• California institutions in this universe (235 schools).
• California four-year main campuses only. Rank order is published admission rate; on an exact tie, higher SAT average ranks above, and missing SAT does not drop a school. SAT is not shown because it is not the ranked measure. Schools without a published ADM_RATE are omitted rather than estimated.
• Institutions enrolling fewer than 500 undergraduates are excluded — the same size floor as the national selectivity list — even when they report an admission rate. That cut is not a median-stability adjustment.
• 83 of 235 California institutions in this universe qualify for this ranking (report the measure and pass any enrollment floor); the rest are omitted rather than estimated.
