SchoolDigger Rank ?

of 2,135 California High Schools

Better than 97% of California high schools

Summary

Emerald High serves 900 students in grades 9–12 in Dublin, California, within Dublin Unified. Its 2025–2026 results are strong overall: 85% in English language arts (ELA), 72% in math, and 70% in science. The key trade-off is that Emerald is above California in all three subjects, but its math result is slightly below the district’s.

Emerald’s clearest strength against nearby comprehensive high schools is science: its result is 8 percentage points above the five-school peer average, compared with advantages of 6 points in ELA and 4 in math. It ranks second of those six schools in science and third in ELA and math. Against the state, Emerald is ahead by 36 points in ELA, 34 in math, and 34 in science; against Dublin Unified, it is 7 points higher in ELA and 9 higher in science, but 2 points lower in math. Dougherty Valley High scores higher in all three subjects, while Foothill High is higher in ELA and math.

Scores cannot yet show a trend because the supplied test results cover only 2025–2026. Attendance data show a recent change: chronic absenteeism rose from 5% in 2024–2025 to 9% in 2025–2026, though the latest rate remains below the district’s 12% and state’s 18%. SchoolDigger ranks Emerald 56th of 2,137 California schools, at the 97th percentile with five stars. Its student-teacher ratio is 21.7, below the nearby comprehensive peers’ range of 22.1–24.8. Emerald reported 12% free/reduced lunch eligible in 2024–2025; California is a statewide free-meals state, but this is the school’s reported eligibility measure. SchoolDigger’s statewide effectiveness ranking is notably lower for Hispanic students, at the 39th percentile, and for multiracial students, at the 47th percentile, compared with Emerald’s overall 97th percentile.
