Odyssey Charter: High scores, healthy climate, strong attendance. We looked for a catch — we didn't find one.

Odyssey Charter posts 52.3% exceeding the standard — versus 21.3% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.

Odyssey Charter scores 68 of 100 on SchoolScope's Scope Score — the 90th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Most rating sites would stop at “76% proficient” and call it done. Odyssey Charter deserves a closer read. The school sits in Altadena, where one in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Odyssey Charter's low-income kids hit 61.5% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

As a charter, Odyssey Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.

Frequently asked questions

Is Odyssey Charter a good elementary school?
Odyssey Charter has a Scope Score of 68 out of 100, placing it in the 90th percentile of California elementary schools and ranked #572 statewide. 52.3% of students exceeded the state standard on the 2025 CAASPP assessment, which is 31.0 percentage points above the California average of 21.3%. The Scope Score weights six dimensions for elementary schools: exceeded standard (43%), met or exceeded (22%), grade 3-to-5 growth (15%), chronic absenteeism (10%), ELPAC English Learner proficiency (5%), and suspension rate (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Odyssey Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 76.4% of students at Odyssey Charter met or exceeded the state standard in ELA and Math combined, and 52.3% exceeded it. The gap between those numbers matters: 24.0% of students are at the proficiency floor, while 52.3% pushed past it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it reveals whether a school's curriculum challenges students beyond minimum proficiency or paces toward it. 161 student-subject combinations were assessed.
How does Odyssey Charter rank in California?
Odyssey Charter ranks #572 among California elementary schools by Scope Score, placing it in the 90th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 growth), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.
Is Odyssey Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Odyssey Charter decreases by 9.2 percentage points from Grade 3 to grade 5 growth. This downward pattern doesn't necessarily mean the school is failing — it can reflect cohort differences, demographic shifts, or curriculum changes. A campus visit and conversation with teachers can reveal what the numbers can't. Growth trajectory is weighted at 15% in the elementary Scope Score because it measures what the school does, not just who walks in the door.
What is the attendance and school culture like at Odyssey Charter?
20.4% of students at Odyssey Charter are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 1.2%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
How does Odyssey Charter compare to other schools in Altadena?
Odyssey Charter scores 68/100 (90th percentile) among California elementary schools. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 463 students.
