NCES Private School Universe Survey, 2021-22 (the most recent federal collection). Private-school demographics are reported biennially and lag public-school data.

Competition evidence

Known results compiled from public competition listings (National Merit press lists, tournament PDFs, The Blue Alliance). A missing result is not evidence of absence.

The real comparison is against your public options.

Tuition here runs five figures a year — the question is what it buys over the public schools your address already gives you. A $29 Research Pass unlocks score trends, peer percentiles, competition evidence, gifted-pathway detail, and PTA capacity on every public school in the region, plus 3 full research dossiers for the schools on your shortlist.
