Summary

Atascadero High serves 1,157 students in grades 9–12 in Atascadero, in San Luis Obispo County. Its 2025–2026 results show a clear academic split: English Language Arts/Literacy (ELA) and science are stronger than mathematics. The most important finding is the school’s strong graduation outcome: 98% of students graduated, compared with 95% in Atascadero Unified and 88% statewide.

ELA is the school’s strongest subject against state and district benchmarks, while mathematics is its clearest weakness. In 2025–2026, 55% of students met the ELA standard—6 percentage points above the state and 4 above the district. In science, 40% met the standard, 4 points above the state but 1 below the district. In mathematics, 29% met the standard, about 10 points below both. Among nearby schools with results, Atascadero ranked fourth of 10 in ELA, second of 10 in mathematics, and third of 10 in science. So mathematics trails the state and district but compares more favorably with nearby schools.

Science has improved over time, rising from 34% in 2022–2023 to 40% in 2025–2026, while ELA was nearly unchanged at 55% at both endpoints; results fluctuated in between. SchoolDigger gave the school a 63rd-percentile statewide ranking and 3 stars in 2025–2026, placing it second among nearby schools with current rankings, though its percentile fell 8 points from the prior year. Context: its 2024–2025 student-teacher ratio was 19.5, close to the nearby-school average of 19.8, and 45% of students were free/reduced lunch eligible that year, below the nearby average of 59%. One subgroup result stands out: SchoolDigger’s statewide effectiveness percentile for how well the school serves Special Education Students was 12, compared with 63 overall, down from 76 the previous year.
