Trivium Charter School Adventure scores 50 of 100 on SchoolScope's Scope Score — the 70th percentile of 5,744 California elementary schools (CDE CAASPP 2025).
Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “48% proficient” and call it done. Trivium Charter School Adventure deserves a closer read. The school sits in Lompoc, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 9.8% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.
As a charter, Trivium Charter School Adventure enrolls by application, not address — the score reads the same, the enrollment path doesn't.

What are Trivium Charter School Adventure's CAASPP test scores?

The gap between those numbers matters: 26.9% of students are at the proficiency floor, while 20.9% pushed past it. Most rating sites report only the combined "proficient" number.

How does Trivium Charter School Adventure rank in California?
Trivium Charter School Adventure ranks #1,725 among California elementary schools by Scope Score, placing it in the 70th 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.
