Summary:
Zip code 94547 includes five schools in Hercules: three elementary schools, one middle school and one high school, serving students from elementary through high school. Results differ substantially from school to school, and all-grades scores are not fully comparable across schools with different grade spans. The clearest elementary standout is Ohlone Elementary, which led the other elementary schools in ELA, math and science in 2025–2026.
Ohlone had 65% proficiency in ELA, 66% in math and 53% in science; its leads over the next-highest elementary school were 15, 24 and 13 percentage points, respectively. Lupine Hills Elementary had the lowest elementary ELA and science results, at 39% and 31%, while its 42% math result was above the state’s 38%. Hercules High stood out in ELA at 71%, 22 points above the state, but its math and science results were 36% and 35%, slightly below state results. Hercules Middle was modestly above the state in all three subjects: 51% in ELA, 39% in math and 41% in science.
Recent changes were mixed rather than consistent: Lupine Hills math rose 7 points, while Hanna Ranch Elementary science rose 10 points; science fell 7 points at Hercules High and 6 at Ohlone. SchoolDigger ranks Ohlone highest among the elementary schools at the 84th percentile with four stars; Hanna Ranch is at the 59th percentile with three stars, and Lupine Hills at the 50th with three. As context, 2024–2025 free/reduced lunch eligible shares were 35% at Ohlone, 40% at Hanna Ranch and 74% at Lupine; student-teacher ratios were 23.1, 23.3 and 19.6, respectively. Chronic absenteeism in 2025–2026 was 28% at Ohlone and 34% at Lupine, versus 18% statewide—so strong test results did not necessarily go with low absenteeism.
