Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “41% proficient” and call it done. Grossmont deserves a closer read. The school sits in La Mesa, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
