Summary:
ZIP code 95404 includes five elementary schools: four serve kindergarten through grade 6, and Santa Rosa Charter School for the Arts serves kindergarten through grade 8. In 2025–26, the five-school averages were 35% in English language arts (ELA), 31% in math and 27% in science, below state results of 49%, 38% and 36%. Results also varied substantially from school to school: the ELA range was 40 percentage points, math 31 and science 15. The clearest area-wide takeaway is that results are below state levels on average, but performance differs widely among schools.
Hidden Valley Elementary stands out in all-grades ELA and math, with 53% and 45% proficient—22 and 18 points above the other schools’ averages, respectively. Those results were also 4 points above the state in ELA and 7 points above in math. At the other end, Kawana Springs Elementary had the lowest ELA and math rates, 13% and 14%, respectively; its results were 28 and 21 points below the other schools’ averages. In science, John B. Riebli Elementary led at 34%, while Proctor Terrace Elementary was lowest at 19%. The charter led 5th-grade science at 37%, while grade-level leaders in ELA and math varied between Hidden Valley and the charter.
Average results declined from 2024–25 to 2025–26: ELA fell 11 points, math 2 and science 5, even as state results rose. SchoolDigger statewide ranking percentiles also fell at all five schools; the largest drop was at Proctor Terrace, from 64 to 29, while Hidden Valley went from 72 to 64. School size and student–teacher ratio alone do not mirror results: Hidden Valley had the largest enrollment and highest ratio (21.6), while the charter had the lowest ratio (19.3). All five schools report free/reduced lunch eligibility for 2024–25, ranging from 36% at Hidden Valley to 62% at Kawana Springs; these figures provide context, not an explanation for test results. All-grades figures combine schools with different grade spans, so grade-level comparisons offer additional perspective.
