Lancaster High scores 48 of 100 on SchoolScope's Scope Score — the 45th percentile of 1,739 California high 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 “23% proficient” and call it done. Lancaster deserves a closer read. The school sits in Lancaster, where two-thirds of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 80.0% of students leave measurably college-ready, versus 35.5% statewide.

Worth a school visit
Ask about the discipline philosophy and what a typical suspension is for. Numbers can't tell you whether a campus feels strict or chaotic — a visit can.

This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), 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.
