Private Schools in Simi Valley
Private schools don't participate in California's standardized testing (CAASPP) and cannot be scored or ranked. Showing enrollment, student-teacher ratio, and affiliation where available.
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.
