15^th

SchoolDigger Rank ?

of 2,135 California High Schools

Better than 99% of California high schools

Summary

Alameda Science and Technology Institute (ASTI) is a 211-student high school serving grades 9–12 in Alameda, within Alameda Unified. Its 2025–2026 test results stand out: ASTI was proficient in about 98% of students in English, 79% in math and 77% in science, with results well above both the district and California in all three subjects. The school’s most important distinction is that it leads nearby schools with reported all-grades scores in every tested subject.

English is ASTI’s clearest strength compared with nearby schools: its result was 19 percentage points above Alameda High, the next-highest reported nearby score. ASTI was also ahead of Alameda High by 17 points in math and 3 points in science. Compared with the state, ASTI’s advantages were 48 points in English, 41 in math and 41 in science; compared with Alameda Unified, they were 27, 17 and 18 points, respectively. Math is ASTI’s weakest subject by proficiency level and its advantage over the district, but its result remains substantially higher than both benchmarks. SchoolDigger ranks ASTI 15th of 2,137 California schools, in the 99th percentile with 5 stars; nearby Alameda High ranks 97th, in the 95th percentile.

Results have risen overall since 2022–2023, though not every year: English increased 7 points and science 11 points, while math gained 2 points. ASTI’s lead over the state widened in English and science but narrowed by 2 points in math. Graduation is also strong at 98%, compared with 96% in the district and 88% statewide, while chronic absenteeism rose from 5% in 2021–2022 to 13% in 2025–2026—slightly above the district’s 12%. In 2024–2025, ASTI had the highest reported student-teacher ratio among nearby schools, at 27.7, versus a nearby range of 8.3 to 23.5. Its free/reduced lunch eligible rate was 45.5% in 2024–2025. These figures provide context, not explanations for the school’s results.
