What Scope Scores can't tell you about Simi Valley

Numbers tell you whether students are clearing the bar. A school visit tells you whether they're happy doing it. These metrics are intentionally missing from the Scope Score: class sizes and student-teacher interaction quality; arts, music, athletics, and enrichment programs; teacher experience and turnover; campus safety and social-emotional support; parent and community engagement; quality of special education and gifted programs; how school zones and enrollment boundaries affect access.

Unlike single-number ratings, the Scope Score separates students who "exceeded" from those who "met" the standard — revealing whether a school pushes students beyond proficiency or paces toward it.
