Summary

Los Osos Middle serves 494 students in grades 6–8 in Los Osos, California, within the San Luis Coastal Unified district. In 2025–2026, students scored above state averages in English language arts (ELA), math, and science, but below district averages in all three. The most important concern alongside these academic results is attendance: 22% of students were chronically absent, more than the district’s 16% and the state’s 18%, and higher than every nearby school in the comparison.

Seventh grade is the school’s clearest academic strength, especially in ELA: 77% were proficient, 6 points above the district and 27 above the state, the highest result among nearby schools with seventh-grade data. Eighth grade is less strong: ELA proficiency was 62%, below the district, and ranked fourth among seven nearby schools with results. Across all grades, the school was 17 points above the state in ELA, 16 in science, and 10 in math; compared with the district, it was 1 point lower in ELA, 3 lower in science, and 9 lower in math. Its all-grades results also exceeded those at Templeton Middle and Atascadero Middle in all three subjects.

Results have shifted over time rather than rising steadily: from 2022–2023 to 2025–2026, ELA improved by 4 points and math by 3, while science fell by 7; the school’s science advantage over the state narrowed by 13 points. SchoolDigger ranks the school in the 83rd percentile statewide and gives it four stars; it is second among six nearby schools with rankings, behind Laguna Middle. In 2024–2025, its student-teacher ratio was 18.5, the second-lowest among nearby schools, and 51% of students were reported as free/reduced lunch eligible, the second-highest share among nearby schools with that measure. SchoolDigger’s measure of how well the school serves Hispanic students placed it in the 67th percentile, below its overall 83rd percentile; its measure for homeless students dropped from the 91st percentile in 2024–2025 to the 75th in 2025–2026.
