CDE CAASPP 2025

Most rating sites would stop at “22% proficient” and call it done. SIATech Academy South deserves a closer read. The school sits in Los Angeles, where three in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.

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