior High and 15% at Sierra@Home. Sierra Alternative High has no published all-grades test result for 2025–2026, but its chronic absenteeism stands out at 100%, versus 18% statewide.
Sierra Junior High made the largest gains from the prior year, rising 16 percentage points in ELA, 12 in math and 9 in science; Sierra High fell 2 points in ELA and 6 in math but gained 9 in science, while Sierra@Home improved slightly in all three subjects. SchoolDigger’s statewide percentile ranking rose from 46 to 60 for Junior High and slipped from 76 to 72 for High. As context, in 2024–2025, the schools’ free/reduced lunch eligible shares ranged from 35% at High to 57% at Sierra@Home; student–teacher ratios ranged from 5 at Alternative High to 18 at Sierra@Home. These measures describe different school settings, but the figures do not establish why results differ.
