No SBAC data for private schools — and that's not the metric you want anyway
California's Smarter Balanced (CAASPP) assessment is administered by the state, by statute, to public & charter schools only. Private schools don't sit for it. That's why the SBAC card is missing on this profile — not a data gap on our side, a deliberate scope of the state's testing program.
For private schools, UC Reach is the stronger academic signal anyway. SBAC measures grade-11 inputs (proficiency on a state standard); UC Reach measures outputs (who actually got into the most selective UCs). For private-school families weighing tuition against college outcomes, the outputs are the relevant signal.
This school doesn't have UC outcomes data on file yet — we surface UCOP-published admits by sending HS, and not every private school appears in those records. The enrollment trend, stability, and other cards on this page are still primary-sourced for this school.
