Summary:

Altadena has five listed schools: four classified as elementary and one middle school, with three of the elementary-classified schools serving K–8. In 2025–26, four schools have all-grades test results; the latest results for Odyssey Charter are from the prior year. The clearest takeaway is that results vary widely: Altadena Elementary leads the current-year group in all three subjects, while Charles W. Eliot Middle is lowest in all three.

Altadena Elementary scored 57% in English language arts (ELA), 50% in math, and 53% in science—about 8, 12, and 17 percentage points above the state, respectively. OCS - South also exceeded state results in all three subjects, at 52% ELA, 48% math, and 43% science. At the other end, Eliot recorded 35% ELA, 19% math, and 16% science, about 14, 19, and 20 points below the state. In the prior year, Odyssey topped the five-school comparison at 80% ELA, 65% math, and 73% science, but those results are not a current-year comparison with the other schools.

Results moved in different directions: from 2024–25 to 2025–26, Altadena improved by 8 points in ELA, 5 in math, and 16 in science, while OCS - South fell by 16, 5, and 13 points. SchoolDigger’s statewide percentile rank for Altadena rose from 62 in 2023–24 to 74 in 2025–26; OCS’s fell from 77 to 64. Staffing ratios do not track results neatly: Eliot had the lowest reported ratio, 16.8 students per teacher, while Odyssey had the highest, 25.7. All five report free/reduced lunch eligible figures for 2024–25: 75% at Eliot, 53% at Altadena, 52% at Mary W. Jackson STEAM Multilingual Magnet Elementary, 29% at OCS - South, and 26% at Odyssey. These figures provide context, not an explanation for school results.
