Coronado High serves 999 students in grades 9–12 in Coronado, California, and is part of Coronado Unified. Its 2025–2026 all-grades results were well above state averages in English Language Arts (ELA), math, and science. The important caveat is a sharp 12th-grade science weakness: proficiency was 23%, 10 points below the state rate and 43 points below the school’s 11th-grade result of 66%.
Compared with California, Coronado was ahead by 30 points in ELA, 23 in math, and 28 in science in 2025–2026. Its advantages over its district were smaller: 7 points in ELA, 4 in science, and effectively no difference in math. Among the three nearby schools with comparable results that year, Coronado led in math and science, but its ELA result was below East Village Middle College High. In 2024–2025, Coronado ranked second of 10 nearby schools in ELA and first in math and science; its science result was 63%, compared with 40% at San Diego High.
Since 2022–2023, math proficiency has risen 9 points and science 5 points, while ELA has fallen 6 points from its earlier level. SchoolDigger places Coronado at the 94th percentile statewide for 2025–2026, rank 131 of 2,137, with five stars. Its 2024–2025 student-teacher ratio was 18, close to the nearby-school average of 19. That year, 15% of students were free/reduced lunch eligible, the lowest share among nearby schools reporting the same measure.
