Summary:
ZIP code 94574 has one listed middle school, Robert Louis Stevenson Intermediate, serving grades 6–8 with 257 students. Its 2025–26 results are mixed by subject: ELA and science are above California averages, while math is below. The key takeaway is that math—especially seventh-grade math—is the clearest concern, despite ELA and science edging above state averages.
Because it is the only school in the ZIP-code list, it is both the highest- and lowest-ranked locally, but that is not a meaningful peer comparison. Compared with California in 2025–26, the school was 3 percentage points ahead in ELA (52% versus 49%) and 3 points ahead in science (39% versus 36%), but 7 points behind in math (31% versus 38%). The grade-level pattern sharpens the picture: seventh-grade ELA was a strength at 55%, 5 points above the state, while seventh-grade math was the largest shortfall at 26%, 12 points below. The school also trailed the Saint Helena Unified district in all three subjects.
ELA improved from 49% in 2024–25 to 52% in 2025–26, widening the school’s lead over the state from less than a point to 3 points. Math was nearly unchanged, moving from 32% to 31%, while the state rose; the gap widened from 6 to 7 points. Science increased from 36% to 39%, though its lead over the state narrowed slightly. SchoolDigger placed the school at the 60th percentile in both 2024–25 and 2025–26 (rank 1,072 of 2,703 in 2025–26), down from the 68th percentile in 2023–24. Context: the 2024–25 student-teacher ratio was 12.5:1, and 42% of students were free/reduced lunch eligible; 2025–26 chronic absenteeism was 8%, below the district’s 10% and the state’s 18%. With one school listed, the data cannot show how it compares with similar schools.
