Summary:
ZIP code 95673 has one high school, Rio Linda High, serving grades 9–12 with 1,594 students. Its 2025–2026 results show a mixed academic picture: ELA proficiency was 53%, 4 percentage points above the state, while math was 9 points below and science 10 points below. The clearest concern is science, where 11th-grade proficiency was 12 points below the state.
Because it is the only school listed, there is no local top or bottom school to compare; Rio Linda High is the sole school-level result, not a winner or loser in a ZIP-code comparison. In all grades, it outperformed Twin Rivers Unified in ELA by 17 points, math by 2 points, and science by 5 points, though math and science remained below state results. SchoolDigger ranks the school 1,001 of 2,137, at the 53rd percentile with 3 stars; the district’s separate ranking is 691 of 968, at the 29th percentile with 1 star. For 11th graders, the science gap was especially clear: 27% at the school versus 38% statewide.
Scores improved in math and science from 2024–2025 to 2025–2026, but ELA declined: math rose 6 points and science 4 points, while ELA fell 3 points. SchoolDigger’s percentile stayed at 53rd from 2024–2025 to 2025–2026, below its 60th-percentile position in 2023–2024. Other measures show a notable contrast: chronic absenteeism was 52%, compared with 18% statewide, while graduation was 97% versus 88% and dropout was 1% versus 8%. The school reported 83% free/reduced lunch eligible in 2024–2025, and its student-teacher ratio was 20.3. These are useful context, but the list does not provide another school for comparison.
